Rare Smoke Detectors


Found this brochure for an alarm that looks like the SS718, but it’s an SS69H, why does this have a different model number?

Anyone, @Steel_City_Alarms?

Hey guys I actually realised I may own a rarer-than-initially-thought Family Gard “FG888D.” It’s a first gen from 85 with the white button and “False Alarm” sensor. But there’s a catch, it also has an LED. The other ones I’ve seen on YouTube do not have LEDs. I remember when I bought it from a flea market about 3 or 4 years ago it came in a smaller box than what others got theirs in, and the box was labeled FG888D and 83R iirc. I threw the box away where it was damaged but it had a white button on the box cover too. It was used tho, but came with Please See Manuel and mounting hardware. When I applied power, the alarm was falsing and the horn almost sounded as if it were dying. So do I just so happen to have an extremely rare 1st gen 83R mislabeled as an FG888D?

I don’t believe so: BRK/First Alert likes to label random alarms “83R” for some reason: heck I have two Family Gard-style units that are both mislabeled 83R (no idea what their actual model numbers could be). I also used to have an LEDless FG888D, but I got rid of it & have not gotten a replacement since (as much as I’d like to have one again): not sure what the story is with some Family Gard-style detectors having LEDs & others not to be honest.

Well the other first gens I’ve seen don’t have an LED, and I’m the only one who owns one with the LED altogether.

Here’s a video of it.


Honeywell TC100C1002-1. As labeled on the inside it runs on 24VDC.

Cool, nice find! I assume it’s meant for use with Honeywell’s commercial FACPs like the FS90, right?

I’d assume it is meant for that

This might be of interest to y’all: An ancient ESL 445CT detector I found at the supermarket I go to (there’s more of these units)

The Honeywell TC100 detector would have been in use prior to the FS-90. I have some still in service connected to Honeywell W-940 and FS-20 panels.

I thought these were residential only detectors.

Well the FS90 is the only panel I know to be compatible with the TC100 as it’s the only panel the TC100 has ever been demonstrated with via that one video by thesdx.

Apparently not: not only did Honeywell make both residential hardwired & battery-operated models, but they also made a commercial 24VDC-powered model too!

Pyrotronics DI-2D with flush mount ring. Just waiting for the backbox/base to arrive because then I’ll have a completed detector (all parts are NIB somehow). These also contain 15μCi of Am-241, so these are quite spicy (although better than the F3/5A with 80μCi, and are known to leak their sources.)

Sonic would approve of this.

Double whammy btw.

The alarm in question is a DSC AMS-220. I personally only seen this one once (the one in the photo) and I think it’s rare.

I have already posted about these in my own posts, but I’m adding them to this thread as I believe they fit.

Simplex 4262-20
Pyrotector 304924C
Simplex 4262-601
Simplex 4262-4
Simplex 4262-5

The difference between the 4262-4 and -5 is their operating voltage. The -4 is 24VDC and the -5 is 120VAC

those smokies look cool!!

That whiffle ball head to the left looks like it’s the colour of one of those old Honeywell thermostats.

It does honestly. I think they were trying to match the color of the base to the head, but the paint they used just wasn’t it. It’s a lot more obviously different in person.
