Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and
systems. To maintain their currency, all Standards are periodically reviewed, and
new editions are published. Between editions, amendments may be issued.
Standards may also be withdrawn. It is important that readers assure themselves
they are using a current Standard, which should include any amendments which
may have been published since the Standard was purchased.

Detailed information about Standards can be found by visiting the Standards Web
Shop at www.standards.com.au and looking up the relevant Standard in the on-line
catalogue.

Alternatively, the printed Catalogue provides information current at 1 January each
year, and the monthly magazine, The Global Standard, has a full listing of revisions
and amendments published each month.

Australian StandardsTM and other products and services developed by Standards
Australia are published and distributed under contract by SAI Global, which
operates the Standards Web Shop.

We also welcome suggestions for improvement in our Standards, and especially
encourage readers to notify us immediately of any apparent inaccuracies or
ambiguities. Contact us via email at [email protected], or write to the Chief
Executive, Standards Australia, GPO Box 476, Sydney, NSW 2001.



This Standard was issued in draft form for comment as DR 02226.

PREFACE

This Standard was prepared by the Standards Australia Committee FP-002; Fire Detection,

Warning, Control and Intercom Systems, to supersede AS 1670.1—1995, Fire detection,

warning, control and intercom systems—System design, installation and commissioning,

Part 1: Fire, and AS 1670.2—1997, Fire detection, warning, control and intercom

systems—System design, installation and commissioning, Part 2: Local fire (which is being

withdrawn). Its preparation is supported by AS 1603, Automatic fire detection and alarm

systems, AS 4428, Control and indicating equipment, AS 7240, Fire detection and fire

alarm systems and EN 54, Fire detection and fire alarm systems component Standards used

in an automatic fire detection and alarm system and installed in accordance with this

Standard.

This Standard incorporates Amendment No. 1 (November 2005). The changes required by the

Amendment are indicated in the text by a marginal bar and amendment number against the

clause, note, table, figure or part thereof affected.

This Standard will be referenced in the Building Code of Australia 2004, thereby

superseding AS 1670.1—1995 and AS 1670.2—1997, which will be withdrawn 12 months

from the date of publication of this Standard.

For the first time this Standard permits the installation of specific components that comply

with ISO equipment Standards (issued as AS Standards) and EN 54. Committee FP-002

intends to review the application of existing Australian equipment Standards where

International Standards exist. This will take effect five years after the publication of the

Australian adoption of the International Standards. Smoke detectors, heat detectors, power

supply units and control and indicating equipment Standards are expected to be among the

first to be reviewed. Other parts of AS 1603 for equipment for which no International

Standard exists will remain current.

This edition covers both monitored and local fire detection and alarm systems and also

allows the use of smoke and heat alarms in some instances. Audible warning within the

building now specifies signals conforming to ISO 7731, Ergonomics—Danger signals for

work places—Auditory danger signals and ISO 8201, Acoustics; Audible emergency

evacuation signal. The building may have a sound system for emergency purposes that

complies with AS 1670.4, Fire detection, warning, control and intercom systems—Sound

systems and intercom systems for emergency purposes. AS 1670.4 has replaced the

emergency warning system installation requirements specified in AS 2220.2, Emergency

warning and intercommunication systems in buildings, Part 2: Equipment design and

manufacture.

The use of the strobes has replaced bells at the main entrance, which is now identified as

the designated building entry point. The new term, designated site entry point, has been

introduced for multi-building sites.

Appendix A ‘Guidance for the selection of detectors’ assists in the design of fire detection

and alarm systems. Appendices B and C provide guidance for the installation of wiring

systems and calculation of power source capacity.

The commissioning section encompasses Appendices E and F, which are report forms to

indicate the installation content and its compliance with this Standard.

Maintenance requirements for fire detection and alarm equipment are given in AS 1851,

Maintenance of fire protection equipment.

The terms ‘normative’ and ‘informative’ have been used in this Standard to define the

application of the Appendix to which they apply. A ‘normative’ Appendix is an integral

part of a Standard, whereas an ‘informative’ Appendix is only for information and

guidance.

This Standard incorporates commentary on some of the clauses. The commentary directly

follows the relevant clause, is designated by ‘ C’ preceding the clause number and is printed
in italics in a box. The commentary is for information only and does not need to be followed

for compliance with the Standard.

Part 1: Fire


S E C T I O N 1 S C O P E A N D G E N E R A L

1.1 SCOPE

This Standard sets out requirements for the design, installation and commissioning of fire

detection and alarm systems comprising components complying with the requirements of

the appropriate product Standards.

1.2 APPLICATION

All fire detection and alarm systems shall comply with the requirements of Section 2 and

Section 3, with the additional requirements of Section 4, Section 5, or Section 6 according

to the actuating device type, and the commissioning requirements of Section 7.

Where a fire detection and alarm system is ancillary to an automatic fire suppression

system, the detection and alarm system shall comply with the appropriate requirements of

this Standard.

This Standard requires that detection be provided throughout all areas of the building,

however, where systems are installed to solely meet the requirements of the BCA, detectors

may only be required in certain nominated areas.
