Introduction
This Technical Specification is a specification for passive infrared 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 a detector is to detect the broad spectrum infrared radiation emitted by an intruder
and to provide the necessary range of signals or messages to be used by the rest of the intruder
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 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 detectors, and uses 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.
