IEC 62642-2-72-2015 pdf download.Alarm systems – Intrusion and hold-up systems – Part 2-72: Intrusion detectors – Glass break detectors (passive).
This part of IEC 62642 defines passive surface mounted glass break detectors installed in buildings and provides for security grades 1 to 4 (see IEC 62642-1 ), specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV (see IEC 62599-1 ).
This International Standard does not include requirements for passive surface mounted glass break detectors intended for use outdoors. A detector complies with 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 adversely influence the correct operation of the mandatory functions. This International Standard does not apply to system interconnections.

3 Terms, definitions and abbreviations For the purposes of this document, the terms, definitions and abbreviations given in IEC 62642-1 , as well as the following apply.
3.1 Terms, definitions and abbreviations 3.1.1 glass breakage physical destruction of a glass pane, which allows intrusion to the monitored area, for example in doors, windows or enclosures
3.1.2 passive surface mounted glass break detector detector that is mounted on a glass pane, which detects the energy emitted by a glass breakage of the pane the detector is mounted on
3.1.3 basic test source signal simulator designed to verify the basic function of the detector
3.1.4 incorrect operation physical condition that causes an inappropriate signal or message from a detector
3.1.5 basic detection test test whose purpose is to verify the operation of a detector after conditioning
3.1.6 masking interference with the detector input capability such as an introduction of a physical barrier (e.g. metal, plastic, paper or sprayed paints or lacquers in close proximity to the detector) or changing the characteristics of the monitored area (e.g. placing wet newspapers on the outside of the monitored glass pane)
3.1 .7 standard immunity glass pane glass pane to be used for all immunity tests, where a glass pane is needed, according to Annex A
3.1.8 simultaneous installation installation of more then one detector or sensor pair of one detector type (e.g. sender and receiver) for one or more detector´s processing units 3.2 Abbreviations BTS Basic test source EMC Electromagnetic compatibility
