Introduction
This Technical Specification is a specification for microwave detectors (to be referred to as the detector)
used as part of intrusion detection systems installed in buildings. It includes four security grades and the
first three environmental classes.

The purpose of the detector is to detect an intruder. It emits microwave radiation over the area being
protected, and analyses signals that are returned. An intrusion signal or message is generated when the
detector registers a positive indication of the presence of an intruder. The detector shall provide the
necessary range of signals or messages to be used by the rest of the intrusion detection system.

The number and scope of these signals or messages will be more comprehensive for systems that are
specified at the higher grades.

All detectors shall meet the requirements of the telecommunications standards for short-range devices
(SRDs).
This specification is only concerned with the requirements and tests for the microwave detector. Other
types of detector are covered by other documents identified as CLC/TS 50131-2-x.

The requirement in EN 50131-1 that detectors in grade 3 and 4 systems shall include a means to detect a
significant reduction in range may be met either by detectors having the appropriate function (4.2.3) or by
suitable system design.
1 Scope
This Technical Specification provides for security grades 1 to 4 (see EN 50131-1) specific or non-specific
wired or wire-free microwave detectors and is covered by environmental classes I to III (see EN 50130-5).

A function designated in the specification as not required for a particular grade may be provided by the
manufacturer. If provided, it will be tested, and shall meet all relevant requirements of any higher grade. If
it passes, the manufacturer may claim it as an extra feature, which does not alter the overall grading of the
detector.
The specification does not apply to system interconnections.

3 Definitions and abbreviations

For the purpose of this specification, the following definitions and abbreviations apply in addition to those
given in EN 50131-1:
3.1

human being or a standard target

3.2
basic detection target
microwave reflector designed to verify the operation of a detector

3.3
ceiling mount detector
detector capable of sensing human movement from a mounting position on the ceiling

3.4
incorrect operation
physical condition that causes an inappropriate signal from a detector

3.5
local memory
storage medium situated on board the detector, and having the capability to record signals or messages
generated by the detector
3.6
long range detector
detector capable of sensing human movement in an extended field of view with horizontal angular
coverage less than 10°
3.7
masking
interference with the detector input capability by the introduction of a physical barrier

3.8

an intruder
3.11
standby/unset mode

response to stimulation by a human being or a standard target

NOTE  For environmental reasons, the microwave emitter may be switched off.

3.12
test mode
state of operation in which a detector will activate an intrusion indicator in response to stimulation by a
human being or a standard walk test target

3.13

crawling attitude shall consist of the standard walk test target moving with hands and knees in contact with
the floor
3.16
walk test attitude, upright
upright attitude shall consist of the standard walk test target standing and walking with arms held at the
sides of the body. The standard walk test target begins and ends a traverse with feet together
