SMOKE ALARM SERVICES

Keep your home safe with compliant smoke alarms.

Working smoke alarms save lives. WA legislation requires all residential properties to have compliant smoke alarms installed and maintained. Our licensed electricians handle everything from new installations to annual testing and battery replacements, ensuring your home meets all regulatory requirements.

WA COMPLIANCE REQUIREMENTS

Understanding smoke alarm regulations

In WA, when a home is sold, made available for rent, or built new or majorly renovated, the alarms must be mains-powered (hardwired), photoelectric, compliant with AS 3786 and no more than 10 years old. Where mains power isn't practical, an alarm with a 10-year non-removable lithium battery can be used instead. Newer builds require interconnected alarms, so when one sounds they all sound.

Whether you're building, renovating, selling or leasing, our licensed electricians (EC16559) assess your home and supply, install and test compliant alarms. Because every property is different, we recommend a free compliance check for advice on your specific home.

HARDWIRED & INTERCONNECTED SYSTEMS

Professional installation for maximum protection

Hardwired smoke alarms are connected to your home's electrical wiring, so by law they must be installed by a licensed electrician. Interconnected alarms — required in newer builds — all sound together the moment one detects smoke, giving everyone the earliest possible warning.

We install photoelectric alarms compliant with AS 3786, positioned on the ceiling on each storey and near the sleeping areas, generally at least 300mm from walls, corners and light fittings. Neat, professional wiring, done right the first time.

TESTING & MAINTENANCE

Annual testing and ongoing maintenance

Smoke alarms should be tested at least once a year and replaced every 10 years. Our service includes functional testing of all units, battery replacement where needed, and checking interconnection between alarms.

For landlords and property managers, we provide compliance reports to satisfy regulatory requirements, ensuring your investment properties stay legally compliant.

Frequently Asked Questions

Otter Air has developed a reputation amongst our clients as being honest, reliable, efficient and provide a professional service that delivers what we promise.

What are the smoke alarm requirements in WA?

In Western Australia, when a home is sold, made available for rent, or built new or majorly renovated, the smoke alarms must be: mains-powered (hardwired) — or, where mains power isn't practical, fitted with a 10-year non-removable lithium battery; photoelectric type; compliant with AS 3786; and no more than 10 years old. Newer builds also require interconnected alarms, so when one sounds they all sound. As your specific property may have its own quirks, we'd recommend a licensed assessment — book a free compliance check and we'll tell you exactly where you stand.

Do smoke alarms have to be hardwired in WA?

In most cases, yes. When a WA home is sold, rented, or newly built or majorly renovated, the alarms must be mains-powered (hardwired). The one exception is where mains power isn't practical — there you can use an alarm with a 10-year non-removable lithium battery instead. Either way they must be photoelectric, compliant with AS 3786, and under 10 years old. We're happy to do a licensed assessment of your home and confirm what's required.

Do I need an electrician to fit or replace a hardwired smoke alarm?

Yes. Hardwired smoke alarms are connected to your home's electrical wiring, so by law they must be installed by a licensed electrician — it's not a DIY job. As licensed Perth electricians (EC16559) we supply, install, replace and test hardwired and interconnected alarms to WA requirements, with a free quote and upfront fixed pricing.

How often do smoke alarms need to be replaced?

Every 10 years. Smoke alarms have a working life of about 10 years from their date of manufacture, after which the sensor becomes less reliable — and WA's rules require alarms to be no more than 10 years old when a home is sold, rented or newly built. We check the age stamped on your alarms during a compliance check and let you know which ones are due.

Where should smoke alarms be installed?

Smoke alarms go on the ceiling on each storey of the home and near the sleeping areas, so everyone is warned in time. To work properly under AS 3786 they're generally kept at least 300mm away from walls, corners and light fittings. We'll work out the right positions and number of alarms for your home's layout as part of the quote.

How much does smoke alarm installation cost?

It depends on how many alarms you need, whether they're hardwired and interconnected, and how easy the ceiling and wiring access is. Rather than guess, we give you an exact, upfront price at a free site visit — so you know the full cost before any work starts.
