Optical-electronic smoke detector for early detection of fires with a low concentration of smoke.
Rubezh IP 212-187 optical-electronic smoke detector — a threshold device for early detection of smoke in premises, connected via a two-wire loop to a control panel. An optical indicator on the housing allows visual monitoring of the detector's status during facility rounds without accessing the central panel. High sensitivity to low smoke concentration ensures a response at the early stage of a fire, when evacuation is still safe.
