When it comes to electrical and fire safety in homes and strata buildings, working smoke alarms and functioning RCDs (Residual Current Devices) are non-negotiable. In NSW, they’re not just recommended, they’re required by law.
Regular testing is essential for compliance and peace of mind. Whether you’re a homeowner or strata manager in Milsons Point, knowing what is required will protect the people who live there.
Smoke Alarm Compliance in NSW
Smoke alarms are designed to detect fires early, often before residents even realise there’s danger. But for them to do their job, they need to be installed correctly, tested regularly, and replaced when required.
Under Clause 146A of the Environmental Planning and Assessment Act 1979 and the associated Regulation 2000, it is a legal requirement in NSW for all residential buildings where people sleep to have at least one working smoke alarm per level.
This includes:
- Owner-occupied homes
- Rental properties
- Relocatable homes and caravans
- Strata-managed buildings (in both private and common areas, where applicable)
All smoke alarms must meet the Australian Standard AS 3786.
Maintenance Checklist
Stay compliant and reduce false alarms with regular smoke alarm upkeep. These quick checks help ensure your alarms are ready when you need them most.
- Monthly: Press the test button until the alarm sounds. Confirms the battery and sounder are working.
- Every 6 Months: Gently vacuum the alarm with a soft brush attachment to remove dust, cobwebs, or insects that can interfere with detection.
- Every Year: Replace the 9V or removable batteries (if applicable) to ensure a consistent power supply.
- Every 10 Years: Replace the entire smoke alarm unit. Even if it still beeps, the internal sensors degrade over time and may not detect smoke effectively.
Landlord and Strata Responsibilities
Landlords must ensure alarms are installed and functioning at the start of every tenancy. That includes installing fresh batteries in replaceable-battery units and maintaining hardwired systems, including battery backups.
In strata buildings, smoke alarm systems in common areas are often covered under the Annual Fire Safety Statement (AFSS) and must be tested and maintained accordingly.
RCD Testing and Compliance
RCDs are life-saving devices that instantly cut power if they detect even small electrical faults. They reduce the risk of electrocution and electrical fires and are required under AS/NZS 3760:2022 for residential and strata properties.
They work by monitoring the flow of electricity between live and neutral wires. If there’s an imbalance, even a few milliamps, the RCD disconnects power within milliseconds.
How Often Should RCDs Be Tested?
RCDs play a necessary role in electrical safety, and regular testing helps confirm they’ll respond correctly during a fault. Two types of tests are required for full compliance.
Push Button Test
- Frequency: Every 6 months
- Purpose: Ensures the RCD trips when the test button is pressed, confirming it can detect faults
- Who Can Perform It: Homeowners, tenants, or strata managers
- Tip: If the RCD doesn’t trip instantly, it must be checked by a licensed electrician
Timed Trip Test
- Frequency: Every 12 months
- Purpose: Simulates a real fault and measures the time it takes for the RCD to disconnect power
- Who Can Perform It: Only a licensed electrician using specialised test equipment
- Compliance Standard: Must meet trip time thresholds under AS/NZS 3760:2022 (typially 300ms for 30mA RCDs)
Record Keeping
For compliance purposes, every test should be documented with the date, location of the RCD, the type of test, the result, and the technician’s details. This is especially important in strata-managed properties where multiple RCDs may exist across communal and private areas.
Professional Property Protection
Smoke alarms and RCDs only do their job if they’re properly tested and maintained. Without regular checks, you can’t rely on them in an actual emergency. Non-compliance with NSW legislation can carry serious penalties for landlords or strata managers.
