HD802EX Explosion Proof Heat Detector

AS-HD802EX explosion-proof heat detector is a conventional type detector with relay output, it’s compatible with most of fire alarm control panels in the market.

The temperature sensing part of the detector uses the sensitivity of the temperature-sensitive element to detect the ambient temperature, it’s particularly suitable for places where there is a severe temperature rise in the event of a fire.
AS-HD802EX explosion-proof heat detector adopts a unique design to prevent insects, dust and external light. With novel structure, reliable performance and strong moisture resistance.
AS-HD802EX explosion-proof heat 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 alarm temperature reaches the preset threshold, the detector indicator lights on, NO contact closed, NC contact opened, 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-HD802EX explosion proof heat detector is applicable to Zone 1 and Zone 2 of areas with explosion-proof requirement in petroleum and chemical industries.
