SPC-24 | Hochiki's UL Approved Fire Detection

Projected Beam Smoke Detector | UL Conventional Fire Detection

SPC-24 Description 

The Hochiki SPC-24 Projected Beam Smoke Detector consists of an emitter and receiver. The SPC-24 detector should be placed so that smoke generated by a fire will likely rise into the path of the beam.

The receiver is constantly monitoring and measuring the intensity of the beam transmitted by the emitter. Should the smoke from a fire cause a decrease in the signal strength of a magnitude that exceeds the programmed obscuration setting, an alarm signal is generated.
