Gas alarm Transfer
In the event one BM 25AW goes into a gas alarm, all secondary BM 25AWs will display
« Al. Transfert » as shown below. Press the “acquit” button to silence the audible
alarm. The BM 25AW 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 25AW had to fire a gas alarm, then this BM 25AW 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 25AWs would not immediately reactivate the
local siren.

Fault Transfert
In the event one BM 25AW goes into fault condition, secondary BM 25AWs 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
25AW goes back into a normal operating condition.
