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.
