I recently was refurbishing an old building with several others and the old fire system was being pulled out in favour of a new install, I was allowed to assist with that and keep all the old devices. The ripout is still ongoing but I removed this break glass unit, and after a bit of googling I cannot find any information on it. The building in question is a abandoned flight school and the break glass unit is made by Pyrene, who are notable in airliner industry for fire protection. Any information is appriciated.
Holy moly, that’s a heck of a find
Pyrene I believe were an old British company that no longer exists and made heat detectors
Well, I pressed the button and it literally just broke apart. The plastic may be a bit brittle. I’ll probably look at finding a new button for it
