DELUGE SYSTEM ELECTRIC ACTUATION

A deluge fire sprinkler system with electric actuation operates through coordinated interaction between a detection and suppression network. The system’s open sprinklers or nozzles remain unpressurized until activation of the deluge valve. The deluge valve, which controls water entry into the piping network, is held closed by system water pressure within a diaphragm chamber, sometimes referred to as a pressure or control chamber on the deluge valve. When the electric detection system—comprising heat, flame, or smoke detectors—senses fire conditions, it signals a releasing control panel. The panel energizes a solenoid-operated release valve on the trim piping of the deluge valve, venting the deluge valve’s diaphragm chamber or pressure chamber and causing the deluge valve to open fully. Water then floods the system piping and discharges simultaneously through all open sprinklers or nozzles. The control panel may also activate alarms, pumps, or other suppression devices. Once activated, the system continues to flow until manually shut down and reset, ensuring a rapid and total water discharge across the protected area.
