The AHD-WAOP system complies with the requirements of IEC 62616-1 and is designed to establish a Bridge Navigation Watch Alarm System (BNWAS). With the central components AHD-WAOP and AHD-WAOP K for monitoring watch duty and watch rounds, Böning offers compact and effective devices for use as a watch alarm panel or a watch round alarm panel. The preset watch alarm time must be acknowledged before it expires. If timely acknowledgment is not received, an alarm is triggered in several stages as follows:
1. Notification
2. Pre-alarm
3. Alarm in the bridge section
4. General Alarm (alarm on the entire ship)
Depending on the configuration and system requirements, the following components can be combined in the Bridge Navigation Watch Alarm System:
- AHD-WAOP: Watch Alarm Operation Panel (BNWAS), central control unit for the bridge
- AHD-WAOP K: Watchman Alarm Panel (Dead Man System) with key switch
- AHD-WAOP MD / MDA: Set with motion detector and adapter module
- AHD-WAOP SA: Alarm panel (flush-mounted)
- AHD-WAOP SA AP: Alarm panel (surface-mounted)
- AHD-WAOP SK: Reset panel with emergency call (flush-mounted)
- AHD-WAOP SK AP: Reset panel with emergency call (surface-mounted)
- AHD-WAOP SB: Alarm panel with emergency call (bridge version with mushroom pushbutton)
