.2 in alleyways, stairways and exits giving access to the muster and embarkation stations, as required by regulation III/11.5;
.3 in all service and accommodation alleyways, stairways and exits, personnel lift cars;
.4 in the machinery spaces and main generating stations including their control positions;
.5 in all control stations, machinery control rooms, and at each main and emergency switchboard;
.6 at all stowage positions for firemen's outfits;
.7 at the steering gear; and
.8 at the fire pump, the sprinkler pump and the emergency bilge primp referred to in paragraph 2.4 and at the starting position of their motors.

.1 all internal communication equipment required in an emergency;
.2 the shipborne navigational equipment as required by regulation V/12; where such provision is unreasonable or impracticable the Administration may waive this requirement for ships of less than 5,000 tons gross tonnage;
.3 the fire detection and fire alarm system, and the fire door holding and release system; and
.4 for intermittent operation of the daylight signaling lamp, the ship's whistle, the manually operated call points, and all internal signals that are required in an emergency; unless such services have an independent supply for the period of 36 h from an accumulator battery suitably located for use in an emergency.

.1 one of the fire pumps required by regulation II-2/4.3.1 and 4.3.3;
.2 the automatic sprinkler pump, if any; and
.3 the emergency bilge pump and all the equipment essential for the operation of electrically powered remote controlled bilge valves.

.1 any watertight doors required by regulation 15 to be power-operated together with their indicators and warning signals;
.2 the emergency arrangements to bring the lift cars to deck level for the escape of persons. The passenger lift cars may be brought to deck level sequentially in an emergency.

.1 driven by a suitable prime mover with an independent supply of fuel having a flashpoint (closed cup test) of not less than 43°C;
.2 started automatically upon failure of the electrical supply from the main source of electrical power and shall be automatically connected to the emergency switchboard; those services referred to in paragraph 4 shall then be transferred automatically to the emergency generating set. The automatic starting system and the characteristic of the prime mover shall be such as to permit the emergency generator to carry its full rated load as quickly as is safe and practicable, subject to a maximum of 45 s; unless a second independent means of starting the emergency generating set is provided, the single source of stored energy shall be protected to preclude its complete depletion by the automatic starting system; and
.3 provided with a transitional source of emergency electrical power according to paragraph 4.

.1 carrying the emergency electrical load without recharging while maintaining the voltage of the battery throughout the discharge period within 12% above or below its nominal voltage;
.2 automatically connecting to the emergency switchboard in the event of failure of the main source of electrical power; and
.3 immediately supplying at least those services specified in paragraph 4.

.1 the lighting required by paragraphs 2.1 and 2.1.1;
.2 all services required by paragraphs 2.3.1, 2.3.3 and 2.3.4 unless such services have an independent supply for the period specified from an accumulator battery suitably located for use in an emergency.

.1 in all service and accommodation alleyways, stairways and exits, personnel lift cars and personnel lift trunks;
.2 in the machinery spaces and main generating stations including their control positions;
.3 in all control stations, machinery control rooms, and at each main and emergency switchboard;
.4 at all stowage positions for firemen's outfits;
.5 at the steering gear; and
.6 at the fire pump referred to in paragraph 2.5, at the sprinkler pump, if any, and at the emergency bilge pump, if any, and at the starting positions of their motors.

.1 all internal communication equipment as required in an emergency;
.2 the shipborne navigational equipment as required by regulation V/12; where such provision is unreasonable or impracticable the Administration may waive this requirement for ships of less than 5,000 tons gross tonnage;
.3 the fire detection and fire alarm system; and
.4 intermittent operation of the daylight signaling lamp, the ship's whistle, the manually operated call points and all internal signals that are required in an emergency;
unless such services have an independent supply for the period of 18 h from an accumulator battery suitably located for use in an emergency.

.1 driven by a suitable prime mover with an independent supply of fuel, having a flashpoint (closed cup test) of not less than 43°C;
.2 started automatically upon failure or the main source of electrical power supply unless a transitional source of emergency electrical power in accordance with paragraph 3.1.3 is provided; where the emergency generator is automatically started, it shall be automatically connected to the emergency switchboard; those services referred to in paragraph 4 shall then be connected automatically to the emergency generator; and unless a second independent means of starting the emergency generator; provided the single source of stored energy shall be protected to preclude its complete depletion by the automatic starting system; and
.3 provided with a transitional source of emergency electrical power as specified in paragraph 4 unless an emergency generator is provided capable both of supplying the services mentioned in that paragraph and of being automatically started and supplying the required load as quickly as is safe and practicable subject to a maximum of 45 s.

.1 carrying the emergency electrical load without recharging while maintaining the voltage of the battery throughout the discharge period within 12% above or below its nominal voltage;
.2 automatically connecting to the emergency switchboard in the event of failure of the main source or electrical power; and
.3 immediately supplying at least those services specified in paragraph 4.

.1 the lighting required by paragraphs 2.1, 2.2 and 2.3.1 for this transitional phase, the required emergency electric lighting, in respect of the machinery space and accommodation and service spaces may be provided by permanently fixed, Individual, automatically charged, relay operated accumulator lamps; and
.2 all services required by paragraphs 2.4.1, 2.4.3 and 2.4.4 unless such services have an independent supply for the period specified from an accumulator battery suitably located for use in an emergency.
