Patent attributes
A sprinkler system comprises a network of CPVC conduits and a plurality of sprinklers. The system includes an electrically activated solenoid control valve to allow fluid to flow in the pipe network. One or more fire detectors operate independently of the condition of the sprinklers. Upon detection of an incipient fire situation, a fire detector sends an electrical signal to cause activation of the control valve. Upon activation of the control valve, fire suppression fluid is caused to flow through the conduits before the incipient fire situation matures into a sprinkler-triggering event. The cooling effect of fluid flowing through the conduit enables the conduit to resist structural failure prior to sprinkler deployment. The control valve may be disposed at a remote location in the sprinkler line and be operable as part of an inspector's test connection.
