001 Preamble

Preamble

This Code has been developed on the basis of the following principles:

  1. The Code is a recommendatory document primarily directed to ships covered by the International Convention for the Safety of Life at Sea, 1974 (1974 SOLAS Convention), as amended, the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78), as amended, and associated codes (IBC, BCH, IGC, Gas Carrier, HSC, 1989 MODU, Nuclear Merchant Ships, Diving and IMDG Codes), 1993 Torremolinos Protocol and Guidelines for Inert Gas Systems (IGS) and Standards for Vapour Emission Control Systems (VEC). Although alarms and indicators required by the dynamically supported craft and similar specialized ships are not specifically included, the Code can be used for guidance where appropriate, and in the future it could be extended to include these instruments. The Code can also be used for guidance for alarms and indicators fitted in excess of or in addition to those required by IMO instruments. It permits present practices in use in world fleets and provides flexibility for alternative methods. It is, however, intended to promote uniformity of the system between ships which will improve crew safety and training.

  2. The Code will benefit designers and operators by consolidating in one document the references to priorities, grouping, locations and types, including colours, symbols, etc., of shipboard alarms and indicators. Where the applicable IMO instruments do not specify the type and location of particular alarms, this information, as far as practicable, is presented in this Code to promote uniform application.

  3. Although preference was given to promoting consistency of terminology with IMO instruments,
    harmonization with the contents of IEC publication 92-203:985 Electrical Installations in Ships. System Design - Acoustic and Optical Signals was achieved as far as practicable.

  4. It is recognized that changing technology and future amendments to the IMO instruments
    referred to in the Code will necessitate changes to the Code itself. Accordingly, the Organization will review the Code as necessary taking into account both amendments to IMO instruments and futu re development.

  5. Administrations are encouraged to give wide dissemination of this Code to shipowners,
    operators, designers and other interested bodies.

01 Purpose and application

Purpose and application

1.1 This Code is a recommendatory document for alarms and indicators. It is intended to provide general design guidance and to promote uniformity of type, location and priority for those alarms and indicators which are required by the 1974 SOLAS Convention, as amended, MARPOL 73/78 as amended, and associated instruments (IBC, BCH, IGC, Gas Carrier, HSC, 1989 MODU, Nuclear Merchant Ships, Diving and IMDG Codes, 1993 Torremolinos Protocol and Guidelines for IGC and Standards for VEC).

1.2 In order to achieve similar uniformity, the Code also serves as guidance for alarms and indicators included in IMO instruments, other than those referred to in 1.1.

1.3 The Code applies to shipboard alarms and indicators on ships constructed on or after 1 July 1996. The Code also applies to major modifications to, or new installations of, alarms and indicators carried out on or after 1 July 1996.

03 General

General

3.1 The presentation of alarms and indicators should be clear, unambiguous, and consistent.

3.2 All required alarms should be indicated by both audible and visual means, except the emergency alarms of 2.2 which should be indicated primarily by audible alarms. In machinery spaces with high ambient noise level, audible alarms should be supplemented by visual alarms in accordance with 5.1. Audible alarms may also be supplemented by visual alarms in accommodation spaces.

3.3 A new alarm condition should be clearly distinguishable from those existing and accepted, e.g. existing and accepted alarms are indicated by a constant light and new alarms are indicated by a flashing light. At control positions or other suitable positions as required, alarm systems should clearly distinguish between normal, alarm, and accepted alarm conditions.

3.4 Alarms should be maintained until they are accepted and the visual indications of individual alarms should remain until the fault has been corrected, when the alarm system should automatically reset to the normal operating condition. If an alarm has been accepted and a second fault occurs before the first is rectified, the audible and visual alarms are to operate again.

3.5 Alarms should only be capable of being cancelled if the condition causing them has been dealt with successfully.

3.6 Required alarm systems should be continuously powered and should have an automatic change-over to a stand-by power supply in case of loss of normal power supply. Emergency alarms and primary alarms should be powered from the main source of electrical power and from emergency source of electrical power defined by SOLAS regulations II-1/42 or II-1/43 unless other arrangements are permitted by those regulations, as applicable, except that:

  1. the power-operated sliding watertight door closure alarm power sources may be those used to close the doors;
  2. the fire-extinguishing medium alarm power source may be the medium itself; and
  3. continuously charged, dedicated accumulator batteries of an arrangement, location, and endurance equivalent to that of the emergency source of electrical power may be used instead of the emergency source.

3.7 Required rudder angle indicators and power-operated sliding watertight door position indicators should be powered from the main source of electrical power and should have an automatic change-over to the emergency source of electrical power in case of loss of normal power supply.

3.8 Failure of the normal power supply of required alarm systems should be indicated by an audible and visual alarm.

3.9 Required alarm systems should, as far as is practicable, be designed on the fail-to-safety principle, e.g., an open detection circuit should cause an audible and visual alarm; see also SOLAS regulations II-2/13.1.2 and II-1/51.1.4.

3.10 Provision should be made for functionally testing required alarms and indicators. The Administration should ensure, e.g., by training and drills, that the crew is familiar with all emergency and primary alarms.

3.11 Required alarms and indicator systems should be functionally independent of control systems and equipment, or should achieve equivalent redundancy. Any additional requirements for particular alarms in the IMO instruments applicable to the ship should be complied with.

3.12 Computer programs for computerized alarm and indicator systems should not be permanently lost or altered as a result of power supply loss or fluctuation. Provision should be made to prevent unintentional or unauthorized alteration of computer programs.

3.13 Cables for emergency alarms and their power sources should be of a fire-resistant type and be run as directly as is considered practicable by the Administration. Equipment and cables for emergency alarms and indicators (e.g. watertight doors' position indicators) should be arranged to minimize risk of total loss of service due to localized fire, collision, flooding or similar damage.

3.14 To the extent considered practicable by the Administration, emergency alarms should be arranged so that the audible alarm signal can be heard regardless of failure of any one circuit or component.

3.15 Means should be provided to prevent normal operating conditions from causing false alarms, e.g., provision of time delays because of normal transients.

3.16 Alarms and indicators on the navigating bridge are to be minimized. Alarms and indicators which are not required alarms and indicators for the navigating bridge should not be placed on the navigating bridge, unless permitted by the Administration.

3.17 The system should be arranged so that all alarm signals can be accepted or cancelled at the appropriate control position only.

3.18 In order to facilitate maintenance and reduce risk of fire or harm to personnel, consideration should be given to providing means of isolation of sensors fitted to tanks and piping systems for flammable fluids or fluids at high temperature or pressure (e.g. valves, cocks, pockets for temperature sensors).

04 Audible alarms and calls

Audible alarms and calls

4.1 Required alarms should be clearly audible and distinguishable in all parts of the spaces where they are called for. Where a distinct difference between the various audible alarms and calls cannot be determined satisfactorily, as in machinery spaces with high ambient noise levels, it is permitted, with the exception of the fire-extinguishing medium alarm, to install common audible alarm and call devices supplemented by visual alarms and indicators identifying the meaning of the audible alarm or call.

4.2 The fire-extinguishing medium alarm should have a characteristic which can be easily distinguished from any other audible alarm or call installed in the space(s) concerned, and should not be combined with any other audible alarm or call.

4.3 Audible alarms and calls should have characteristics in accordance with section 6.

4.4 In large spaces, more than one audible alarm or call device should be installed, in order to avoid shock to persons close to the source of sound and to ensure a uniform sound level over all the space as far as practicable.

4.5 Facilities for adjusting the frequency of audible alarms within the prescribed limits may be provided to optimize their performance in the ambient conditions. The adjustment devices should be sealed, to the satisfaction of the Administration, after setting has been completed.

4.6 Arrangements should not be provided to adjust the sound pressure level of required audible alarms.

4.7 Administrations may accept electronically generated sound signals provided all applicable requirements herein are complied with.

4.8 Administrations may accept the use of a public address system for the general emergency alarm and the fire alarm provided that:

  1. all requirements for those alarms in chapters 11 and III of the 1974 SOLAS Convention, as amended, are met;
  2. all the relevant requirements for required alarms in this Code are met;
  3. the system automatically overrides any other input system when an emergency alarm is required and the system automatically overrides any volume controls provided to give the required output for the emergency mode when an emergency alarm is required;
  4. the system is arranged to prevent feedback or other interference; and
  5. the system is arranged to minimize the effect of a single failure, e.g., by the use of multiple amplifiers with segregated cable routes to public rooms, alleyways, stairways and control stations; use of more than one device for generating electronic sound signals; and use of electrical protection for individual loudspeakers against short circuits.

4.9 The general emergency alarm, fire alarm (if not incorporated in the general emergency alarm system), fire-extinguishing medium alarm, and machinery alarm should be so arranged that the failure of the power supply or the signal generating and amplifying equipment (if any) to one will not affect the performance of the others.

4.10 The general emergency alarm should be audible in the spaces specified by SOLAS regulation Ill/50 with all doors and accesses closed.

4.11 In general, audible alarm sound pressure levels at the sleeping positions in the cabins and one metre from the source should 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. In no case should audible alarm levels in a space exceed 120 dB(A).

4.12 With the exception of bells, audible alarms should have a signal frequency between 200 Hz and 2,500 Hz.

05 Visual alarms, calls and indicators

Visual alarms, calls and indicators

5.1 Supplemental visual alarms and calls provided in machinery spaces with high ambient noise levels and in accommodation spaces should:

  1. be clearly visible and distinguishable either directly or by reflection in all parts of the space in which they are required;
  2. be of a colour and symbol in accordance with tables 6.1.1-6.1.3;
  3. flash in accordance with 5.2;
  4. be of high luminous intensity; and
  5. be provided in multiple in large spaces.

5.2 Flashing alarms and calls should be illuminated for at least 50% of the cycle and have a pulse frequency in the range of 0.5 Hz to 1.5 Hz.

5.3 Visual alarms and indicators on the navigating bridge should not interfere with night vision.

5.4 Alarms and indicators should be clearly labelled unless standard visual indicator symbols, such as those in tables 6.1.1-6.1.3, are used. These standard visual indicator symbols should be arranged in columns for ready identification from all directions. This applies in particular to the emergency alarms in table 6.1.1. Standard visual indicator symbols may also be used on consoles, indicator panels, or as labels for indicator lights.

5.5 Alarm and indicator colours should be in accordance with ISO Standard 2412 as deemed appropriate by the Administration.

5.6 On MODUs, where supplemental visual alarms are installed for general emergency alarms, the colour of these supplemental alarms may be amber, provided they flash with a pulse frequency of at least 4Hz.

06 Characteristics

Characteristics

6.1 The emergency and primary alarms and call signals listed should have the audible and visual characteristics shown in the tables of this section. All other alarms, indicators and call signals should be clearly distinct from those listed in this section to the satisfaction of the Administration. These tables are not all-inclusive and other alarms may be added by the Administration in a manner consistent with this Code.

07 Requirements for particular alarms

Requirements for particular alarms

7.1Personnel alarm
7.1.1 The personnel alarm should automatically give an alarm on the navigating bridge or in the officers' quarters as appropriate, if it is not reset from the machinery spaces in a period satisfactory to the Administration, but not exceeding 30 minutes.


7.1.2 A pre-warning signal should be provided in the machinery spaces which operates 3 minutes before the alarm required by 7.1.1 is given.


7.1.3 The alarm system is to be put into operation:

  1. automatically when the engineer on duty has to attend machinery spaces in case of a machinery alarm; or
  2. manually by the engineer on duty when attending machinery spaces on routine checks.

7.1.4 The alarm system is to be disconnected by the engineer on duty after leaving the machinery spaces. When the system is brought into operation in accordance with 7.1.3.1, disconnection should not be possible before the engineer has accepted the alarm in the machinery spaces.


7.1.5 The personnel alarm may also operate the engineers' alarm.

7.2 Engineers' alarm
In addition to manual operation from the machinery space, the engineers' alarm on vessels with periodically unattended machinery spaces should operate when the machinery alarm is not accepted in the machinery spaces or control room in a specified period of time, e.g. two minutes.

 

 

08 Grouping of alarms and indicators

Grouping of alarms and indicators

8.1 Where audible and visual alarms and indicators are required at central positions, e.g. on the navigating bridge, in the machinery space, or engine control room, the alarms and indicators should be arranged in groups, as far as practicable, except emergency alarms.

8.2 The scope of alarms and indicators will vary with the type of ship and machinery. The basic recommendations given in tables 8.1 through 8.3 should be adhered to.

8.3 When visual alarms are grouped in accordance with 2.10.2, individual alarms should be provided at the appropriate position to identify the specific alarm condition.

8.4 The purpose of grouping is to achieve the following:

  1. In general: to reduce the variety in type and number of audible and visual alarms and indicators so as to provide quick and unambiguous information to the personnel responsible for the safe operation of the ship.
  2. On the navigating bridge:
    2.1 to enable the officer on watch to devote full attention to the safe navigation of the ship;
    2.2 to readily identify any abnormal situation requiring action to maintain the safe navigation of the ship; and
    2.3 to avoid distraction by alarms which require attention but have no direct influence on the safe navigation of the ship and which do not require immediate action to restore or maintain the safe navigation of the ship.
  3. In the machinery space/engine control room, to readily identify and locate any area of abnormal conditions (e.g. main propulsion machinery, steering gear, bilge level) and to enable the degree of urgency for remedial action to be assessed.
  4. In the engineers' public rooms and to each of the engineers' cabins on ships where the machinery space/engine control room is periodically unattended, to inform the engineer officer on watch of any alarm situation which requires immediate presence in the machinery space/engine control room.
