What alarm do you have at work/school

Oh yeah: was going to comment about that but forgot. Really? Residential smoke (or possibly CO) detectors in a commercial building? What the heck?

Yep, I have the same in my apartment. Not sure what they’re doing there.

They could be the carbon monoxide version of the family guard fg200

Yeah, that’s what I was kinda thinking too (even if there are system-connectable ones actually meant for commercial applications like System Sensor’s CO1224-series).

That’s exactly what they are. If you look closely, there is some text on the alarm that you can barely see that identifies it as a CO alarm. I’ve never seen these outside of an RV, where they are pretty much the standard in almost every model.

Here’s what it is: It’s a First Alert/BRK CO250.

I found out that around a year ago my former elementary school got portables. I expected them to have the spectralert classics like the rest of the building, but upon finding a photo on the school’s page, they apparently have L-Series alarms in them. Here’s a cropped photo.

I can definitely see those being CO2 detectors. Though I’ve been in commercial buildings that don’t have fire alarms, but rather just smoke alarms.

“CO”: “CO2” is carbon dioxide, heh.

I don’t believe I’ve seen many commercial buildings with residential smoke detectors, but when it comes to those that do have such I don’t know what the owner or staff are thinking: they are not suited (or likely rated either) for commercial applications: that’s what a commercial fire detection & alarm system is for! (as evidenced by the “commercial” in it)

Most of the time you’ll see residential style detectors outside of elevators in commercial settings. There’s a relatively new school near me that’s like that.

What? I don’t know why that would be the case: for one thing most detectors mounted in such spots have a relay but no sounder since they’re often used for elevator recall, & most commercial detectors with sounder bases are used in places like hotel rooms instead.

These Gentex units (without the heat sensor though) are what I see the most and are what that school has.

Funnily enough I’ve very rarely seen those detectors in actual installations: most places just go with sounderless detectors made by a company like System Sensor instead.

Here in Michigan might be different. A lot of places just have commercial detectors outside elevators, but most seem to have residential style. I think even my local hospital uses them too.

My School had a Simplex System that began my love for the hobby!
Initiating Devices: 4251-20s and 4251-30s
Strobe Plates: 4903-9101s and 2903-9102s
Horns: 2901-9806s, 2901-9838s, and 2901-9840s

I have various alarms at school, but here’s one of them:

This one is everywhere including outside (this one is brown while the others are red)^^

I’m new here so hopefully this one is good and idk if it’s okay to post the rest of the system (there’s one other alarm and 2 different pull stations)

Neat! Even if whoever painted that 7002T clearly didn’t get the memo on not painting fire alarm/life safety devices, they did make quite the unique device in the process! (you oughta try & save it if it’s ever replaced!)

Yeah, should be fine I think: if anything that’s kind of the point of this topic: to document various workplace & school systems as much as possible.

Welcome to the forums! That is an awesome device, they are mechanical, so they will get raspy over time, since they are most likely on continuous. If they paint a device, they will get damaged overtime, most likely already.

My school has Simplex 2099-9756’s under stopper II without horn. Alarms are Simplex’s 4903-9237’s and some are under a cage guard. New gym is a voice evacuation along with cafeteria, the cafeteria has 4904-9136’s, a 4903-9425, and a 4903-9127. The new gym is the regular speakers and 4099-9003’s and panel is a 4010Es.

More-or-less: some hold up better than others.

Not necessarily, even though that is why you’re not supposed to paint them.

Some do hold up!

Yeah, they don’t let you paint them. Overtime the paint will dry up and little pieces of it goes into the alarm damaging the alarm.
