The gas failure detector HG-GMM controls up to 10 contact gauges (switch Ex), whose switches are closed under normal conditions.
If a contact opens or more than one contact opens because of a gas deficit, the gas failure detector registers this with an acoustic and optical signal.
Simultaneously, the switch logic also registers if there is a break in the cable or an interruption of the electricity supply.
