Introduction

To give a common understanding of the requirements detailed in the EN 50136 suite of standards covering

alarm transmission, there is a need for application guidelines to provide support to other TC 79 WGs,

standardization bodies, insurance companies and customers, to understand what an appropriate performance

for the alarm transmission system for a specific application should be.

A full understanding of an application or application requirements are not always available to the alarm

transmission experts, and therefore the following guidelines for the application of alarm transmission should

assist the reader to understand the alarm transmission standards and the performance of an alarm

transmission system. The EN 50136 suite of alarm transmission standards apply to many diverse applications

e.g. I&HAS, fire, access control, VSS. Therefore, this guideline should be read in conjunction with the

standards relating to these applications where appropriate.

Several alarm transmission systems may be used by the providers of alarm transmission services, which

imply that the level of services may vary, depending on the performance of each alarm transmission system.

1 Scope

These application guidelines include guidance on the application of the design, planning, operation,

installation, commissioning and maintenance of alarm transmission systems for use in fire, I&HAS, Social

Alarms and VSS applications. This document does NOT specify requirements. The requirements for ATS and

ATE are specified in other parts of the EN 50136 series of standards.

These application guidelines are intended to assist those responsible for establishing an ATS(n) to ascertain

the appropriate design, planning, Installation, operation and maintenance of an ATS(n) and to determine the

most appropriate ATS category for the required system performance. E.g. Installers and service providers,

ATSPs and their ICT managers, Network operators (Telco’s), ARC’s and their ICT managers, Test houses

and Certification inspectorates, Specifiers, Insurance companies, Manufacturers of ATE.

5 General
This clause provides general information and guidelines for ATS.
5.1 Information security
5.1.1 General

Requirements for information security of an ATS are described in EN 50136-1. Information security measures

are mandatory for ATS categories SP4 – SP6 and DP3 – DP4. This should be taken into account when

assessing category requirements for an application. The recommendations in this section apply to systems

that are planned to fulfil the requirements of the ATS categories listed above.

In addition to system and equipment information security protection level requirements, emphasis should be

drawn to operational information security. An ATSP and other parties operating and maintaining one or more

ATS should have a fully documented security policy this will commonly be part of an operations policy,

describing at least following security aspects.
5.1.2 Key management

All keys used to access the system should be created, stored and managed in a way to ensure the keys

cannot be compromised. This is particularly important, where the keys are stored or transferred in a manner

not having inherent security e.g. printed on a piece of paper for commissioning. There should be a

documented procedure to revoke any keys that are no longer trusted for whatever reason.

Unnecessary storage of keys and credentials should be avoided. An SPT should only have the required

credentials to secure communication with RCT(s) but not for anything else. An RCT should have credentials to

secure communication with SPTs, but compromising one RCT should not compromise the whole key

creation/assignment process of an ATSN.

Additional to the requirements of EN 50136-1, security measures should also be taken to provide security for

the (network) equipment, especially at the ARC and at the installer office locations. As alarm messages from

all connected SPTs travel through the network equipment at the ARC it is important that this equipment is

configured to offer a level of security appropriate to the application, a malfunction might affect many SPTs.

The same applies to the network equipment at sites from where remote maintenance is performed, e.g. the

installer office. Storage and privacy of confidential data.

All confidential data, should be stored in a way that minimizes the risk of compromise to confidentiality E.g.

electronic or hard-copy of customer details, system configuration etc. Consideration should be given to

national legislation with respect to data privacy laws.
5.1.3 Access to the ATS and ATSN

Access to ATS equipment should be secure and authenticated according to requirements in the relevant parts

of the EN 50136 series. Access to an ATSN should not be permissible through access to unauthorised parts

of the network.

Any user or party should be granted the lowest level of access needed to perform their operational tasks.

Unnecessary high levels of access should be avoided wherever possible. All access to the system and actions

performed should be logged in a secure manner.
5.1.4 Security screening

Screening of employees who have access to an ATSN should be carried out in accordance with the

requirements of EN 50518 series. The operational policy of an ATSP should describe the level of screening

required for personnel having access to an ATS/ATSN

5.2 Availability
5.2.1 General

Where required for an appropriate ATS category availability measurement and reporting is the responsibility of

the ATSP as defined in EN 50136-1.

Availability is the percentage of time during which the ATS is performing within the specified ATS category

requirements. This is a very important performance criterion for the quality of an alarm transmission System.

If an ATS or ATP performs perfectly every second of every day its performance will be 100 %. If it does not

operate at all, the availability is 0 %.

The measurement of availability of an ATS differs from the availability usually specified by network operators.

The ATS availability according to EN 50136-1 specifies the end-to-end availability of an alarm transmission

system, whereas network availability often only defines the availability of the network. Network availability in

contrast to ATS availability frequently excludes outages due to planned and unplanned maintenance periods.

5.2.2 Single path ATS availability
When a single path is in a fault condition, the ATS is not available.
5.2.3 Dual path ATS availability

When one path of a dual path ATS is fully operational and the alternative path is in total failure, the ATS is still

available. Whilst the path fault persists the dual path ATS will operate as a single path ATS, and any loss of

communication on the remaining path will reduce the availability below 100 %.

The guide for acceptable, ‘weekly’ availability is defined in EN 50136-1 Table 6, and provides requirements for

Single path Systems, and Dual path systems.

SP4, SP5 and SP6 availability targets are 97 %, 99 % and 99,8 % respectively over a one-week period, and

DP2, DP3 and DP4 targets are 99 %, 99,8 % and 99,8 % respectively over the same period.

There are 168 h in a week so the accepted maximum non-operational period for an SP4 at 97 % availability is

5 h, SP5 and DP2 at 99 % availability are 1 h 42 min and SP6, DP3 and DP4 at 99,8 % availability are 20 min.

To meet these weekly availability targets it is important to consider the type of transmission path technology,

the local environment and estimated distances from the premises to the exchange or radio base station.

Proper service level agreements (repair times) should also be considered.

When implementing a Dual path ATS, the availability of each separate ATP may be operating at a much lower

availability than the overall ATS availability.

To meet the weekly availability requirement of DP2 each ATP should operate with 90 % availability, and to

meet DP3 and DP4 each ATP should operate with 95,5 % availability.
An ATS with 99,8 % availability is illustrated in Figure 1 below:
---------------------- Page: 10 ----------------------
SIST-TS CLC/TS 50136-7:2017
CLC/TS 50136-7:2017 (E)
Figure 1 — Illustration of dual path availability

ATP1 is 95,5 % available and 4,5 % unavailable (fault condition); during the 4,5 % time period when ATP1 is

in fault ATP2 is operationally 95,5 % available and 4,5 % unavailable. With the fault period of ATP1 (4,5 %)

covered by ATP2 with 95,5 % availability the fault period expected from both paths reduces to 0,2 % providing

a combined availability of 99,8 %.

To enable the system to monitor the availability of an ATP to the required accuracy for the required availability

measurement the minimum poll rate for DP2 should be better than 1 008 min (11 polls per week = 24 h * 7

days * 60 min * 10 %), and DP3 and DP4 should be 50 min (202 polls per week = 24 h * 7 days * 60 min *

4,5 %).

Polling is a common method used to monitor ATP and/or ATS availability where the term polling means

regular status message exchanges between an SPT and RCT(s). Other methods may be used to achieve the

same results.

5.3 Testing

While testing alarm transmission equipment (SPT and RCT) a test lab should test to demonstrate that the ATS

is able to record and report availability at a level appropriate to the ATS category.

5.4 Certification and inspection

Inspection and certification of an ATS and ATSN differs from single product certification in that the end to end

ATS is to be certified, and should be carried out using a combination of product bench tests and

commissioned system tests. To achieve compliance the following should be tested and/or documented during

certification:

– the maximum number of connected ATSs for each category to the ATSN should be documented;

– the transmission delays and reporting times should be measured for at least ten random ATSs on each

ATSN;

– the availability calculation method and availability records should be inspected for at least ten random

ATSs for each ATSN;

– the fault reporting should be verified for every mandatory fault for at least ten random ATSs for each

ATSN;
---------------------- Page: 12 ----------------------
SIST-TS CLC/TS 50136-7:2017
CLC/TS 50136-7:2017 (E)

– where more than one type of AS and/or network is used for a single ATSN, then the ten random ATSs

should include at least one of each possible combination of AS, network and category.

5.5 The role of the ATSP

Where required by EN 50136-1, an ATSP must exist for the purpose of ATS and ATSN performance

monitoring.

Alarm transmission system design, planning, commissioning and performance monitoring, is typically a

responsibility of the ATSP. An ATSP can be either an independent company, or a sub organization of an ARC,

installer or network service provider. It is not within the scope of this Technical Specification or within the

European standard EN 50136-1, to define who should fulfil this role.

For each and every ATS the ATSP entity (organization) should be clearly identified.

5.6 ATS applications

Alarm reporting can be used for different types of application. Table 2, gives an example of the most

commonly used applications.
