Explosion Proof Smoke Detector

The Explosion Proof Smoke Detector has Division and Zone explosion-proof ratings and is suitable for industrial and commercial applications.The detector is designed to operate effectively with smoldering and rapidly growing fires. The detector outputs include a localized LED and a fire relay.The detector is suitable for explosive gas explosive atmoshprere and explosive dust atmosphere.
Typical applications that use the detector include:
– Combustible storage facilities
– Munitions manufacturing
– Volatile chemical storage
– Chemical processing plants
– Petroleum refineries
– Turbine enclosures
– Battery rooms
– HVAC applications
