ABSTRACT:
A sprinkler system having a pressurized sprinkler conduit which is separated from a water supply by a normally closed valve, and a fire alarm system having a circuit which is connected with this valve and opens the same in response to the detection of a fire by the circuit, is operated by detecting the absence of electrical energization of the fire alarm circuit, and thereupon operating the sprinkler system as a function of pressure losses in the sprinkler conduit rather than as a result of the operation of the fire alarm system.
