General Alarm System And Public Address System For Marine

MPA-9000 Series PA/GA System

Public address and gneral alarm system for on and offshore applications.

General Discription

Public address system is a marine and offshore PA/GA system. The Public Address System (PA) and General Alarm System (GA) are very important in ensuring the safety of facilities and people on board. The system must be able to address emergency situations accurately and seamlessly, integrated with various other alarm system.

In particular, this system is designed to respond precisely to emergency situations through the connection with various alarm system. In explosion endangered areas, an explosion-proof speaker or an intrinsically safe microphone is supposed to operate.

The PAGA system abides by the following regulations :

1. International Electro-Technical Comission (IEC).
2. International Maritime Organization (IMO) SOLAS.
3. Nautical Safety (Rules for the Classification of Ships,DNV).

This system was tested at the IEC60945 standard and approved for CE by DNV. The type approval was done from Lloyd Register, CCS, and DNV.
