7、gnet listed below instead of the AlNiCo version described in Annex D and Figure D.1 for reproducible tests ? Interpretation: Yes, because this will allow stable and reproducible test results, which is not guaranteed while using the AlNiCo magnet due to the nature of the magnet material. Furthermore,
8、 the test magnet described below allows a high-level degree of backward compatibility for already tested products, while it gives the stability required. Therefore, when the NeoDym magnet is used for test purposes (for test houses and manufacturers), the text below may be used in place of Annex D. V
9、alidity: This interpretation remains valid until an amendment or updated standard dealing with this issue is published by CENELEC.

These tests will be performed wit
42、h the sizes and thicknesses of glass specified in Annex B. Additionally, tests will be performed with the minimum size claimed by the manufacturer, if it is smaller than the minimum size specified in Annex B. Additionally, tests will be performed with the thinnest glass claimed by the manufacturer,
43、if it is thinner than the minimum thickness specified in Annex B. 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 180 s. The intrusion signal or message output shall b
44、e 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 verify that a detector is still operational after a tes
45、t or tests has/have been carried out. The basic detection 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 device available which will simulate a glass breakage or dest
46、ruction, without breaking the glass (BTS), alternatively a pane of standard sized glass (see Annex B) can be broken to verify the detection. The Basic Test Source (BTS) which is specified by the manufacturer simulates the breaking of a standard glass window by the low energy attack test. The availab
47、le test device shall be based on recorded glass break sounds, from or recommended by the manufacturer. This device should be a glass break simulator which ensures reliable locating and testing of passive acoustic glass break detectors. The passive acoustic glass break simulator should generate plate
48、 or tempered glass sound samples. 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 instructions after the first installation, to verify
49、, that all detectors are installed properly. It will be performed again, 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 compare 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
