1.1  Scope This Standard specifies performance of duct sampling equipment (DSE) comprising an AS 7240 series smoke detector and duct sampling housing. 1.2  Application This Standard applies to DSEs intended for installation in accordance with AS 1670.1. Where the duct sampling housing is part of duct sampling equipment conforming to one of the standards in the referenced documents, the only test required is the sensitivity test specified in Clause 2.2. For duct sampling housings without a certificate of conformity to one of the referenced standards, then all requirements of this Standard must be assessed and tested.1.4  Terms and definitions For the purpose of this Standard, the definitions given in AS 7240.1 and those below apply. 1.4.1 duct sampling equipment (DSE) a duct sampling housing conforming to either AS 1603.13—1998 or EN 54‑27 or UL 268A which incorporates a smoke detector conforming to the AS 7240 series 1.4.2 extra low voltage (ELV) as defined in AS/CA S009 1.5  Tolerances Unless otherwise stated, the tolerances for the environmental test parameters shall be as given in the basic reference standards for the test (e.g. the relevant part of IEC 60068 series). If a specific tolerance or deviation limit is not specified in a requirement or test procedure, then a deviation limit of ± 5 % shall be applied.
2.1  General Duct sampling equipment shall incorporate a smoke detector conforming to the AS ISO 7240 series and a duct sampling housing conforming to at least one of the following: (a) AS 1603.13—1998. (b) EN 54‑27. (c) UL 268A. A duct sampling housing conforming to (a), (b) or (c) above is considered to meet the requirements of Clauses 3.1, 3.3, 3.4, 3.5, 3.6, 5.3. The associated detector shall reliably respond to defined changes in smoke density sampled by the DSE from moving air within the duct. 2.2  Sensitivity When tested in accordance with Appendix A, the nominal sensitivity value shall be equal to or less than 10 % Obs/m and all individual results shall be within ± 50 % of the nominal value. 2.3  Air leakage When the DSE housing has not been tested to one of the referenced DSE Standards it shall be tested in accordance with Appendix B and meet the requirements of Table 2.1.
3.1  General The material, form and arrangement of components shall be such that it will be practicable to install and maintain the DSE in a reliable condition. DSEs intended for use in situations where they are likely to become wet shall have an appropriate IP rating. Where the DSE can be separated from its mounting or terminating facilities, those facilities shall be considered part of the DSE for the purpose of this Standard.General design features of DSEs shall be as follows: (a) Suitability — Design and construction of a DSE shall conform with the performance requirements of Section 5. (b) Electrical and electronic components — Electrical and electronic components shall be of a quality suitable to withstand the maximum and minimum temperatures that will occur inside the detector when subjected to tests specified in Section 5. Equipment design shall ensure operating conditions of the components used shall not exceed the limits specified by the components’ manufacturer. (c) Mechanical design — Mechanical strength of all DSE parts, including the detector enclosure and subassemblies, shall be capable of supporting the weight of components mounted thereon. The enclosure shall also be sufficiently rigid to prevent any detrimental effects due to handling in service. 3.2  Electrical requirements 3.2.1  Electrical safety Where the maximum working voltage exceeds extra‑low voltage (ELV), the DSE shall conform with the appropriate requirements of AS/NZS 3100. 3.3  Connecting facilities The means of connection shall not permit disconnection of the DSE or its associated detector without initiating a fault or alarm signal at the control and indicating equipment (CIE). Where this requirement can be achieved without providing separate terminations for each incoming and outgoing conductor, such alternative means of connection shall be considered satisfactory. This requirement includes any arrangement by which the DSE can be detached from its terminating facility. The terminations shall be designed so conductors connected thereto can be rigidly and effectively clamped between metal surfaces, or soldered, to ensure the connection made will not slacken or overheat under normal conditions of use.
