Description

The AHD-WAOP K watch keeper panel (Dead Man System) has been designed as emergency call device for the use in engine rooms. In case of an accident the device helps finding the watch keeper as soon as possible. The watch keeper times can be changed after entering a user code. The selected time runs down and has to be acknowledged before it runs off.

If there is no acknowledgement, predefined alarms are raised successively:

• First the display of the device starts flashing,
• followed by the internal buzzer and Alarm Relay “Stage 1”,
• followed by the internal buzzer and Alarm Relay ”Stage 2”,
• followed by Alarm Relay “Stage 3”.

For a better recognition the display of the unit is by turns illuminated red and green.

For the watch keeper panel times up to 30 min can be selected.
If the QUIT button of the AHD-WAOP K is pressed and held longer than 5 seconds, an alarm is triggered.

The watch keeper panel is equipped with a key switch. The key is pulled out when the watch duty begins, and the panel is activated. After the duty has ended, the key is inserted again and the panel is deactivated.

All system configurations as for example change of time, change of passwords and many more are performed with the system keys and are displayed on the screen. Up to four external acknowledgement buttons can be directly connected, allowing an easy acknowledgement of alarms from different points on the bridge or in the engine room (freely extendable by parallel connection). If the used buttons are accordingly equipped, even a simultaneous flashing of internal and external buttons is possible.
