Can Anyone Help Identify This Smoke Alarm/Heat Detector?

09/26/2017 12:04 PM

Hi all, just wondering whether anyone would be able to identify whether this is a smoke alarm or a heat detector? Or at the very least, would anyone have any idea of what brand/model it may be?

There are absolutely no labels or indicators on it and I'd like to know what it is if possible without triggering it.

Thanks

Unscrew it and look on the back. That will not trigger it.

Not sure where your located, but if you have low humidity you can destroy the smoke detector by static electricity. You may not feel the shock, but if it's connected to a central fire annoncator panel you'll know it!

I had the fire department show up 4 different times while changing out smoke detectors in a 12 story hotel before I found out what killing them. And you plan replacing that detector, dispose of properly, it contains a radioactive isotop.

Maybe it is one of the newer smoke detectors, that relies on optical detection of smoke.

I am unsure of my answer, so it is merely a hunch in the dark.

It could be a surveillance camera....or a listening device....even a speaker perhaps...Is this in your house or a property you maintain?

Looks like a smoke detector to me.

Whatever it is you must be able to replace the battery so removing the cover will not trigger it and might reveal more information.

You are assuming that it is battery operated. Some are hard-wired.

In fact, the one shown in post #7's link specifies 24-36V source; that tells me it is intended to be hard wired.

If it is optical, then it would probably be a smoke detector. A heat detector has no reason to be anywhere near that large.

no he is not assuming it is battery operated. in fact it is most likely hard-wired but a battery back-up is installed if the power goes out it can still work.

No visible marking of any type?

And this is (supposedly) a component of a UL listed fire detection/annunciation scheme? This strikes me as quite odd.

Are you certain it isn't a housing for a spy camera?

What is the 4040? Doesn't appear to be a manufacturer sticker. Is this a room number?

It may be a combination smoke (optical) and heat (thermal)

The large flat surface is indicative of a heat detector with a thermal switch.

Heat detectors are normally used in attics, utility rooms and kitchens. These may or may not be integrated with a smoke detector based on numerous factors.

Most detectors are one type or the other.

If you have an adressable system meaning there is an annunciator panel showing where and what went off? ... Then twisting and popping off the head will cause a trouble alarm.

Heat detectors are usually identifiable because the have an exposed aluminum disc, but for visual reasons this may have changed.

Yes, I agree with most of what is being said here, but I will add:

"cold smoke will kill an infant just as fast as hotter smoke".

I checked google to see if that claim could be substantiated, none located, other than cold smoking or hot smoking.

I am saying that smoke all by itself will migrate past open doors into the baby's room, and settle down and stifle the life out of the innocent sleeping child. Heat at that point is irrelevant. That is why the new smoke detectors out there are better by far than the cheap ones at Wally world.

Heat detectors are also widely used in attics, kitchens, utility rooms and garages. There are different thermal ranges that will set them off for different applications, but they will trigger well under 200 degrees and give early warning of out control heat.

They are used to avoid false triggering from appliance use, dust, etc.

Requirements state smoke detectors within X feet of all bedrooms and stairwells etc. Heat detectors would never be used place of smoke near a bedroom.

Is it hard wired or battery powered? It is supervised or not? If supervised, do they service them? If you are wanting to avoid cost from the service company, get ear plugs and the phone number of the supervising company. Then take it off the ceiling; if it alarms, phone the supervising company immediately and tell them it is a false alarm and that you are working on the system--or phone them ahead of time if you know it is supervised. More info should be on the back.
