Parent topic: 9 SOLAS Regulation XII/12 – Hold, Ballast and Dry Space Water Ingress Alarms

Interpretation

  1 The electrical power supply should be from two separate sources, one should be the main source of electrical power and the other should be the emergency source, unless a continuously charged dedicated accumulator battery is fitted, having arrangement, location and endurance equivalent to that of the emergency source (18 h). The battery supply may be an internal battery in the water level detector system.

  2 The changeover arrangement of supply from one electrical source to another need not be integrated into the water level detector system.

  3 Where batteries are used for the secondary power supply, failure alarms for both power supplies should be provided.
