Fire alarm systems explosion heat sensor
Explosion heat Detector Specification:
1. Introduction:
The explosion-proof performance of the explosion proof heat detector AW-DFWT is in line with the requirement of GB3836-2000 series of standards and inspection designated by the National Inspection Unit, made explosion-proof certificate. The explosion proof heat detector suitable for 1 Zone and 2 Zones contains a Class II Class A, Class B, Class C,T1 to T6 temperature class in dangerous places for explosive gas atmospheres.
The explosion proof heat detector AW-DFWT is non-coding switch type (relay output) detector, and supporting the use of any of the domestic and foreign manufacturers of fire alarm control.
The explosion proof heat detector uses of thermal components to detect the temperature sensitivity of the ambient temperature;it has a built-in micro-controller, to curing high reliability fire judging program,using a special process for processing.It is very stable and reliable, especially for severe temperature rise in the event of a fire place.
