Alarm Transfer 

By connecting the output of a BM 25A to the input of another BM 25A, 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 
25As on a daisy chain or to monitor a tank by connecting the units in loop. 

Refer to the 

Connections paragraph on page 5 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 

41.
