The dead man alarm is a safety measure. Whenever there is a alarm during the UMS time the duty engineer is the only person goes down in the engine room to rectify the alarm and his safety is paramount. That is why dead man alarm gets activated automatically together with UMS alarm.
While the duty engineer is working down in the engine room, he needs to reset the UMS alarm every 20 minutes which van be done from every platform in the engine room.
If the duty engineer fails to reset the dead man alarm during these 20 minutes, there will be a warning light indication for the next 3 minutes. The duty engineer can also reset the alarm during these 3 minutes time. But if he fails to reset the dead man alarm during the warning time also then the dead man alarm sounds in the engine room, navigation bridge and also in the accommodation.
And the rest of the crew will come to know that something wrong has happened with the duty engineer and he needs immediate help. This way dead man alarm works for the safety of the duty engineer.
Dead Man Alarm for Engine Room
The dead man alarm system is designed to monitor the ability of the engineer on duty in the engine room. Just before entering the engine room, the engineer on duty should start the adjustable countdown (3-27min) of the dead man alarm system for his own safety.
In case no reset has been trigged by pushing one of the installed reset units during the pre-defined time the dead man alarm system will start an alarm escalation sequence.
If the dead man alarm system does not detect any reset the alarm will escalate to backup engineer cabin to advise disability of duty personnel.
Additionally, the dead man alarm system provides the possibility to call for immediate assistance by pushing one of the reset units for longer than 5 seconds (emergency call).
- intuitive and comfortable use
- compact connecting module picks-up all periphery equipment
- Easy to install
- Modern control philosophy with rotary encoder allows to check all connected devices and links
- Complying with all major classification societies
Requirements regarding Deadman Alarm onboard Ships
The requirements regarding Deadman Alarm onboard ships are crucial for ensuring the safety of personnel, especially in unmanned machinery spaces (UMS) where engineers may work alone. The Deadman Alarm system is designed to monitor the presence of an engineer in the engine room and provide immediate assistance in case of emergencies. Here are the key requirements based on the provided sources:
Activation and Operation:
The Deadman Alarm should automatically activate when there is an alarm during UMS hours, providing safety to duty engineers working alone in the engine room.
The alarm remains active for 20 minutes, allowing the engineer to investigate and reset the alarm if needed. If a fault cannot be rectified within this time, a warning light starts flickering, signaling for assistance.
Resetting:
Duty engineers can manually reset the Deadman Alarm by pressing reset buttons located at various points in the engine room, including at the entrance, in the Engine Control Room, and on alarm consoles on each deck.
Testing:
The Deadman Alarm must be tested every six months onboard ships by the Electro Technical Officer (ETO) to ensure proper functioning. This test involves checking activation and warning time settings, automatic activation after an alarm, and overall system functionality.
Emergency Call:
The Deadman Alarm system allows for an emergency call by pushing one of the reset units for longer than three seconds, signaling a need for immediate assistance in case of an accident or injury5.
By adhering to these requirements and ensuring proper installation, testing, and operation of the Deadman Alarm system onboard ships, maritime safety standards can be upheld, protecting personnel working in critical areas like engine rooms during unmanned hours.
