For Sale: This is a commercial Pyr-A-Larm fire and smoke detector designed for installation directly into heating,ventilation, and air conditioning duct systems.
Manual has some wear, see photos. The bags of accessories including the reset key are all factory sealed. The photos and diagrams in the manual show a small cylinder that is not included with this set- I think it's a replaceable sensor module that you had to purchase separately. It MAY be PYROTRONICS model DI-4A sensor and it looks like you would just insert it into the holder and twist to lock in place. The terminals seem to match up with photos of that module but make sure to do your own research about what sensor you will need to use with this model.
Don't know much about it except it's definitely never been installed or used. I think it was probably manufactured in the 1980's but just a guess. It appears as if Pyrotronics is a Siemens company.
