4 Detail Requirements – Fire Detection and Fire Confirmation (system B)

  4.1 For systems of type B (see table 3-1) an efficient fire detection and fire confirmation system covering all parts of the ro-ro or special category spaces should be provided.

  4.2 The fire detection system should consist of flame detectors and smoke detectors of approved types. The flame detectors should be installed under fixed continuous decks according to the limitation and application defined by the maker and the approval certificate. The smoke detector arrangement shall comply with the International Code for Fire Safety Systems (FSS Code). Smoke detectors with a spacing not exceeding 11 m should be installed under hoistable ramps.

  4.3 A colour TV monitoring system should cover all parts of the ro-ro or special category spaces. Cameras need not be installed below hoistable decks if the camera arrangement can identify smoke (confirm fire) based on positions under a fixed continuous deck.

  4.4 The relevant section of the deluge system should be automatically released when two detectors covering this area activate. Systems being released when only one detector activates may also be accepted. The automatic release should not prevent manual operation (both opening and closing) of the section valves. The automatic release may be disconnected during on- and off-loading operations, provided that this function is automatically re-connected after a pre-set time being appropriate for the operations in questions.

  4.5 All release controls for the deluge system, monitor(s) for the CCTV system and the control panel (or an indication panel) for the fire detection system should be available and grouped together in a continuously manned control station.
