I guess the building originally had a Simplex 2001 system of some sort, then they replaced the panel. Neat to see older Simplex devices on a 4005 system
@whelenvortexr4 Yep, they can. They sort of did something similar at the school I attended for kindergarten, except the old panel is still intact and used for the pull stations and heat sensors (Simplex 4208), and they have a newer Simplex FACP (either a 4005 or 4010) for duct detectors and most likely to drive the signals (4051+4050-80 horn/lights)
@whelenvortexr4 They also just did the same thing at the local YMCA Youth Center; they swapped out the building's old Simplex 2001 fire alarm panel with a new Simplex 4006 system (retrofitted right into the 2001 cabinet!) but the existing signals, pull stations and heat detectors remained intact
@wileyk209zback The one I went to had Tru Alert and some other Horn Strobe, Wheelock MTs, and some Simplex Detector, with Quick Connect Detectors, and Tbars.
when i first played this video it gave me goosebumps everytime i hear any fire alarms going off. i dont know why but i used to be afraid of them when i was in kindergarten. i actually hid in the closet and they had to hire a fireman to get me out lol.
@weatherdan882002 I was curious of that myself. If those horn/strobes in the middle of the corridors were added after the original devices, they could be on a dedicated signal circuit. Some of the ADA apartments had strobes, so that's probably the case. I don't think the new horn/strobes were replacing failed devices because you'd probably see a retrofit plate there. I took this video like a year and a half ago when I was still at Simplex.
@SimplexGrinnellTech My best guess is there is a visual signal circuit coded to fast march, and an audible signal circuit coded to slow march for the horns.
@blackmaxima After watching the video a little more, I saw the lights are on 120bpm. Interesting. Are the strobes on the same signal circuit as the lights?
@SimplexGrinnellTech well..... I wouldn't put it past an installer or tech to wire a strobe circuit, which requires steady non-pulsed power, to a coded circuit for the lights. Seen it quite a few times before that, but usually when I've seen that, the strobes flash at the same rate it's being coded, so here they'd probably flash to a fast march pattern and skip a few times.
@SimplexGrinnellTech I've seen some of the installers/techs connect smartsync devices to coded signal circuits. the strobes will flash to the temporal coding. I used to note it all the time but nobody in the office took it seriously. so whatever.
Why dose it sound like it's underwater.

Interesting system... horn/lights and horn/strobes. Was it originally installed like this or did they add the horn/strobes after?

I'm glad those fire alarms aren't where I live in England

@wileyk209zback Our school has a Siemens MXL-IQ FACP and I bet if they ever built on they would replace it with an MXL

@blackmaxima nice. The fire alarms in our condo building are now required to be tested every 6 months

?: do the strobed signals have their own non-coded NAC or are they hooked up to the same NAC that flashes the incandescant lights?

How were the visual signals on some of the light plates getting a 60bpm flash rate?
