AS 1670.1:2018 Fire detection, warning, control and intercom systems - System design, installation and commissioning, Part 1: Fire
Standards Australia
Amended by: AS 1670.1:2018 Amd 1:2021 Fire detection, warning, control and intercom systems - System design, installation and commissioning, Part 1: Fire
This Standard incorporates Amendment No. 1 (July 2021). The start and end of changes introduced by the Amendment are indicated in the text by tags including the amendment number 1.
The objective of this revision is to remove many of the legacy Standards superseded by a number of AS 7240 Standards which have been published since 2004 as well as incorporating some corrections and clarifications.
It has also introduced AS ISO 7240.17 for short circuit isolators and AS ISO 7240.18 for input/output devices to replace the requirements for distributed CIE used with AS 4428.1 systems.
All references to smoke alarms and heat alarms have been removed.
This edition also permits the use of two editions of relevant Standards relating to components. See Table 1.8 for the list of relevant editions of the Standards which apply throughout this document. Notes to clauses in this Standard do not form a mandatory part for conformance with this Standard. They are
of an advisory nature only and are used to give explanation or guidance to the user on recommended considerations or technical procedures, or to provide an informative cross-reference to other documents or publications.
Statements expressed in mandatory terms in notes are deemed to be requirements of this Standard.
The terms “normative” and “informative” have been used in this Standard to define the application of the appendices to which they apply. A “normative” appendix is an integral part of a Standard, whereas an “informative” appendix is for information and guidance.
Originated as part of AS CA15-1961. Previous edition AS 1670.1-1995. AS 1670.1-1995 and AS 1670.2-1997 revised, amalgamated and designated as AS 1670.1-2004. Second edition AS 1670.1:2015. This edition 2018. Reissued incorporating Amendment No 1 (November 2021).
This Standard sets out requirements for the design, installation and commissioning of fire detection and alarm systems comprising components conforming to the requirements of the appropriate component Standards.
NOTE 1: Where detection and control and indicating equipment forms part of a smoke control system in accordance with AS 1668.1, specific requirements are covered in Clause 7.
