28、 2018 DIGITAL ALARM COMMUNICATOR SYSTEM UNITS - UL 1635 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover digital alarm communicator system units for use in central-station burglar-alarm syste
29、ms, proprietary burglar alarm systems, police station connect burglar-alarm systems, residential burglar-alarm systems, residential re 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 co
30、mmunicator 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 re warning control unit, or f
31、) 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 companys switched ne
32、twork (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 a
33、t the central-station or residential monitoring station. 1.4 If equipment covered by these requirements is intended for use in a combination burglar-alarm and re-protective signaling system, the portion of the equipment serving a re-alarm function shall comply with the Standard for Control Units and
34、 Accessories for Fire Alarm Systems, UL 864. 1.5 Service required to be provided by the central-station is covered by the Standard for Central-Station Alarm Services, UL 827. 1.6 A digital alarm communicator system may be classied as police-station connected if: a) It is used in combination with a p
35、rotected 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 c
36、omplies with the Standard for Central-Station Alarm Services, UL 827.

37、r classied as to extent of protection at each location, according to the requirements covering installation and classication (of extent) of alarm equipment at individual locations as published in the Standard for Installation and Classication of Burglar and Holdup Alarm Systems, UL 681, that should
38、be consulted by burglar-alarm installers. 1.8 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. 1.9 Digital alarm communicator un
39、its for use in residential re warning systems shall comply with the Standard for Household Fire Warning System Units, UL 985, in addition to the applicable requirements in this standard. 1.10 Digital alarm communicator units for use in home health care medical alert systems shall comply with the Sta
40、ndard for Home Health Care Signaling Equipment, UL 1637, in addition to the applicable requirements in this standard. 2 Components 2.1 Except as indicated in 2.2 a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of stan
41、dards covering components generally used in the products covered by this standard. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is supe
42、rseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only und
43、er limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

Values in parentheses are explanatory or approximate information. 3.2 Unless otherwise indicated, all voltage and current values specied in this standard are rms. 4 Undated References 4.1 Any undated reference
45、 to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 5 Terminology 5.1 The term product as used in this standard refers to all types of digital alarm communicator units. 6 Glossary 6.1 For the purpose
46、of this standard, the following denitions apply. 6.2 ACKNOWLEDGMENT SIGNAL An audible and/or visual signal that is sent to the subscriber by the central station to notify the subscriber that a signal has been received indicating that the protection system has been properly armed. The acknowledgment
47、signal is to be sent manually or automatically. 6.3 CIRCUITS, ELECTRICAL: a) High-Voltage A circuit involving a potential of not more than 600 volts and having circuit characteristics in excess of those of a low-voltage power-limited circuit. b) Low-Voltage A circuit involving a potential of not mor
48、e than 30 volts AC rms, 42.4 volts DC or AC peak. c) Power Limited A circuit whose output is limited as specied in Tables 6.1 and 6.2. The power limitation shall be provided by the construction of the transformer, a xed impedance, a noninterchangeable fuse, a nonadjustable manual reset circuit prote
49、ctive device, or a regulating network.
