Smoke Alarm Services

In NSW, smoke alarm requirements have been updated — older ionisation alarms must be replaced with photoelectric alarms, and hardwired interconnection is required in new builds and major renovations. PrimeTime Electrical handles the full scope: installation, interconnection, testing, and replacement of expired 10-year alarms.

New Smoke Alarm Installation

Supply and install photoelectric smoke alarms in the correct locations — bedrooms, hallways, and living areas — to meet NSW Building Code requirements.

Alarm Interconnection

Hardwired interconnection of multiple alarms so all units sound together when one detects smoke — the safest configuration for multi-room and multi-storey homes.

10-Year Replacements

All smoke alarms have a 10-year service life. We supply and install compliant replacements when your existing alarms expire, restoring full protection.

Testing & Certification

Annual testing, battery replacement, and a compliance certificate — ideal for landlords, property managers, and investors who need documented proof of working alarms.

Rental Property Compliance

Landlords in NSW are legally required to ensure smoke alarms are working. We handle the installation and testing and provide the documentation you need before a tenancy.

Ionisation to Photoelectric Upgrades

Replace outdated ionisation-type alarms with modern photoelectric units that meet current NSW standards and respond faster to slow, smouldering fires.

NSW Smoke Alarm Requirements

Under NSW legislation, all homes must have working photoelectric smoke alarms on every level, including in each bedroom and in hallways connecting bedrooms to the rest of the house. Ionisation alarms are no longer compliant. New builds and major renovations require hardwired interconnected alarms. Landlords must ensure alarms are tested and working before a new tenancy begins and within 30 days of a tenancy renewal.

Photoelectric vs Ionisation Alarms

NSW now requires photoelectric alarms. Here's why the distinction matters:

Ionisation Alarms (outdated)

  • Detect fast-flaming fires quickly
  • Slower to detect slow, smouldering fires
  • More prone to nuisance trips from cooking
  • No longer compliant in NSW
  • Must be replaced when they expire

Photoelectric Alarms (required)

  • Detect slow, smouldering fires earlier
  • The type of fire most common in homes at night
  • Fewer nuisance alarms from cooking steam
  • Required under current NSW standards
  • 10-year sealed battery or hardwired options

Our Smoke Alarm Installation Process

1
Site Assessment

We walk through your home and identify every location where a compliant alarm is required — bedrooms, hallways, and living areas across all levels.

2
Existing Alarm Check

We check the type, age, and condition of your current alarms. Any ionisation-type or expired units are flagged for replacement.

3
Supply & Installation

We supply and install compliant photoelectric alarms in all required locations — ceiling mounted, positioned away from cooking areas to minimise false alarms.

4
Interconnection Wiring

Where interconnection is required or requested, we run the wiring between alarms so all units trigger simultaneously when any one detects smoke.

5
Full System Test

Every alarm is tested before we leave — activation test, battery check, and interconnect test to confirm all units trigger together.

6
Certificate of Compliance

A Certificate of Compliance for Electrical Work (CCEW) is issued on completion — essential for landlords, insurance, and property sales.

Smoke Alarm FAQs

Do I need a licensed electrician to install smoke alarms?

Hardwired smoke alarms must be installed by a licensed electrician. Battery-operated alarms can be self-installed, but for landlords and property managers, having a licensed electrician install and certify all alarms provides the documentation required to demonstrate compliance.

How many smoke alarms do I need in my home?

NSW requires at least one working smoke alarm on every level of the home, in each bedroom, and in every hallway connecting bedrooms to the rest of the house. The exact number depends on the layout of your property — we assess each home individually.

My smoke alarm keeps beeping — what does that mean?

A low-battery warning is the most common cause of a chirping alarm. However, if your alarm is more than 10 years old, it may need full replacement rather than just a battery swap. We can inspect, test, and replace alarms that have reached end of life.

I'm a landlord — what are my smoke alarm obligations in NSW?

Landlords must ensure smoke alarms are installed in required locations, are photoelectric type, are in working order, and have their batteries tested before a new tenancy begins and within 30 days before a tenancy renewal. We handle the installation, testing, and certification and provide the paperwork you need.

Do alarms need to be interconnected?

Interconnection is required for new builds and major renovations under the NSW Building Code. For existing homes, interconnection is not always mandatory but is strongly recommended — especially in multi-storey homes — so that an alarm on one level will alert the whole house.

How long do smoke alarms last?

Smoke alarms have a maximum service life of 10 years from the date of manufacture. After this point they must be replaced regardless of whether they still appear to function. The manufacture date is printed on the back of the unit.
