MARINE ENGINE ROOM COMBINED ALARM SY
Marine engine room combined alarm system is a multifunctional system which could collect al kinds of alarm information in engine room or other places(equipment failure, delay alarm, CO2 discharge, fire alarm, general mobilization, telephone call, engine telegraph, safety warning general alarm or call signals etc., and then transmits collected alarm signals with different alarm tone, light color and alarm priority to multiple engine rooms or places for alarm broadcast. In case of emergencies such as safety alarm of ships, machines and personnel, the alarm system sends out audible and visual alarm signal to immediately inform the relevant staff to take corresponding measures quickly in noisy environment. Engine room combined alarm system is an essential alarm equipment for the safe operation of modern ships, and it s also an important part of modern ship automation system. The alarm system conforms to 1EC60092-203 standard of
National Electrotechnical Commission and meets the standards of lM0 A.1021(26) and other regulations of classification societies at home and abroad.
