Gas leak detection system
for heating rooms and similar environments
Electronic control unit for gas leak detection with single sensor aimed to drive a
gas flow cut-off 12VDC normally closed (NC) or normally open (NO) solenoid
valve. Single threshold sensor with tin dioxide sensing element. Possible control
of auxiliary devices (hooters, flashing lights, fans...) or 230VAC solenoid valves
through built-in relay. 24VAC power supply. Built-in battery charger for optional
external 12V buffer battery charge with automatic intervention in case of power
failure.
LYC11 control unit is used, connected to a QA..13/A sensor, for optical/acoustic signaling
or to drive a gas flow cut-off valve in presence of dangerous concentrations of:
• methane (CH4)
• LPG
• carbon monoxide (CO)
note: Only one sensor QA..13/A can be connected to the control unit
