A fire sprinkler system is one of the most effective pieces of fire protection a building can have. It works automatically, it responds at the source of the fire, and in most cases it controls or extinguishes a fire before the fire brigade arrives. But a sprinkler system that has not been tested properly is a system you are trusting on faith.
Closed valves, corroded pipework, painted-over heads, and low water supply pressure can all leave a sprinkler system unable to do its job, and none of them are visible from the floor. The only way to know your system will perform is to test it at the intervals Australian Standards require.
This guide explains what sprinkler testing involves, how often it must happen, what commonly goes wrong, and how it connects to your Annual Fire Safety Statement.

Two Australian Standards matter when it comes to sprinkler systems, and building owners often confuse them.
AS 2118 covers the design, installation, and commissioning of automatic fire sprinkler systems. It has several parts for different building types. AS 2118.1 covers general commercial systems, AS 2118.4 covers sprinklers in residential and accommodation buildings, and AS 2118.6 covers combined sprinkler and hydrant systems.
AS 1851 covers the routine servicing of those systems once they are installed. It sets out what must be inspected and tested, how often, and what must be recorded. This is the standard that drives your ongoing maintenance obligations.
From 13 February 2026, compliance with AS 1851-2012 is mandatory in NSW for all Class 1b and Class 2 to Class 9 buildings. In practical terms, AS 2118 tells you how the system should have been built, and AS 1851 tells you how you must keep it performing as built.

Sprinkler testing is layered. A single annual visit is not enough. AS 1851 sets out checks at monthly, six-monthly, annual, five-yearly and longer intervals, and the exact tasks depend on the type of system installed (wet pipe, dry pipe, deluge, or pre-action).
Monthly Basic checks to confirm the system is ready to operate. This includes confirming that control valves are open and secured in the correct position, checking water supply gauges and system pressure, and checking that the sprinkler pumpset (where fitted) starts and runs correctly.
Six-Monthly More detailed inspections, including testing of alarm devices and flow switches, checks on water supply connections and booster assemblies, and inspection of visible pipework, hangers, and sprinkler heads for damage, corrosion, or obstruction.
Annual A comprehensive test of the whole system. This includes flow and pressure testing to confirm the water supply can deliver what the system was designed to deliver, testing of alarm valves and associated alarms, and comparing current readings against the baseline data recorded at commissioning. Generic records without measured values are not enough. Documentation must show the actual readings taken.
Five-Yearly and Beyond Intensive assessments of the internal condition of pipework, valve overhauls, and sampling of sprinkler heads for testing. Further tasks fall due at ten-yearly intervals and out to thirty-yearly intervals, depending on the system type and the age of the installation. These long-cycle tasks are the ones most often deferred until they become urgent, so they need to be mapped into your maintenance program well in advance.
All testing must be carried out by a competent person and recorded in a hard copy logbook that stays on site after every service visit. In NSW, records must be retained for a minimum of seven years and made available to the Fire Commissioner or local council on request.
Long-cycle sprinkler tests are easy to miss. Fire Safe ANZ maps every AS 1851 interval for your building so nothing falls through the gaps. Get in touch
Building owners often picture sprinkler testing as a technician walking the floor and looking up. The reality is more involved. Depending on the interval, a sprinkler service may include:
Every one of these checks produces a result that must be recorded, with a clear pass or fail outcome and a note of any defect and the action required.
Sprinkler defects tend to be mundane, and that is exactly why they are so often missed. The issues we see most often include:

Sprinkler systems are listed as essential fire safety measures on the fire safety schedule of most commercial and multi-residential buildings. For your Annual Fire Safety Statement to be valid, every measure on the schedule must have been inspected, tested, and found to be performing to the required standard within the three months before lodgement.
From 13 February 2026, your accredited practitioner will also check that your maintenance records demonstrate compliance with the AS 1851 intervals across the whole year, not just that the system looks fine on the day. A missed monthly check or an overdue five-yearly test is a records gap, and a records gap can stop the AFSS from being endorsed.

The building owner holds responsibility for ensuring the sprinkler system is maintained in accordance with AS 1851. In a strata building, the owners corporation is the building owner. In a leased commercial building, the lease should clearly set out who arranges and pays for base building system testing and who is responsible for tenancy-level changes that can affect the system.
Engaging a contractor does not transfer legal responsibility. If the contractor does not carry out a required test or does not record it properly, the liability still rests with the owner. That is why it matters to choose a provider who understands the standard and documents every visit.
