    1.1 These requirements cover:

    a)    Power supplies for use with burglar-alarm systems installed in accordance with the Standard for Installation and Classification of Burglar and Holdup Alarm Systems, UL 681; and

    b)    Power supplies used to provide electrical power and standby power for burglar-alarm equipment constructed in accordance with the following:

    1)    The Standard for Police Station Connected Burglar Alarm Units and Systems, UL 365;

    2)    The Standard for Local Burglar-Alarm Units and Systems, UL 609;

    3)    The Standard for Central-Station Alarm Services, UL 827;

    4)    The Standard for Holdup Alarm Units and Systems, UL 636;

    5)    The Standard for Intrusion-Detection Units, UL 639;

    6)    The Standard for Household Burglar-Alarm System Units, UL 1023;

    7)    The Standard for Antitheft Alarms and Devices, UL 1037;

    8)    The Standard for Proprietary Burglar Alarm Units and Systems, UL 1076;

    9)    The Standard for Central-Station Burglar-Alarm Units, UL 1610;

    10)    The Standard for Digital Alarm Communicator System Units, UL 1635.

    1.2 The input ratings of power supplies covered by these requirements are not more than 300 volts and the output ratings are low-voltage, power-limited. See 3.2.

    1.3 These requirements cover power supplies for use as components in burglar-alarm system units.

    1.4 These requirements do not cover power supplies for use at a central station. Such power supplies are covered by the Standard for Central-Station Alarm Services, UL 827.

    1.5 These requirements do not cover power supplies integral with a burglar-alarm system unit, nor do they cover separate power supplies intended for use with a specific unit. These are covered by the standards specified in 1.1.

    1.6 These requirements do not cover power supplies for use in hazardous locations, as defined in the National Electrical Code, NFPA 70.

    1.7 These requirements do not cover power supplies covered by the Standard for Power Units Other Than Class 2, UL 1012, or battery chargers covered by the Standard for Battery Chargers for Charging Engine-Starter Batteries, UL 1236.

    1.8 With reference to 1.1, the Standard for Police Station Connected Burglar Alarm Units and Systems, UL 365; the Standard for Local Burglar Alarm Units and Systems, UL 609; the Standard for Proprietary Burglar Alarm Units and Systems, UL 1076; the Standard for Central-Station Burglar-Alarm Units, UL 1610; and the Standard for Digital Alarm Communicator System Units, UL 1635, contain requirements for attack resistance against a power supply providing energy to a local audible alarm sounding device or to a device that will transmit a signal from the protected area to a remote location, such as a central station or police station. A power supply complying with the requirements of this standard that is to be used for any of these purposes shall be capable of being mounted inside an enclosure that will provide the required attack resistance, or shall be provided with an enclosure that will provide the required attack resistance. See UL 365, UL 609, UL 1076, UL 1610, and UL 1635 to determine the attack resistance requirements that will apply.
