Description

These requirements cover alarm valves for use in automatic wet-pipe sprinkler systems for fire-protection service. Alarm valves covered by these requirements are of either the variable or constant-pressure type and are of the swing-check pattern. Ordinarily, variable-pressure alarm valves will prove suitable for constant-pressure service without alteration, but in certain designs the portion of the device that has to do with the delaying of alarms may be omitted.

Requirements for the installation and use of alarm valves are included in the Standard of the National Fire Protection Association for the Installation of Sprinkler Alarm Systems, NFPA No.13-1972. Published 2/28/1975.
