My high school use to have an Edwards system with 1251-0A’s installed with Edwards 360-A flush mounted horns originally. It was a coded system using the code 14 on the 1251’s since asking Edwards to make custom stations was more expensive. They also had the glass break rod tamper switch. Most boxes for the 1251’s are still left in with the wires being cut at the base instead of being pulled out. There are TONS of empty pull station boxes installed, and most horns still installed, although deactivated. They did this to save money and since it was required to take the pull stations out. The old Edwards system was upgraded to a Firelite system in the early 2000s, with p2475’s and addressable bg-12’s, which was recently upgraded to a new FireLite addressable system with about 5 p2475’s still in service, about 12 advances, and about 7 P2RLED. Going back to earlier, a newer seperate building was built in the 90s, and used a Simplex system with Simplex 2903-9101’s with 2901-9838’s. They also used old simplex T-bars i couldn’t get a photo of, with only the horns still installed, but the simplex system was recently removed. Funny enough, a 2903 failed back in the 2010s and got replaced with a terribly retrofitted advance. They likely used a 4001 panel in the begging. That same section with the simplex system got a new hall in 2010 with a FireLite system with Advances, and addressable bg-12s. They connected that new system to the 4001. Now, they added more to the addressable system, removed the simplex devices and system and put new led p2rled’s, a few L series xenon strobes weirdly..? and left the one terribly retrofitted advance back in place and replaced the t bars with some original bg-12s and some newer bg12s. Nowdays, everything is a whole. Parts use voice evac, with no messages, just tones, and some places use horns like the advance series. There are 2 panels connected to eachother now. One in the original 70s building that is now connected as a whole, and one in the 90s building that is now a whole.
Neat. Any chance you could not only save what’s left there (including the 1251s’ backboxes as those are particularly rare to find) but also potentially find where the original coded pulls went off to? (if they even still exist of course) What panel manages the system now by the way?
I assume that you blacked out the bottom-left corner of the 2903 because it had one of those inspection stickers on it that could reveal the location of the school, right?
Just like the 1251 that thesdx had huh? Wonder why some had that instead of an actual code…
If i could, i would. I don’t think my school would like it if i removed them since they don’t feel like patching all the walls and removing all the cables since there are so many boxes. They actually left all the cables in the walls and cut them at the boxes instead of pulling them out. I would 100% try to save all the horns and the boxes since the boxes for the flush mounts are very hard to find.
I don’t know where the original system was to the building. Funny enough, there were 2 separate buildings originally. they might have had 2 different systems or the most likely answer- just had one and ran wires underground to the other system. the old system was likely taken out, but i can’t trace where it goes since the wires are in the walls and ceiling.
Likely a newer addressable panel like a ms-9600. I saw it in a room before, and it looked exactly like that. For privacy, i don’t want to describe too much details, but my school is one big whole now and parts of it are horn strobes, and parts are voice evac speaker strobes, but just play the acc 50/100 beep noise with no message. My school has 2 panels connected to eachother.
Yes, that was an inspection sticker.
They had that so the installer could remove or clip off the specific notches to make their own code. asking Edwards to make it with an engraved tag and custom code was likely more expensive. I guess they decided to leave them all on 14.
I will be kinda rewriting this to make it a little more understandable. Also, on a scale of 1-10 how rare are the flush mount grey horns? I just found the only one listed in months and bought it. Most 360-a’s are red, and i have never seen a grey one listed on eBay. Most are the common 384’s.
Alright. Shouldn’t hurt asking them if you can anyway though.
By that I meant where the original pulls went after they were removed, heh.
Ah okay. Odd that it has no message though (honestly kinda undermines the point of a voice system).
Ah alright, thought so.
Oh? Huh, how about that…
Alright, sounds good. I’m not sure I could give you a number, but in general they’re definitely quite rare.
Ah, i have no idea since they were removed in the 90s. likely thrown away by the techs.
Alright, thanks for letting me know!
Don’t really like telling everyone this, but next time i see a tech, i’ll let him know they left exactly one 1251 still installed that has skipped inspection for 30 years. Maybe i can keep it 
I actually took photos of the day that they took the simplex devices out.
