35、TRODUCTION 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 an
36、d 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 devic
37、es 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, transmitter
38、s, and digital communicators, all located at the residence, and the receiving, processing, and displaying equipment located at the central supervising station. 1.4 All eld wiring extending to signal initiating units located at the residence is intended to be energized from power limited circuits as
39、dened in 5.3 (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 Where a unit employs res
40、idential re 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-re and/or non-carbon monoxi
41、de emergency and/or non-emergency signaling functions shall meet the requirements of the Standard for General Purpose Signaling Devices and Systems, UL 2017.

42、TION WITHOUT PERMISSION FROM UL 2 Components 2.1 Except as indicated in 2.2, a component of a unit covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the units covered by this standard. 2.2 A co
43、mponent need not comply with a specic requirement that: a) Involves a feature or characteristic not needed in the application of the component in the unit covered by this standard or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its recognized r
44、ating established for the intended conditions of use. 2.4 Specic components are recognized as being incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied li
45、mits and shall be used only under those specic conditions for which they have been recognized. 2.5 If a digital alarm communicator transmitter is used to transmit signals to a remote location and is to be included as a component of the system, it shall comply with the applicable requirements in the
46、Standard for Digital Alarm Communicator System Units, UL 1635. Otherwise the user must be notied that the off-premises transmission method has not been so investigated. 3 Units of measurement 3.1 When a value for measurement is followed by a value in other units in parentheses, the rst stated value
47、is the requirement. 3.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 4 Undated references 4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the lates
48、t edition of that code or standard.
