All things smoke detector

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

From what I can tell tall “wiffle-ball” detectors like that one are photoelectric; short ones are ionization (don’t quote me on this though, that’s just what I’ve observed with the ones I have).

Well according to EST they can

Your are referring to the 2424ait

The one alarm I have in my collection is a First Alert CO400 Carbon Monoxide alarm. It’s 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 “Detector error in [room name] please see manual”) even though they aren’t 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) doesn’t have any pu!l stations.

Accessory relay? That’s highly unlikely though. It’s not intended to set off the fire alarm system

Normally on a est system, you would see these in the rooms

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.

Caleb_Culwell · May 10, 2023, 4:25pm

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-2’s head sticks out some from the base according to photos I’ve found)
