AG-GDC-150 Flammable Gas Detectors

Fixed Hydrogen Detector

Catalytic bead hydrogen detection for battery rooms and electrolyser areas

4–20 mA Modbus RTU

Hydrogen is the lightest gas — mount at the highest point of the room and in every roof pocket
Standby batteries vent hydrogen on charge; detection is normally interlocked to the room ventilation
Two field-adjustable alarm stages drive ventilation boost and charger shutdown independently
Catalytic sensors require scheduled bump testing and calibration to remain reliable
