Engineering specifications
2.1
General requirements
2.1.1
Any required fixed fire detection and fire alarm system with manually
operated call points shall be capable of immediate operation at all times (this does
not require a backup control panel). Notwithstanding this, particular spaces may be
disconnected, for example, workshops during hot work and ro-ro spaces during on
and off-loading. The means for disconnecting the detectors shall be designed to
automatically restore the system to normal surveillance after a predetermined time
that is appropriate for the operation in question. The space shall be manned or
provided with a fire patrol when detectors required by regulation are disconnected.
Detectors in all other spaces shall remain operational.
2.1.2
The fire detection system shall be designed to:
.1 control and monitor input signals from all connected fire and
smoke detectors and manual call points;
.2 provide output signals to the navigation bridge, continuously
manned central control station or onboard safety centre to notify
the crew of fire and fault conditions;
.3 monitor power supplies and circuits necessary for the operation of
the system for loss of power and fault conditions; and
I:\MSC\88\26-Add-1.doc
MSC 88/26/Add.1 Annex 5, page 3 .4 the system may be arranged with output signals to other fire safety
systems including:
.1
paging systems, fire alarm or public address systems;
.2
fan stops;
.3
fire doors;
.4
fire dampers;
.5
sprinkler systems;
.6
smoke extraction systems;
.7
low-location lighting systems;
.8
fixed local application fire-extinguishing systems;
.9
closed circuit television (CCTV) systems; and
.10
other fire safety systems.
2.1.3
The fire detection system may be connected to a decision management
system provided that:
.1 the decision management system is proven to be compatible with
the fire detection system;
.2 the decision management system can be disconnected without
losing any of the functions required by this chapter for the fire
detection system; and
.3 any malfunction of the interfaced and connected equipment should
not propagate under any circumstance to the fire detection system.
2.1.4
Detectors and manual call points shall be connected to dedicated sections
of the fire detection system. Other fire safety functions, such as alarm signals from
the sprinkler valves, may be permitted if in separate sections.
2.1.5
The system and equipment shall be suitably designed to withstand supply
voltage variation and transients, ambient temperature changes, vibration, humidity,
shock, impact and corrosion normally encountered in ships. All electrical and
electronic equipment on the bridge or in the vicinity of the bridge shall be tested for
electromagnetic compatibility, taking into account the recommendations developed
by the Organization*.
2.1.6
Fixed fire detection and fire alarm systems with individually identifiable fire
detectors shall be so arranged that:

Annex 5, page 4
.1 means are provided to ensure that any fault (e.g., power break,
short circuit, earth, etc.) occurring in the section will not prevent the
continued individual identification of the remainder of the
connected detectors in the section;
.2 all arrangements are made to enable the initial configuration of the
system to be restored in the event of failure (e.g., electrical,
electronic, informatics, etc.);
.3 the first initiated fire alarm will not prevent any other detector from
initiating further fire alarms; and
.4 no section will pass through a space twice. When this is not
practical (e.g., for large public spaces), the part of the section
which by necessity passes through the space for a second time
shall be installed at the maximum possible distance from the other
parts of the section.
2.1.7
In passenger ships, the fixed fire detection and fire alarm system shall be
capable of remotely and individually identifying each detector and manually
operated call point. Fire detectors fitted in passenger ship cabins, when activated,
shall also be capable of emitting, or cause to be emitted, an audible alarm within the
space where they are located. In cargo ships and on passenger ship cabin
balconies the fixed fire detection and fire alarm system shall, as a minimum, have
section identification capability.
2.2
Sources of power supply
2.2.1
There shall be not less than two sources of power supply for the electrical
equipment used in the operation of the fixed fire detection and fire alarm system,
one of which shall be an emergency source of power. The supply shall be provided
by separate feeders reserved solely for that purpose. Such feeders shall run to an
automatic change-over switch situated in or adjacent to the control panel for the fire
detection system. The main (respective emergency) feeder shall run from the main
(respective emergency) switchboard to the change-over switch without passing
through any other distributing switchboard.
2.2.2
There shall be sufficient power to permit the continued operation of the
system with all detectors activated, but not more than 100 if the total exceeds this
figure.
2.2.3

Installation requirements
2.4.1
Sections
2.4.1.1 Detectors and manually operated call points shall be grouped into sections.
2.4.1.2 A section of fire detectors which covers a control station, a service space or
an accommodation space shall not include a machinery space of category A or a
ro-ro space. A section of fire detectors which covers a ro-ro space shall not include
a machinery space of category A. For fixed fire detection systems with remotely and
individually identifiable fire detectors, a section covering fire detectors in
accommodation, service spaces and control stations shall not include fire detectors
in machinery spaces of category A or ro-ro spaces.
2.4.1.3 Where the fixed fire detection and fire alarm 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
shall 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 shall be limited as determined by the
Administration. 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.
2.4.1.4 In passenger ships, a section of detectors and manually operated call
points shall not be situated in more than one main vertical zone, except on cabin
balconies.
2.4.2
Positioning of detectors
2.4.2.1 Detectors shall 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, shall
be avoided. Detectors shall be located on the overhead at a minimum distance
of 0.5 m away from bulkheads, except in corridors, lockers and stairways.
2.4.2.2 The maximum spacing of detectors shall be in accordance with the table

demonstrate the characteristics of the detectors. Detectors located below moveable
ro-ro decks shall be in accordance with the above.
2.4.2.3 Detectors in stairways shall be located at least at the top level of the stair
and at every second level beneath.
2.4.2.4 When fire detectors are installed in freezers, drying rooms, saunas, parts of
galleys used to heat food, laundries and other spaces where steam and fumes are
produced, heat detectors may be used.
2.4.2.5 Where a fixed fire detection and fire alarm system is required by
regulation II-2/7.5 of the Convention, spaces having little or no fire risk need not be
fitted with detectors. Such spaces include void spaces with no storage of
combustibles, private bathrooms, public toilets, fire-extinguishing medium storage
rooms, cleaning gear lockers (in which flammable liquids are not stowed), open deck
spaces and enclosed promenades having little or no fire risk and that are naturally
ventilated by permanent openings.
2.4.3
Arrangement of cables
2.4.3.1 Cables which form part of the system shall 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 alarms in such
spaces or to connect to the appropriate power supply.

cannot be damaged at more than one point by a fire.
2.5
System control requirements
2.5.1
Visual and audible fire signals*
2.5.1.1 The activation of any detector or manually operated call point shall initiate a
visual and audible fire detection alarm signal at the control panel and indicating
units. If the signals have not been acknowledged within 2 min, an audible fire alarm
shall be automatically sounded throughout the crew accommodation and service
spaces, control stations and machinery spaces of category A. This alarm sounder
system need not be an integral part of the detection system.
2.5.1.2 In passenger ships, the control panel shall be located in the onboard safety
centre. In cargo ships, the control panel shall be located on the navigation bridge or
in the fire control station.
2.5.1.3 In passenger ships, an indicating unit that is capable of individually
identifying each detector that has been activated or manually operated call point that
has operated shall be located on the navigation bridge. In cargo ships, an indicating
unit shall be located on the navigation bridge if the control panel is located in the fire
control station. In cargo ships and on passenger cabin balconies, indicating units
shall, as a minimum, denote the section in which a detector has activated or manually
operated call point has operated.

2.5.1.4 Clear information shall be displayed on or adjacent to each indicating unit
about the spaces covered and the location of the sections.
2.5.1.5 Power supplies and electric circuits necessary for the operation of the
system shall be monitored for loss of power and fault conditions as appropriate
including:
.1 a single open or power break fault caused by a broken wire;
.2 a single ground fault caused by the contact of a wiring conductor
to a metal component; and
.3 a single wire to wire fault caused by the contact of two or more
wiring conductors.
Occurrence of a fault condition shall initiate a visual and audible fault signal at the
control panel which shall be distinct from a fire signal.
2.5.1.6 Means to manually acknowledge all alarm and fault signals shall be
provided at the control panel. The audible alarm sounders on the control panel and
indicating units may be manually silenced. The control panel shall clearly
distinguish between normal, alarm, acknowledged alarm, fault and silenced
conditions.
2.5.1.7 The system shall be arranged to automatically reset to the normal operating
condition after alarm and fault conditions are cleared.
2.5.1.8 When the system is required to sound a local audible alarm within the
cabins where the detectors are located, a means to silence the local audible alarms
from the control panel shall not be permitted.
2.5.1.9 In general, audible alarm sound pressure levels at the sleeping positions in
the cabins and 1 m from the source shall be at least 75 dB(A) and at least 10 dB(A)
above ambient noise levels existing during normal equipment operation with the ship
under way in moderate weather. The sound pressure level should be in
the 1/3 octave band about the fundamental frequency. Audible alarm signals shall
not exceed 120 dB(A).
2.5.2
Testing
Suitable instructions and component spares for testing and maintenance shall be
provided. Detectors shall be periodically tested using equipment suitable for the
types of fires to which the detector is designed to respond.
