33、to 106 kPa 6.2.2 General detection testing environment and procedures Manufacturers documented instructions regarding mounting and operation shall be read and applied to all tests. 6.2.2.1 Testing environment The detectors or sensor elements will be mounted according to the manufacturers description
34、 on the monitored object (glass window or door glass pane). Some tests will be performed on the monitored object, others will be performed on panes (unframed window), where the detectors are mounted directly on. 6.2.2.2 Test procedures The tests will be performed with the types of glass claimed by t
35、he manufacturer. These tests will be performed with the sizes and thicknesses of glass as specified in Annex A. Additionally, tests will be performed with the maximum size claimed by the manufacturer if this is greater than the maximum size specified in Annex A. Additional test will be performed wit
36、h the thinnest glass claimed by the manufacturer, if this is thinner than the minimum thickness specified in Annex A. The detector shall be connected to the nominal supply voltage and connected to the monitoring system that is appropriate to the test. The detector shall be allowed to stabilise for 1
37、80 s. The intrusion signal or message output shall be monitored. If multiple sensitivity modes are available, any non-compliant modes shall be identified by the manufacturer. All compliant modes shall be tested. 6.3 Basic Detection Test 6.3.1 General The purpose of the Basic Detection Test is to ver
38、ify that a detector is still operational after a test or tests has/have been carried out. The Basic Detection Test verifies only the qualitative performance of the detector. The Basic Detection Test is performed using the BTS. 6.3.2 Basic Test Source For functional verification there shall be a devi
39、ce available which will simulate a glass breakage or destruction, without breaking the glass (BTS), alternatively a pane of standard sized glass (see Annex A) can be broken to verify the detection. The Basic Test Source (BTS) which is specified by the manufacturer simulates the breaking of a standar
40、d glass window by the low energy attack test. This device should be a test device, which is specified for testing through simulation of a glass break from or recommended by the manufacturer. This device should simulate a glass breakage or destruction, by pressing the device onto the monitored glass
41、and simulating a sound, frequency or condition, which needs to be detected. 6.3.3 Basic Detection Test Method The detector shall generate an intrusion signal or message when a test device (BTS) is used to simulate a glass breakage. The test will be performed according to the manufacturers instructio
42、ns after the first installation, to verify, that all detectors are installed properly. It will be performed again, BS EN 50131-2-7-3:2012Copyright European Committee for Electrotechnical Standardization Provided by IHS under license with CENELECNot for ResaleNo reproduction or networking permitted w
43、ithout license from IHS-,-,- 15 - EN 50131-2-7-3:2012 after or / and during the environmental tests under the same conditions the tests had been performed the first time, to verify that the detectors will still function the way, the manufacturer claims to support (e.g. detection range) and to compar
44、e this results with the results of the initial test. If the test is not compatible with the detector, use the manufacturers information to generate the correct algorithm. The detector(s) shall produce an intrusion signal or message when exposed to an alarm stimulus both before and after being subjec
45、ted to any test that may adversely affect its performance. 6.4 Performance tests 6.4.1 General The general test conditions of 6.2.2 shall apply to all tests in this series. Detection performance shall be tested against the manufacturers documented claims. Any variable controls shall be set to the va
46、lues recommended by the manufacturer to achieve the claimed performance. The detectors shall be assessed in the specified test environment. 6.4.2 Verification of detection performance 6.4.2.1 General All performance tests are based on physical destruction characteristics (e.g. the sound of breakage)
47、 of the size, thickness and types of glass claimed to be supported by the manufacturer including the standard glass types listed in Annex A, if claimed to be supported by the manufacturer. 6.4.2.2 Sensitivity performance test The test will be performed for each glass type claimed to be supported by
48、the manufacturer. Each glass pane will be positioned on top of the support / distance pieces, to ensure that the glass break signal can reach the detectors undampened. Three sender and receiver pairs (or combined sensor elements) shall be mounted according to the manufacturers installation instructions on the monito
