General 29.1.1 Application This chapter details the specifications for fixed fire detection and fire alarm systems as required by this Part 29.2 Engineering Specifications 29.2.1 General Requirements Any required fixed fire detection and fire alarm system with manually operated call points is to be capable of immediate operation at all times The fire detection system is not to be used for any other purpose, except that closing of fire doors and similar functions may be permitted at the control panel The system and equipment are to be suitably designed to withstand supply voltage variation and transients, ambient temperature changes, vibration, humidity, shock, impact and corrosion normally encountered in ships Fire detection systems with a zone address identification capability are to be so arranged that: (1) means are provided to ensure that any fault (e.g power break, short circuit, earth) occurring in the loop will not render the whole loop ineffective; (2) all arrangements are made to enable the initial configuration of the system to be restored in the event of failure (electrical, electronic, informatics, etc.); (3) the first initiated fire alarm will not prevent any other detector from initiating further fire alarms; and (4) no loop will pass through a space twice When this is not practical (e.g for large public spaces), the part of the loop which by necessity passes through the space for a second time is to be installed at the maximum possible distance from the other parts of the loop 29.2.2 Sources of Power Supply There are to be not less than two sources of power supply for the electrical equipment used in the operation of the fire detection and fire alarm system, one of which is to be an emergency source The supply is to be provided by separate feeders reserved solely for that purpose Such feeders are to run to an automatic change-over switch situated in or adjacent to the control panel for the fire detection system 29.2.3 Component Requirements Detectors are to be in accordance with the followings (1) Detectors are to be operated by heat, smoke or other products of combustion, flame, or any combination of these factors Detectors operated by

detectors which covers a control station, a service space or an accommodation space is not to include a machinery space of category A For fire detection systems with remotely and individually identifiable fire detectors, a loop covering sections of fire detectors in accommodation, service spaces and control station is not to include sections of fire detectors in machinery spaces of category A (3) Where the fire detection system does not include means of remotely identifying each detector individually, no section covering more than one deck within accommodation spaces, service spaces and control stations is to normally be permitted except a section which covers an enclosed stairway In order to avoid delay in identifying the source of fire, the number of enclosed spaces included in each section is to be limited as determined by VR In no case more than 50 enclosed spaces are to be permitted in any section If the detection system is fitted with remotely and individually identifiable fire detectors, the sections may cover several decks and serve any number of enclosed spaces Positioning of detectors (1) Detectors are to be located for optimum performance Positions near beams and ventilation ducts or other positions where patterns of air flow could adversely affect performance and positions where impact or physical damage is likely are to be avoided

accordance with the Table 5/29.1 (3) The VR may require or permit different spacing to that specified in Table 5/29.1 if based upon test data which demonstrate the characteristics of the detectors Arrangement of electric wiring (1) Electrical wiring which forms part of the system is to be so arranged as to avoid galleys, machinery spaces of category A, and other enclosed spaces of high fire risk except where it is necessary to provide for fire detection or fire alarm in such spaces or to connect to the appropriate power supply (2) A loop of fire detection systems with a zone address identification capability is not to be damaged at more than one point by a fire 29.2.5 System Control Requirements Visual and audible fire signals (1) The activation of any detector or manually operated call point is to initiate a visual and audible fire signal at the control panel and indicating units If the signals have not received attention with in minutes an audible alarm is to be

Specifications 35.2.1 General Requirements Throughout this chapter the term cargo tank includes also slop tanks The inert gas system referred to in this Part is to be designed, constructed and tested under the provisions of this Chapter It is to be so designed and operated as to render and maintain the atmosphere of the cargo tanks nonflammable at all times, except when such tanks are required to be gas-free The system is to be capable of: (1) inerting empty cargo tanks by reducing the oxygen content of the atmosphere in each tank to a level at which combustion cannot be supported; (2) maintaining the atmosphere in any part of any cargo tank with an oxygen content not exceeding 8% by volume and at a positive pressure at all times in port and at sea except when it is necessary for such a tank to be gas-free; (3) eliminating the need for air to enter a tank during normal operations except when it is necessary for such a tank to be gas-free; and (4) purging empty cargo tanks of a hydrocarbon gas, so that subsequent gas-freeing operations will at no time create a flammable atmosphere within the tank Materials used in inert gas systems are to be suitable for their intended purpose In particular those parts or scrubbers, blowers, non-return devices, scrubber effluent and other drain pipes which may be subject to corrosive action of the gases and or liquids are to be either constructed of corrosion resistant material or lined with rubber, glass fibre epoxy resin or other equivalent coating material 35.2.2 Supply of Inert Gas The inert gas supply may be treated
