Scope:

These requirements cover the construction and operation of halocarbon clean agent fire extinguishing system units intended to be installed, inspected, tested, and maintained in accordance with the Standard on Clean Agent Fire Extinguishing Systems, NFPA 2001 and with the National Fire Code of Canada. These requirements also cover halocarbon clean agent automatic extinguisher units that may have a manual means of operation, and are intended to be used in accordance with the manufacturer's installation instructions. Automatic extinguisher units are not intended: a) For use as a general substitute for pre-engineered or engineered clean agent extinguishing system units; or b) For protection of fire risks larger than those specified in the manufacturer's instructions for a single unit by using multiple units.

Project need:

The requirement for marking agent or pneumatic control contents is meant to provide means of identification of the gauge. Typically, agent designation or contents are shown in labels and other documentation in the system. The use of the part number provides equivalent means of identification. The acceptance of the proposal will allow the use of common gauges for different agent references or contents, provided all other technical requirements can be met too. As the proposal is constructed as an alternative approach it does not force any change on existing approved systems.
