    Product description


    The KB-30A is a IMO type approved electronic ship horn and loud system for marine use that produces a powerful horn signal in excess of 130 decibels (1/3 Octave Band) for vessels up to 75 meters in length.

    It also provides voice amplification and "talkback" function for communication between helm station and personnel on the exterior deck of the vessel. The KB-30A System consists of two major components being the ship horn unit and the control / microphone unit. The KB-30A can also be used in combination with the M-512 Signal Controller, or any Kahlenberg Signal Controller for automated signaling functions.

    The optinal M-512 Sound and Light Control significantly improves safety by producing automatic sound and light signals for navigation as required by USCG, IMO and SOLAS, with a more user friendly and more compact control panel. Producing automated restricted visibility codes (fog), maneuvering codes, and general emergency alarm codes per IMO and SOLAS requirements, the M-512 controls up to two horns, and/or two morse signal lights. It can also be configured for use with external alarm systems and sound surveillance systems to suit the needs of almost any arrangement of modern ship systems.

    • At-Will and Automatic Control of up to two horns and / or two morse lights
    • Connects to any additional external push buttons
    • Generates IMO Navigation Rule 35, Automated Signals for Restricted Visibility (40, 60, 90, and 120 second cycle times)
