Claim 0:
1. A fire suppression system comprising:
a feed port;
a channel configured to couple the feed port to an actuation chamber;
a solenoid valve configured to controllably block a connection between the feed port and the channel, wherein pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection;
a piston in communication with the actuation chamber;
an inlet port closed off by a disc;
a pressurized container containing a volume of fire suppressant agent and ullage absent the first suppressant agent in flow communication with the feed port and the inlet port, the piston driven to initially burst the disc via pressure of the ullage on the piston when the solenoid valve unblocks the connection; and
an outlet port coupled to the inlet port;
wherein the piston is configured to be driven in a direction toward the pressurized container when driven to burst the disc.
