Your Smoke Alarms Might Be Ready for 2027 – But Is Your Building Ready for a Fire?
Wow — we’re already in September.
Before we know it, Christmas will be here, followed very quickly by 1 January 2027 — an important deadline for Queensland homeowners.
From 1 January 2027, all remaining existing private homes, townhouses and units in Queensland must have compliant interconnected photoelectric smoke alarms installed.
It’s an important change and one that will help improve fire safety in Queensland homes.
But it also raises another important question:
Your smoke alarms can
tell you there’s a fire — but what is helping to contain it?
Smoke alarms play an incredibly important role. They provide early warning, so occupants have the opportunity to respond and evacuate. But in many multi-residential, commercial and other buildings, there is another layer of fire protection working quietly in the background: passive fire protection.
Passive fire systems form part of the building itself and can include fire-rated walls and floors, fire doors, service penetrations, fire collars, fire stopping and other systems designed to maintain fire separation within a building. Unlike a smoke alarm, these systems don't sound an alarm. Their job is to help maintain the fire-resisting performance of the building and limit the spread of fire and smoke where required.
And sometimes, something as simple as installing a new pipe, cable or service can affect that protection.
The Little Hole That Can Become a Big Problem
Imagine a fire-rated wall separating two areas of a building. The wall has been constructed to achieve a particular Fire Resistance Level (FRL), say 1hr.
Later, during maintenance or a renovation, a plumber, electrician, communications contractor or another trade needs to run a service through it.
A hole is created.
The service goes through.
Everyone packs up and goes home.
But was the pene
tration correctly fire-stopped?
Was the correct tested system selected for that particular wall, service and configuration?
Was it installed in accordance with the tested system?
Was it documented?
These details matter.
The National Construction Code specifically addresses openings and penetrations through building elements that are required to resist the spread of fire. Its Performance Requirement C1P8 requires these openings and service penetrations to be protected so that an adequate level of fire performance is maintained.
For service penetrations, the NCC also contains requirements relating to tested systems and references testing under AS 4072.1 and AS 1530.4.
In simple terms:
You can't necessarily put a pipe through a fire-rated wall, fill the gap with something that looks fire-resistant and assume the wall is still compliant.
The entire configuration matters.
Passive Fire Protection Isn't Just About the Product
One of the misconceptions we regularly encounter is that using a recognised fire-stopping product automatically makes an installation compliant.
It isn't necessarily that simple.
The service type, service size, wall or floor construction, penetration size, insulation, orientation, fire-stopping product and installation configuration can all be relevant when determining the appropriate system. This is why passive fire protection needs to be considered throughout the construction and maintenance process, not just at the end when somebody asks for certification.
Once walls and ceilings are closed up, confirming what has actually been installed can become significantly more difficult.
Getting passive fire specialists involved early allows systems and individual layers of construction to be inspected before they disappear behind the finished building.
So, What Can a Passive Fire Audit Find?
A detailed passive fire inspection can help identify and document passive fire systems throughout a property and highlight areas requiring further investigation or rectification.
Depending on the building and scope, this could include items such as:
unprotected or incorrectly protected service penetrations;
missing or unsuitable fire collars;
inappropriate fire-stopping materials;
damaged fire-rated walls or barriers;
fire doors and associated components requiring attention;
undocumented passive fire systems;
installations that do not appear to correspond with the nominated tested system; and
alterations made by other trades that may have affected an existing fire-rated building element.
For existing buildings, AZZO Project Services can undertake a Full Capture Audit to establish a clearer picture of the passive fire systems present throughout the property and identify defects or areas requiring further investigation.
And What About Certification?
Certification is another important part of the process, but it shouldn't simply be treated as paperwork at the end of a project.
For passive systems, appropriate evidence and documentation are important in demonstrating what system was selected, how it was installed and whether the completed installation satisfies the applicable requirements within the scope of the certification.
For contractors dealing with unusual or complicated penetrations, AZZO can also assist with passive fire specifications. This can be particularly valuable when you're dealing with complex combinations of services, substrates and configurations where selecting an appropriate tested system isn't straightforward.
Smoke Alarms and Passive Fire Protection Have Different Jobs
The approaching 2027 smoke alarm deadline provides a good opportunity for property owners to think more broadly about fire safety. A smoke alarm and a passive fire system don't replace one another.
Smoke alarms help warn occupants that there may be a fire.
Passive fire protection helps maintain fire separation and limit the spread of fire and smoke where the building is designed to do so.
Both form part of the bigger fire-safety picture.
So, while you're checking whether your smoke alarms are ready for 2027, it may also be worth asking:
When was the last time somebody looked at the passive fire protection within your building?
If the answer is “I'm not actually sure”, give the team at AZZO Project Services a bell.
We're always happy to pop out, say G'day and have a look at what you've got — then point you in the right direction.
Because there's something pretty comforting about knowing that if the worst happens, the systems designed to protect your building have been properly considered.
