  • SCOPE

    1 Scope

    1.1 These requirements cover the individual units that comprise a home health care system intended for use in ordinary indoor residential locations.

    1.2 These requirements also cover a complete home health care system in which a signal initiating device (both routine monitoring and medical emergency signals) may be connected directly or indirectly to receiving equipment at a residence or to continuously monitored receiving equipment at a central supervising station. The system is arranged so that a predetermined change in the status of the signal initiating circuits or devices automatically causes transmission of a signal over a communication channel to receiving equipment at a residence, to a central supervising station, or to a private telephone number.

    1.3 The components of the home health care system may include signal initiating devices, control units, transmitters, and digital communicators, all located at the residence, and the receiving, processing, and displaying equipment located at the central supervising station.

    1.4 All field wiring extending to signal initiating units located at the residence is intended to be energized from power limited circuits as defined in 3.3 (c).

    1.5 The units covered by these requirements are intended to be installed in accordance with the requirements of:

    a)    The National Electrical Code, NFPA 70;

    b)    Other applicable installation codes; and

    c)    The local inspection authority having jurisdiction.

    1.6 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves, a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard cannot be judged to comply with this standard. Where considered appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

    1.7 Where a unit employs residential fire alarm functions, it shall comply with the Standard for Household Fie Warning System Units, UL 985. Where a unit employs household burglar alarm functions, it shall comply with the Standard for Household Burglar-Alarm System Units, UL 1023. A unit utilizing non-fire and/or non-carbon monoxide emergency and/or non-emergency signaling functions shall meet the requirements of the Standard for General Purpose Signaling Devices and Systems, UL 2017.
