Electronic/Manual Ship Bell

Model KB-12E

The Kahlenberg KB-12E Ship’s Bell package includes a KB-E marine duty outdoor speaker which outputs a mechanical “bell” sound signal upon application of AC or DC current to the unit as specified. The KB-12 Manual Bell is included in this package in order to satisfy USCG and IMO rules that require the bell be operable manually without electric power. This unique combination of items allows for simple electronic operation from an automated signal controller AND manual operation of the bell if required, yet avoids the potential for condensation or ingress of water into an electromechanical bell unit.


  • Allows for automated electronic and manual operation of bells
  • For vessels over 20 metres in length
  • Meets or exceeds IMO and USCG requirements
  • Highly reliable, no maintenance, no electro-mechanical components
