SD801EX Explosion Proof Smoke Detector
AS-SD801EX explosion-proof smoke detector is a conventional type detector with relay output, it’s compatible with most of fire alarm control panels in the market.
AS-SD801EX explosion-proof smoke detector adopts new scattering technology and imported optoelectronic devices to improve the reliability, stability and consistency of the sensor, and adopts a unique labyrinth design to prevent insects, dust and external light. With novel structure, reliable performance and strong moisture resistance.
AS-SD801EX explosion-proof smoke detector has been fitted with a safety barrier. The safety barrier adopts a resistive and transistor dual electronic switch circuit, which has fast starting speed and can be automatically restored.
When the smoke concentration reaches th preset threshold, the detector indicator lights on, the fire alarm signal will be sent to the main control panel. The detector will be restored only when the system is reset (or power off and then power on).
AS-SD801EX explosion-proof smoke detector is applicable to Zone 1 and Zone 2 of areas with explosion-proof requirement in petroleum and chemical industries.
