A licensed electrician must install all hardwired alarms.

When Your Smoke Alarms Need Replacing or Upgrading

Alarm is more than 10 years old

All smoke alarms must be replaced within 10 years of their manufacture date (printed on the back of the unit). After 10 years the sensor degrades and may not detect smoke reliably. This applies to all NSW properties — rental or owner-occupied.

Ionisation alarms installed

NSW requires photoelectric alarms complying with AS 3786:2014. Ionisation alarms — which react to flaming fires but are slow to detect smouldering fires (the most common type in residential fires) — do not comply. They must be replaced with photoelectric units.

Battery-only alarms in a post-1997 home

Homes built after 1 August 1997 require 240V hardwired smoke alarms — battery-only units are not compliant. For homes built after 1 May 2014, alarms must also be interconnected so all alarms sound simultaneously when one is triggered.

Alarm chirping or failing to test

An alarm that chirps intermittently (not a full alert) has a low battery or a failing sensor. An alarm that doesn’t sound when its test button is pressed must be replaced immediately. Under NSW rental law, faulty alarms must be repaired or replaced within 2 business days of notification.

New tenancy commencing

Under the Residential Tenancies Regulation 2019, landlords must ensure smoke alarms are in working order before a new tenant moves in — not after. Non-compliance with smoke alarm obligations carries fines of up to $2,200 per breach. Get them sorted before the tenancy, not during.

How electricians install them

Hardwired smoke alarm installation requires a licensed electrician. Each alarm is connected to a dedicated 240V lighting circuit and, for interconnected systems, linked via data wire (or wireless radio frequency) so all alarms sound when one detects smoke.
