Gas Alarm Controller

Gas Alarm Controller Shield 8001AB Series

Product Overview

SD8001A/SD8001B series gas alarm controllers (hereinafter referred to as controllers) and gas detectors form a gas safety detection system to realize centralized monitoring of gas detection and alarm. Gas detectors are installed in indoor and outdoor hazardous areas where gas leakage is possible; controllers are installed in non-explosion-proof areas (control rooms).

Application

This leak detector is widely used in the petroleum, chemical, environmental protection, metallurgy, refining, gas distribution, biochemical medicine, and agriculture industries.

Indicator Status Description

Indicator Name		Color	Functionality
System	Master alarm	Red (color)	This indicator is always on when an alarm exists on the controller.
Status	Systems	Greener	During normal operation, this indicator flashes (1HZ, lit for 0.5s)
	Total failure	Yellow (color)	This indicator is always on when there is a fault in the controller.
	Anechoic	Greener	This indicator lights up when the controller performs the "Silencing" function during a system fault or alarm condition.
Mains normal		Greener	This indicator is always on when the main power supply of the controller is normal.
Main power failure (of an electrical system)		Yellow (color)	When the AC220V power supply is disconnected or the host power supply voltage is too low, this indicator light is always on.
Normal power reserve		Greener	This indicator is always on when the controller backup power is normal.
Backup power failure		Gellow (color)	This indicator is always on when the controller backup power supply is disconnected, short-circuited, or when the voltage is too low.
Linkage 1		Greener	This indicator is always on when the 1st relay is activated.
Linkage 2		Greener	This indicator is always on when the 2nd relay is activated.
