Alarm Points


Every alarm in the GMA can be individually adjusted. False alarms are eliminated with the adjustable alarm delay. The point values can be freely adjusted within the detection range. They can also be adjusted later with the control keys to adapt to changing requirements. Every point value can be selected to be latching / non-latching or resettable / non-resettable.

Alarm Relays

Every controller provides four voltage-free relays for the three alarms and the fault warning. The relays may be used to control external alarm devices like lights or horns. They can even introduce specific counter measures to prevent or limit dangers from gases or vapors.

Easy Calibration

Zero point adjustments and calibrations are done through menus on the GMA controller.

Additional Features

The GMA 41B store minimum or peak values, depending on the type of gas being detected.
The GMA (variant B) offers an integrated BUS-system. The BUS-system supplies power from one source to all connected GMAs. The BUS-system also connects individual controller alarms together so that, with the use of the keyoperated switch, all connected monitors have one collective alarm. Several GMAs can be connected easily without additional wiring.
