Smoke alarms save lives, but only if they work. Every NSW home must have working smoke alarms, and landlords have extra obligations to keep them in working order. Alarms also wear out: most manufacturers say to replace them every ten years.
We install hard-wired alarms, replace old and faulty ones, and set up interconnected systems so that when one alarm sounds, they all do. That matters most in two-storey homes and bedrooms at the other end of the house.

Smoke alarms: FAQs
How often should smoke alarms be replaced?
Most manufacturers recommend replacing smoke alarms every ten years. The date is usually printed on the back of the alarm. If you cannot find it, it is probably time.
What does interconnected mean?
The alarms are linked, so when one detects smoke, every alarm in the house sounds. It gives you far more warning, especially if a fire starts away from the bedrooms.
I am a landlord. Can you check our rental?
Yes. We test the alarms, replace any that are faulty or out of date, and give you a record of what was done.
