Alarm and electronic security systems - Social alarm systems - Part 3: Local unit and controller

IEC 62851-3:2014 specifies the minimum requirements and tests for local units and controllers forming part of a social alarm system. This International Standard applies to local units and controllers that receive an alarm triggering signal from manually or automatically activated trigger devices and convert this into an alarm signal for transmission to the alarm receiving centre or an alarm recipient. The design should also take into consideration situations where the user may be unable to send an alarm, or where an unwanted alarm may be sent, due to technical malfunctions or poor ergonomic design.

Systèmes d'alarme et de sécurité électroniques - Systèmes d'alarme sociale - Partie 3: Unité locale et contrôleur

L'IEC 62851-3:2014 spécifie les exigences minimales et les essais destinés aux unités locales et aux contrôleurs constituant une partie d'un système d'alarme sociale. La présente Norme internationale s'applique aux unités locales et aux contrôleurs recevant un signal de déclenchement d'alarme provenant d'un déclencheur activé manuellement ou automatiquement, et convertissant ce signal en un signal d'alarme destiné à un centre de réception d'alarme ou au destinataire de l'alarme. Il convient également que la conception tienne compte des situations dans lesquelles l'utilisateur peut ne pas être en mesure d'envoyer une alarme, ou dans lesquelles une alarme indésirable peut être envoyée en raison de dysfonctionnements techniques ou d'une conception ergonomique peu efficace.

Publication(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. IEC 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 opinion 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 to 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

transparently 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 certification 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.

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 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, logging 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 user 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 condition that allows the user to reset the alarm for a short period

of time).

The controller normally transmits the alarm condition to an Alarm Receiving Centre (ARC) via

the alarm transmission system. The ARC can either be local to the controller or remote from

the controller. The ARC has the facility to identify the local unit, alarm type and to then

establish two-way speech communication between the alarm recipient and the user. The

alarm recipient provides reassurance to the user and directs assistance where appropriate.

In some cases, the alarm may be diverted to an alarm recipient using a personal receiver. In

this case, the alarm is identified to the alarm recipient and a two-way speech communication

path established to the user and receipt of the alarm acknowledged to the controller. In all

cases, the system records the time, date, location and type of alarm.

The system is designed to detect and report fault conditions affecting the transmission of

alarms. In some cases, temporary disconnection of a local unit is possible to minimize faults

or prevent alarms triggered inadvertently affecting the correct operation of the system.

Part 3: Local unit and controller
1 Scope

This part of IEC 62851 specifies the minimum requirements and tests for local units and

controllers forming part of a social alarm system.

This International Standard applies to local units and controllers that receive an alarm

triggering signal from manually or automatically activated trigger devices and convert this into

an alarm signal for transmission to the alarm receiving centre or an alarm recipient.

The local unit and controller may be either separate units or integrated into one unit.

The design should also take into consideration situations where the user may be unable to

send an alarm, or where an unwanted alarm may be sent, due to technical malfunctions or

poor ergonomic design.
