Fixed Condensed Aerosol Extinguishing System Units
Scope:
These requirements cover the construction and operation of fixed condensed aerosol extinguishing system units inclusive of aerosol generating extinguishing system units and aerosol generating automatic extinguisher units intended for total flooding applications when installed, inspected, tested, and maintained in accordance with the Standard for Fixed Aerosol Fire Extinguishing Systems, NFPA 2010 and the National Fire Code of Canada. Aerosol generating automatic extinguisher units do not have a manual means of operation, and are not intended: a) For use as a general substitute for aerosol generating extinguishing system units; or b) For protection of fire risks larger than those specified in the installation instructions for a single unit by using multiple units.
Project need:
The amendment revision to ANSI/CAN/UL/ULC 2775 is to permit the inclusion of a manual method of actuation for automatic extinguisher units in addition to the required automatic thermal method of actuation. This proposal will make the requirements less restrictive. This proposal aligns with the revision of the Standard for Halocarbon Clean Agent Extinguishing System Units, ANSI/CAN/UL/ULC 2166, Edition 3 dated 2019-10-21.
