Bridge Navigational Watch Alarm System
The BNWAS device monitors the selected watch period. If no reset is received within this period, it activates the alarm outputs in stages.
Product Features
Adjustable period: 3–12 minutes
The watch monitoring period is set through the device menu.
4 independent reset inputs
The other reset buttons continue to operate even if one reset button remains pressed.
Staged alarm outputs
If no reset is received, the four alarm stages activate in sequence.
Password-protected settings
A user password is required to access the settings menu.
Basic Operation
- Power on the device and check its operating status on the main screen.
- Press F to access the settings menu and enter the user password.
- Set the watch period between 3 and 12 minutes and enable the system.
- During normal operation, press any physical reset button or the 0 key on the device to restart the monitoring period.
A physical reset is triggered by a new button press. Holding the button does not generate continuous resets, and releasing it does not trigger a reset.
