AS 1670.1:2024 Fire detection, warning, control and intercom systems - System design, installation and commissioning, Part 1: Fire
Standards Australia
This document was prepared by the Standards Australia Committee FP-002, Fire Detection, Warning, Control and Intercom Systems, to supersede AS 1670.1:2018.
The objective of this Standard is to provide uniform minimum requirements for the design, installation and commissioning of fire detection and alarm systems comprising components conforming with the requirements of applicable component Standards.
The major changes in this edition are as follows:
(a) Defined a building to resolve confusion regarding the minimum requirements on a site with multiple structures.
(b) Withdrew definition of “fault tolerant” and use of term throughout the document.
(c) Modified Clause 2.1.1 to clarify the limited application of AS 7240.13 for compatibility.
(d) Clarified that STI need only be met where live speech is provided.
(e) Clarified that STI need only be met where live speech is provided.
(f) Lowered the STI requirement in carparks.
(g) Clarified the STI measurement requirements in SOUs.
(h) Provided greater flexibility in cable marking.
(i) Clarified the termination requirements of optical fibre cables.
(j) Introduced various changes to permit wall mounting of smoke detectors.
(k) Clarified the requirements of smoke detectors in concealed spaces.
(l) Adopted air change in place of air exchange to clarify the application of Table 5.1.5.
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.
