Product Description

JDHW (reflective) explosion-proof infrared beam smoke fire detector (detector) is a non-coding type radio-infrared beam smoke detector, suitable for installation in the explosive gas environment with ii-B-class T6 temperature group, for the initial stage of the fire smoke occurred in large areas, high racks, long distances and other places of fire detection. This product can be and any domestic and foreign manufacturers of fire alarm controller supporting the use, in line with the REQUIREMENTs of GB3836 series standards, through the national designated testing institutions, and achieved explosion-proof certificate.
The detector must be used in conjunction with the reflector. The detector automatically completes the commissioning of the system and the determination of compensation, fire alarm and fault for changes in external environmental parameters, and gives status indication through indicators and signal output terminals, which are output as passive contacts. The most important feature of the detector is that the transmit and receive parts are combined, making commissioning particularly convenient, and only one-sided wiring (no wiring on the side of the reflective plate), reducing installation costs.
