The AlphaAnnounce Digital is a DNV type approved high quality maritime Public Address and General Alarm (PA/GA) system in conformity to SOLAS/IMO and IEC regulations for vessels above 500 gross tonnage and passenger vessels. This modular solution allows officers and crew to communicate through public announcements or via various alarms in case of emergency situations.

The standard system comprises of an eight-channel digital amplifier, a line transfer unit to supply 100V constant output and a back-up panel. The standard power is 2x 320W continuous, with physically separated A and B circuits and dual power supplies and alarm/tone generators to ensure operation in case of any single failure. For passenger vessels and vessels with large crew a dual rack A & B system is available where all components are redundant. The A system is the master controlling both systems, in case of failure the B system will automatically become the master. Up to 64 AlphaAnnounce Digital amplifiers can be combined to create PA/GA systems up to 40kW and up to 512 zones with numerous control panels.
