3.6 Alarm transfer from other navigational equipment
When this system is received an alarm signal from other navigational equipment such as radar
and ECDIS, further in case its acknowledgment (ACK) operation is not performed in the specified
time, its alarm is transferred to a 2nd and a 3rd stage remote audible alarms.
Since transfer of alarms are requires connections and settings to other navigational equipment,
request to Japan Radio Co., Ltd (JRC) sales department, a nearby branch office, business office,
or JRC agent.
3.6.1 Outline
The following are explanation for the outline of the alarm transfer. The each number of " )" for the
following items corresponds with the one in the right figure.
1) If an alarm is activated with other navigational
equipment, the alarm signal is transmitted to the
BNWAS.
2) An alarm (buzzer sound) sounds from the reset
button units / reset button unit (waterproof) of
BNWAS.
3) When a confirmation (ACK) operation is
performed with the navigational equipment, an
ACK signal is transmitted to the BNWAS.
4) When BNWAS receives the ACK signal of the
navigational equipment, the buzzer sound is
stopped, and it is not transferred to a 2nd and a
3rd stage remote audible alarms.
5) When the buzzer sound stopping operation is
performed by the BNWAS, the sound of the
BNWAS is stopped. Select ALARM->BRIDGE
ALARM from MENU, alarm contents are displayed on the LCD screen. Check the alarm then
the ACK signal is sent to the navigational equipment. Since the alarm has been confirmed, it is
not transferred to a 2nd and a 3rd stage remote audible alarms.
6) When the ACK operation is not performed with the BNWAS or the navigation equipment, and
in case its time has reached to the bridge alarm transfer delay time, it is transferred to a 2nd
stage remote audible alarm.
7) When the buzzer stopping operation is performed while the 2nd stage remote audible alarm is
sounding, the buzzer sound in the bridge and the 2nd stage remote audible alarms are
stopped. After the stop operation, in case the ACK operation is performed, it is not transferred
to a 3rd stage remote audible alarm.
8) After sounding the 2nd stage remote audible alarm, in case its time reaches to the 3rd stage
remote audible alarm transfer delay time without performed the ACK operation, it is
transferred to a 3rd stage remote audible alarm.
9) When the buzzer stopping (ACK) operation is performed while the 3rd stage remote audible
alarm is sounding, the buzzer sound in the bridge and the 2nd and the 3rd stage remote
audible alarms are stopped.
