Statutory Text (19 Articles)
1. The system shall be capable of immediate operation at all times and no action of the crew shall be necessary to set it into operation.
2. The system shall be based on the self monitoring principle and include facilities for periodic testing.
3. The system shall not be used for any purpose other than fire detection.
4. The system shall be operated by an abnormal air temperature, by an abnormal concentration of smoke or by other factors indicative of incipient fire in any one of the spaces to be protected. Systems which are sensitive to air temperature shall not operate at less than 57°C and shall operate at a temperature of not greater than 74°C when the temperature increase to those levels is not more than 1°C per minute. The permissible temperature of operation may be increased to 30°C above the maximum deckhead temperature in drying rooms and similar places of normally high ambient temperature. Systems which are sensitive to smoke concentration shall operate on the reduction of the intensity of a transmitted light beam, scatter of a light beam or changes in electric current in an ionising chamber by an amount determined by the Minister. Other methods of operation may be accepted if the Minister is satisfied that such methods are equally effective.
5. The detectors may be arranged to operate the alarm by the opening or closing of contacts or by other appropriate methods and shall be of a resettable type such that after response to an alarm condition they can be restored to normal surveillance without the renewal of any component. They shall be fitted in an overhead position and shall be suitably protected against impact and physical damage. They shall be suitable for use in a marine environment. They shall be placed in an open position clear of beams and other objects likely to obstruct the flow of hot gases or smoke to the sensing element. Detectors operated by the closing of contacts shall be of the sealed contact type.
6. Each section of detectors shall include means for giving a visual and audible alarm automatically at one or more indicating units whenever any detector comes into operation. Such units shall give an indication of any fire and its location in any space served by the system. A list or plan shall be displayed adjacent to each indicating unit showing the spaces covered by each section and the location of that section in the ship.
7. Provision shall be made for testing the correct operation of the detectors and the indicating unit by supplying means for applying hot air or smoke at detector positions.
8. At least one spare detector of each type for each section shall be provided.
9. There shall be not less than two sources of power supply for the electrical equipment used in the operation of the system, one of which shall be an emergency source. The supply shall be provided by separate feeders reserved solely for that purpose. Such feeders shall run to a change-over switch situated in the control station for the system. The electric wiring shall be so arranged as to avoid galleys, machinery spaces and other enclosed spaces having a high fire risk except in so far as it is necessary to provide for fire detection and alarm in such spaces or to reach the appropriate switchboard.
10. Suitable instructions for testing and maintenance shall be available.
