9、oreword 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 te

10、chnical 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

11、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

12、 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 f

20、pment ISO 2012 All rights reserved v ISO 7240-10:2012(E) Introduction A fire detection and fire alarm system is required to function satisfactorily, not only in the event of a fire, but also during and after exposure to conditions likely to be met in practice, such as corrosion, vibration, direct im

21、pact, indirect shock and electromagnetic interference. Some tests specified in this part of ISO 7240 are intended to assess the performance of the fire detectors under such conditions. vi ISO 2012 All rights reserved INTERNATIONAL STANDARD ISO 7240-10:2012(E) Fire detection and alarm systems Part 10

22、: Point-type flame detectors 1 Scope This part of ISO 7240 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 buildings. This part of ISO 7240 is not applica

23、ble to flame detectors with special characteristics, developed for specific risks. It can be used as guidance in assessing other types of flame detectors not included in this part of ISO 7240. The performance of flame detectors is assessed from results obtained in specific tests. This part of ISO 72

24、40 is not intended to place any other restrictions on the design and construction of such flame detectors. 2 Normative references The following referenced documents are indispensable for the application of this document.

The detector shall be tested and shall meet the requirements

36、of the tests as specified in Clause 6 . 5.2 Classification Detectors shall conform to one or more of the following classifications to which the manufacturer claims compliance (see Table 1) and according to the requirements of the tests specified in 6.5. Table 1 Flame detector classifications Class C

37、lassification distance m 1 25 2 17 3 12 4 decided by the manufacturer NOTE Detectors may be classified into more than one class, depending on the results of the assessment. 5.3 Individual alarm indication 5.3.1 Each detector shall be provided with an integral red visual indicator, by which the indiv

38、idual detector that released an alarm can be identified, until the alarm condition is reset. Where other conditions of the detector are visually indicated, they shall be clearly distinguishable from the alarm indication, except when the detector is switched into a service mode. For a detachable dete

39、ctor, the indicator may be integral with the base or the detector head. 5.3.2 The visual indicator shall be visible from a distance of 6 m in an ambient light intensity up to 500 lx at an angle of up to: a) 5 from the axis of the detector in any direction, and b) 45 from the axis of the detector in

40、at least one direction. 5.4 Connection of ancillary devices The detector may provide for connections to ancillary devices (remote indicators, control relays, etc.), but open- or short-circuit failures of these connections shall not prevent the correct operation of the detector. 5.5 Monitoring of det

41、achable 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. 5.6 Manufacturer adjustments It shall not be possible to change the manuf

44、 by the use of a code or special tool or by removing the detector from its base or mounting; c) any setting or settings at which the manufacturer does not claim compliance with this part of ISO 7240 shall only be accessible by the use of a code or special tool, and it shall be clearly marked on the

45、detector or in the associated data that if these setting or settings are used, the detector does not comply with this part of ISO 7240.
