Rotork plc Ventilation and Interlock Systems

Gas Ventilation The Alcon GSS1 ventilation interlock system 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 system acts as an interlock between the ventilation system and the gas solenoid valve. It ensures the Alcon EN161 approved gas solenoid valve cannot be opened until the ventilation system is proven to be operating. The fans are monitored with air pressure differential switches. Gas Interlock System The Alcon GSS2 gas interlock system 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 GSS2 is designed to monitor the electrical current going to a ventilation fan. When the fan is turned“on” the GSS2 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.
