The Merlin 1500S ventilation interlock system is specifically designed for use in commercial kitchens to meet BS6173. This panel is designed for use when the kitchen appliances do have flame failure devices fitted, therefore gas proving is a not a requirement.
The Merlin 1500S System acts as an interlock between the ventilation system and the gas solenoid valve. The systems can work in conjunction with both current monitors and air pressure differential switches in order to interlock with up to 4 fans.
