Smart Smoke Detector for Australian Homes

9 December 2022

A smart smoke detector does what a standard alarm can't: it tells you there's a fire even when you're not home, and the best ones intervene before the smoke becomes flame. That's the difference between coming home to a burnt dinner and coming home to a burnt house. This guide covers what makes an alarm smart, what to look for when buying one, and the compliance rule that catches most Australian buyers out.

What makes a smoke detector "smart"?

A traditional smoke alarm does one thing: it sounds when it detects smoke. If nobody's home to hear it, it sounds anyway, to an empty house.

A smart smoke detector adds connectivity. It can send an alert to your phone wherever you are, link with other alarms so they all sound together, and in the best case, act on the problem rather than just announcing it. The Innohome Smart Smoke Alarm is a good example of that last point: it connects to your home's electrical circuit and, when it detects smoke, switches off the power. If a faulty appliance is smouldering, the alarm doesn't just wake you, it cuts the power feeding the fault.

That's the practical case for smart. An early warning is useful. An early warning plus an automatic intervention is better.

The compliance rule most buyers miss

Here's what catches people out, and it matters more than any feature list. In Australia, a smoke alarm must comply with Australian Standard AS 3786. Plenty of imported smart alarms sold online look impressive and are not certified to that standard, which means installing one may leave you legally non-compliant even though your house is full of gadgets.

Under NSW legislation, every home needs at least one working smoke alarm on every level, in hallways near bedrooms, and each unit must meet AS 3786. A smart alarm can absolutely satisfy that, but only if it's certified. Check for the AS 3786 marking on the body of the unit before you buy, not after.

Fire and Rescue NSW's smoke alarm buyers guide is worth reading before you spend anything, and it recommends hard-wired, interconnected alarms wherever possible.

What to look for in a smart smoke detector

Features vary wildly, and not all of them matter. The ones that do:

AS 3786 certification. Non-negotiable. Without it, the alarm doesn't meet Australian requirements no matter how clever it is.
Photoelectric sensing. Photoelectric alarms detect slow, smouldering fires faster, the kind that start in wiring or furnishings and kill people in their sleep. Fire authorities across Australia now favour them.
Interconnection. When one alarm detects smoke, all of them sound. A fire starting in the garage should wake the people asleep at the other end of the house.
Phone alerts. Useful when the house is empty, when you're travelling, or when you're managing a rental or an aged care facility from a distance.
Power cut-off. Rare, and genuinely valuable. An alarm that kills power to the circuit causing the smoke stops the fire at the source rather than waiting for someone to arrive.
A 10-year sealed battery. No annual battery changes, and no temptation to pull the battery out during a false alarm.

A smart alarm for the home

The Innohome Smart Smoke Alarm is the unit we'd point most households at. It's compact, straightforward to install, interconnects with other alarms, sends alerts, and cuts the power when it detects smoke from an electrical fault.

It suits renters and apartment dwellers who can't rewire anything, and it's a practical fit for aged care and shared accommodation, where a phone alert to a manager matters as much as a siren in the hallway.

Smart detectors on a worksite

If you're protecting a construction site or a commercial space rather than a house, the equipment is different. The Cygnus CYG44 smoke detector connects to the Cygnus wireless alarm panel, has a built-in heat detector and an 85dB siren, and runs on a lithium battery with backup. The Orisent smoke detector uses Bluetooth to push alerts through a smartphone app and integrates with site sirens and triggers.

Both are site systems, not household products, and they're designed to be installed to local and state fire regulations.

Smart is not a substitute for maintenance

The catch with any connected device is the assumption that it looks after itself. It doesn't. A smart alarm still needs testing, still collects dust in the sensor chamber, and still expires. Every smoke alarm in Australia, smart or not, must be replaced within 10 years of its manufacture date, because the sensor degrades whether or not the app still connects.

Our guide to smoke alarm maintenance covers the testing and cleaning schedule that keeps any alarm working.

If you want a smart alarm that meets Australian requirements rather than one that just looks the part, take a look at the Innohome Smart Smoke Alarm, or tell us what you're protecting and we'll point you to the right unit.

A smart smoke detector is a smoke alarm with connectivity. It can send an alert to your phone when you're away from home, interconnect with other alarms so they all sound together, and in some cases cut the power to the circuit causing the smoke. A standard alarm only sounds a siren.

Only if they carry AS 3786 certification. Many imported smart alarms sold online are not certified to the Australian standard, which means they don't satisfy legal requirements even if they work. Always check for the AS 3786 marking on the body of the unit before buying.

They're worth it if you're often away from home, manage a rental or aged care property, or want an alarm that acts rather than just alerts. An alarm that cuts power to a smouldering appliance stops the fire at its source. For a home that's always occupied, a compliant photoelectric alarm may be enough.

Yes. A smart alarm still needs monthly testing and six-monthly cleaning, and it must be replaced within 10 years of its manufacture date. The sensor degrades over time regardless of whether the app still works.
