GMA 41
GMA 44
GMA 41/44 SWThe GMA 41 one-channel controller and the GMA 44 4-channel controller are an integral part of safe and reliable gas warning systems.
Every alarm can be adjusted separately. 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.
Additional
features
The GMA 41 and GMA 44 store minimum or peak values, depending
on the type of gas being detected. Even immediately following an
alarm, gas dangers can be accurately 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 key-operated switch, all connected monitors have one collective alarm.
Several GMAs can be connected easily without additional wiring.
