Sensors placed either side of the ductwork fan monitor air pressure. They are connected to an air differential switch, which is activated when the pressure difference changes. Alternatively the current taken by the fan can be monitored by a fan power sensor. The 230V G.I.S. monitors this switch/sensor and in the event of fan failure will close the gas solenoid and cut off the gas flow to kitchen appliances. (Top of Page)
WHEN IS A GAS INTERLOCK SYSTEM A MANDATORY REQUIREMENT?
On installation of a completely new extraction/ventilation canopy
On installation of a completely new gas pipework run
On installation of a completely new cook line or layout
With any fitting of Category 'B' equipment e.g. combination ovens, deep fryers, grills, charcoal griddles. This includes replacements to an existing layout (Top of Page)
Most compact Gas Interlock System on the market :: Most competitively priced Gas Interlock System available :: Simple operation and manual override :: Gas Solenoid Valves and Differential Air Pressure Switch
Oxford Hardware have now introduced a new, improved and evolved Gas Interlock System. With overrides phased out, some of the new GIS range come with twin sensors to allow cooking to continue while an engineer is called out. The 'R' model has an emergency cut off switch built in.
