GST Optical Beam Smoke Reflective Beam Detector with Relay Output

General Descriptions

Conventional Reflective Beam Detector (hereinafter called the detector) is a non-addressable reflective infrared beam smoke detector is   applicable   to   historical   buildings, warehouses,  large  storages,  shopping  malls,  leisure  centers,  exhibition  halls,  hotel lobbies, printing houses, clothing factories, museums and prisons etc, as well as places where slight smoke particles exist.

 

Features

(1)   Wide operating voltage range, big monitoring areas.

(2)   Combination of the emitting and receiving part makes mounting easy and optical pathway accurate.

(3)   Built-in microprocessor enables intelligent judgment of fire alarm and fault.

(4)   The detector can calibrate automatically, which ensures that one person complete adjustment in short time. Its also convenient to operate.

(5)   Self-diagnosis function can monitor the inner fault.

(6)   Automatic  compensation  for  factors  weakening  received  signals,  such  as  dust contamination, positional excursion and ageing transmitter.

(7)   It has passive output contacts for fire alarm and fault.

(8)   Two sensitivity levels can be set in field.

(9)   The detectors optical pathway is designed with strong anti-interference ability.

(*0) SMT processing technology.

(*1) Attractive and decent appearance.
