Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO XXXXX was prepared by Technical Committee ISO/TC 8, Ships and Marine Technology, Subcommittee SC 1, Lifesaving and Fire Protection. It includes three normative and one informative Annexes.
COMMITTEE DRAFT ISO/CD XXXXX
Ships and marine technology - Point-type resettable flame detectors for ships
This International Standard specifies requirements, test methods and performance criteria for point-type, resettable flame detectors that operate using radiation from a flame for use in fire detection systems installed in ship.

For the purposes of this document, the following terms and definitions apply:
3.1
infrared (IR) detector
a flame detector responding only to radiation having wavelengths greater than 850 nm
3.2
ultra-violet (UV) detector
a flame detector responding only to radiation having wavelengths less than 300 nm
3.3
multi band detector
a flame detector having two or more sensing elements, each responding to radiation in a distinct wavelength range and each of whose outputs may contribute to the alarm decision
NOTE The alarm decision may be based on any arithmetic or logical combination of the individual signals.
3.4
sensitivity
a measure of the ability of a flame detector to detect fires.
NOTE Sensitivity is not necessarily directly related to the response point.
3.5
detector classification
a classification of flame detectors to indicate their relative sensitivity to fire
NOTE Class 1 indicates the highest sensitivity and Class 3 the lowest sensitivity acceptable within this standard.
3.6
response point
distance D, measured in accordance with 5.1 .3, at which the individual flame detector under test gives an alarm signal.
3.7
sensitivity adjustment
any adjustment of the detector or of the alarm criteria within the supply and monitoring equipment that leads to a change in sensitivity.
4.1 Compliance
The detector shall be verified by visual inspection or engineering assessment as complying with the requirements of this clause. When tested in accordance with the procedures in 5, the detector shall comply with the specified requirements.
4.2 Classification
Detectors shall conform to one or more of the following classifications: Class I , Class 2 or Class 3 according to the results of the tests specified in 5.2.4.
4.3 Individual alarm indication
Each detector shall be provided with an integral red visual indicator, by which the individual detector, which released an alarm, may be identified, until the alarm condition is reset. Where other conditions of the detector may be visually indicated, they shall be clearly distinguishable from the alarm indication, except when the detector is switched into a service mode. For detachable detectors the indicator may be integral with the base or the detector head.
4.4 Connection of ancillary devices
Where the detector provides for connections to ancillary devices (e.g., remote indicators, control relays etc.), open- or short-circuit failures of these connections shall not prevent the correct operation of the detector.
4.5 Monitoring of detachable detectors
For detachable detectors, a means shall be provided for a remote monitoring system (e.g., the control and indicating equipment) to detect the removal of the head from the base, in order to give a fault signal.
4.6 Manufacturer's adjustments
It shall not be possible to change the manufacturer's settings except by special means (e.g., the use of a special code or tool) or by breaking or removing a seal.
4.7 On-site sensitivity adjustment
4.7.1 If there is provision for on-site sensitivity adjustment of the detector then:
a) for each setting, at which the manufacturer claims compliance with this standard, the detector shall comply with the requirements of this standard and shall achieve a classification corresponding to that marked on the detector for that setting;
b) for each setting in a), access to the adjustment means shall only be possible by the use of a code or special tool or by removing the detector from its base or mounting;
c) any setting(s), at which the manufacturer does not claim compliance with this standard, shall only be accessible by the use of a code or special tool, and it shall be clearly marked on the detector or in the associated data, that if these setting(s) are used, the detector does not comply with the standard.
4.7.2 These adjustments may be carried out at the detector or at the control and indicating equipment.
4.8 Data
4.8.1 Detectors shall either be supplied with sufficient technical, installation and maintenance data to enable their correct installation and operation or, if all of these data are not supplied with each detector, reference to the appropriate data sheet shall be given on, or with each detector.
NOTE Additional information may be required by organizations certifying that detectors produced by a manufacturer conform to the requirements of this standard.
4.8.2 To enable correct operation of the detectors, these data should describe the requirements for the correct processing of the signals from the detector. This may be in the form of a full technical specification of these signals, a reference to the appropriate signaling protocol, or a reference to suitable types of control and indicating equipment, etc.
