Introduction
This European Standard is for combined passive infrared and ultrasonic 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 a detector is to detect the broad spectrum infrared radiation emitted by an intruder
and, at the same time, to emit ultrasonic radiation over the area being protected, and analyse signals
that are returned, 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 European Standard is only concerned with the requirements and tests for the detector. Other
types of detector are covered by other documents identified as EN 50131-2 series.

1 Scope
This European Standard is for combined passive infrared and ultrasonic 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 standard does not
include requirements for combined passive infra red and ultrasonic detectors intended for use
outdoors.
A detector shall fulfil all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this standard may be included in the
detector, providing they do not influence the correct operation of the mandatory functions.
The European Standard does not apply to system interconnections.
