What rare smoke alarms do you have in your collection, here is mine
Four wire Model 449CT ESL Sentrol manufactured in 1994 week 48.
Wow , where did you get it
I’m a property inspector. I immediately saw a bunch of detectors of the same age, immediately tested, and discovered that the central alarm had been disconnected years before.The detector itself was a high end commercial model, with a field cleanable smoke chamber, photoelectric. The device is technically a detector, not an alarm, because there is no local buzzer.
The detector itself worked fine, the central monitoring system not so much:
Wow , did you take the detector
The only VINTAGE smoke alarm I have is a Sears one and one of the old Wind up Smoke Bells. I don’t really collect smoke alarms anymore but if they’re vintage or are rare i’ll grab them.
