  • SCOPE

    1 Scope

    1.1 These requirements cover digital alarm communicator system units for use in central-station burglar-alarm systems, proprietary burglar alarm systems, police station connect burglar-alarm systems, residential burglar-alarm systems, residential fire warning systems, and home health care medical alert systems.

    1.2 As covered by these requirements, a digital alarm communicator system consists of a digital alarm communicator transmitter interconnected to or integral with:

    a)    a central-station burglar-alarm control unit,

    b)    a proprietary burglar alarm control unit,

    c)    a police-station-connect burglar-alarm control unit,

    d)    a residential burglar-alarm control unit,

    e)    a residential fire warning control unit, or

    f)    a home health care medical alert control unit.

    A need for off premises transmission will activate the digital alarm communicator transmitter that contacts a digital alarm communicator receiver located at a central-station or residential monitoring station through the telephone company's switched network (dial system) and transmits a message identifying the change in condition at the protected premises or residence.

    1.3 The operation of a digital alarm communicator system is under the control of the owner or others interested in the property, the occupants of the residence, and the operators at the central-station or residential monitoring station.

    1.4 Deleted effective December 16, 2006

    1.5 If equipment covered by these requirements is intended for use in a combination burglar-alarm and fire-protective signaling system, the portion of the equipment serving a fire-alarm function shall comply with the Standard for Control Units and Accessories for Fire Alarm Systems, UL 864.


    1.5 revised March 20, 2015

    1.6 Service required to be provided by the central-station is covered by the Standard for Central-Station Alarm Services, UL 827.


    1.6 revised December 16, 2004

    1.7 A digital alarm communicator system may be classified as police-station connected if:

    a)    It is used in combination with a protected premises control unit, an alarm sounding device, and an alarm housing that complies with the Standard for Police Station Connected Burglar-Alarm Units and Systems, UL 365, and

    b)    The signals are transmitted to a digital burglar-alarm communicator receiver located at a central-station that complies with the Standard for Central-Station Alarm Services, UL 827.


    1.7 revised December 16, 2006

    1.8 Devices installed on individual properties are further classified as to extent of protection at each location, according to the requirements covering installation and classification (of extent) of alarm equipment at individual locations as published in the Standard for Installation and Classification of Burglar and Holdup Alarm Systems, UL 681, that should be consulted by burglar-alarm installers.


    1.8 revised effective December 16, 2006

    1.9 Digital alarm communicator units for use in residential burglar-alarm systems shall comply with the Standard for Household Burglar-Alarm System Units, UL 1023, in addition to the applicable requirements in this standard.

    1.10 Digital alarm communicator units for use in residential fire warning systems shall comply with the Standard for Household Fire Warning System Units, UL 985, in addition to the applicable requirements in this standard.

    1.11 Digital alarm communicator units for use in home health care medical alert systems shall comply with the Standard for Home Health Care Signaling Equipment, UL 1637, in addition to the applicable requirements in this standard.

    1.12 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 or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the 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 does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
