The Merlin CT1250 ventilation interlock system, with built in current monitoring, is designed specifically for use in commercial kitchens to meet BS6173. This panel is to be used when the kitchen appliances do have flame failure devices, therefore Gas proving is not a requirement.
The Merlin CT1250 acts as an interlock between the ventilation system and the gas solenoid valve. The system has built in current monitors in order to interlock with up to 2 fans and offers an alternative to using air pressure differential switches.

Merlin CT1250 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.
