Merlin 2000S Gas Interlock & Gas Proving

The Merlin 2000S ventilation interlock system is designed for kitchens where gas pressure proving is required. OGS Merlin 2000S acts as an interlock between the ventilation system and the gas solenoid valve. It ensures the gas solenoid cannot be opened unless the ventilation system is proven to be working and working at such a speed that is effective to exhaust the fumes from the appliances.

The fans can be monitored through air pressure switches or by means of an additional current monitor. To operate the Merlin 2000S the fans should be turned to the ‘on’ position, once the panel receives a signal to indicate the fans are operating the key on the panel can be turned to the ‘on’ position and then the system will perform a gas proving test. If the fans should fail, the ‘fan fail’ LED on the panel will illuminate and the gas solenoid will close. Additional sensors and safety shut off buttons can be wired into the panel and there is a 12 vdc output for external alarms.
