ABSTRACT:
A fire suppression system includes system piping and at least one sprinkler with the system piping for delivering fire suppressant to the sprinkler. The sprinkler has an outlet and a temperature sensitive trigger with temperature sensitive trigger opening the outlet for dispersing fire suppressant when sensing temperatures associated with a fire condition. The system also includes a deluge valve that is in selective fluid communication with the system piping and has a normally closed condition whereby the system piping is normally dry. The deluge valve controls the flow of suppressant to the system piping and the sprinkler. A control system, which is in communication with at least one source of power, opens the deluge valve in a fire condition when the power source is in a powered condition and opens the deluge valve in a loss of pressure condition when the power source is in a loss of power condition.
