Introduction
The purpose of an Active Infrared Beam Detector (AIBD) is to detect an intruder interrupting one or
more infrared beam(s) and to provide the necessary range of signals or messages to be used by the
rest of the intrusion alarm system. The AIBD consists of a transmitter, sending out infrared radiation,
and a receiver, which detects the interruption of the received radiation. The infrared radiation sent out
by the transmitter can reach the receiver over a reflector.
The number and scope of these signals or messages will be more comprehensive for systems that are
specified at higher Grades.
This Technical Specification is only concerned with the requirements and tests for the AIBDs. Other
types of detectors are covered by other documents identified as in the EN 50131-2 series.
1 Scope
This Technical Specification is applicable to Active Infrared Beam Detectors (AIBDs) installed inside
buildings and used as part of intrusion alarm systems.
It specifies four security Grades 1 to 4 (in accordance with EN 50131-1) and uses environmental
Classes I to IV (in accordance with EN 50130-5).
This standard covers only AIBDs using interruption based technology. Other technologies i.e. Doppler
based technology are not covered by this document.
Functions additional to the mandatory functions specified in this document can be included in the
AIBD, providing they do not adversely influence the correct operation of the mandatory functions.
This document does not apply to system interconnections.

4.3 Detection
4.3.1 Detection performance
The AIBD shall detect the interruption of the beam(s) within the time limits as described in Table 3.
The AIBD shall not generate an alarm signal or message if the interruption of the beam is equal to or
less than the minimum detected interruption time given in Table 3, in accordance with the probability
shown. The AIBD shall generate an alarm signal or message, in accordance with the probability
shown, if the interruption of the beam is for more than the maximum undetected interruption time given
in Table 3. The generation of an alarm signal or message is optional for interruptions of duration
between the minimum and maximum interruption times.
Table 3 — Interruption time limits

4.3.2 Indication of detection
An indicator, e.g. LED, shall be provided on the AIBD to indicate when an intrusion signal or message
has been generated. At Grades 1 and 2 this indicator shall be capable of being enabled and disabled
either remotely at Access Level 2 and/or locally after removal of cover which provides tamper

Level 2.
4.3.3 Planar detection characteristic
This sub clause applies to one way multiple beam and two way multiple beam only.
With multiple beam devices it is possible to supervise planar areas. Depending on the type of

output is monitored for alarm signals or messages.
The BDTT shall be placed into the detection area halfway along the detection area and remain for at
least 2 s.
For one way AIBDs the test shall be performed equidistant between transmitter and receiver.
For two way AIBDs the test shall be performed equidistant between transceiver and reflector.
Pass/Fail Criteria: The AIBD passes the test if it detects the interruption.

tamper or fault signals or messages.

Pass/Fail Criteria: The AIBD shall not generate any intrusion, tamper or fault signals or
messages.
For Grade 4 AIBDs, also monitor the AIBD during a remote self-test.
Pass/Fail Criteria: The AIBD shall generate an intrusion signal or message and shall not generate
tamper or fault signals or messages.
— Prevent the normal operation of the AIBD according to the manufacturer’s recommendation. For
Grade 3 and 4 AIBDs, monitor the AIBD during a local self-test. For AIBDs with more than one
sensor signal output, the test shall be repeated for each output individually
Pass/Fail Criteria: The AIBD shall generate a fault signal or message and shall not generate
intrusion or tamper signals or messages.
For Grade 4 AIBDs, also monitor the AIBD during a remote self-test. For AIBDs with more than
one sensor signal output, the test shall be repeated for each output individually.
Pass/Fail Criteria: The AIBD shall generate a fault signal or message and shall not generate
intrusion or tamper signals or messages.
6.7 Immunity to incorrect operation
6.7.1 Immunity to the attenuation of the received signal
Switch on the AIBD power with the indicator enabled.
The AIBD shall not detect the interruption of the beam(s) if the signal emitted by the transmitter is
attenuated 75 % or less.
The test is performed by using an infrared-filter with an attenuation of 75 % (transmission of 25 %) of
the infrared-signal in the wavelength of the transmitted infrared-signal.
The transmitter and receiver for one way AIBDs and the transceiver and reflector for two way AIBDs
shall be placed at a distance of 5 m.
The filter shall be introduced in front of the transmitter optic.
Pass/Fail Criteria: The AIBD shall not generate an intrusion signal or message and shall not generate
tamper or fault signals or messages.
6.7.2 Immunity to air flow
From a point 1,0 m below and 1,0 m in front of the receiver of the AIBD (for one way AIBDs) or the
transceiver of the AIBD (for two way AIBDs), direct the airflow from a fan heater over the face of the
AIBD with the angle (α) of 12° to the ground. The warm air shall flow at a mean velocity of
−1 −1
0,7 ms ± 0,1 ms , measured at the receiver window.
NOTE In the case of a fan heater output with a typical size of 55 mm x 180 mm, that means a velocity
−1
of 2,2 ms .
Do not allow the receiver a direct view of the heating elements (refer to Annex C).
Begin at an ambient temperature of +20 °C and switch on the heater for 60 s. Switch off the fan heater
for 5 s and switch on the fan heater for 5 s. Repeat the cycle 10 times.
Run the basic detection test once during the air flow test, to ensure that the AIBD is not blocked by the
air flow.
Pass/Fail Criteria: There shall be no change of status of the AIBD. There shall be an intrusion signal or
message generated by the basic detection test.
6.7.3 Immunity to ambient visible and near infrared radiation

or lens) connected to a 13,5 V DC power supply, capable of generating at least 6 500 lx at a 2 m
range is used to illuminate the receiver or transceiver of the AIBD.
The lamp shall be burned in for 10 h and shall be discarded after 100 h use.
The light from the source shall fall on the receiver or transceiver of the AIBD through two clean 4 mm
thick panes of glass, separated by a 10 mm air gap, and placed at 0,5 m in front of the receiver or
transceiver of the AIBD.
Measure the light intensity at the receiver or transceiver of the AIBD with a calibrated visible light
meter.
Mount the receiver or transceiver of the AIBD in a darkened room at an initial range of 2 m from the
source. The source shall be mounted at an angle of 12° to the detection path of the AIBD. Mount the
visible light meter at the chosen position of the receiver or transceiver of the AIBD, and move the light
source towards and away from it until a reading in the visible band of 6 500 lx ± 10 % is obtained.
The light source shall be switched on for 30 s and switched off for 30 s five times.
Pass/Fail Criteria: There shall be no change of status of the AIBD.
