Gas alarm Transfer
In the event one BM 25W goes into a gas alarm, all secondary BM 25Ws will display «
Al. Transfert » as shown below. Press the “acquit” button to silence the audible alarm.
The BM 25W strobe will continue to flash until the alarm event has ended. The audible
alarm will reactivate after 5 minutes if the alarm event is still active.
Note that if a second BM 25W had to fire a gas alarm, then this BM 25W would pass
from ‘secondary’ to ‘main’ status and would sound at 1 or 2 Hz depending on the alarm
level being reached. The secondary BM 25Ws would not immediately reactivate the
local siren.

Fault Transfert
In the event one BM 25W goes into fault condition, secondary BM 25Ws will display on
their LCD screen the message « Def. Transfert » as shown below. This fault condition
is not acknowledgeable and is automatically cleared as soon as the main BM 25W
goes back into a normal operating condition.
