Of course. Mainly driven by heats and/or manual pull stations.
Smoke detectors didn’t really become popular until the 1960’s/70’s, but I think Pyrotronics is one of the first credited with inventing the ion detector and mass producing it as early as the 40’s/50’s.
(sorry for the multiple posts, I couldn’t edit the one above)
The panel was monitoring a couple of sprinkler system on site and two pull stations. The only notification connected up was a 120v bell and buzzer that rang on the outside of the building.
Non-coded stations have existed from the beginning and were just as common, if not more, than coded stations in pre-1960’s systems.
Those are actually two 4208’s installed side-by-side in that pic.
I think I remember seeing that the System 3 came out in 1967. There have been a couple of control board overhauls and new modules introduced since then.
They aren’t two standalone panels - it’s one system with two cabinets. 4208’s were all custom ordered and built at the factory, so every system was specific for the application. In this case, the system was large enough to extend over two cabinets.
Really? I didn’t know all the alarms in the world were photographed and posted on The Fire Panel!
Sarcasm aside, just because it doesn’t show up on the forum doesn’t mean it is non-existent everywhere else. There could be thousands more of those “rare” pull stations somewhere in the world, but no one where has observed them yet.
