The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to emit microwave radiation and analyse signals that are returned and to provide the necessary range of signals or messages to be used by the rest of the intrusion alarm system.

Other types of detector are covered by other documents identified as in EN 50131-2 series. 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.
