The Merlin CT1250 ventilation interlock system, with built in current monitoring, is designed specifically for use in commercial kitchens to meet BS6173: 2001, which is now a much-recognised standard in the catering industry.
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 a built in power monitor which is a method used for interlocking a kitchens gas supply with the ventilation system. As an alternative to pressure differential switches the CT1250 is designed to monitor the electrical current going to a ventilation fan.

When the fan is turned “on” the CT1250 monitors the electrical current going to the fan motor, when there is sufficient current going to the fan motor our panel receives a signal to indicate the fans are operating. Turning the key to the “on” position 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 on the Merlin CT1250 panel fascia will flash. This informs the electrician or kitchen staff which fan has failed.

Operating the system in the above manner will ensure the requirements of BS6173: 2001 are fully met where all the catering equipment has flame failure devices fitted.

! A Gas Safe installer would be required to fit the gas solenoid valve. Check the register at
