  • SCOPE

    1 Scope

    1.1 These requirements cover discrete electrical control units, communication units, transport products which manipulate the data packets, interfaces, and accessories for mass notification systems to be employed in accordance with the National Fire Alarm and Signaling Code, NFPA 72.

    1.2 The products covered by this standard are intended to be used in combination with other appliances and devices to form an emergency communication and/or mass notification system. These products are intended to communicate critical information within buildings and/or outdoor areas about emergencies including but not limited to terrorist activities, hazardous chemical releases, severe weather, fire, and other situations that may endanger the safety of the occupants of an area or facility. Communication is through voice and visual instructions, as well as alert and evacuation signals. An installation document(s) provided with the product describes the various products needed to form an emergency communication and/or mass notification system and their intended use and installation.

    1.3 These requirements address emergency service personnel communication system interfaces used in the performance of their duties if that communication equipment is used to interface with or control the ECS/MNS.

    1.4 Audible notification appliances are to be assessed to the Standard for Audible Signaling Devices for Fire Alarm and Signaling Systems, Including Accessories, UL 464, and the Standard for Speakers for Fire Alarm and Signaling Systems, Including Accessories, UL 1480. Visible notification appliances are to be assessed to the Standard for Signaling Devices for the Hearing Impaired, UL 1971, or the Standard for Visible Signaling Devices for Fire Alarm and Signaling Systems, Including Accessories, UL 1638, as applicable. Textual visible appliances are to be assessed to the UL 1638.

    1.5 Products incorporating fire and/or security signaling functions or other life safety systems shall comply with the UL standards applicable to their intended function and application in addition to this standard.

    1.6 Non-fire emergency manual actuating stations shall comply with the requirements of the Standard for General Purpose Signaling Devices and Systems, UL 2017.
