FOREWORD

The criteria adopted for revising this Standard include reliability, integrity, functionality

and performance of fire protection systems and equipment. Consideration has also been

given to the interfaces between equipment for fire detection and firefighting.

The Standard contains requirements formulated as a means of satisfying Occupational

Health and Safety (OH&S) regulations and the maintenance provisions of the Building

Code of Australia (BCA). It may also form the basis for performance-based solutions. The

combination of inspection, test, preventive maintenance and survey may demonstrate

compliance with the maintenance requirements of the Building Code of Australia.

Training of personnel to the appropriate levels for the carrying out of inspection, test,

preventive maintenance and survey of fire protection systems has not been directly

addressed in this Standard; however, it is recognized that effective maintenance programs

depend on suitably trained personnel.

An explanation of how this Standard is intended to be implemented is given in Section 1

detailing a four-stage approach of inspection, test, preventive maintenance and survey,

coupled with records to be kept and reports to be made and culminating in the issue of a

final condition report.

Scope and frequency provisions have been revised and, wherever practicable, specific test

results are required to be recorded. The former tick-the-box approach has been abandoned

in favour of specific yes/no and quantitative answers throughout.

The revised inspection, test, preventive maintenance and survey regimes in this Standard

address the functional aspects of installed fire protection systems and equipment on a

periodic basis, with the objective that systems and equipment operate effectively at all

times. The regimes aim to ensure that fire protection systems and equipment are in working

order throughout the year or period of interest; not only at the time of annual inspection and

test. A significant objective of this Standard is to provide reliability of fire protection

systems and equipment, linking design, installation, commissioning and maintenance.

Continuous correct functioning is a basic criterion, and a new annual survey requirement

also assures that system performance capability (efficacy) is not degraded by building or

occupancy changes, which could otherwise adversely affect the capability of the system to

perform as originally intended.

AS 1851 includes a requirement to annually test all aspects of system interconnection; for

example, detection and alarm systems with atrium smoke exhaust plant, alarm systems with

stairwell pressurization, automatic fire sprinkler systems with HVAC fire mode operation

and warning facilities. This will require adequate documentation of interconnections

between the various systems as required in the design, installation and commissioning

standards.

This Standard complements AS 4655, Fire safety audits. AS 4655 provides a methodology

for examining, where appropriate, by a process of audit, fire safety measures in order to

satisfy appropriate, benchmarks, such as Standards, legislation, contractual arrangements,

regulation and insurance requirements. This Standard provides a set of requirements to

increase the probability that fire protection systems and equipment will function as intended

by the respective design, installation and commissioning Standards, thus achieving

reliability.

Maintenance is concerned with the principle that a system will continue to perform to a

design Standard on a pre-determined and regular basis. The audit function is a broader

process undertaken by people skilled in conducting audits. An audit can be undertaken to

provide different levels of confidence that compliance with benchmarks have, or have not,

been met from a basic desktop audit of records or systems design, through to full

verification of fire safety. An audit can confirm the currency or indicate omissions in the

maintenance process. If the audit process reveals a requirement for further examination, any

subsequent inspection, test and survey should follow this Standard.

1.1 SCOPE

This Standard sets out requirements for the inspection, test, preventive maintenance and survey

(ITM&S) of fire protection systems and equipment.

NOTE: This Standard may be used as the basis for performance-based solutions.

1.2 OBJECTIVE

The objective of this Standard is to maximize the reliability of fire protection systems and equipment

such that the systems and equipment meet the requirements of the relevant design, installation and

commissioning Standards and are likely to continue to do so until the next scheduled activity.

1.3 APPLICATION

This Standard is intended to provide a systematic and uniform basis for building owners and

managers, regulators, contractors, insurers and others to implement and administer inspection, test,

preventive maintenance and survey programs applicable to fire protection systems and equipment.

1.4 REFERENCED DOCUMENTS

The documents referenced in this Standard are listed in Appendix A.

1.5 DEFINITIONS

For the purpose of this Standard the definitions below apply.

1.5.1 Aggressive environment

Harsh operating conditions that impose additional stress on fire protection systems and equipment.

1.5.2 Competent person

A Person who has acquired through training, qualification, experience, or a combination of these, the

knowledge and skill enabling him/her to correctly perform the required task, and who is registered or

licensed by a recognized body acknowledging the training, qualification, experience or skills.

1.5.3 Critical defect

Defect likely to render a system inoperative.

1.5.4 Heating, ventilation and airconditioning (HVAC)

Air-handling plant in buildings, used in either, or both, general and fire mode.

1.5.6 Maintenance

Inspection, test, preventive maintenance and survey at specific intervals and rectification of defects,

which is necessary to ensure the continuing reliability of fire protection systems and equipment.

1.5.7 Preventive maintenance

Actions including lubrication, cleaning, adjustment and replacement of components at a

predetermined frequency, to minimize the incidence of breakdown.

1.5.8 Rectification

The repair or replacement of components found to be defective through the maintenance process.

1.5.12 Survey

Visual inspection to identify if fire protection systems or equipment have been altered, damaged or

compromised.

NOTE: This survey together with the inspection, test and preventive maintenance regime demonstrates that

the fire protection systems or equipment are functional and capable of performing to a standard not less than

that to which they were originally designed. A further goal is to determine that the system is not

compromised by occupancy or building alterations. Where a system upgrade has resulted in a change of the

performance capability, the system should be appraised against the upgraded level of performance.

1.7 MAINTENANCE PROCESS

1.7.1 General

A maintenance process shall consist of four stages (see Figure 1.7). Each activity referred to in

Stage 1 in Figure 1.7 shall be undertaken. When an activity has been completed, the result shall be

recorded, followed by whether the action resulted in a pass or a fail. A comments column is provided

to record specific information, which may subsequently be contained in the report to the building

owner or the building owners agent.

1.7.2 Stage 1

Stage 1 is a set of requirements included in the systems and equipment sections (Sections 2 to 19)

which appear in schedules, referenced by clauses in this Standard. The preventive maintenance

activities do not have pass/fail criteria because these activities are not required to satisfy an action.

1.7.3 Stage 2

Stage 2 covers the records that are required to be kept for each functional activity and the information

to be recorded (see Stage 2 in Figure 1.7). Records schedules are incorporated in the maintenance

schedules.

1.7.4 Stage 3

Stage 3 covers reporting and rectification. Where failures have been identified, they shall be reported

to the owner or agent for rectification (see Stage 3 in Figure 1.7). Where the system or equipment is

operational, an activity report shall be issued. This report may contain outstanding rectification work

to be addressed, which will appear at the commencement of the next scheduled maintenance routine

unless rectification has occurred.

1.7.5 Stage 4

Stage 4 is the result of all activities having been completed; the annual condition report can then be

issued (see Stage 4 in Figure 1.7). The condition report (see Clause 1.15.5) may also contain

acknowledgement of missed tests or outstanding rectification work and if, as a result of this, the fire

protection system is no longer operational, then a failed condition report will result.

together with corresponding systems and equipment sections contained in this standard, are shown in

Table 1.9.

NOTES:

1 Maintenance procedures are not intended to be used as substitutes for commissioning.

2 The recommended maintenance routines for pre-engineered fire protection systems are incorporated in

the manufacturers installation and operation manuals.

C1.9 Construction of building services does not always finish at the time of handover of the

project, resulting in fire protection systems that have not been fully commissioned. The fire safety

services need to be completed and commissioned in order for the results of inspection and test

work to be meaningful.

1.12 SYSTEMS INTERFACE

Where systems are interfaced, such interface shall be tested annually. Annual tests shall take into

account fire protection systems that interface with other systems to permit fire protection systems to

function as intended at the time of commissioning. A systems interface diagram shall be displayed in

the fire control room or centre.

NOTES:

1 See Table 1.12 for an example of a typical systems interface diagram.

2 To limit disruption, it is recommended that the building owner or the building owners representative

coordinate testing of the interfaced fire protection systems. This may require the attendance during

testing of technicians specializing in fire alarms, sprinklers, HVAC, electrical power and control,

building management, etc. Advance notice should be given to the occupants advising of scheduled test

date, procedures and purpose. Fire protection system interface documentation and its accuracy is the

responsibility of the building owner.

3 Automatic sprinkler and fire alarm systems, when activated, may be arranged to automatically cause

operation of the stair pressurization system, release fire doors, operate roof vents to permit products of

combustion to escape, shutdown non-fire essential plant, operate elevator override controls and

automatically cause fire pumpsets to operate.

(d) On completion of defect rectification and minor works, the relevant tests to be conducted in

accordance with the schedules in Sections 2 to 19 to verify that the system has been

successfully reinstated to a fully operational condition.

NOTES:

1 An out-of-service tag system should be used to indicate that the system is temporarily impaired. Tags

should be attached to the affected equipment for the duration of the impairment.

2 During periods when the system is inoperative it is recommended that all fire extinguishing appliances

be held in special readiness for immediate use, and that a watchperson be on duty throughout non-

working hours. Where a water supply from a particular source is curtailed for any protracted period, e.g.,

as in time of drought, special attention should be given to the maintenance of any other water supplies.

3 In the case of multiple installations, each individual installation should be returned to service before

work commences on subsequent installations.

The condition report shall contain acknowledgment of missed maintenance activities or outstanding

rectification work. If the outstanding rectification work results in the fire system or equipment being

no longer operational, such non-operational status shall be noted on the report.

NOTES:

1 The regulatory authority specifies requirements for the certification of essential fire safety measures as

listed in the Building Code of Australia, Section I. A comprehensive list of fire protection systems and

equipment is provided in Appendix E.

2 The regulatory authority may nominate where the report should be located and the form it is to take. In

some cases the building owner is required to furnish an annual fire safety statement for existing essential

fire safety measures.

C1.15.5 The intention of the annual condition report is to facilitate certification of the fire

protection systems and equipment by evaluating the separate processes of inspection, test,

preventive maintenance and survey. It is recognized that different parties may undertake these

processes and provided they have been accomplished in accordance with the requirements

contained in the maintenance schedules in each case, the fire protection systems and equipment

would be eligible for certification.

2.4.1.2 Test and records

Testing of general automatic fire sprinkler systems shall be carried out in accordance with

Table 2.4.1.2. Pumpsets serving sprinkler systems, shall be tested in accordance with Section 3. Prior

to testing, where an alarm signal is to be transmitted, the alarm monitoring service provider shall be

advised that a test is to be conducted. On completion of the test, the alarm monitoring service provider

shall confirm that the system has been restored to normal.

NOTE: The advice may be by configuring the alarm signalling equipment to test mode and confirmation that

the system has been restored to normal by the alarm signalling equipment returning to normal.

Unless required to be operated for the test, the warning system and any ancillary controls, such as

plant shutdown, shall be disabled prior to the test.
