Service Overview
Why Smoke Alarm Compliance Matters on the Central Coast
Smoke alarms are the cheapest and most effective piece of life-safety equipment in any home — and they are the most commonly overlooked. NSW law requires a working smoke alarm on every level of a residential building, and for rental properties the compliance requirements are stricter still. A dead battery, a unit past its expiry date, or an alarm installed in the wrong location can turn a life-saving device into an ornament.
Modern NSW guidance leans strongly toward photoelectric, interconnected, mains-powered smoke alarms with a 10-year sealed battery. Interconnection matters more than most people realise: when one alarm detects smoke, every alarm in the property sounds, which is the difference between waking up to a fire at the other end of the house and not waking up at all.

“Power went out across half the house during a storm. AB Electrical came out the same evening, found the fault in the switchboard, and had everything back on within two hours. Good communication throughout and fair pricing for after-hours work.”

“Smelled burning near a powerpoint and called AB straight away. They talked me through turning off the circuit over the phone and were at the house within 40 minutes. Turned out to be a loose connection arcing behind the wall plate. Fixed properly and checked the rest of the circuit too.”

FAQs
Questions about smoke alarms
NSW requires photoelectric smoke alarms that are interconnected so that when one alarm detects smoke, all alarms in the property sound. Mains-powered alarms with a sealed 10-year lithium battery are preferred for new installations. Ionisation-only alarms are no longer recommended because they are slower to respond to smouldering fires.
Yes in most residential properties. NSW requires interconnected alarms so all units in the property activate together when one detects smoke. This is the difference between waking up to a fire at the other end of the house and not waking up at all. AB Electrical installs interconnected systems as standard.
Smoke alarms have a 10-year life from the date of manufacture. After 10 years the sensor degrades and the alarm must be replaced — even if it still beeps when tested. The manufacture date is printed on the back of the unit. AB Electrical checks the date during every smoke alarm visit.
Yes. A compliance certificate is issued on the same day as the installation and sent directly to the landlord or property manager. AB Electrical also provides documentation suitable for rental records, insurance, and council requirements.
Yes. Pre-settlement smoke alarm compliance is a common job. AB Electrical can typically complete the work within a few days of the enquiry, with the compliance certificate supplied the same day as the installation so settlement is not held up.
NSW requires a working smoke alarm on every level of a residential building, in hallways or areas leading to bedrooms, and in each bedroom for rental properties depending on the tenancy agreement date. AB Electrical assesses the property and confirms the correct placement during the quote visit.
A typical 3-bedroom Central Coast home with interconnected photoelectric alarms runs $750 to $1,400 depending on the number of alarms, whether existing wiring is in place, and ceiling access. Single alarm replacements are $150 to $260. Every job is quoted in writing before work starts.
