Abstract: A residential or commercial sprinkler system is provided wherein the sprinkler heads and piping distribution network are provided with a relatively low pressure fire suppressant liquid in place of pneumatic pressure, which is typical, and control valve keeps fire suppressant supply pressure from entering the discharge sprinkler system at design discharge pressure until a fire detection system detects a fire condition. Upon the detection of a fire condition, a control valve is opened to provide the sprinkler heads and piping distribution network with a fully pressurized supply of fire suppressant. Also in the case of electric control power loss the system will operate from loss of outlet supervised pressure releasing sprinkler liquid suppressant to the discharge system of closed fused sprinklers.

Fire protection system
Charles F Willms
- 26 Jul 1976
TL;DR: In this article, a fire protection system for several zones of protection utilizes an expensive extinguishing agent and directs it only to a zone in which a sensing device indicates the presence of a fire, thus enabling the supply of the extinguishing agents to be delivered only to the fire zone and avoiding the necessity of charging the remainder of the system.
