How Much to Install a Fire Alarm System in Australia
From Homes to Offices: Fire Alarm Installation Costs You Should Know
In 2025, fire safety is no longer an afterthought—it’s a legal and essential part of protecting homes and businesses across Australia. Whether you're moving into a new property, upgrading an outdated system, or building from scratch, the big question remains: how much to install a fire alarm system?
It’s a fair question, especially when pricing can vary widely depending on property type, system complexity, and installation standards. In this detailed breakdown, SCAVI shares practical insights into current fire alarm system pricing across Sydney—from residential apartments to commercial buildings, and what’s actually included in a professional install.
Factors That Influence the Cost of Fire Alarm System Installation
Type of Property – Residential vs. Commercial Needs
The cost of installation often comes down to the kind of space being protected. A standalone three-bedroom home will need far fewer devices than a strata complex or a warehouse with multiple access points. Homes usually require smoke detectors in living areas and bedrooms, while commercial sites must consider evacuation plans, fire panels, and zone coverage.
As a result, installing a fire alarm system in an industrial or office setting involves more engineering, more hardware, and stricter compliance—driving up the cost compared to a simple household job.
Type of Fire Alarm System – Conventional, Addressable, or Wireless
Conventional systems are basic but affordable. Addressable systems, while more expensive, offer pinpoint accuracy—identifying exactly where the smoke is coming from. Wireless systems save on cabling but might cost more per device.
In general, the more advanced the system, the higher the upfront cost. But complexity often adds long-term value, especially when easy maintenance and expansion are factored in.
Number of Devices Required – Detectors, Panels, Call Points, Sounders
Another major price driver is how many components your system needs. A small unit might only need two alarms. A three-storey office could require a dozen smoke detectors, a control panel, call points at exits, and multiple sounders.
The more extensive your system, the more time and hardware will be required—this affects both material and labour costs.
Installation Labour and Compliance Requirements in Australia
In Sydney, professional fire alarm installation must comply with AS 1670 and AS 1851. Hiring licensed technicians isn’t just a recommendation—it’s the law in many cases, especially for hardwired systems or any commercial property. Costs can also include commissioning reports, testing tags, and documentation for council or insurance purposes.
Average Fire Alarm System Pricing in Sydney – A 2025 Guide
Cost Range for Residential Installations in Sydney
For a standard residential setup in Sydney, costs generally start around $300–$800 for a basic system. If you're opting for a smart or interconnected system—especially with mobile notifications and cloud integration—the price can rise to $900–$2,000.
These figures may also vary depending on whether you're installing one or multiple alarms, the type of property (e.g., apartment vs. detached home), and the accessibility of the installation site.
Cost Breakdown for Commercial Fire Alarm System Installations
Commercial installations come with a broader price range. Offices, shops, or small restaurants may expect to pay $2,500–$10,000, depending on coverage needs. Larger buildings, such as factories or schools, may see costs well above $10,000, even reaching $50,000+ for multi-zone or complex evacuation systems.
These estimates include not only equipment but also system design, documentation, and emergency planning integrations.
Comparison: Wired vs. Wireless System Costs
Wired systems are often cheaper per device but may require expensive and invasive cabling—especially in older or multi-level buildings. Wireless alarms cost more up front but can be more flexible for installations in heritage sites or temporary structures.
Maintenance costs are usually lower with hardwired systems, but wireless ones can be easier to relocate or upgrade.

Saving on Fire Alarm Installation – What You Should Know
Government Grants and Safety Rebates in Australia
Depending on your state or region, you may be eligible for fire safety upgrade assistance. NSW, for instance, has run community grant programs for residential fire safety, while some business energy-saving schemes include fire alarm upgrades. SCAVI can help identify if any apply to your situation.
DIY vs. Professional Installation – Is It Worth It?
You might be tempted to install your own battery-powered alarm—and in some cases, that's fine. But for full systems, interconnected devices, or anything involving wiring, a professional is not just safer—it’s usually required.
Incorrect installation can void insurance, create hazards, or lead to council fines.
Choosing the Right Installer – What to Ask Before Hiring
Ask your installer if they’re licensed, insured, and experienced with similar properties. Always request a quote that breaks down what’s included—hardware, labour, compliance documents, and follow-up services.
