Abstract
The fire suppression system includes a system piping, with at least one sprinkler, a flow control valve, a fire suppressant delivery line in fluid communication with the flow control valve, at least one fire detector adapted to detect temperatures associated with fire, and a control system. The control system is in communication with the fire detector, the flow control valve and the system piping. The control system is adapted to detect a flow condition and a no-flow condition in the system piping and actuates the flow control valve between a normally open condition and a closed condition when the fire detector is in a no-fire condition state and the control system detects a flow condition in the piping system and may cycle the flow control valve to open when the flow control valve is closed in response to the fire detector being in a fire condition state.
