Introduction
This document deals with microwave detectors (to be referred to as the detector) used as part of
intrusion alarm systems installed in buildings. It includes four security grades and four environmental
classes.
The purpose of the detector is to emit microwave signals and analyse the signals that are returned to
detect an intruder 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 version of the standard contains limited requirements for Grade 4 detectors. Future revisions of the
standard are expected to include enhanced requirements for Grade 4 detectors.
This document is only concerned with the requirements and tests for the detector. Other types of
detector are covered by other documents identified as in the EN 50131-2 series.
NOTE Each country has certain regulations in regards to which part of the microwave spectrum is allowed to
be used in this application. This information can be found in ERC recommendation 70-03.
1 Scope
This document is for microwave detectors installed in buildings and provides for security grades 1 to 4
(see EN 50131-1), specific or non-specific wired or wire-free detectors, and uses environmental classes
I to IV (see EN 50130-5). This document does not include requirements for detectors intended for use
outdoors.
The purpose of the detector is to emit microwave signals and analyse the signals that are returned to
detect an intruder and to provide the necessary range of signals or messages to be used by the rest of
the intrusion alarm system.
The grade-dependent requirements of this document apply and it is essential that a detector fulfils all
the requirements of the specified grade.
Functions additional to the mandatory functions specified in this document can be included in the
detector, providing they do not influence the correct operation of the mandatory functions.
Requirements for system interconnections are not included in this document.

This permits two methods of signalling a masking: either by the intrusion signal and fault signal, or by a
dedicated masking 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.
When, in Table 1, an event may optionally generate signals or messages, they shall be as shown in this
table.
a
An independent signal or message may be provided instead.
b
Total loss of Power Supply does not apply for message based detectors.
4.2 Detection
4.2.1 Detection performance
The detector shall generate an intrusion signal or message when the standard or simulated walk-test
target moves at velocities and attitudes specified in Table 3. For detection across the boundary the walk-
test distance shall be 1,5 m either side of the boundary. For test “Detection within the boundary” the
walk-test distance shall be 3,0 m.

For grade 3 and 4 detectors, the intermittent movement shall consist of the SWT walking 1 m at a velocity of
1,0 ms-1 then pausing for 5 s before continuing. The sequence shall be maintained until the SWT has traversed
through the entire detection area. This constitutes one walk test. The test shall be repeated in each of the

directions shown in Figure C.3.
The detection performance tests required for a detector will depend on the coverage angle claimed.
Therefore this document differentiates between detectors with coverage angles less than or equal to
180°, such as those typically used for wall mounted applications, and detectors with coverage angles of
360° detectors intended for ceiling mounting.
4.2.2 Indication of detection
An indicator shall be provided at the detector 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 enabled/disabled after removal of a cover which provides
tamper detection as described in Tables 1 and 4. At grades 3 and 4 this indicator shall be capable of
being enabled and disabled remotely at Access Level 2.
4.3 Operational requirements
4.3.1 Time interval between intrusion signals or messages
Detectors 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.
Detectors 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 detector 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
4.3.3.1 General
Self-tests shall detect failures of a critical function (e.g. unable to detect the reflected microwave signals)
and signal these situations according to Table 2. As a minimum a self-test shall detect failures of the
output of the sensing technology.
4.3.3.2 Local Self-Test
The detector shall automatically test itself at least once every 24 h according to the requirements of
Tables 1 and 2. If normal operation of the detector is inhibited during a local self-test, the detector
inhibition time shall be limited to a maximum of 30 s in any period of 2 h.
4.3.3.3 Remote Self-Test
A detector 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 detector 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 microwave signal interference by fluorescent lights
The microwave detector shall not initiate the generation of any signals or messages due to the operation
of a fluorescent light source mounted nearby.
4.5 Tamper security

4.5.2 Resistance to and detection of unauthorised access to components and means of
adjustment
All components, means of adjustment and access to mounting screws, which, when interfered with,
could adversely affect the operation of the detector, shall be located within the detector housing. Such
access shall require the use of an appropriate tool and depending on the grade as specified in Table 4
shall generate a tamper signal or message before access can be gained.
It shall not be possible to gain such access without generating a tamper signal or message or causing
visible damage.
4.5.3 Detection of removal from the mounting surface
A tamper signal or message shall be generated if the detector is removed from its mounting surface for
each claimed mounting type (e.g. wall, ceiling, corner, brackets) in accordance with Table 4.
The tamper detection mechanism shall not be defeated by the use of small tools as per the examples
in Annex F.
4.5.4 Resistance to, or detection of, re-orientation
Detectors mounted on adjustable mountings, shall resist or detect reorientation.
After the torque given in Table 4 has been applied and then removed from the detector it shall not have
rotated more than 5° from its original position. Alternatively, when the torque given in Table 4 has been
applied, a tamper signal or message shall be generated if the detector rotates by more than 5°.
4.5.5 Immunity to magnetic field interference
It shall not be possible to inhibit any signal or message with a magnet of grade dependence according
to Table 4. The magnet types shall be as described in Annex A.
4.5.6 Detection of masking
Means shall be provided to detect inhibition of the operation of the detector by masking according to the
requirements of Table 4.
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 C.5.
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.
4.6 Electrical requirements
4.6.1 General
The grade-dependencies appear in Table 5. These requirements do not apply to detectors having
internal Type C power supplies. For these detectors, refer to EN 50131-6.

6 Testing
6.1 General
The tests are intended to be primarily concerned with verifying the correct operation of the detector to
the specification provided by the manufacturer. All the test parameters specified shall carry a general
tolerance of ± 10 % unless otherwise stated. A list of tests appears as a general test matrix in Annex B.
6.2 General test conditions
6.2.1 Standard conditions for testing
The general atmospheric conditions in the measurement and tests laboratory shall be, unless stated
otherwise:
Temperature 15 °C to 35 °C
Relative humidity 25 % RH to 75 % RH
Air pressure 86 kPa to 106 kPa
All values are “inclusive values”.
6.2.2 General detection testing environment and procedures
Manufacturer’s documented instructions regarding mounting and operation shall be read and applied to
all tests.
6.2.3 Testing environment
The detection tests require an enclosed, unobstructed and draught-free area that enables testing of the
manufacturer’s claimed coverage pattern. The test area shall be large enough so as not to significantly
affect the microwave coverage pattern due to reflections.
Annex C provides example diagrams for the range of walk tests for one format of detection pattern and
similarly a 360° detection pattern. Many others are possible.
6.2.4 Mounting height
If the manufacturer claims different detection patterns for different mounting heights, each pattern shall
be tested at the specified height.
If the manufacturer claims one pattern for a range of mounting heights, the full pattern shall be tested at
the claimed nominal height. If no nominal is specified, the full pattern shall be tested at the midpoint of
the height range. For detectors with coverage angles less than or equal to 180° at the maximum
mounting height all test points closer than 4,0 m from the detector shall be tested and all test points at
maximum claimed range shall be tested. For detectors with a coverage angle of 360° all test points at
maximum claimed range shall be tested. At the minimum mounting height all test points at maximum
claimed range shall be tested.
The mounting heights apply to walk tests only and not for any other tests, e.g. EMC and environmental.
6.2.5 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. No metallic objects shall be worn or carried by the SWT or incorrect
microwave reflection will result.
There shall be a means of calibration and control of the desired velocity at which the SWT is required
to move.
The use of a simulator/robot in place of the SWT is permitted, provided that it meets the specification of
the SWT with regard to microwave reflectivity. It is known as the simulated target. In case of conflict, a
human walk test shall be the primary reference.
6.2.6 Testing procedures
The detector shall be connected to the nominal supply voltage, and connected to equipment with a
means of monitoring intrusion signals or messages. The detector shall be allowed to stabilize for 180 s.
Any non-compliant detection settings shall be identified by the manufacturer and not subject to testing.
All tests will be performed at the most sensitive setting (e.g. high sensitivity, maximum range) unless
otherwise stated.
6.3 Basic detection test
6.3.1 General
The purpose of the basic detection test is to verify that a detector is still operational after a test or tests
has/have been carried out. The basic detection test verifies only the qualitative performance of a
detector. The basic detection test is performed using the BDT(s).
6.3.2 Basic detection targets (BDT)
The BDT is a human hand, alternatively the BDT consists of a metal plate having equivalent microwave
reflectivity to that of the human hand, which can be moved across the field of view of the detector.
A short range walk test may be carried out as an alternative to using the BDT.
6.3.3 Basic Detection Test procedure
A stimulus that is similar to that produced by the SWT using the BDT is applied to the detector. Move
the BDT perpendicularly across the centre line of the detection field at a distance of not more than 1 m,
and at a height where the manufacturer claims detection will occur.
−1 −1
Move the BDT along a distance of 1 m at a velocity of 0,5 ms to 1,0 ms . The detector shall produce
an intrusion signal or message when exposed to an alarm stimulus both before and after being subjected
to any test that may adversely affect its performance.
Pass/Fail Criteria: The detector shall generate an intrusion signal or message and shall not generate
tamper or fault signals or messages.
6.4 Walk testing
6.4.1 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 requirements including velocities and attitudes to be used by the SWT
are specified in Table 3. The tolerance of these velocities shall be better than ± 10 %. The SWT begins
and ends a walk with feet together. Annex D is an informative description of two systems that may be
used to control and monitor the desired velocity.
The detector shall be mounted at a height according to 6.2.4. The orientation shall be as specified by
the manufacturer with unobstructed view of the walk test to be performed.
When the detector is walk tested, it shall be set to the least sensitive setting required to achieve the
claimed compliant detection coverage (e.g. lowest sensitivity setting).
Before commencing and after completing each walk test, the SWT shall stand still for at least 20 s.
The walk test attitude, crawling, is a crawling attitude which shall consist of the standard walk test target
moving with hands and knees in contact with the floor.
The walk test attitude, upright, is an upright attitude which shall consist of the standard walk test target
standing and walking with arms held at the sides of the body.
6.4.2 Verification of detection performance
The general test conditions of 6.2 shall apply to all tests in this series.
Detection performance shall be tested against the manufacturer’s documented claims. The
manufacturer shall provide the test laboratory with scaled drawings of the claimed detection boundary
superimposed on a 2,0 m grid, see Annex C, Figure C.6. The manufacturer shall declare the detector
reference axis.
Care should be taken when defining the claimed detection boundary as inaccuracy in the boundary may
result in test failure.
Example walk test diagrams are shown in Annex C.
It is recommended that the test laboratory mark on the scaled drawings, the locations of the test points
as determined by the following procedures for reference during the walk testing. Detection settings shall
be set to the values recommended by the manufacturer to achieve the claimed performance.
Preferably the detection coverage will be tested as a whole, however if the dimensions of the detection
pattern exceed the available test space, it is permitted to test the detection performance in sections,
provided the performance of the microwave technology is not influenced by the close proximity to walls
or other objects.
For example, detectors with a coverage angle of 360° can be tested in sections where it is permitted to
rotate the detector in order to test the complete coverage pattern as described in the corresponding
procedures for the tests. If this method is used, sufficient clearance shall be provided when mounting
close to a wall or other structure, to allow adequate space for the tests to be performed unimpeded.
If a detector has been tested in sections, the method shall be described in the test report.
The SWT or a suitable simulated target shall be used. Grade dependent velocities and attitudes are
specified in Table 3.
6.4.3 Detection across and within the detection boundary
6.4.3.1 General
The tests assess the ability to detect intruders moving within and across the boundaries of the detection
area.
6.4.3.2 Verify detection across the boundary for detectors with coverage angles less than or
equal to 180°
Figure C.1 a) shows an example of a manufacturer’s claimed detection boundary for a detector with a
coverage angle less than 180°.
Place test points at 2,0 m intervals (measured in straight-line distances) around the claimed detection
boundary of the detector, starting from the detector, and finishing where the claimed detection boundary
crosses the detector reference axis. Repeat for the opposite side of the detection pattern. If the gap
between the final point on each side is greater than 2,0 m, place a test point where the claimed detection
boundary crosses the detector axis. For Grade 1 detectors it is only necessary to test alternate test
points.
Each test point is connected to the detector by a radial line. At each test point, two test directions into
the detection coverage pattern are available at +45° and −45° to the radial line. Both directions shall be
tested beginning at a distance of 1,5 m from the test point, and finish 1,5 m after it. If the placement of
the test point results in one of the test directions being outside the claimed detection boundary, this
direction shall be rotated 180° such that the SWT enters the coverage pattern. An example of a test
point direction that shall be rotated is shown at the location labelled A of Figure C.1 a). Similarly, the
directions of the next three adjacent test points are also rotated.
A walk test is a walk in one direction through a test point.
A walk test that generates an intrusion signal or message is a passed walk test.
Pass / Fail Criteria: An intrusion signal or message shall be generated in response to the first walk test.
Alternatively 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.
6.4.3.3 Verify detection across the boundary for detectors with a coverage angle of greater
than 180°
Figure C.1 b) shows an example of a manufacturer’s claimed detection boundary for a detector with
360° coverage angle. Place test points at 2,0 m intervals (measured in straight-line distances) around
the claimed detection boundary of the coverage pattern, starting from the point where the claimed
detection boundary crosses the detector reference axis and working in a clockwise direction until either
the detector or the first test point is reached. For Grade 1 detectors it is only necessary to test alternate
test points.
At each test point, two test directions into the detection coverage pattern are available at +45° and −45°
to the radial line. Both directions shall be tested beginning at a distance of 1,5 m from the test point, and
finish 1,5 m after it.
A walk test is a walk in one direction through a test point.
If the detection performance is tested in sections (e.g. four sections of 90°), this shall be equivalent to
the detection performance when tested in one section. The test points shall fall on the same points
around the circumference as if the test was done in 360°.
Pass / Fail Criteria: An intrusion signal or message shall be generated in response to the first walk test.
Alternatively, 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.
6.4.3.4 Verify detection within the boundary for detectors with coverage angles less than or
equal to 180°
Figure C.2 a) shows an example of a manufacturer’s claimed detection boundary for a detector with a
coverage angle less than 180°.
Starting at the detector, place the first test point at 4,0 m along the detector reference axis. Using the
2,0 m squared grid, place further test points at alternate grid intersections within the claimed detection
boundary as shown in the Figure C.2 a). Test points located 1 m or less from a claimed detection
boundary test point (as determined in 6.4.3.2) can be omitted.
Each test point is connected to the detector by a radial line. At each test point, two test directions are
available, at +45° and −45° to the radial line. Both directions shall be tested beginning at a distance of
1,5 m from the test point, and finish 1,5 m after it.
A walk test is a walk in one direction through a test point
Pass / Fail Criteria: An intrusion signal or message shall be generated in response to the first walk test.
Alternatively, 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.
6.4.3.5 Verify detection within the boundary for detectors with coverage angle of greater
than 180°
Figure C.2 b) shows an example of a manufacturer’s claimed detection boundary for a detector with
360° coverage angle.
Starting at the detector, place the first two test points at 2,0 m along the detector reference axis on both
sides of the detector. Refer to 1 and 2 of Figure C.2 b). Draw lines from each initial test point with an
angle of +45° and −45° from the detectors reference axis. Where the lines intersect, two more test points
will be placed. Refer to 3 and 4 of Figure C.2 b).
Using the 2,0 m squared grid, place further test points at alternate grid intersections within the claimed
detection boundary. Test points that fall outside of the claimed detection boundary or are located 1 m or
less from a claimed detection boundary test point (as determined in 6.4.3.3) can be omitted.
Each test point is connected to the detector by a radial line. At each test point, two test directions are
available, at + 45° and – 45° to the radial line. Both directions shall be tested beginning at a distance of
1,5 m from the test point, and finish 1,5 m after it.
A walk test is a walk in one direction through a test point.
