ABSTRACT:
An automatic fire suppression unit and method for use in various fire exposures where the area in which a fire can occur is limited, manually operated portable extinguishment is either impractical or not recommended, the ability to provide additional suppression in the event of re-ignition is crucial to fire safety, or the ability to limit environmental impact of the fire suppressant is desired. The system includes a tank containing a suitable fire extinguishing agent and equipped with a temperature activated valve to discharge the extinguishing agent when a thermocouple or metallic alloy element responds to a high temperature condition and opens the valve. When the fire has been suppressed and a high temperature condition no longer exists, the valve automatically closes and stops the discharge of suppressant. Position indication contacts within the valve are utilized to activate appropriate alarms and to remove electrical or gas supply if necessary.
