Alarm Transfer
By connecting the output of a BM 25 to the input of another BM 25, and so on, it is
possible to transfer alarms from instruments to instruments. This configuration is
particularly useful for perimeter monitoring. For example, it may be used to monitor a
fence by connecting the BM 25s on a daisy chain or to monitor a tank by connecting
the units in loop.
Refer to the Connections paragraph on page 14 for the wiring of the dry logic input or
the alarm relay output. The input and output can be configured using the COM 2100
software; see page 57.
