Bridge alarm system
FURUNO’s Bridge Alarm System manages the onboard
equipment alarms and monitors watch officer’s
presence for early detection of emergency
The Bridge Alarm System BR-1000 collectively controls the
warning notice from equipment onboard and monitors watch
officer’s presence for maritime casualty avoidance. The
BR-1000 performs the following two functions: Bridge alarm
system and Watch safety system.
In the bridge alarm system function, the Bridge Panel of the
BR-1000 in the wheelhouse generates the visual and audible
alarms upon the equipment alarm’s activation. If the alarm is
not acknowledged at this stage, the BR-1000 will transmit the
alarm to the Cabin Panels in other sections of the vessel.
Also, the BR-1000 monitors the watch officer’s presence
through watch safety system function. A watch officer is
required to press any keys of the equipment or Timer Reset
Panel at certain intervals. When the officer fails to press the
key within pre-set intervals, the visual and audible alarms will
be generated in the wheelhouse. If the officer doesn’t
respond to the alarm, the BR-1000 transmits the alarm to the
Cabin Panels installed other sections of the vessels in order
to inform backup officers of the watch officer’s absence.
The BR-1000 offers 3 operation modes: One-man, Bridge
Attended and Harbour. In One-Man operation mode, both
bridge alarm system and watch safety system work. In
Bridge Attended mode, visual and audible alarm will be
generated in the wheelhouse, but the alarm will not
transferred to the Cabin Panels. In Harbour mode, visual
alarm will be activated only on the Bridge Panel in the
wheelhouse, not be transferred to the Cabin Panels.
The BR-1000 meets the IMO MSC. 128(75). The Processor
Unit has total of 48 ports to interface the equipment onboard
and watches their alarm status. It also has 7 ports for the
operator’s presence inputs. Watertight Timer Reset Panel
can also be selected (optional supply). Up to 14 Cabin
Panels can be installed on a ship.
