What's included

The actual work involved — spelled out clearly so you know exactly what you're paying for.

Compliant photoelectric alarms

Supply and install of photoelectric smoke alarms to AS 3786 — the type recommended for residential use in NSW because they detect smouldering fires earlier than ionisation units.

240V hard-wired installation

Alarms wired into your home's mains supply with a 10-year lithium backup battery, so a flat 9V battery is never the reason your family doesn't wake up.

Interconnection between units

Every alarm interconnected — when one sounds, they all sound. So a fire that starts in the garage wakes up the kids at the far end of the house.

Correct placement

Alarms installed in every bedroom, in hallways servicing bedrooms, and on every storey — with the mounting and ceiling clearances the standard actually calls for.

Old alarm replacement

Smoke alarms expire after 10 years — we check the date stamp on your existing units and replace anything at or past its use-by, hard-wired and interconnected in the same visit.

Rental property compliance

For landlords: installation and annual testing that meets NSW residential tenancy smoke alarm requirements, with a written record you can hand to your agent.

Testing & handover

Every alarm tested at install, every interconnection checked, and a quick walkthrough so you know how to hush a false alarm without pulling it off the ceiling.

Common questions

In NSW, any home built or substantially renovated since 1997 must have hard-wired smoke alarms. Even in older homes, if you're replacing an existing hard-wired unit or adding one during electrical work, the replacement must be hard-wired and interconnected. It's also the type your insurer wants to see.
