Introduction
This Technical Specification is a specification for combined passive infrared and microwave detectors (to
be referred to here as the combined 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 combined detector is to detect the broad spectrum infrared radiation emitted by an
intruder and, at the same time, to emit microwave radiation over the area being protected, and analyse
signals that are returned. An intrusion signal or message is only generated when both technologies
register a positive indication of the presence of an intruder, thus reducing incorrect operation. The
combined 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.
If a combined detector can be operated in each technology individually, it shall also meet the grade
dependent requirements of the standards having relevance to those technologies.
This specification is only concerned with the requirements and tests for the 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 combined passive infrared and 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.
