Claim 6:
7. A fluid control system, comprising:
a diaphragm valve, comprising:
a diaphragm chamber defining a diaphragm port;
an inlet;
an outlet; and
a diaphragm to move, in the diaphragm chamber, based on a release of fluid from the diaphragm chamber through the diaphragm port, between a first state sealing the inlet from the outlet and a second state allowing fluid flow between the inlet and the outlet;

a first electrical control point coupling the diaphragm port with a first fluid line, the first electrical control point to change, responsive to being energized, from a first state to a second state to reduce fluid flow from the first fluid line into the diaphragm chamber through the diaphragm port;
a second electrical control point coupling the diaphragm port with a second fluid line extending to a vent, the second electrical control point to change, responsive to being energized, from a third state to a fourth state to increase fluid flow from the diaphragm chamber into the second fluid line out of the vent; and
a controller to transmit a first electrical signal to energize the first electrical control point, responsive to detecting a fire condition, and transmit a second electrical signal to energize the second electrical control point, responsive to detecting the fire condition, the controller to detect the fire condition responsive to a detection signal from a fluid detector coupled with an outlet side of the diaphragm valve, the detection signal indicating at least one of pressure or flow rate.
