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.
The SPC-24 detector can provide vital fire detection in applications where other types of detectors may not be able to respond quickly, or at all, to a fire condition. Examples of some applications where projected beam smoke detectors have been successfully used include:
Atriums gymnasiums theaters museums factories tunnels churches stables warehouses anechoic chambers high air velocity areas
The SPC-24 detector may also be used in conjunction with more traditional spot type smoke detection devices to provide an even more comprehensive detection system.
