Claim 0:
1. A fluid control assembly, comprising:
a first solenoid valve coupled with a diaphragm port of a diaphragm valve, the first solenoid valve to change, responsive to a first electrical signal, from a first open state allowing fluid flow into the diaphragm port from a first fluid line to a first closed state preventing fluid flow into the diaphragm port from the first fluid line;
a second solenoid valve coupling the diaphragm port with a second fluid line extending to a vent, the second solenoid valve to change, responsive to a second electrical signal, from a second closed state preventing fluid flow from the diaphragm port out of the vent through the second fluid line to a second open state allowing fluid flow out through the second fluid line; and
a controller to transmit the first electrical signal responsive to detection of a fire condition and transmit the second electrical signal responsive to detection of 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.
