Smoke alarms go off in my condo complex

[Simplex 2903-9101]

Well, we had a bit of a false alarm last night. Listening to all the different pitches and cadences of these hardwired smoke detectors was fun for the first few minutes, but it quickly got annoying.




The fire department ended up coming, and it took almost an hour to silence them. Fortunately, there was no fire. One of the detectors was putting out a low battery warning, and I wonder if that somehow triggered it.

So your condo doesn't have actual alarms in it and just smoke alarms?

Probably a smoke alarm/pull station system. I just serviced one in a renovated walkup building, they literally have combo smoke/strobe alarms everywhere, which are all interconnected together. Plus they had 2 pull stations on each exit, All controlled by a breaker on the electrical panel. It's a really cheap fire alarm system, but also legal depending on the building and occupant size.

This is the first time I have heard of a system ANYWHERE having pull stations with just smoke alarms.

Sorry for the late response, guys. It's just 120VAC interconnected smokes with backup batteries. The system is in the basement only - the condo units have standalone smoke alarms.

I've never seen a system with just smokes and pulls. Never knew they existed. How do the pulls trip the smoke alarms?

BRK makes a interconnect module, so you can connect devices like pull stations or heat detectors up:
