Smoke Alarm Services
Smoke detectors are one of the most important electrical components of your home. So have them installed, replaced and repaired by our experienced, licensed and local Sydney electricians today!
Smoke alarms save lives – so when you require installation, repairs or replacements, you need a licensed and qualified electrician in Sydney.
As you may already know, functional smoke alarms are mandated in all residential and commercial properties across New South Wales. Failing to comply with this rule can invite hefty fines and even jail time, whether you’re the tenant, landlord or property owner. That’s why it’s essential to ensure that the smoke alarms on your property are in working condition to alert the residents of a fire or gas leak and save their lives.
However, there are different types of smoke alarms, and not everyone may know how to use them. Likewise, some smoke alarms may have a separate battery system or be wired into your home’s circuitry to provide backup if the battery fails.
You can ensure your smoke detectors are installed and working correctly by booking a safety inspection. For more information or to book an appointment, call us on (02) 9167-9488 today!
What Is The NSW Law On Smoke Alarms?
Fire and Rescue NSW states that smoke alarms must comply with Australian Standard AS 3786 .
Homeowners
For homeowners, it is required by law that they have a smoke alarm installed on every level of their home . This includes:
- Owner-occupied
- Relocatable homes
- Caravans
- Rentals
- Any residential property where people sleep
Tenants
A landlord must ensure that every property floor has a smoke alarm installed . A tenant must notify the landlord when a smoke alarm requires a replacement battery.
Landlords
If the smoke alarm is not working, landlords and agents must have the alarm repaired within two business days (including replacing the battery). A qualified technician should also inspect all smoke alarms on an annual basis. It is the landlord’s and agent’s responsibility to ensure the following:
- A smoke alarm should be replaced within ten years of manufacture or earlier if the manufacturer specifies.
- Each year (or in the case of lithium batteries, whenever the manufacturer specifies), batteries are installed or replaced.
- Landlords and agents should give at least two business days’ notice and one hour’s notice to inspect or assess smoke alarms for repair or replacement.

What Causes Smoke Alarms To Malfunction?
Some smoke alarms may reach the end of their time, meaning no amount of servicing can revive them. This is when you’d want to replace it with a similar or better model. Most smoke alarms last an average of 10 years, so we recommend changing them every decade.
Aside from that, technical faults in the smoke alarms will cause them to malfunction. Anything from dead batteries to dirt and moisture build-up or internal parts faults can prevent them from beeping or trigger false alarms. Tripping safety switches or power outages affecting your smoke alarms may indicate a deeper electrical issue that requires professional fault-finding at your switchboard or circuit.
It is important to understand that when resolving the more serious issues, the DIY way can invite more troubles if you aren’t aware of the know-how.
You can usually replace the batteries when required and wipe off dirt or moisture outside. However, the best way to keep them optimally functional for prolonged periods is to opt for regular professional maintenance.

Emergency Electrician Sydney
Electrical faults can happen without warning. If your smoke alarm is beeping continuously, not responding, hardwired system has failed, or you notice a burning smell near the unit, you may need an emergency electrician in Sydney straight away.
Hardwired smoke alarms are connected to your home’s electrical system. This means issues such as power failures, tripping circuits, faulty wiring or damaged interconnection can affect multiple alarms at once. In these situations, it is important not to attempt DIY repairs. Electrical work must always be carried out by a licensed professional.
At Pro Electrical, our emergency electricians respond quickly to urgent electrical problems, including:
-
Faulty or non-working hardwired smoke alarms
-
Interconnected alarm system failures

Tripping safety switches linked to alarm circuits
