The Main Alarm Panel can receive external emergency calling from external equip-
ment, by setting Input Port 2 to Backup Navigator on the Service menu. When this
function is active, the Main Alarm Panel shows "External Emergency Call" and the
system goes into the 2nd stage. Neither visual nor audible alarms are released from
the Main Alarm Panel, Timer Reset Panel or Flash Beacon. The audible alarm sounds
at the Backup Officer's Cabin Panel. After the system goes to the 3rd stage, the Main
Alarm Panel, Timer Reset Panel and Flash Beacon do not generate visual or audible
alarms; but, every Cabin Panel sounds the audible alarm.
To stop the buzzer or cancel the emergency call, deactivate the external emer-
gency calling. The system cannot stop the buzzer or cancel the call with the [Re-
set] key on the Main Panel or Timer Reset Panel.
The emergency alarm is also generated when the connection between an external
equipment and input port 2 is disconnected. Check the connection between the Main
Alarm Panel and the external equipment, even if the external equipment does not gen-
erate an alarm.
