7、or test houses and manufacturers) to use the NeoDym magnet listed below instead of the AlNiCo version described in Annex C and Figure C.1 for reproducible tests ? Interpretation: Yes, because this will allow stable and reproducible test results, which is not guaranteed while using the AlNiCo magnet
8、due to the nature of the magnet material. Furthermore, 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 manufacture
9、rs), the text below may be used in place of Annex C. Validity: This interpretation remains valid until an amendment or updated standard dealing with this issue is published by CENELEC.

This permits two methods of signalling a masking event: either by the intrusion signal and fault signal, or
14、by a dedicated output. Use of the intrusion signal and fault signal is preferable, as this requires fewer connections between CIE and detector. If multiple events overlap there will be some signal combinations that may be ambiguous. To overcome this ambiguity it is suggested that detectors should no
15、t signal intrusion and fault at the same time except to indicate masking. This implies that the detector should prioritise signals, e.g. 1. Intrusion, 2. Fault, 3. Masking. When, in Table 1, an event may optionally generate signals or messages, they shall be as shown in this table. 9 BS EN 50131-2-7

The Basic Detection Test verifies only the qualitative performance of the detector. The Basic Detection Test is performed using the BTS. 6.3.2 Basi

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 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 us
