An RHIS (Residential Hearing Impaired Solution) pairs a high-intensity strobe light with a vibrating pad placed under the mattress or pillow. When the interconnected alarms detect smoke, the strobe flashes and the pad vibrates — alerting someone who can't hear the siren. Fitted and tested by a Master Electrician. Read our full guide →

In Queensland, you need a photoelectric, interconnected smoke alarm in every bedroom, in hallways connecting bedrooms, and on every storey of the home. As a rule of thumb, that's one alarm per bedroom plus one per level — with an extra alarm where bedrooms are split into separate wings.
| Home size | Typical alarms needed |
|---|---|
| 1-bedroom unit | 2 |
| 2-bedroom, single storey | 3 |
| 3-bedroom, single storey | 4 |
| 4-bedroom, single storey | 5 |
| 4-bedroom, double storey | 6 |
| 5-bedroom, double storey | 7 |
These are typical minimums — your exact number depends on your floor plan. Use the calculator above for a figure tailored to your home, or call us on 0418 416 481.

Every Queensland home — including owner-occupied — must have compliant alarms. Rentals and homes being sold or leased have been required since 2022.
In every bedroom, in hallways connecting bedrooms to the rest of the home, and on every storey — even levels without a bedroom.
Photoelectric (AS 3786:2014) and interconnected — when one sounds, they all sound. Either 240V hardwired or a non-removable 10-year lithium battery.
Penalties apply under the Fire and Emergency Services Act, and insurers may reduce or reject claims if alarms were non-compliant at the time of a fire.
We fit the Red Professional range as standard — proudly Australian-owned and based right here on the Sunshine Coast at Chevallum, designing alarms "by electricians, for electricians." Every unit is photoelectric, certified to AS 3786:2014, and backed by a market-leading 10-year warranty across the entire range, serviced locally in Australia. A quality local product, fitted by your local Master Electrician — it's the gear we trust in our own customers' homes.
Backed across the entire range and serviced 100% locally in Australia — not throwaway hardware.
Certified to AS 3786:2014 and ready for the Queensland 2027 interconnected smoke alarm laws.
10-year sealed wireless RF units, or 240V hardwired with an RF module — whichever suits your home.

Yes. Every alarm must be interconnected so that when one detects smoke, all of them sound — giving everyone in the home the earliest possible warning. Interconnection can be hardwired or wireless.
Either is compliant. If your home already has 240V hardwired alarms, we typically replace them with hardwired photoelectric interconnected units. If not, 10-year sealed wireless interconnected alarms avoid wiring and wall damage. We'll recommend the best option for your home.
It isn't legally required, but we recommend adding an interconnected detector in the garage if you charge batteries or store charging devices there — so any fire triggers every alarm in the home for the earliest possible warning.
A typical 3-bedroom single-storey home needs about 4 interconnected photoelectric alarms — one in each of the three bedrooms and one in the connecting hallway. A double-storey 3-bedroom home usually needs 5. Use the calculator above for your exact number.
A 2-bedroom single-storey home or unit typically needs 3 alarms — one in each bedroom and one in the hallway connecting them. If the bedrooms sit at opposite ends, you may need an extra hallway alarm.
Yes. Every installation includes testing and a compliance certificate, so you have documented proof your home meets the Queensland legislation — important for owners, landlords and sellers.
