English -- UL Standard for Safety Alarm Valves for Fire-Protection Service - Eleventh Edition
Organization:
UL - UL
Year: 2016
Abstract: Scope: 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 are acceptable for constant-pressure service without alteration; however, in some designs, that part of the device having to do with the delaying of alarms may be omitted. Alarm valves covered by these requirements include the sizes 1 – 12 inches, inclusive. Alarm valves covered by these requirements are intended for installation and use in accordance with the Standard for the Installation of Sprinkler Systems, NFPA 13.
