It shall be used in conjunction with the other parts of the EN 50131 series that define the functional requirements of the equipment regardless of the type of interconnecti

45、Immunity to attenuation Due to the fact there may be changes in the passive environment after installation, it shall be possible to temporarily attenuate the RF link during installation or maintenance according to the values given in Table 1. The manufacturer shall specify the means used on its equi

47、high level of confidence in the transmissions of alarm and monitoring messages thus reducing the probability of equipment on the same system causing interference by design and possibly leading to loss or corruption of information. To keep the collision rate as small as possible, the following requir
48、ements given in Table 2 shall be fulfilled.
