GAMMA 654/656 Gas leak control unit and remote detector with optical-acoustic alarm and relay

Remote detector for methane and LPG to be connected to the GAMMA 656 control unit. It signals the presence of gas in the environment via optical and acoustic alarms and sends a signal to the GAMMA 654 control unit, which shuts off the gas solenoid valve.

When the gas concentration exceeds 10% of the LEL (Lower Explosive Limit), the detector automatically activates a red LED (ALARM), an acoustic buzzer, and a relay to control auxiliary devices (e.g., normally closed solenoid valve). Once normal conditions are restored, the alarm resets automatically. To fully restore operation, the connected safety solenoid valve must be manually reset.
