  • SCOPE

    1 Scope

    1.1 These requirements cover the construction and operation of water-based automatic extinguisher units intended for total flooding applications when installed, inspected, tested, and maintained in accordance with the manufacturer’s instructions.

    1.2 Automatic extinguisher units do not have a manual means of operation, and are not intended for protection of fire risks larger than those specified in the manufacturer’s instructions for a single unit by using multiple units.
