44 BM 25/25W
Instruction Manual
25Ws on the network and forces to a new identification. Similarly as above, BM 25Ws
(units E, F and G) form a second group.
IMPORTANT :
■
The two groups run independently and alarm or failure events from one group
cannot be transferred to the other group.
■
When the obstacle (the truck in our example) is gone, the communication between
E and D resumes automatically without the need to restart identification. The two
groups merge together to form only one group.
To start a new identification, keep pressing the « acquit » button for 3 seconds. The
display successively shows 3, 2, 1 then « confirm ». Release the « acquit » button and
press again.

NOTE :
■
When a new identification has started, communication errors are inhibited for one
minute.
■
Once the network healing is completed, it is possible that one or several BM 25Ws
remain isolated and stay in fault mode (case No. 1
– Table of alarms). To
acknowledge this failure, turn the unit off or disable the radio communication from
the maintenance menu.
Adding a new BM 25W to the network at a smart location overcomes the obstacle and
restores the communication between the two groups which then merge together. This
healing is automatic as long as BM 25W (unit H) belongs to the same network (same
'Channel' ID).
