located on the front cover. 

2. GAS SOLENOID VALVE OUTPUT

240VAC electrical power supplied from the [VALVE OUT] connector using a 3 core cable can 
be connected to a gas solenoid valve which can shut the gas supply on alarm status. 

Pressure sensors should be screwed to the downstream port of the valve.
