pdf MJC 80mm - heat & electrically activated, 5mm bulb / Standard A, Double Outlet

GW Multiple Jet Controls (MJC’s) are for use in sprinkler or waterspray systems where it is required to operate small groups of open sprinklers or water spray nozzles simultaneously.

Each MJC contains a frangible glass bulb sensitive to heat. The bulb is pre-loaded at the factory to hold a Nickel / Silver plate against a Brass seal and provide a water and air tight seal. Activation of the Metron actuator by passing a small electrical current through it causes a pin to be extended bursting the glass bulb and actuating the MJC. In addition the application of heat will also burst the bulb releasing the disc and allowing water to flow.

GW MJC’s are available with bulb temperatures of 57ºC, 68ºC, 79ºC, 93ºC and 141ºC.
