Yeah scoreboards use the same type of AC powered horns (not theese particular ones) like the Federal Signal Vibratone 350 or the Wheelock 31T-115

Oooh, a Faraday system from the 80s! A few buildings at my college campus have the newer version of those Faraday F1GT "Chevron" pulls; two buildings that share a Faraday MPC-7000 have the addressable versions with dual-action adapter covers on them (the alarms are Space Age VA4 horn/strobes.) My college started out with Standard Electric Time in the early 70s, then Simplex in the late 70s, switching to Faraday around the late 80s and sticking with them until early this decade when they switched to Notifier (along with a Fire-Lite system, but still Honeywell.(

Yeah it's an old system there is not panel in place and the alarms are all rated for 120vac in the building so it has its own ac breaker so it will turn on instantly when pulls and turn off immediately when reset

[@Fahrenheit4051]

This system has no panel, but some panels activate instantly as well - like the old Fire-Lite Miniscan series, and the Simplex 4207 and 2001.

[@weatherdan882002]

You're right!

[@user-ro7vf8jc6x]

I had these alarms in my elementary school when I was in 2nd and 3rd grade.

[@Skyhawk1998]

Do you see systems like this very often? It strikes me as strange to do this sort of setup on this large of a system with that age of equipment (I'm guessing 1980s). Unless this was a retrofit of some kind, which still seems odd that they'd leave such an obsolete setup in place. How do those smokes work? Relays?

[@MisterBroadnax]

I’m probably not right, but this is my theory for how this system works. I believe the Initiating Devices (Smokes & Pulls) are wired in Parallel. With all of the positive leads wired together and all of the negative leads wired together. Each device would have 4 wires going to it except for the last device on the loop. All of those 7004t Horns are wired in parallel (so that each device gets the same voltage and amperage) along with Inverting Realys (NOT Gates) to drop power from the door holders (These relays are potentially built in to each door holder). As soon as a pull station is pulled (or a smoke detector is tripped), it shunts its terminals, completes the circuit, and makes the horns sound. No need for EoL Resistors here, there is no supervision... I also think that this would be a challenging system to add a proper panel to as those 7004t horns use AC voltage and not DC voltage.

[@safetech]

Standard normally open relays. Smokes are 4-wire.

@@lawrencem.tecson3222 1 still works no junk

[@TheCarson116]

Huh, very unusual having the alarms wired directly into the building's power. Also for anyone wondering, the smoke detectors are indeed made by Gentex, you can also find them labeled Masterguard. (Masterguard is another brand name that Gentex uses to sell smoke, heat and CO detectors under) As far as how they activate the alarms, these particular detectors have internal Form C relays, which are most likely hooked to the same wiring that all the pull stations are, when the detector activates it activates its internal relay as well, which sounds the alarms. Kinda odd though how they first latch, (as evidenced by the LED illuminating steadily upon alarm unlike non-latching detectors where the LED pulses rapidly instead) and then they self-reset despite there being no panel to reset them. Even stranger is that they're the models with built-in horns when the building itself has separate fire alarm horn/strobes and thus the smoke detectors shouldn't require sounders as well. Very rare Faraday horn/strobes I see as well, the horns were rebranded by Simplex as the 2901-9833, albeit 24VDC instead of the 120VAC versions seen here. In fact, a number of both Simplex and Federal Signal horns were made by Faraday and then rebranded by those companies. Gotta agree with quite a few people in the comments, kinda surprised a system both this old and this not-up-to-code hasn't been replaced by now. (would definitely take quite a bit of rewiring since all the alarms are hooked directly to the initiating devices) I do see a Wheelock 7004T most likely replacing one of the older Faraday alarms, but that's about it. I'm guessing the smoke detectors are also not the originals. (one of them is so old apparently that it's turned yellow!)

First off, this system was put in before NFPA mandated panels and system installations. Second, the system is a non latching system. Which means that the system doesn't stay in alarm once a device is tripped or activated. There's no panel that tells which device has activated plus it doesn't keep the alarms going once a device is activated and reset.
