S&S Northern Gas Interlock Systems

S&S Northern is the UK manufacturer behind the Merlin range of gas-proving and gas-interlock systems, found in commercial kitchens, boiler houses, and plant rooms nationwide. Merlin panels check the pipework is safe before the gas supply opens and cut the gas automatically the moment extract ventilation fails, the heart of BS 6173 compliance in a commercial kitchen. As a trusted distributor of S&S Northern, we stock the complete interlock line-up: the 2000S and CT1200S kitchen panels, the 1000BH boiler house controller, plus GoldSeal gas solenoid valves, current switches and air pressure switches.

Data centre cabling and equipment protected by Merlin WLM water leak detection

A water leak does its worst damage in the rooms you can least afford to lose: data centres, comms rooms, plant rooms and the risers of apartment blocks. The Merlin WLM watches for it around the clock, using sensing cable or point probes to catch a leak the moment it starts. The controller sounds its built-in alarm, can close a water solenoid valve automatically and reports to BMS controls, with cable fault monitoring as standard and S&S Northern's three year warranty behind every system.
