30、ased on ISO 7240-15:2004. Point-type fire detectors using smoke and heat sensors are general purpose fire detectors for installation in and around buildings. Multi-sensor detectors respond to a broad range of fires and can be designed to achieve high stability against deceptive phenomena that can re

31、sult in unwanted alarms. A fire detection and alarm system is required to function satisfactorily not only in the event of fire, but also during and after exposure to conditions it is likely to meet in practice, including corrosion, vibration, direct impact, indirect shock and electromagnetic interf

32、erence. Specific tests are intended to assess the performance of detectors under such conditions. This edition introduces a requirement that smoke sensors that operate on the principle of scattered or transmitted light to be marked with one of two possible nominal response threshold bands. The avail

33、ability of two of response threshold bands provides installation designers with a detector selection choice to further reduce the risk of unwanted alarms in installations where unfavourable environmental conditions are present. This edition introduces additional requirements for smoke detectors with

34、 more than one smoke sensor. ISO 2014 All rights reserved viiBS ISO 7240-15:2014BS ISO 7240-15:2014Fire detection and alarm systems Part 15: Point-type fire detectors using smoke and heat sensors 1 Scope This part of ISO 7240 specifies requirements, test methods, and performance criteria for point-t

35、ype fire detectors using smoke and heat sensors, incorporating in one mechanical enclosure at least one smoke sensor and at least one other sensor which responds to heat, and in which the signal(s) of the smoke sensor(s) is (are) combined with the signal(s) of the heat sensor(s). The performance of

36、a single sensor within the detector covered by this part of ISO 7240 cannot be sufficient for conformity to other parts of ISO 7240 for the single sensor detector. Certain types of detectors can contain radioactive materials. The national requirements for radiation protection differ from country to

37、country and they are not therefore specified in this standard. However, such detectors are expected to conform to the national requirements and be in line with the recommendations of the Nuclear Energy Agency (NEA) of the Organization for Economic Co-operation and Development (OECD) 1) . For the tes

38、ting of other types of detectors, or detectors working on different principles, this part of ISO 7240 can be used only for guidance. Detectors with special characteristics, developed for specific risks, are not covered in this part of ISO 7240. 2 Normative references The following documents, in whol

46、r shall meet the following requirements. a) Clause 4, which shall be verified by visual inspection or engineering assessment, shall be tested in accordance with Clause 5 and shall meet the requirements of the tests. b) Clauses 7 and 8, which shall be verified by visual inspection. 4.2 Design conside

47、rations Detectors shall be so designed that the signal(s) from the smoke sensor(s), combined with the signal(s) from the heat sensor(s), release an alarm signal. NOTE In some cases, an alarm signal can result from only one element, but the overall fire performance is dependent on signals from more t

48、han one sensor being combined in some form of signal processing. 4.3 Smoke-response value of detectors using scattered or transmitted light Detectors using scattered or transmitted light shall conform to one of the two response threshold value bands specified in Table 1 and the corresponding end-of-

49、test conditions for the test fires specified in 5.22.
