Merlin CT1200S Gas Interlock Control Panel is for use where equipment has no flame failure devices.
To operate the panel the fans should be turned to the “on” position, once our panel receives a signal to indicate the fans are operating turn the key to the “on” position this will open the gas solenoid valve. If the fans should fail, the “fan fault” LED on the panel will illuminate and the gas solenoid valve will close. When there is a “fan fault” the supply fan or extract fan led will flash to inform the electrician or kitchen staff which fan has failed.
Operating the system in the above manner will ensure the requirements of BS6173: 2001.
