4.3.1.3 Performance test for hole drilling with a diamond hole saw
This test will verify the detection performance by drilling a hole using a diamond hole saw on different glass types and dimensions according to the supported conditions claimed by the manufacturer and Annex A. It will verify if the detector is able to identify and signal the change of the integrity of the monitored side of the glass pane.
4.3.1.4 Performance test for glass cutting
This test will verify the detection performance by cutting the glass using a standard glass cutter on different glass types and dimensions according to the supported conditions claimed by the manufacturer and Annex A. It will verify if the detector is able to identify and signal the change of the integrity of the monitored side of the glass pane.
4.3.2 Indication of detection
Powered detectors at grades 3 and 4 that include processing capabilities shall provide an indicator at the detector to indicate when an intrusion signal or message has been generated. Self-powered detectors (e.g. detectors which rely on the energy resulting from the glass breakage) do not require such an indicator.
At grades 3 and 4 this indicator shall be capable of being enabled and disabled remotely at access level 2.
4.4 Immunity to false alarm sources
4.4.1 General
The detector shall have sufficient immunity to false alarm sources if the following requirements have been met. No intrusion signal or message shall be generated as a result of the false alarm sources according to each individual test clause.
The tests for this clause will be performed on the standard immunity test glass pane as defined in 3.1.7, wherever a glass pane is required.
4.4.2 Immunity to small objects hitting the glass
The detector shall not generate an intrusion signal or message when small objects such as hail, sand, gravel etc. hit the outside of the monitored glass. The tests are described in 6.7.2.
4.4.3 Immunity to soft objects hitting the glass
The detector shall not generate an intrusion signal or message when soft objects (e.g. a human fist) hit the outside of the monitored glass. The tests are described in 6.7.3.
4.4.4 Immunity to hard objects hitting the glass
The detector shall not generate an intrusion signal or message when hard objects (e.g. handlebars of a bicycle) hit the outside of the monitored glass. The tests are described in 6.7.4.
4.4.5 Immunity to static pressure
The detector shall not generate an intrusion signal or message when permanent pressure changes applied to the monitored glass. The tests are described in 6.7.5.
4.4.6 Immunity to dynamic pressure
The detector shall not generate an intrusion signal or message when dynamic pressure
changes (due to wind, etc.) applied to the monitored glass. The tests are described in 6.7.6.
4.7.2 Immunity to environmental conditions All detectors shall meet the requirements of the relevant environmental class and equipment class as specified by the manufacturer of the environmental tests described in Table 6 and Table 7. These tests shall be performed in accordance with IEC 62599-1 and IEC 62599-2. Impact tests shall not be carried out on delicate detector components such as LEDs or microphones. Unless specified otherwise for operational tests, the detector shall not generate unintentional intrusion, tamper, fault or other signals or messages when subjected to the specified range of environmental conditions. For endurance tests, the detector shall continue to meet the requirements of this standard after being subjected to the specified range of environmental conditions.IEC 62642-2-72 pdf download.
