Overview

Multiple Jet Controls are “Quartzoid” bulb detection devices fitted into a detector airline to bring a group of high velocity waterspray open nozzles into action under fire conditions. In the event of a fire, the Multiple Jet Control head nearest to the seat of the fire will activate at a pre-determined temperature.  This causes the air pressure within the detection airline system to drop.

The immediate drop in air pressure within the detector line releases the pressure against the Deluge valve diaphragm unit causing the Deluge Valve to open and discharge water through all the open high velocity waterspray nozzles to rapidly cool, control and extinguish the fire.

Multiple Controls are available in 20, 25, 32 40 or 50mm sizes.
