Gas Warning Systems

Gas warning systems protect lives and health by monitoring the atmosphere inside any enclosed space and triggering an optical and acoustic alarm, as soon as the concentration of the gas that is being monitored exceeds the preset threshold level.

AMS gas warning systems are based on semiconductor sensors that have proved themselves over the years.

AMS gas warning systems:
Type P, for monitoring liquid gas (Propane/Butane) and natural gas (Methane)
Type C, for monitoring carbon monoxide (CO) and smoke (fire)

Series camp signal and camp signal S/2


Camp Signal
ø 55 mm,
Height 30 mm

Camp Signal S/2
ø 58 mm,
Height 40 mm


The series camp signal model is a self-sufficient warning system that incorporates the sensor and the acoustic signaling unit in addition to the semiconductor based electronics.
It is designed to work with a 12 DC current supply.

The series camp signal S/2 model is equipped with an additional switching relay (1 A, 2-way electronic switch) which can trigger any connected device in case of an alarm, e.g. disabling any gas supply by triggering a magnetic valve or turning on an external siren or flashlight.
