The detector complies with the requirements of TU 26.30.50-208-81888935-2017 and is designed to detect combustion products (smoke) in fire protection systems of explosive objects and generate “Fire” and “Fault” signals.
The detector according to the principle of operation is a smoke threshold linear optoelectronic. To control a possible smoke zone, an infrared beam is used between the emitter and the photodetector. It is installed in large rooms with high ceilings. Recommended for use in unheated rooms.
The detectors are designed for operation at an ambient temperature from minus 40°C to plus 55°C, climatic version UHL1 according to GOST 15150-69. Atmospheric pressure from 84 to 106.7 kPa. The degree of protection of the shell is IP67 according to GOST 14254-96.
The detector corresponds to the III class of protection against electric shock according to GOST 2.2.007.0-75. The metal case has protective grounding and working insulation from current-carrying parts.
The design of the detector ensures its fire safety in accordance with GOST R 53325-2012.
The detectors are produced with housings made of stainless steel 12X18H10T and in versions that differ in the presence of an address label (Table 1).
