CA 2560020

A gas charged fluid flow line of a dry pipe sprinkler system is continuously monitored to detect rate of loss of pressure (dp/dt). The rate of pressure loss is used to detect whether there is an open sprinkler head in a sprinkler grid of the system. Detection of an open sprinkler head and opening of a dry valve may occur in a matter of a few seconds, allowing for a quick response to a fire condition and accurate discrimination of a ~ pressurized gas leak condition. The system may operate at charge pressures in the range of about 7 psig to about 15 psig.
