32、SOCIAL ALARM SYSTEMS Part 2: Trigger devices FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on al
33、l questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publi
34、cation(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. I
35、EC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of o
36、pinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made t
37、o ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparen
38、tly to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certif
39、ication bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shal
40、l attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including lega
41、l fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publ
42、ication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62851-2 has been prepared by IEC technical committee 79
43、: Alarm and electronic security systems. This first edition is based on EN 50134-2:1999. The text of this standard is based on the following documents: FDIS Report on voting 79/457/FDIS 79/468/RVD Full information on the voting for the approval of this standard can be found in the report on voting i
44、ndicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 62851-2:2014 IEC 2014 5 A list of all parts in the IEC 62851 series, published under the general title Alarm and electronic security systems Social alarm systems, can be found on the
45、 IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, repl
46、aced by a revised edition, or amended. 6 IEC 62851-2:2014 IEC 2014 INTRODUCTION This standard is part of the IEC 62851 series of International Standards and Technical Specifications “Alarm and electronic security systems Social alarms systems“, written to include the following parts: Part 1: System
47、requirements Part 2: Trigger devices Part 3: Local unit and controller Part 5: Interconnections and communications Part 7: Application guidelines (under consideration) A social alarm system provides 24 hours facilities for alarm triggering, identification, signal transmission, alarm reception, loggi
48、ng and 2-way speech communication, to provide reassurance and assistance for people living at home or at places under surveillance and considered to be at risk. A social alarm system is comprised of a number of system parts which can be configured in different ways to provide this functionality. A u
49、ser can request assistance by the use of a manually activated trigger device resulting in an alarm triggering signal. In certain cases, alarm triggering signals can be generated by automatic trigger devices. A local unit or controller receives the alarm triggering signal, switching from the normal to the alarm condition and indicating this to the user (some systems use an optional pre-alarm condit
