Emergency Lighting Requirements

Emergency lighting in Australian commercial buildings must provide sufficient illumination for occupants to identify and follow a safe route when the normal lighting supply fails. The NCC determines where emergency lighting and exit signs are required, while the applicable AS/NZS 2293 editions govern design, installation, commissioning and routine servicing. The exact requirements depend on the building and its approvals.

Commercial emergency and exit lighting must match the building’s approved design, operate automatically during power failure, remain effective for the required duration and be routinely tested. Owners should verify the NCC pathway, fire safety schedule, applicable standards, current layout and maintenance records rather than relying only on whether fittings illuminate.

Together, they support safe evacuation rather than providing normal workplace lighting.

Ordinary lights generally go out when their circuit or the building supply fails. Self-contained emergency lighting has a local battery and charging arrangement, while a centrally supplied system draws emergency power from a central source. In either case, changeover must occur without occupants having to find a switch.

The Australian Building Codes Board describes the NCC as Australia’s primary set of technical design and construction provisions. NCC Volume One contains the requirements relevant to most Class 2 to 9 buildings, including emergency lighting and exit signs. The NCC sets the circumstances in which these measures are required and references technical standards used to deliver them.

Building classification, number of floors, floor area, use, paths of travel and fire-isolated exits can all change the answer.

A small single-storey tenancy and a multi-storey office, shopping centre, warehouse, hotel or healthcare building should not be assessed from the same generic checklist. The starting point is the approved building documentation, relevant construction certificate or approved fire safety schedule where one exists. For existing buildings, the legally applicable standard may be the one nominated when the work was approved, not automatically the newest edition now available.

The important practical point is that the NCC establishes the need and scope, while AS/NZS 2293.1 provides the technical design, installation and commissioning framework. AS/NZS 2293.1 should not be used in isolation to decide whether a particular space requires emergency lighting.

Emergency lights and exit signs must be positioned so occupants can recognise an exit and safely negotiate the approved path of travel when normal lighting is unavailable.

This commonly includes required exits, corridors, stairs, ramps, passageways, changes of direction or level and other nominated spaces, but compliant placement requires a building-specific design review.

An exit sign above a door is useful only if people can see it from the approach and understand where it leads. Directional signs may be needed where the exit itself is not readily apparent. Emergency illumination must also address the route between the occupied space and the exit, including locations where a person could trip, take a wrong turn or enter a dead end.

In practice, nominal spacing alone does not prove adequate coverage. Ceiling height, lighting performance, wall geometry, shelving, equipment, smoke barriers and the route occupants will actually take all matter. A drawing-based review should therefore be reconciled with a site inspection.

A compliant evacuation arrangement often needs both because seeing a green sign does not illuminate stairs or obstacles, while general emergency illumination does not necessarily tell an occupant which door is the correct exit.

Exit signs must remain visible and unambiguous from relevant approach directions. An incorrect arrow can be more dangerous than a failed sign because it confidently sends occupants the wrong way. Signs and luminaires may be self-contained or connected to a central emergency supply, but their charging, changeover and sustained operation still need to be demonstrated.

The standards Australia’s catalogue describes AS/NZS 2293.1:2018 as specifying requirements for the design and installation of emergency lighting and illuminated emergency exit signage systems. Standards Australia also identifies it as a primary referenced document in NCC 2022 and explains that it is intended to provide acceptable illumination in nominated areas for safe evacuation.

AS/NZS 2293.3:2026 is the current product standard in the Standards Australia catalogue and specifies requirements for the design, construction, performance and testing of emergency luminaires and exit signs. A new publication date does not, by itself, prove that edition has been adopted for every existing installation or approval.

Owners should ask a competent practitioner to identify the approved standard of performance before scoping work. Applying a current standard as an upgrade benchmark can be sensible, but it should not be confused with determining the legal basis of an existing building without reviewing its documentation.

It must also be capable of being safely tested, maintained and identified throughout its service life.

Design work considers the location and output of luminaires, mounting height, spacing, stair and ramp conditions, changes in direction, sign viewing distance and orientation. It also considers the electrical arrangement, local battery-backed fittings or a central supply, the circuits monitored for failure, charging arrangements and test facilities.

Accessibility is often underestimated. If a test switch cannot be operated without disrupting unrelated services, if fittings cannot be safely reached, or if assets are not labelled consistently with the register, routine maintenance becomes slower and less reliable. Good handover information should include approved drawings, product details, circuit information, test arrangements, commissioning results and an asset schedule.

One of the most common problems is not a defective component but missing baseline information. Without knowing the approved layout and performance standard, a contractor can replace failed batteries yet miss signs facing the wrong way, new partitions blocking visibility or an entire route that is no longer adequately covered.

Emergency fittings should automatically change to their emergency supply when the relevant normal supply fails.

They must then deliver the required performance for the applicable operating period, illumination at the first moment of failure is not proof that the fitting will remain effective throughout a discharge test.

Batteries age through time, temperature and repeated cycling. A fitting may illuminate brightly for several minutes but dim or extinguish well before the end of the required period. Charging faults can also leave a new battery undercharged. That is why a brief functional test and a full-duration discharge test answer different questions.

After power is restored, the system must return to its normal state and recharge. The service provider should confirm that normal supply has been reinstated, identify fittings that did not recover correctly and manage the period in which discharged batteries have reduced reserve capacity.

One generic interval should not be treated as the complete maintenance program.

Since 13 February 2026, the NSW Government requires installed essential fire safety measures to be maintained in accordance with AS 1851-2012 unless an approved Performance Solution specifies otherwise. NSW guidance also requires maintenance records to be retained on site for at least seven years. This is a NSW requirement and should not be represented as a uniform national rule.

The relationship between AS 1851 and AS/NZS 2293.2 should be checked for the particular jurisdiction and building documentation. Owners should not assume that engaging a contractor for a single six-monthly visit automatically satisfies every applicable inspection, maintenance, record-keeping and certification obligation.

The process must be planned so the building remains safely occupied and the emergency reserve is managed while batteries recharge.

Before testing, the provider should identify the test zones, advise affected occupants, consider natural light and business operations, and confirm that isolating the supply will not inadvertently disrupt unrelated critical equipment. During the test, each asset is checked for correct changeover, illumination and sustained operation. Failed, dim, damaged or incorrectly operating fittings are recorded individually.

At completion, normal power is reinstated and charge indicators and test controls are checked. The provider should issue results that identify each failed asset and the nature of the defect, rather than a vague statement that “some lights failed”. Where the premises cannot safely operate with depleted batteries, testing may need to be staged or scheduled outside normal hours.

The most common failures are weak batteries, failed light sources, charging faults, damaged fittings and systems that no longer match the tenancy layout.

Documentation defects are equally important because an unlabeled asset or missing approved plan makes it difficult to prove that the whole system, not just the visible fittings, have been assessed.

Replacing a battery is appropriate when the battery is the cause and the fitting remains serviceable. It is not a universal remedy. Repeated battery failures may indicate heat, charging or product issues, while obsolete fittings may be more reliably replaced as complete units.

New partitions, doors, racking, displays, ceilings or a change of use can obscure signs, create additional turns and leave the installed system inconsistent with the approved evacuation path.

We regularly see a technically working sign pointing towards a door that is no longer an exit, or a new corridor with a dark change of direction. Ceiling contractors may relocate a light to suit services without checking photometric coverage. Retail displays and warehouse racking can block a sign that was clearly visible when the building was approved.

Simply adding one fitting at the most obvious dark spot may not resolve the problem. A competent review should trace the whole route, verify the applicable design basis, assess sign visibility, illumination and update the drawings and asset register.

Delegating administration does not necessarily transfer the owner’s statutory responsibility.

Lease documents may allocate day-to-day costs or require a tenant to maintain equipment within a tenancy, but responsibilities at tenancy boundaries often become unclear. A practical compliance plan should state who arranges tests, who receives reports, who approves repairs, who verifies closure and who keeps the building-wide records.

Electrical work must be performed by appropriately licensed people under the relevant state or territory regime. Routine testing also requires competence in the applicable NCC and AS/NZS 2293 framework. In NSW, statutory assessment functions for fire safety statements must be undertaken by an accredited practitioner where the legislation and approved accreditation scheme require it (NSW Gov).

Outstanding failures, incomplete records or uncertainty about the approved design can delay endorsement.

NSW Planning states that an Annual Fire Safety Statement is issued each year, covers all essential fire safety measures applying to the building, and confirms that an accredited practitioner has assessed, inspected and verified each measure’s performance. It also confirms inspection of the building’s exit systems. These requirements are specific to NSW, other states and territories use different certification and enforcement arrangements.

The AFSS should be the end of a maintained annual process, not the first time defects are investigated. Owners who wait until the due date can find that replacement parts, access arrangements, design clarification or a full discharge retest cannot be completed quickly enough.

Repeated battery failures, obsolete fittings, unavailable parts, damaged wiring, inadequate coverage and missing test functions are common triggers.

Required rectification should be separated from optional modernisation. A failed fitting must be restored to compliance; installing a networked monitoring system may be an operational improvement rather than a statutory necessity. Monitored systems can improve asset visibility and testing efficiency in larger portfolios, but they do not remove the need for correct design, physical inspection, defect management and records.

Where baseline documentation is poor, owners should consider combining replacement works with verified drawings, labels and an asset register. That investment often reduces future testing uncertainty and makes quotations, defect tracking and certification more transparent.

This avoids paying to replace components while leaving design, documentation or route defects unresolved.

The provider should be able to test safely, report asset-level results and recognise layout or design problems rather than only replace batteries.

Ask how the provider will identify each fitting, record the full duration test, manage occupied areas and confirm restoration of normal supply. For rectification work, ask whether the scope includes commissioning, updated labels, drawings and a clear distinction between mandatory defects and optional improvements.

Experience in occupied commercial buildings matters. Testing can affect trading areas, lifts and corridors, and it temporarily depletes emergency batteries. Good providers plan access and disruption, communicate failures clearly and leave the owner with evidence another practitioner can understand.

Emergency lighting compliance is best managed as a complete lifecycle: establish the approved requirement, keep the installed layout aligned with the building, test sustained performance, rectify defects and retain usable evidence. If the system has poor records or has been altered through successive fit-outs, a coordinated layout and documentation review is usually more valuable than another round of isolated battery replacements.
