Smoke/Heat Detector Collection

Here’s a picture of my various smoke and heat detectors that I have been collecting. These include a mix of conventional and addressable detectors, with varying degrees of detection principles and thresholds.

That’s really cool, I am jealous of all the Notifier devices. Do you have a list of all the model numbers?

The 4 identical detectors on the right are all Pyrotronics DI-4s on DB-4 bases.

The Pyrotronics DI-4s are quite neat. We don’t hear about those detectors very often. I’m particularly fond of their design, as I find that it still looks fresh today (it reminds me of System Sensor’s current line of addressable detectors); it certainly stands out among other smoke detectors from the ‘70s and ‘80s.

Yeah, the DI-4s are pretty interesting for some older detectors. They have adjustable sensitivity levels via a dial on the head; find that pretty neat. These work pretty well based on my tests too. These should complement my System 3 demo setup nicely!
