Whelen Vortex R4 - all signals
This is the very first activation of Byron, GA's brand new solar-powered Whelen Vortex R4, which is replacing the Federal Signal 500SH-TT on the water tower a couple hundred yards south of the new siren. We tested all six signals shortly after we wrapped up the installation on Sunday afternoon (May 4th), to ensure that the siren functions properly via local control. The Federal 500 is still active as of this posting, but will soon be removed, completely overhauled, and reinstalled somewhere else in the county for additional coverage.

Nelson F200 Big Gun sprinkler
Finally got a chance this afternoon to capture some decent footage of at least one of the three huge Big Guns in action on this particular farm. The road traffic was a bit more than I would have liked, though with that aside the clips seemed to turn out fairly well for what was essentially a spur of the moment situation. This one is a F200, which is the full circle version of Nelson Irrigation's largest model in their Big Gun family of products - the 200 Series. This particular Big Gun has a 1.6" taper bore nozzle with another smaller secondary nozzle located at the base of the elbow for supplemental coverage closer to the sprinkler. Both nozzles have a combined flow rate of approximately 800 GPM at 100 PSI, with a range of about 240 feet on average. If not for the light wind we were having at the time, this big guy is capable of throwing out to around 260 feet with this particular nozzle and water supply.

Tornado Warning with siren - Dickson, TN
Video I shot from inside Charlie (StormChaseTN)'s house, of his Federal Thunderbolt 1000T sounding for a tornado warning at 1am. This was taken in Dickson, TN at approximately 12:37am CST on January 23, 2012, with a reported tornado on the ground. The tornado passed within 1/4 mile of the house, and was briefly seen before it got to us (not captured on video).

Half-Inch Plastic Impact Sprinklers
Here is a compilation of a few different plastic impact sprinklers of various makes and models, all being an above-ground mounted head. First up is an older Rain Bird P2-PJDA-C low pressure impact sprinkler that was made sometime in the late 1990s. These heads perform very well in the lower pressure range where most others fell short, although it does not do well above 45 PSI due to the light arm spring in it. They were one of the simplest part-circle impact designs made by Rain Bird, with very few moving parts and a one piece reverse lever that does not use a spring to trip. These sprinklers are rated for 2.2-4.7 GPM at 10-45 PSI with a range of 24-41 feet. Next up is a rather unique impact made by Naan, known as the model 435 "Topaz" sprinkler. These were once sold in most hardware stores such as Ace Hardware back in the early 2000s, and are a more robust design than the typical cheap all-plastic impact sprinklers of the time. They are incredibly fast rotating sprinklers much like the cheaper models except they have better wear surfaces for a much longer life. The 435 was rated for 2.6-5.6 GPM at 15-65 PSI with a range of 34-48 feet. Third in line is the once-popular Beta-II plastic impact sprinkler made by L.R. Nelson. These were once a very common sprinkler to find in use on many lawns across the country, mounted on many different types of hose-end sprinkler bases. They also came in a popup version during that same time period and were pretty popular in certain regions of the country. These Beta-IIs were of great quality for their time being made of all plastic components and aren't nearly as fast as most other plastic impacts out there. These were rated for 2.9-4.0 GPM at 30-60 PSI with a range of 36-43 feet. Last (but not least!) is one that anyone else would have probably thrown out due to the broken arm but as you can see it still keeps on kicking. This is an older cheaper plastic impact sprinkler made by Lego/Water-Whiz back in the 1990s and early 2000s, which is a model 7220 with the blue fixed nozzle installed. These were once sold in most home improvement stores (mainly Lowe's) before Lego/Water-Whiz went out of business, and also came in a popup version known as the model 7329. These were rated for 2.0-3.4 GPM at 20-60 PSI with a range of 32-40 feet.

Rain Bird 65D impact sprinkler
It's not often that one sees this more modern style of a Rain Bird 65 series sprinkler with a regular "spoon" drive arm instead of the currently standard anti-backsplash (PJ) drive arm. This particular 65D-TNT was originally used as a larger radius secondary end gun on the end of an old center pivot machine, which is used in conjunction with the larger main end gun to help fill in the coverage gap that they often create. This one is a later model that shares the same overall upper body and bearing assembly as the current 65PJ-TNT uses, with the only notable exceptions being the obviously different drive arm type and older friction/trip collars it has. For this run I used a 11/32" nozzle with a plastic stream straightening vane behind it, which was putting out around 25 GPM with 50-55 PSI at the nozzle and I'd say it was throwing out there somewhere in the ballpark of 70 feet.

Rain Bird 95 impact sprinkler
Here's one Rain Bird sprinkler that some of you may have not ever seen before, and there's only one other video of one of these in operation on YouTube to date (that I know of). This was Rain Bird's biggest part-circle impact ever made, the #95. It features a 2-inch threaded connection with three nozzles for covering different ranges throughout its radius of throw. The main nozzle has somewhere around a 1/2" orifice, the drive nozzle is 7/16", and the spreader nozzle under the main nozzle is 1/4" with an adjustable diffuser screw from a #65 impact. I can't remember exactly how much output this guy has with that nozzle configuration, but it's somewhere in the ballpark of around 150 GPM. The pump that's pushing it is my engine-powered Pacer 2" trash pump, which unfortunately has a pressure output of only around 45 PSI so it's not the most impressive looking pattern, but it works!

Rain Bird three-quarter inch impacts
Huzzah, I'm still alive! :) Since I had to finally drag the portable PVC sprinkler line out from its resting place this evening, I figured I'd make a quick little video of some good old Rain Bird brass impacts in action. From the view at the very beginning of the video, at the far left is the 35A-PJ-TNT (part circle), in the middle is a 40B-TNT with the rear spreader port plugged, and the far right is a 14070-TNT, which has a 1/8"-20º spreader nozzle in the rear nozzle port. All three impacts have a 3/16" (ADJ-3) main nozzle with the adjustable spring-loaded diffuser screw. Not sure why that 40B likes to do that little double-tap with its drive arm, but for whatever reason it's always done that even though it works and waters perfectly fine otherwise.

Federal Signal Thunderbolt 1003 - Fire Signal
First test of the Thunderbolt 1003 in Electra, TX after replacing the chopper motor. The rotator switch was accidentally left in the off position after working on it, which is why it wasn't rotating in the beginning. I had to run over from where the camera was and flip it back to the automatic position once we realized what happened.

Buckner IB series impact rotors
For anyone wondering if I had any plans for those brass Buckner popup impacts I've recently posted videos of, this should answer that for you. I recently split up the two zones at the controller that were formerly all Rain Bird impacts (mostly Maxi-PAWs) in the backyard so I could have better control over the middle area that needed more water than the perimeter, and opted to replace two of the three Maxi-PAW impacts in the middle zone with two larger impact rotors that could handle the higher pressure and flow on such a short lateral line. The part circle head is the IB-101 from my last video, and the full circle head is the IB-100 from a few videos back. Some "tech specs" for the zone... • 55-60 PSI at each head with 25-26 GPM total flow • IB-101 (PC) has a #12 (3/16") straight-bore nozzle - approximately 7.5 GPM flow and ~55-foot radius of throw • IB-100 (FC) has a 11x14 nozzle setup from a Rain Bird 51DR golf rotor - approximately 18 GPM flow and ~60-foot radius of throw

Nelson PC100 Big Gun - Overview & Run
Sorry for the lack of editing, my video editing software decided not to render the transitions between each clip. As stated in the video, I've been asked a lot lately about how these "Big Gun" sprinklers work, so I figured I'd make a much better video with a more in-depth view of the setup. The sprinkler used this time is an older model (circa late 1970s) with the "fast-reverse" setup to make the gun part-circle; newer models are "slow-reverse" that move the same speed in both directions. Enjoy a look at a piece of irrigation technology from yesteryear!

Fun with a Thunderbolt Blower
For those of you that ever wanted to see the inner workings of a Roots 4M blower (aka the Thunderbolt's compressor), here you go. This blower is rated for 250CFM @ 3-5psi. It has a 10hp three-phase Lincoln Electric motor with the 3-belt setup driving it. This is a Series A2 blower, same exact blower as the B and C series blowers, only with a different pulley configuration.

Federal Signal Thunderbolt 1000T - Monthly Test
First run of my 1976 Federal Signal Thunderbolt 1000AT, in conjunction with Houston County's 33 Whelen WPS-2900 sirens, for the monthly test. This run was with the chopper only (no blower or rotator), and the chopper is set to terminal 3 on the transformer. I was approximately 100ft from the siren in my backyard, and the closest two Whelens are a little under a mile away each. The wind was blowing from the wrong direction again today, so the Whelens aren't very audible as they normally are, but you can still faintly hear them before the Thunderbolt winds up.

Federal Signal 500 & Whelen Vortex R4 - Byron, GA
After finally diagnosing the coding issue with the new Whelen Vortex that was installed to replace this old 500SH-TT siren, both sirens got to run today for the first time simultaneously. Both sirens ran for just under a minute and a half of the steady (alert) signal at noon, in conjunction with Peach County's weekly siren test. For those wondering, the 500 still has an edge over the Vortex in terms of loudness, but the Vortex's sound will definitely propagate further than the 500 does because of its smoother tone, versus the raspiness of the 500's sound. It was incredibly loud at times from my vantage point when both sirens swung around to point my direction at the same time, definitely made my ears hurt a bit! Also, the thought never occurred to me at the time of the recording to even once pan over to show the Vortex, so I apologize that it's not seen in the video but it's obviously very clearly heard throughout. The Vortex is located about 500 feet east of the water tower behind the Byron Fire Department. And no, the 500 will not be switched off nor removed from the water tower anytime soon as the county hasn't allotted the funding just yet to at least remove it, so the two will continue to run together until that day arrives. If the bulk of the city's population can't hear a siren outside with these two running, they're obviously deaf!

Federal Signal Model 2 - Growl, Alert, & Attack
First off, HUGE thanks goes out to Tyler (antiwhoknows) for editing the video for me while my computer is down and out. This is the monthly test of Houston County's outdoor warning siren system, as well as my privately-owned Federal Model 2-240. My siren is now on a new "perch", right at about 15 feet from the ground and on an actual utility pole instead of a 4x4 post. The siren does a double growl during the pre-test voice messages as a heads up to anyone in the immediate area, and is then followed by a 30sec alert tone alongside the county's sirens, and finally a ~30sec attack signal, usually consisting of two cycles.

Federal Signal STL-10A
First test run of a rebuilt 1950s STL-10A. The siren has a 15hp three-phase GE motor. We had to put one of the side doors from a Thunderbolt over the intake to cut down resistance so Jeb's generator would start the siren's motor. Before we fired up the Thunderbolt, this was the loudest siren we'd ever run at his house!

NaanDan Jain "Mini Revolver" sprinkler
Here's an odd little ball drive sprinkler that I'm sure many of you haven't ever seen before (nor had I before this one). This is the Mini Revolver (aka "Mamkad 16") sprinkler, made by Jain Irrigation under the "NaanDan" division for use in agricultural irrigation systems. These are considered to be "mini sprinklers" due to their low volume water output and relatively short coverage diameter, and are recommended for use on fixed risers (as shown in the video) or on their "IrriStand" stake assembly for poly tubing systems. The one shown here is the standard angle model with the smallest nozzle available (blue), which has a flow range of 0.60-0.86 GPM at 30-60 PSI and a watering diameter of approximately 42-46 feet. These little sprinklers have great coverage from the nozzle all the way out to the end of the stream and take very little water to operate. For more information on the "Mini Revolver" and other rotating sprinklers made by NaanDan Jain, follow the link below to view the technical brochure: http://docs.google.com/viewer?url=http://jainsusa.businesscatalyst.com/_literature_149112/Rotating_Sprinklers Be sure to check out NaanDan Jain's other great products for the agricultural irrigation industry by clicking the links below! http://www.jainsusa.com/ http://www.naandanjain.com/

Hand Move Irrigation System
Finally had some time to stop and get a decent video of this awesome irrigation system behind Lane Southern Orchards. If you love watching those "retro" brass impact sprinklers still being used for one of their original applications, then sit back and enjoy the show! This is the portable (or "hand move", as it's called in the industry) irrigation system that's put into place around the first week in July each year to water a special little cornfield behind Lane Southern Orchards in Fort Valley, Georgia. This small cornfield will eventually become Lane's highly popular corn maze that they open up during the month of October, which coincides with the kickoff for harvest season for the bulk of row crops grown in the area. Each year between June and July, they plant the field with corn using GPS-guided equipment, and come late-September they begin grooming the crop canopy to resemble an image as seen from overhead, which forms the maze itself. The images are typically themed for different causes (i.e. breast cancer, Downs syndrome awareness, etc), and at least a large portion of the proceeds from the maze will go toward one or more nonprofit organization that the field is themed after to help with their cause. Now onto the specifics about the irrigation system itself! The original setup was once mostly Rain Bird 30WH and WeatherTec 10-30D brass impact sprinklers, but now also includes a growing handful of Senninger 5023 thermoplastic impact sprinklers to replace the old brass heads as they break down. The sprinklers are all mounted on 8-foot tall PVC riser pipes that are tied off to T-posts for stability, and are fed by a 3" aluminum pipeline laid along the ground with outlets spaced every 40 feet. The lateral lines are spaced approximately 40 feet apart, with staggered sprinkler placement from one lateral to the other to make a triangular spacing pattern for the sprinklers. The closest one that I zoom in on at least once is one of only a couple WeatherTec 10-30D brass impacts, while the other brass impacts found randomly in the system are Rain Bird 30WH heads. The pump can only supply enough water to run two laterals at once, which is why if you look closely toward the end, you can see a ball valve at the point of connection for each lateral line where it feeds from the underground supply line. They usually switch out which set of laterals runs each day, and as far as I can tell they pretty much run them all day long.

Sprinkler System Tour
First off, in case anyone wants to skip through any portion of my ramblings, the different zone clips start at the following time marks: ZONE 1: 0:00 ZONE 2: 4:12 ZONE 3: 8:19 I had originally planned on doing a better quality video of the three main zones in the system today but I didn't have enough time to do it this afternoon so this is the next best thing for now. These clips were recorded about two weeks ago on my iPod Touch before I switched controllers (see previous "Sprinkler System Update" video to see it), but other than the controller swap-out everything else is the same now as it was in these clips. I do have more zones than the three seen here but the zones covering the majority of the outermost part of the backyard have been broken for many years now and we just haven't had the time or money to invest in repairing it yet. I'm planning to make a "part two" of this video in the near future showing off the manually operated zone across the driveway out front (three green Rain Bird Mini-Paws), as well as how I normally water the rest of the backyard during the growing season. The latter part might be a while since it's somewhat labor-intensive to set up my hand-move system that waters the back, but I still plan on taking the time to set it up and show it off. Thanks for watching and stay tuned for the next update!

Clinton, SC siren ambiance
Took this video last Saturday (Feb. 7) while we were in Clinton, South Carolina picking up some siren parts. Laurens County tests their siren system every Saturday at noon, which consists of several Federal 3T22s (mostly single phase models) at each of the county fire stations, and a Federal STH-10 (single phase) with a Whelen WPS-2902 at Presbyterian College on the western side of Clinton, and a Sentry 10V at the Whitten Senior Center on the east side of Clinton. The two main sirens heard in this recording are the 3T22 in downtown Clinton behind the public safety building running the steady alert signal, and the sickly-sounding STH-10 at the college running the wailing attack signal. Also, if you listen closely, you'll also faintly hear the Sentry 10V wind up after the STH-10 first starts up. We were about a quarter of a mile from the 3T22, and about a third of a mile from the STH-10, with the 10V being just under two miles away.

Valley 7000 Series Center Pivot
Here is a two-span Valley 7000 Series center pivot irrigation machine in operation, providing water to a thirsty mid-season corn crop on a windy day. You'll notice that the first half is without the end gun running, while the second half was taken once the pivot got far enough beyond the nearby road to activate its end gun. The main focal point on this particular pivot is the new Nelson Irrigation "R55" end-of-pivot Rotator sprinkler, which has just recently hit the irrigation market within the last year. Very efficient and cool-looking sprinklers, sort of like a giant version of the MP Rotator nozzles seen in many landscape irrigation systems out there. The pivot itself is outfitted with standard-angle Senninger iWob-UP3 sprinklers on blue hose drops with 10 PSI pressure regulators. The end gun is your typical, run-of-the-mill Nelson Irrigation SR-100 Big Gun sprinkler, fed by a 5hp Berkeley booster pump.

"Passing of the torch" - Outdoor Warning Siren Commissioning & Decommissioning
Old siren starts at 0:05, new siren starts first test at 3:05, new siren runs final test at 6:18. **SEE DESCRIPTION BELOW** The final run of the town of Yatesville, Georgia's old 1926 Federal Electric Type 7 siren, which was replaced by the refurbished 1964 Federal Sign & Signal Thunderbolt 1000T that sounds off second and third. The old siren (Type 7) was originally purchased in 1927 by the City of Thomaston as a fire siren to call volunteer firefighters to action, and was later moved to Yatesville around 1970 to serve as their fire siren until the department purchased a radio system, which then the siren was added to the county siren network for severe weather warnings. The replacement siren (Thunderbolt) was originally in service in the City of Norman, OK as part of their former outdoor warning system, and was brought back to GA to be overhauled and put back in service. This siren was refurbished both mechanically and cosmetically over the winter by McCranie Warning Systems of Rhine, GA, and installed on March 1, 2014. After this test, the old siren was removed from its pole and taken to its new home at The Rock Ranch in The Rock, GA to be stored until it can be cosmetically refurbished to be displayed alongside "Molly", the City of Thomaston's first fire truck that was also purchased at the same time as the siren. For those interested, I was set up in front of the Yatesville Public Library about 330 feet northeast of the two sirens' location. Both sirens were installed right in front of the Yatesville Fire Department on Childs Avenue, on either side of the pump house. Now only the pole remains from the old siren, which will be re-purposed for mounting the department's radio repeater antenna to get it up higher in the air.

Sime "River"(P-190) sprinkler
So I just realized that I hadn't ever uploaded any videos of this awesome Italian-made rain gun sprinkler before, at least not on YouTube. I decided to record a couple of different clips while it was doing its thing and watering the outer part of the lawn over this past weekend. I've had this sprinkler for years but it doesn't often get dragged out anymore since there's quite a bit of labor involved with hooking everything up. This is a turbine-driven rain gun, called the "River" (I have also seen it listed as a "P-190" before) and is made by a company called "Sime" out of Italy. These guns are incredibly popular in Europe, and are really starting to catch on here in the US due to their zero vibration as compared to any other impact-driven gun sprinkler (i.e. Nelson Big Gun, Komet Twin Guns, etc). The built-in stream diffuser arm does incredibly well with filling in under the main arc of water intermittently when the cam wheel moves the arm into the stream momentarily. On this setup I have a 12mm(0.47") nozzle installed on the gun, which puts its output right at about 62 GPM at 58 PSI at the gun. If it weren't a bit windy that day, it will normally throw out around 80-90 feet on a calm wind day. For more info on the sprinkler in the video, check out Sime's brochure on the River sprinkler: http://www.sime-sprinklers.com/pdf/Turbina/04%20River.pdf For Sime's full lineup of sprinkler products, head on over to their main product page to learn about the other gear- and impact-driven sprinklers they offer. http://www.sime-sprinklers.com/enirrigatori.htm

Whelen Vortex R4 - "noon test" & air horn
Here's a couple of clips I took after we (McCranie Warning Systems) performed maintenance on a Whelen Vortex in Upson County, GA. This unit previously kept going off at random in wail, due to a faulty ribbon cable connecting the user interface keypad and the motherboard. Once all the new components were reinstalled and hooked back up, we briefly tested the siren in a one-cycle wail signal (also known as the "Noon Test" function), and one blast of the "Air Horn" signal.

First full run of Jeb's Thunderbolt 1000BT (aka the "blunderbolt") with the roots blower off of an A2 series Thunderbolt. We didn't quite have the head bolted down all the way on the flange, so only about 75% of the output air was going through the chopper. It was still painfully loud as you got closer to the front of the horn!

Federal Signal 2001-SRN - "growl" tests
A collection of a few video clips I took after we (McCranie Warning Systems) performed some overdue routine maintenance on three different Federal 2001-SRN sirens in Jones County, GA. The batteries in all three units needed changing out (last changed in 2007), so we briefly tested each unit after fresh batteries were installed to verify the functionality of the battery backup. These units are AC/DC operated units, meaning they normally run on rectified AC power until it is lost, and then switches over to the battery backup pack until line power is restored.

Whelen WPS-2910 ambiance - Norman, OK
*This was originally recorded on Saturday, April 27, 2013 at 12:00pm CDT. Wasn't going to record the test at first given the wind and the distance I was from the closest siren, but Cory and I figured it'd be worth a try. This was taken from Max Westheimer Airport in Norman, which was pretty much smack in the middle of three of the sirens. The one I'm zoomed in on in the video is the one near Norman North High School on Stubbeman Avenue.

Whelen Engineering Vortex R4 - Macon, GA
Went back to the Whelen Vortex at the industrial park in the south end of Bibb County to see how well it works now that it had been repaired since the last time I came here a year ago. The last time all it did was rotate just a tiny bit clockwise and emitted a loud "POP" sound from the drivers. Likely cause for the earlier malfunction was due to dead batteries, thus not having enough voltage/capacity to operate the siren. Works great now, and actually even acknowledges the cancel code correctly and shuts off like it's supposed to! Also notice how when the activation command was sent out a second time, the siren briefly pauses and restarts its signal.

Champion Irrigation U61-AP
Here is another video of the Champion brass impact sprinkler, this time with the brass impact head (U61-AP) taken out of the popup canister and mounted to a riser. This better shows how the head itself works without the lid and case obscuring the view. The whole sprinkler is practically brand new with very little use, as evident by this video. It's basically almost identical to a Rain Bird #25-PJ or a Nelson Alpha II PJ impact sprinkler, in both design characteristics and performance.

Toasty Single-Phase ACA P-15
First and last run of what was supposed to be the new siren for Milan, GA. The siren was apparently fried before it was taken off its pole at its original location (Darien, IL), but we were told it ran. Technically it still runs, but it spews smoke from the burning wires in the motor field and armature, and gets so hot after running 10 seconds that you can't even touch it. Smoke can be seen coming from the back drain ports of the motor during the wind down of the second run-up. Photos of the P-15 can be seen at: http://s208.photobucket.com/albums/bb149/mrboy29/Siren Pics/Milan P-15/

Hunter Institutional Spray and PGP - clear demo models
While these may otherwise be fairly common sprinkler models to find in use, I'm sure many people have never seen these special production demonstration models made of a clear acrylic. I was given both of these heads by the regional Hunter representative many years ago when I was a kid, but never got around to making a video of them running before. The first one is a 4-inch popup Institutional Spray body with a Hunter MP3500 MP Rotator nozzle installed, and the second is the ever-popular PGP popup rotor with an old style #9 red nozzle installed. The Institutional Spray series was the higher end spray body lineup that Hunter offered in the early 2000s prior to incorporating its features into the Pro-Spray line, including a 30 PSI in-stem pressure regulator and a factory-installed check valve at the base of the popup riser. They are otherwise virtually the same as the Pro-Spray series made today, using the same components that the Pro-Spray has (i.e. body, cap, molded wiper seal, etc). The demo model featured in this video was made in April of 2000. Aside from the see-through acrylic construction of the head seen in this video, the PGP is nearly the same as the traditional PGP-ADJ model still in production today aside from a few improvements to the reversing mechanism and some other minor design tweaks. In this demo model you can see how the entire drive assembly works, from the turbine drive at the base of the riser through the reduction gearbox and up to the rotating turret. This just goes to show how simple the design is inside of most any modern gear-driven rotor sprinkler on the market today, and why they are so reliable for many years of service.

ACA Howler - 2009 Tornado Drill - Macon, GA
I apologize in advance for the all over the place, shaky video. It was really cold and windy that day so we were sitting in the truck without a tripod and my hands were pretty shaky. Finally managed to find and fix/edit the video file from back in 2009, when Jeb (Blue10AEMia) and I went up to Macon to finally hear their ACA Howler up close after several failed attempts. This was likely one of the last times this siren ran, as sometime between this recording and the next time I went back to get a better video of it, the siren was struck by lightning and burned up the motor. This siren has long since been removed, and now resides at Jeb's house still awaiting a new home so it can be finished up and re-installed. Enjoy!

Thunderbolt RCM1A and AR Timer demo
So here's the other promised video, of the RCM1A and AR timer that came with my newest Thunderbolt. At first, the heaters and contactor coil magnets were kind of screwed up from being rained on and exposed to the elements for 4 months straight, but I got them all cleaned out and put back together. Luckily, the SiraTrol box was kept closed, which kept the AR and counter in excellent condition. Everything now works as it should, and all that remains left to do (besides painting everything) is just to get the old standpipe piece out of the blower elbow, and get the special top pipe cut and re-threaded. Stay tuned for more updates as things happen!

Federal Signal 2001AC (broken rotator) - Macon, GA
Federal 2001AC (SRN-style) siren located at the corner of Houston Road & Walden Road, on the property of Glen Haven Memorial Gardens. Shortly after activation, I could tell this siren was going to be trouble, due to it starting off rotating just a hair, then coming to a stop. And yes, before anyone asks, I did contact EMA right after the siren wound down to notify them of the broken rotator.

ASC T-128 - Alert Signal - Hubbard, TX
**READ ME** Second (alert/steady) test of the freshly-overhauled and installed late 90's American Signal T-128 (AC/DC), painted a custom "Civil Defense" yellow with CD decals, per the town's request. This overhaul/installation was orchestrated by Bryan D (mixerbd699), and Jeb and I were called upon to help get the siren ready and install it. This test was the first activation from a remote push-button station that was installed inside the fire department for ease of activation, as well as to try out the different siren signals to see which one worked the best for which scenario. They will be using this siren for both fire calls as well as weather warnings, though the fire signal will not be used as it was proven ineffective due to the cycle timings with rotation speed. Bryan and I were about 1/4 mile NNW of the siren for this video, standing at the location of Hubbard's former fire/weather siren (a Sterling M5). The Sterling's motor finally quit working from deteriorated insulation, which is why they had this T-128 purchased and installed.

Nelson Irrigation SR-150 pivot end gun
Took some time at lunch to stop by Super Sod's SR-96 farm to shoot video of their 7 span Zimmatic center pivot watering the sod fields, most specifically the unusually large end gun at the end of its overhang. The pivot has an 88-foot overhang pipeline with a Nelson SR-150 21º Big Gun sprinkler at the end, with its water supplied by a 5hp Berkeley booster pump mounted beneath the "rabbit ear" cable tower for the overhang. The pivot itself is just your typical standard Zimmatic Generation 2, which has Nelson D3000 spray heads on 10 PSI pressure regulators mounted on poly drops just below the span trussing. Looks like the large end gun really gives the overhang a workout with all the bouncing around from its thrust force.

Thunderbolt number 2 (ex-Macon Station 104 siren)
Finally just got this bad motor scooter home yesterday, and decided to do a quick walk-around video of all of its components before it got too dark. I plan to make another, more in-depth video tomorrow of everything opened up and all, and of the controls, so stay tuned! In case you couldn't tell it, this is the Thunderbolt from my two videos of the one being tested in Macon, at the Macon-Bibb Fire Station #104 on Mount Pleasant Church Road. It was replaced with a Whelen Vortex back in November of last year, and I was waiting on clearance to pick it up between then and now.

Federal Signal Model 2-240 - Monthly Attack Test
Monthly run up of my Federal Sign & Signal Model 2-240, in conjunction with the county-wide outdoor warning siren test. The Whelens were not sounded due to being tested during the statewide tornado drill on the 3rd, but I decided to go ahead and test mine anyway. Signal used for tests is 3 cycles of the attack signal, which is about 30 seconds long in all. Dillon Prater (lildil39485) was down here for the Whelen's test, but since it failed we decided to go catch the Model 2 going off at my place.

"Add-On" impact zone update
Quick update video on the three green LG-3 (15103) Mini-Paw impacts on the side lawn, showing the recent head replacement on each of their internal assemblies. As noted in the video, I used three of those P5-R riser mounted impacts from the local hardware store to "rebuild" the top end of the popup internal assemblies so that they now have the single weighted drive arms that work better on lower pressure. I also installed the smallest (red) nozzle in them to maximize the available pressure at the heads, which seems to have helped quite a lot. They'll have to run a bit longer now to achieve the same application of water as before, but that's no big deal.

Rain Bird TDR sprinkler (older green model)
Here is another old Rain Bird "R-50" rotor of mine, however this one holds a special place in my life as it is the first sprinkler head I ever bought new back when I was about 5 or 6 years old. It's seen its fair share of use over the years and is starting to show it by the small leaks seen during this run, mostly where the top seal meets the body and leaks from under the body cap. These older models don't have the adjustable bypass stator for the different size nozzles like most later R-50/TDR-2s have; they utilize a removable poppet that restricts the water flow through the drive to match the nozzle size installed. This one has the typical gray 3.0 GPM "radius plus" nozzle and matching poppet installed, which has a spray radius of about 40 feet.

Working on a Federal Signal 2001
Per viewer request, we actually had some time while working on a siren where I could film some of it. Just us in our "natural habitat"! For those wondering, this is the Federal 2001-SRN at the River North water treatment facility in western Jones County, GA. We were replacing a dead battery charger in the unit.

Buckner #512 Rocker Jet sprinkler
Finally caught a break with the weather and managed to get a decent video of my newest acquisition, a Buckner #512 "Rocker Jet" sprinkler. This Rocker Jet is in very good condition for its age and appears to have seen little use over its lifetime. It also appears that it never had the diffuser screw attachment installed on the nozzle like most seem to have, though I'm not sure why that is. This one has a 7/32" nozzle installed and throws out at least a good 45 or so feet while being mounted at ground level, and I would guess that its output is somewhere around 9 GPM with 45-50 PSI at the nozzle. I initially had it running with a bit higher pressure than what it has in the video, but I noticed that at higher nozzle pressure it tends to kick the arm down a bit too hard and strikes against the small tab that keeps the arm from traveling too far back, thus making it "short stroke" a little much for my liking.

Toro 640 Series sprinkler
Another older video I took in 2014 shortly after I got this one. This is a Toro 640 Series gear-driven rotor, which is still made today and is still one of the best 1" commercial rotors on the market. The one seen here is specifically a "641-02-42", indicating that it has a 90° fixed-arc drive assembly and a #42 nozzle, and was running here at about 15 GPM with close to 70 PSI. One of the main reasons these rotors are so popular and last so long is due to their non-adjustable arc, which is changed by swapping out the entire lower drive assembly. They are offered in the standard 90, 180, 270, and 360 degree patterns, as well as basically any "specialty" patterns from 45° through 335° in 15° increments. They also have four different nozzle/stator sets available (#40-44) with flowrates from 6.0-25.0 GPM.
