    Explosion-proof infrared beam smoke detector JDHW-1.

    Product Description

    JDHW (to-shot) explosion-proof infrared beam smoke-sensitive fire detector (detector) is a line smoke-sensitive fire detector, suitable for installation at both ends of the protective space, a certain concentration of smoke alarm. This product can be used in places where smoke appears before the formation of a fire, especially suitable for large spaces, high racks, long-distance places. More responsive to black smoke. 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 consists of a pair of transmitters and receivers. The infrared beam emitted by the transmitter passes through the protective space, reaches the receiver, and the smoke from the combustion of the material diffuses to the beam area, so that the radiation flux received by the receiver weakens, and when the radiation flux weakens to a predetermined smoke-sensitive action threshold, the receiver outputs fire alarm information to the fire alarm controller. The detector receiver is equipped with six indicators indicating the strength of the signal for engineering commissioning.
