Introduction
This Technical Specification deals with Active Laser Detector Responsive to Diffuse Reflection (to be
referred to as ALDDR) installed inside buildings, used as part of intrusion alarm systems. It includes
four security grades and four environmental classes.
The purpose of an ALDDR is to detect an intruder inside a predefined area and to provide the
necessary range of signals or messages to be used by the rest of the intrusion alarm system.
The number and scope of these signals or messages will be more comprehensive for systems that are
specified at the higher grades.
This Technical Specification is only concerned with the requirements and tests for the ALDDR. Other
types of detectors are covered by other documents identified as in EN 50131-2 series.
1 Scope
This Technical Specification is for ALDDR inside buildings and provides four security grades 1 to 4
(see EN 50131-1), specific or non-specific wire or wire-free ALDDR, and uses environmental classes I
to IV (see EN 50130-5).
An ALDDR fulfils all the requirements of the specified grade.
The ALDDR detects an intruder inside a predefined area.
This standard covers ALDDR using both pulsed and continuous wave laser operation technologies
according to LIDAR principle (Light Detection And Ranging). Other technologies i.e. doppler based
laser operation or use of additional retro-reflective objects or video based technologies are not
covered by this standard.
Functions additional to the mandatory functions specified in this standard may be included in the
ALDDR, providing they do not adversely influence the correct operation of the mandatory functions.
This Technical Specification does not apply to system interconnections.
This Technical Specification does not deal with requirements for compliance with regulatory directives,
such as EMC-directive, low-voltage directive, etc., except that it specifies the equipment operating
conditions for EMC- susceptibility testing as required by EN 50130-4.

Alternatively total loss of power supply shall be determined by loss of
communication with the detector.
NOTE 1 This permits two methods of signalling a masking or reduction of range
event: either by the intrusion signal and fault signal, or by a dedicated masking or
reduction of range signal or message. Use of the intrusion signal and fault signal is
preferable, as this requires fewer connections between CIE and detector. If multiple
events overlap there will be some signal combinations that may be ambiguous. To
overcome this ambiguity it is suggested that detectors should not signal ‘intrusion‘ and
‘fault‘ at the same time except to indicate masking. This implies that the detector
should prioritize signals, e.g. 1 Intrusion, 2 Fault, 3 Masking.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages,
they shall be as shown in this table.
4.2 Detection
4.2.1 Detection performance
The ALDDR shall detect an intruder or an object inside a pre-defined area which is present for the
duration time as described in Table 3.
Table 3 — Interruption time limits
Test Grade 1 Grade 2 Grade 3 Grade 4
a
interruption time 200 ms 150 ms 100 ms 25 ms
Response probability 90 % 90 % 100 % 100 %
a
To avoid false alarms ≤ 10ms interruption time should not cause an alarm signal.
For the walk test the performance criteria of Table 7 shall be met.
4.2.2 Target object diameters
The manufacturer should claim the type of surveillance. Depending on the type of surveillance a signal
shall be generated, if the area surveyed by the ALDDR has been penetrated as follows:
– dive-through surveillance; penetration of a circular area with a diameter = 300 mm;
– reach-through surveillance; penetration of a circular area with a diameter = 40 mm.
After definition of the type of surveillance the manufacturer claim the maximum distance for each
surveillance type.
4.2.3 Detection of mirror
The ALDDR shall generate an intrusion signal or message if a mirror is placed within the detection
plane.
4.2.4 Indication of detection
A visual or acoustical indicator shall be provided on the ALDDR to indicate during walk test to show
that an intrusion signal or message has been generated. This indicator shall only be enabled during
walk test.
At grade 1 this indicator shall be capable of being enabled and disabled either remotely at Access
Level 2 and/or locally after removal of a cover which provides tamper detection as described in Tables
1 and 4. At grades 2, 3 and 4 this indicator shall be capable of being enabled and disabled remotely at
Access Level 2.
4.2.5 Significant reduction of range
Grade 4 detectors shall detect significant reduction of range, for example, to deliberate or accidental
introduction of objects or obstructions into the coverage area.
Range reduction of more than 50 % and duration longer than 1 s shall generate a signal or message
within 180 s, according to the requirements of Table 1 and Table 2.
4.2.6 Masking
Means shall be provided to detect inhibition of the operation of the detector by masking according to
the requirements of Table 1.
In any I&HAS, any masked detectors should prevent setting of the system.
The maximum response time for the masking detection device shall be 180 s. Masking shall be
signalled according to the requirements of Table 2. The signals or messages shall remain for at least
as long as the masking condition is present. A masking signal or message shall not be reset while the
masking condition is still present. Alternatively, the masking signal or message shall be generated
again within 180 s of being reset if the masking condition is still present.
NOTE From a system design point of view it would be preferable for masked detectors to automatically reset
after the masking condition is removed.
No masking signal or message shall be generated by normal human movement according to
Figure G.4.
For detectors where detection of masking may be remotely disabled the detection of masking shall
operate when the I&HAS is unset; it is not required to operate when the I&HAS is set.
4.3 Operational requirements
4.3.1 Time interval between intrusion signals or messages
ALDDR using wired interconnections shall be able to provide an intrusion signal or message not more
than 15 s after the end of the preceding intrusion signal or message.
ALDDR using wire-free interconnections shall be able to provide an intrusion signal or message after
the end of the preceding intrusion signal or message within the following times:
Grade 1 300 s
Grade 2 180 s
Grade 3 30 s
Grade 4 15 s
4.3.2 Switch on delay
The ALDDR shall meet all functional requirements within 180 s of the power supply reaching its
nominal voltage as specified by the manufacturer.
4.3.3 Self-tests
The ALDDR shall automatically test itself at least once every 24 h according to the requirements of
Tables 1 and 2. If normal operation of the ALDDR is inhibited during a local self-test, the ALDDR
inhibition time shall be limited to a maximum of 30 s in any period of 2 h.
An ALDDR shall process remote self-tests and generate signals or messages in accordance with
Tables 1 and 2 within 10 s of the remote self-test signal being received, and shall return to normal
operation within 30 s of the remote test signal being received.
4.4 Immunity to incorrect operation
4.4.1 General
The ALDDR shall be considered to have sufficient immunity to incorrect operation if the following
requirements have been met. No intrusion signal or message shall be generated during the tests.
4.4.2 Immunity to ambient visible and near infrared radiation
The ALDDR shall not generate any signal or message when a car headlamp is swept across the front
window or lens through a glass-pane.
4.4.3 Immunity to ALDDR´s of the same type
The ALDDR shall not generate any signal or message when a device of the same type (ALDDR) is in
the field of view of the ALDDR.
4.4.4 Immunity to small fast moving objects
The ALDDR shall not generate any signal or message if small fast objects pass through the detection
plane(s).

6.2 Basic detection test
6.2.1 General
The purpose of the basic detection test is to verify that an ALDDR is still operational after a test or
tests has/have been carried out. The basic detection test verifies only the qualitative performance of
an ALDDR. The basic detection test is performed using the BDT.
6.2.2 Basic detection target (BDT)
The following test shall be driven according to the detection characteristic (e.g. reach through
detection), the manufacturer of the ALDDR has specified in the technical documentation. For this
purpose, the ALDDR will be set up according to the manufacturer's instructions. During the test the
output is monitored for alarm signals and / or messages.
For the test, a pipe covered with black material with the length of 1m and the diameter of 300 mm is
used, the material shall be according to the technical specification see Annex H.
6.2.3 Basic test of detection capability
The BDT should be positioned within the detection area for a minimum of 5 s and at a distance of 5 m
or the maximum specified distance by the manufacturer for 10 times. The minimum time between each
test is 5 s.
Pass/Fail Criteria: The test is passed if the ALDDR does generate an intrusion signal or message
which is equal to or higher than the response probability given in Table 3 for the total number of tests
performed.
6.3 Performance testing
6.3.1 Velocity test method
Switch on the ALDDR power with the indicator enabled.
The ALDDR shall detect the interruption of the beam(s) within the time limits as described in Table 3
and generate an alarm signal or message.
The test is performed by a free falling cylinder object with the dimensions described in Annex A and
the black and reflective material described in Annex H.
Detection times as in 4.2.1 (Table 3). The diameters are to be chosen depending on the claimed
diving through / reach through application scenario.
The detection tests will be performed at the maximum claimed range by the manufacturer.
The minimum time between each test is 5 s. The test shall be performed 10 times for the interruption
time depending on the grade described in Table 3.
Pass/Fail Criteria: For the interruption time (specified in Table 3) the test is passed if the ALDDR does
generate an intrusion signal or message with a probability which is equal to or higher than the
response probability given in Table 3 when an interruption of a time period as specified in Table 3
occurs.
6.3.2 Walk test method
6.3.2.1 General
Walk testing is accomplished by the controlled movement of a SWT across the field of view of the
detector. The grade dependent velocities and attitudes to be used by the SWT are specified in
Table 3. The SWT begins and ends a walk with feet together. Annex G is an informative description of
two systems that may be used to control and monitor the desired velocity. Annex F is describing how
to measure these velocities and the sequences.

6.3.2.2 General walk test method
Walk testing is accomplished by the controlled movement of a SWT across the field of view of the
detector. The grade dependent velocities and attitudes to be used by the SWT are specified in
Table 7. The distance tolerances (offset) are according to the manufacturers claimed values. The SWT
begins and ends a walk with feet together. Annex F is an informative description of two systems that
may be used to control and monitor the desired velocity.
6.3.2.3 Standard walk test target
The SWT shall have the physical dimensions of 1,60 m to 1,85 m in height, shall weigh 70 kg ± 10 kg
and shall wear close-fitting clothing having a recommended light reflectivity of at least 10 %.
6.3.2.4 Verification of detection performance
The general test conditions of 6.1.1, 6.1.2 and 6.1.3 shall apply to all tests in this series.
Detection performance shall be tested against the manufacturer’s documented claims.
Any variable controls shall be set to the values recommended by the manufacturer to achieve the
claimed performance.
If the dimensions of the detection pattern exceed the available test space, it may be tested in sections
rather than as a whole.
6.3.2.5 Detection across and within the detection boundary
6.3.2.5.1 General
The tests assess detection of intruders moving within and across the boundaries of the detection area.
The diagrams in Annex G show an example of the detection boundary superimposed where
appropriate upon a scaled 2 m squared grid. A variety of boundary formats is possible and can be
tested according to the manufacturer s manual.
6.3.2.5.2 Verify detection across the boundary
Figure G.1 shows an example of a manufacturer’s claimed detection boundary.
Place test points at 2 m intervals around the boundary of the detection pattern, starting from the
detector, and finishing where the boundary crosses the detector axis. Repeat for the opposite side of
the detection pattern. If the gap between the final point on each side is greater than 2 m, place a test
point where the boundary crosses the detector axis.
A walk test is a walk in one direction through a test point either from out to inside or vice a versa.
Before commencing and after completing each walk test the SWT shall stand still for at least 20 s. The
start and end point should be at least 1,5 m away from the test point.
A walk test that generates an intrusion signal or message is a passed walk test.
Pass/Fail criteria: There shall be a passed walk test for every test point. If the first walk test attempt
does not generate an intrusion signal or message then four further attempts shall be carried out. All of
these further attempts shall generate an intrusion signal or message to constitute a passed walk test.
6.3.2.5.3 Detection within the boundary
Figure G.2 shows an example of a manufacturer’s claimed detection boundary superimposed upon a
scaled 2 m squared grid.
Starting at the detector, place the first test point at the manufacturer’s claimed minimum distance
along the detector axis. Using the 2 m squared grid, place further test points at every alternate grid
intersection, on both sides of the detector axis. No test point shall be less than 0,5 m from, or lie
outside, the claimed boundary.
Walk to each test point and stand still for 5 s.
A continuous intrusion signal or message shall be generated while the test sequence is performed.
Pass/Fail criteria: At each test point the detector shall generate an alarm signal or message or remain
in the alarm condition. If any test point does not generate an intrusion signal or message or fails to
remain in the alarm condition, then a further four attempts shall be carried out. All of these further
attempts shall generate an intrusion signal or message or the detector shall remain in the alarm
condition to constitute a passed test.
6.3.3 Non-Detection outside the boundary
Figure G.3 shows an example of a manufacturer’s claimed detection boundary.
Place test points from the defined boundary specified in 6.3.2.1 at 2 m intervals at a distance of 0,5 m
outside the boundary (surveyed area) of the detection pattern.
A walk test is a walk outside the boundary in minimum distance of 0,5 m from the defined boundary.
Before commencing and after completing each walk test the SWT shall stand still for at least 20 s.
Pass/Fail criteria: A walk test that generates no intrusion signal or message is a passed walk test.
Alternatively if the first walk test attempt does generate an intrusion signal or message then four
further attempts shall be carried out. All of these further attempts shall generate no intrusion signal or
message to constitute a passed walk test.
6.3.4 Detection of mirror
For Grade 4 ALDDR a mirror should be introduced at 50 % of the distance between ALDDR and the
BDT. The introduction of the mirror shall be performed to generate the same distance between
ALDDR and the BDT or maximum operating distance. The size of the mirror shall be 1,80 by 1 m.
Pass/Fail Criteria: The test is passed if an intrusion signal is generated by the ALDDR.
6.4 ALDDR Switch-on behaviour
Place the basic detection test target within the detection field, switch on the ALDDR power with the
indicator enabled. Note the response.
After the specified time interval between signals carry out the basic detection test.
Pass/Fail Criteria: The ALDDR shall generate an intrusion signal or message latest in response to the
basic detection test.
6.5 Self-tests
According to the manufacturers definition confirm the self-test is being completed. Carry out the basic
detection test to verify that the ALDDR is operating.
Pass/Fail Criteria: The ALDDR shall generate an intrusion signal or message and shall not generate
tamper or fault signals or messages.
For grade 3 and 4 ALDDR’s, monitor the ALDDR during a local self-test.
Pass/Fail Criteria: The ALDDR shall not generate any intrusion, tamper or fault signals or messages.
For grade 4 ALDDR’s, monitor the ALDDR during a remote self-test. Note the response.
Pass/Fail Criteria: The ALDDR shall generate an intrusion signal or message and shall not generate
tamper or fault signals or messages.
Short the sensor signal output to ground or carry out an equivalent action as recommended by the
manufacturer. For grade 3 and 4 ALDDR’s, monitor the ALDDR during a local self-test. For grade 4
ALDDR’s, also monitor the ALDDR during a remote self-test. For ALDDR’s with more than one sensor
signal output, the test(s) shall be repeated for each output individually.
Pass/Fail Criteria: (local self-test): The ALDDR shall generate a fault signal or message and shall not
generate intrusion or tamper signals or messages.
Pass/Fail Criteria: (remote self-test): The ALDDR shall generate a fault signal or message and shall
not generate intrusion or tamper signals or messages.
