Rare Smoke Detectors

Can anybody identify this detector? There’s a red LED that’s constant on and a test button. I’ve never heard the one in my apartment go off, but I’ve heard that they can be activated without triggering the building’s system.

These are in my apartment on a college campus. If it helps anything, the building has a Simplex 4005 system, with each individual building being tied into a 4100 (pretty certain) and a Simplex annunciator at the office. In quite a few of these apartments, they’ve been replaced by Gentex photoelectric smokes.

BRK 5919TH. Photoelectric+Heat. Pretty rare indeed.

Thanks. The hallways have old model TrueAlarms and the laundry room has a TrueAlarm heat detector, but didn’t know what the heck these things were. Out of curiosity, could these detectors activate the Simplex 4005 panel?

This complex has a bunch of strange things. Original horns in the apartment buildings were first generation TrueAlerts (some lacking the “TrueAlert” label), but the office building had SpectrAlert classics with 1st gen TrueAlert strobes in the restrooms. Most of the apartment horns have been replaced with SpectrAlert Advances (horn only in the apartments themselves, h/s in the hallways) with a few Genesis and GX-90 horns scattered around for good measure. My apartment has an original TrueAlert horn, but I don’t know if it even works and I assume its days are numbered.
