SPC-ET | Hochiki's EN Approved Fire Detection
Optical Beam Smoke Detector | CDX Conventional
SPC-ET is a two-wire beam smoke detector that consists of an emitter and receiver that cover a distance of 5 – 100 m providing maximum coverage of 1500 m2.
When used on a conventional system the emitter and receiver can be powered directly from the zone or if required the emitter also has an option to be powered from a separate 24 V dc supply. The SPC-ET can also be interfaced to Hochiki’s ESP system, the receiver can be connected to a CHQ-SZM Single Zone Module or a CHQ-DZM Dual Zone Module, and the emitter can then be powered directly from the loop or via a separate 24 V dc supply.
The SPC-ET comes complete with a termination module that fits directly onto a standard U.K dual backbox, this allows the detector to be surface or flush-mounted. Line continuity options can be selected on the termination module and these are based on the Schottky or Zener diode method.
