EN 50134-5:2021 includes the following significant technical changes with respect to EN 50134-5:2004:

— The minimum performance parameters for the interconnection including availability, monitoring, security,

transmission time are now determined by updated reference to EN 50136-1:2012 .

— Requirements for microphone and speaker performance to deliver two-way speech have been removed

and are now determined with EN 50134-3:2012.

— Requirements for the alarm transmission system have been updated to take account of the general

migration of voice traffic to packet-based IP infrastructures by telecommunications providers.

— The minimum technical performance requirements of the alarm transmission system are now prescribed

by updated reference to EN 50136-1:2012 .

— The requirements for an ATS used within social alarm systems are set out as custom categories utilizing

performance metrics drawn from more than one standardized ATS configuration class described with

EN 50136-1:2012 .

— Performance parameters are now prescribed for both sessional connected, switched paths or packed

switched networks.

— Different technical performance requirements for the alarm transmission system now included for a

controller designed for use with one local unit or multiple local units.

— Requirements have been added where digital to analogue or analogue to digital signal conversion is

utilized.

— Requirements have been added where a digital to analogue conversion unit undertakes translation

between an analogue signalling protocol and a digital signalling protocol.

— Account has been taken of the increasing use of logical alarm triggering where data from several sources

are combined to determine whether a specified alarm triggering condition has been met. Minimum

requirements are now included logical alarm triggering from any of the following: trigger device, local unit

and controller, device provisioning and management platform and the alarm management system.

— Security requirements including design considerations, use of cryptographic algorithms and security

Introduction

A social alarm system provides 24 h facilities for alarm triggering, identification, signal transmission, alarm

reception, logging and 2-way speech communication, to provide reassurance and assistance for people

considered to be at risk.

The social alarm system provides streaming media between the local unit, the controller and the alarm

receiving centre. As a minimum it is in the form of voice communication but in addition it may include, status

data, video and voice or other continuous streaming data. Alarm, fault, and status messages may be received

and processed at a single, multiple or different ARC’s.

The social alarm system can include one or many trigger devices connected to the local unit and/or controller

via interconnections, the security and integrity of which are essential to proper operation of the alarm system.

As communications providers continue to migrate towards Next Generation Networks they are increasingly

converging voice traffic onto their packet based IP infrastructures, which might no longer have a regulatory

requirement to support in-call DTMF tones. This could have an adverse impact on the reliability of in-call tone-

based protocols used in social alarm systems, which could drive future systems development to the use of

communication protocols engineered for packet based transmission environments.

Social alarm systems are part of a family of alarm systems sharing common standards for aspects such as the

performance characteristics of the alarm transmission system. These common performance metrics are

defined within the EN 50136 series and this document selects the appropriate performance parameters for

social alarm systems by reference to the EN 50136 series.

4.1 General requirements

The interconnections shall be designed to provide a reliable means of communication between triggering

devices, the local unit(s) and the controller. The interconnection may be wired and/or wireless.

The interconnections shall be regarded as an element in a series of connected alarm transmission paths

towards the alarm receiving centre.
---------------------- Page: 12 ----------------------
SIST EN 50134-5:2021
EN 50134-5:2021 (E)

The minimum performance requirements for alarm transmission shall be as stated in 4.3. Where the

interconnections are used for the transmission of additional services e.g video, habit monitoring data,

actimetry, the performance available to alarm transmission shall not be diminished.

4.2 Wireless

For wireless interconnections via RF, frequencies designated for low duty cycle high reliability

equipment/social alarm systems) shall be used for the transmission of alarm and fault signals.

If the RF interconnection is delivered using alternative frequencies, mitigation techniques for ensuring reliable

communication as described in Table 1 shall be applied.

with acknowledgement

NOTE Mitigation techniques in UWB include “Detect and Avoid” and “Low Duty Cycle”.

If other types of RF communication are used, similar mitigation techniques for polite spectrum access and

acknowledgement should be applied.
4.3 Availability

The interconnections in a social alarm system shall have an availability that fulfils the requirement set out in

, Table 6, class SP6.
EN 50136-1:2012

The necessary availability is calculated using the methodology in 8.6.6 within this document.

4.4 Monitoring

For wired and wireless trigger devices the interconnections shall be monitored for availability.

For interconnections the maximum permitted interval between periodic communications signals or messages

shall be according to EN 50136-1:2012 , Table 3, SP2.

For interconnections between wired trigger devices and the Local Unit and controller the maximum reporting

time shall be according to EN 50136-1:2012 , Table 3, SP5.

Portable trigger devices may be removed from the designated operating area as identified in

EN 50134-7:2017, Clause 8 e) and, in this case, will be reported as a fault signal or status message.

For interconnections between multiple local units and a controller the maximum permitted interval between

periodic communication signals or messages shall be according to EN 50136-1:2012 , Table 3, SP6.

4.5 Security

In alarm systems there is a risk of malicious substitution of radio signals to generate false alarm or fault

signals. Whilst in other applications of alarm systems malicious substitution could pose a significant risk to

system integrity, in the case of social alarms this risk is viewed as minimal and this document makes no

requirements for preventative techniques.

door entry, internet provision this usage should not impact or degrade the performance of the interconnection

for social alarm applications as described in this document.
4.8 Two-way speech communication

The interconnection should have sufficient capacity to deliver the bandwidth requirements for the number of

rated sessions without degradation from the performance requirements set out in 4.6.Capacity management

Where multiple trigger devices are connected to a local unit and controller this shall not impact or degrade the

performance of the interconnection (availability, transmission and reporting time)

5 Communications
5.1 Commentary

An ATS or ATP may include permanent dedicated links, permanent virtual links or switched links which may

use equipment that is not covered by the requirements of EN 50136-2, EN 50136-3 and this document or may

be affected by other applications sharing the transmission links.
An ATP may include:

a) a transmission link that is shared with non-alarm data applications e.g. video or corporate LAN traffic,

streaming entertainment
b) a transmission link that carries other ATPs,

c) equipment from a third-party transmission network provider, which is not located at either the user’s

premises or the alarm receiving centre and is not classified as ATE,

d) equipment from a third party which is located at the user’s premises but is not classified as ATE.

The performance (reliability) of an ATS could be affected by:

e) unwanted, malformed or otherwise malicious incoming data at the interfaces of the SPT or RCT,

f) transmission network congestion as a result of transmission link sharing,

g) transmission network unavailability due to equipment failure and/or maintenance.

NOTE Alarm transmission equipment includes the termination e.g. ATA to the alarm transmission path.

5.2 General requirements

The alarm transmission system in a social alarm system shall meet the requirements within

EN 50136-1:2012 .

The alarm transmission system shall support, as a minimum, the following communications: two-way audio,

alarm and fault signals, and status messages.
