4 Requirements
4.1 General

Components of IAS with usage of RF links shall comply with the following requirements.

4.2 Immunity to attenuation
4.2.1 General

Due to the fact that there may be changes in the passive environment after installation, it shall be possible to

temporarily reduce or simulate the reduction of the RF link budget during installation or maintenance.

4.2.2 Requirement for immunity to attenuation

The manufacturer shall specify in the installation and maintenance documentation the means used on its

equipment to fulfil this requirement.

This function shall be automatically activated by the system itself when the system is in maintenance or

installation mode.

In this installation condition, the reduction shall be according to the values given in Table 1. This applies to

all links e.g. to CIE, RE, SPT and WD.
Table 1 — Immunity to attenuation
Reduction of the RF link budget
Grade 1 ≥ 8 dB
Grade 2 ≥ 8 dB
Grade 3 ≥ 15 dB
Grade 4 ≥ 15 dB
NOTE The requirements given in Table 1 do not apply to portable
devices (e.g. key fob)

EN 50131-5-3:2017
4.3 Immunity to collision
4.3.1 General

The objective of the requirement and the process of decoding is to ensure a high level of confidence in the

transmissions of alarm and monitoring messages thus reducing the probability of equipment on the same

system causing interference by design and possibly leading to loss or corruption of information.

4.3.2 Requirement for occupation rate

To keep the occupation rate as small as possible, the following requirements given in Table 2 shall be

fulfilled. This rate shall be calculated by assuming the system is at its full capacity.

Table 2 — System occupation of the medium
Maximum occupation In a period of time of
(percentage)
Grade 1 10 % 240 min
Grade 2 10 % 120 min
Grade 3 10 % 100 s
Grade 4 10 % 10 s

To ensure successful transmissions for grade 3 and grade 4 equipment, all types of messages (e.g. alarm,

monitoring) shall be acknowledged by the receiving equipment to the transmitting equipment.

4.3.3 Requirement for throughput ratio

The objective of this requirement is to measure the ability of all receiving equipment to interpret and decode

radio messages accurately.
Receiving equipment shall comply with the requirements of Table 3.
Table 3 — Throughput ratio
Minimum number of
correctly interpreted
messages
All grades 999 out of 1 000
4.4 Immunity to substitution
4.4.1 General

Intentional message or component substitution generally attempts to reduce the security of the system.

Unintentional message or component substitution generally causes false alarms or tamper alarms and has a

nuisance value.
4.4.2 Immunity to unintentional message and component substitution

In order to prevent unintentional message and component substitution, each transmitting device shall be

identified as belonging to the system by an identification code. The number of identification code possibilities

shall be at least equal to those shown in Table 4.
---------------------- Page: 10 ----------------------

Grade 1 100 000
Grade 2 1 000 000
Grade 3 10 000 000
Grade 4 100 000 000

Alternatively the manufacturer shall provide means to the installer on site to choose identification code with

the minimum of 256 codes to ensure that an alarm shall not interfere with other nearby systems.

4.4.3 Immunity to intentional messages and components substitution

In accordance with EN 50131-3 for grade 4 equipment, means to monitor and to detect messages and

components substitution are required.
4.5 Immunity to interference
4.5.1 General

The purpose of this requirement is to check the ability of the receiving equipment to discriminate between the

desired signal and the interfering RF signals.

This immunity to interference requirement applies to the receiving equipment as listed below:

— CIE;
— WD;
— RE;
— SPT.

Each of the interference signals defined below shall be applied and shall not cause false alarm, indications of

a failure of periodic communication and shall not compromise the correct reception and processing of the

messages.

During continuous application of the interfering signals whose levels are defined in the subsequent

subclauses, all of the 20 system relevant messages (sent by the transmitting equipment used for test

purposes) shall be correctly received and processed by the receiving equipment.

In the event of the receiving equipment operating in more than one assigned band, the requirement shall be

fulfilled for each individual assigned band.
4.5.2 Interference outside the assigned band for equipment of all grades

The receiving equipment shall be fully functional during the application of the interference signal at a level of

10 V/m at frequency F and subsequently at frequency F (F and F are defined in 5.5.1).

1 2 1 2
4.5.3 Interference within the assigned band for equipment of all grades

The receiving equipment shall be fully functional during the application of the interference signal at a level of

RL + 8 dB (RL is defined in 5.1) at frequency Ft (Ft is defined in 5.5.1).
4.5.4 Interference within the assigned band for grade 3 and grade 4 equipment

Additionally, the receiving equipment shall be fully functional when an interference signal is applied to each

assigned band sequentially at a level, IL + 3 dB (IL is defined in 5.5.4) with a frequency modulated signal as

defined in 5.5.4.

4.6 Requirement for RF links monitoring
4.6.1 General

The RF links shall be monitored in accordance with the grade. The indication or notification related to RF link

monitoring is dependent on the grade and the state of the equipment.
4.6.2 Requirement for the detection of a failure of periodic communication

A failure of periodic communication shall be detected for any type of device within the time periods as

specified in EN 50131-1:2006, subclause relating to Verification of periodic communication. In the case of a

failure of communication to and from a WD or to and from an SPT, the annunciation of the failure shall be

processed (optional for grade 1 and grade 2).

In the event of a failure of periodic communication, a fault or tamper shall be generated in accordance with

EN 50131-1, clause relating to Signals and messages to be generated.
NOTE This requirement does not apply to portable devices (e.g. key fob).
4.6.3 Requirement for periodic communication before setting

Setting shall be prevented in accordance with EN 50131-1, clause relating to Verification during setting

procedure.

These requirements do not apply to wire-free ACE (e.g. keyfob or portable remote control).

4.6.4 Requirement for the detection of interference

If the level of modulated interference is great enough to corrupt the correct transmissions between

equipments, detection of interference shall take place when such levels are detected for time periods as

specified in Table 5.
Table 5 — Detection of interference timings
Detection of interference (maximum)
Grades 1 and 2 Sum total of 30 s of interference signal in any 60 s
Grades 3 and 4 Sum total of 10 s of interference signal in any 20 s
For all grades, when modulated interference with:

— a level equal to IL (IL is defined in 5.6.3) permanently applied, no indication or notification other than

those specified in EN 50131-1, clause relating to signals or messages to be generated, shall take place;

and

— a level as given in Table 7 and a duration less than 5 s, no indication or notification shall take place.

In the event of detection of modulated interference with a level as given in Table 7 and duration as given in

Table 5, a fault or tamper shall be generated for grade 1 and grade 2 equipment and a tamper shall be

generated for grade 3 and grade 4 equipment.

The requirements given in Table 5 do not apply to wire-free ACE (e.g. key fob or portable remote control).

According to the grade of the system, the following requirements given in Table 6 for interference detection

apply.
