Why a working smoke alarm matters for your family
A working smoke alarm can give your family early warning and time to get out if a fire starts, especially while everyone is asleep. If an alarm chirps persistently, fails a test, stops working after ceiling work or has passed its replacement date, arrange a check promptly. We can check the unit and its electrical connection, then explain whether it needs replacing or the installation needs other attention. Do not leave a faulty alarm disconnected while waiting for an assessment.
Placement and coverage
The right number and position of alarms depend on your home’s layout and applicable requirements. Fire and Rescue NSW encourages wider coverage than the minimum legal position, including interconnected alarms where possible. We review the existing units and rooms before recommending any additional positions, so separated sleeping and living areas are considered together.


Hardwired and interconnected alarms
The existing supply and the way alarms warn people throughout the home both affect the installation.
Replacing hardwired alarms
If your home already has hardwired alarms, a replacement needs to work with the existing supply and connection. Send a photo of each model label and tell us where the units are installed. Replacing one faulty alarm may involve different work from updating several. We will inspect the current installation and explain which replacement units and electrical work are suitable.
Interconnected warning
Interconnected alarms sound together when one unit detects smoke, helping the warning reach separated parts of a home. The method of interconnection and available power supply shape the installation. Tell us whether the current alarms already sound together and where the sleeping and living areas are. We can review the existing layout and discuss how additional or replacement units would fit with it.
Testing and ongoing upkeep
Fire and Rescue NSW advises residents to test smoke alarms monthly using the test button and replace alarms when they reach the end of their service life. Follow the manufacturer’s instructions for the models in your home. If an alarm still faults after routine maintenance, arrange an assessment rather than ignoring it. A working system depends on the units continuing to operate after installation, not merely being fitted to the ceiling.
