Scope:

1.1  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.

1.2  Alarm valves covered by these requirements include the sizes 1 – 12 inches, inclusive.

1.3  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.

Project need:

AHJs are increasingly reluctant to use ORDs for regulatory requirements. There is an existing ORD that has surpassed its 5 year maintenance cycle and is no longer valid. Regulators have requested that we convert ORD in to a standard. This activity will result in a joint Canada/US standard. Manufacturers will benefit from reduced administrative burden when product only needs to be tested to a single standard. Regulators will benefit from reduced overlap in standards requirements. The proposal is to convert an already existing UL standard into a Joint Canada-U.S. National Standard by incorporating requirements from ULC/ORD-C193-75, Guide for The Investigation of Alarm Valves for Fire-Protection Service.

The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.
