Gas interlock meets TB140 guidelines
S&S Northern’s Merlin CT1650 gas interlock product is designed for commercial kitchens and supports the TB140 guidance by The Gas Safety Register and IGEM, which states that a secondary backup in the form of a carbon-dioxide detector may be used in commercial kitchens if the ventilation system fails.
When used alongside a CO2 detector, the Merlin CT1650 allows a kitchen to remain operational if the ventilation system fails as long as the quality of the air in the kitchen is within the recommended levels and whilst the ventilation fans are repaired. If the ventilation fails and the CO2 reaches an unacceptable level, the switched output will alert the CT1650 panel, and the gas solenoid valve will close.
In addition, if the CT1650 detects that there is no electrical current going to the fan, an alert will be raised and the gas solenoid valve closed. Once the fans are operational, the gas solenoid valve is allowed to open.
