Alarm systems. Intrusion and hold-up systems - Requirements for combined passive infrared and microwave detectors Ingestion-build-58863 The principles of this document1 Scope This document is for combined passive infrared and microwave detectors installed in buildings and provides for security grades 1 to 4 (see EN 501311), specific or non specific wired or wire free detectors, and uses environmental classes I to IV (see EN 501305). This document does not include requirements for detectors intended for use outdoors. The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an
