GS920 Household Gas Detector with seismic feature type A
Cod. GS920 - Household Gas Detector with seismic feature type A
The GS920, thanks to its seismic detection feature and the possibility of selecting the intrinsic safety control, is a leadingedge technological device. Together with its catalytic sensor technology, it detects the presence of explosive gas, such as: Methane and LPG, with trip threshold calibrated at 10% of Lower Explosion Limit. Using the built-in relay it can activate: solenoid valves, sirens, and any other alarm signal device.
The power supply assembly allows operation without the need of a backup battery, a manual reset solenoid valve with a 12Vdc coi l .
However, if the voltage absorption is too high, you can connect a suitable backup battery, which is recharged automatically.
The seismic control allows closure of the solenoid valve, stopping the gas original source.
