KB-30 Electronic Horn System
INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
1)
GENERAL
- The Kahlenberg KB-30 is an Electronic Horn/Hailing system for marine
use that produces in excess of 130 dB (1/3 Octave Band) @ 1 Meter, as required by IMO
Regulations for vessels up to 75 meters in length. The KB-30 also serves as a voice
amplification unit. The KB-30 System consists of two major components being the KB-30
Horn/Driver Unit, and the M-511D control/microphone unit. The function of the KB-30 Horn is
that of a high powered speaker. The function of the M-511D Whistle Control is to provide
convenient operation of a sound signaling device from a single control panel for At-Will,
Restricted Visibility, and Maneuvering signaling as required. The M-511D also generates the
SOLAS General Alarm Signal, or may be integrated with another alarm system on board which
generates this signal.
The M-511D is to be used with the KB-30 Electronic Horn Assembly,
and can also be used with an additional secondary signaling device such as a Kahlenberg
Air Horn
. A horn selector switch is included on the M-511D to select between the KB-30 and
secondary horn.
