Yeah, I saw the owners manual and it said they make a loud piezo when triggered

From what I can tell tall âwiffle-ballâ detectors like that one are photoelectric; short ones are ionization (donât quote me on this though, thatâs just what Iâve observed with the ones I have).

The one alarm I have in my collection is a First Alert CO400 Carbon Monoxide alarm. Itâs not even a smoke or fire alarm!
I see those in big hotels with an EST Genesis white speaker on the same wall.
I find it interesting that hotel rooms also typically have one of those clapped First Alert Smoke/CO detectors (Yes that one that can say âDetector error in [room name] please see manualâ) even though they arenât wired up to the fire alarm system (As far as I know unless if you can get a househole smoke detector up to a panel) however this hotel in perticular (Hyatt Regency Seattle, the one that hosts Anthro Northwest) doesnât have any pu!l stations.

Accessory relay? Thatâs highly unlikely though. Itâs not intended to set off the fire alarm system
They do have it in the hallways too. The Great Wolf Lodge in Centralia/Grand Mound has the same system with those detectors in the rooms.
Pyrotronics made a flush mount smoke detector too. I have one, just need to take a photo to upload.
There is a old video of that system going off
Is that the same one that the original WTC towers had? (which I think is a DI-2, even though the DI-2âs head sticks out some from the base according to photos Iâve found)
DI 3/5. made in Switzerland. 220 volt DC
I donât think it looks that weird
I think it looks a little weird
Nevermind that!
I have never seen those before
