ABSTRACT:
A fire sprinkler control apparatus which is adapted for connection between a network of connecting fluid flow lines which terminate in sprinkler heads and a water supply. The apparatus consists of a conduit having a first end and a second end. The first end is secured to a water supply and the second end is secured to a network of connecting lines. A solenoid valve is positioned at the first end of the conduit such that the flow of water from the water supply through the conduit to the connecting lines is controlled. An expansion tank is connected to the conduit. A sniffer valve is provided for coupling the conduit to an air source, such that the conduit, the expansion tank and all connecting lines may be pressurized with gas. A pressure switch is connected to the solenoid valve and with the conduit. The solenoid valve is opened to release water from the water supply into the conduit should the pressure in the conduit drop below a preset level.
