Abstract
Apparatus and method for converting a fire suppression system from a single interlock electric or double interlock electro-pneumatic system to a single interlock pneumatic system which draws no electrical power. A pneumatic actuator is in fluid communication with a pressurized piping network and a control valve controlling flow of fire suppressant to the network. The pneumatic actuator is isolated from the piping network by a check valve and a latching solenoid valve. In the event of a power failure the latching solenoid valve is opened, placing the pneumatic actuator in fluid communication with the piping network. Electrical power is drawn only to change the state of the latching solenoid valve, it otherwise draws no power. When the latching solenoid valve is open the pneumatic actuator controls actuation of the control valve, and triggers the control valve when there is a pressure change in the piping network indicative of a fire.
