Marine Announcement Systems: Clear Communication When It Matters Most

Effective communication on board is essential not just for smooth operations but also for safety and emergency preparedness. Marine Announcement Systems, also known as Public Address (PA) or General Alarm (GA) systems, are vital tools for broadcasting important messages, instructions, and alerts throughout a vessel. At Serden Ship Supply Marine Electric & Electronics Ltd., we design, supply, install, and maintain IMO and SOLAS-compliant marine announcement systems tailored to the unique needs of each vessel type.

Whether for routine operations, passenger instructions, emergency alarms, or crew coordination—clarity, reach, and reliability are the foundations of our systems.

 What is a Marine Announcement System?

A Marine Announcement System is a centralized audio distribution system that allows the bridge or control room to broadcast voice announcements and automated alarms to all or selected zones of the ship.

These systems are critical for:

• Safety alarms (fire, abandon ship, man overboard)

• Routine announcements (arrival info, weather updates)

• Crew coordination

• Emergency evacuation procedures

• Passenger entertainment or information (on cruise ships)

They are often integrated with General Alarm (GA) systems and Emergency Notification Systems (ENS) for enhanced safety management.
