Abstract
A fire suppression system includes a feed port and a channel to couple the feed port to an actuation chamber. A solenoid valve controllably blocks a connection between the feed port and the channel. Pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection. A piston is in communication with the actuation chamber. The system also includes an inlet port closed off by a disc. The piston travels through the inlet port and burst the disc based on the pressure in the actuation chamber. An outlet port is coupled to the inlet port.
