Nano Range

Standalone Smoke Alarms

The Nano Range operates independently — no pairing, no panels, no network required. Each alarm detects and sounds on its own. Every Nano alarm is photoelectric, AS 3786:2014 compliant, and runs on a 10-year sealed battery. The full decade of protection with nothing to maintain.

Need Interconnected Alarms for a Queensland Property?

Queensland’s 2027 legislation requires interconnected photoelectric smoke alarms throughout the home — a requirement the standalone Nano Range does not meet on its own. If you are upgrading a Queensland property for compliance, the CAVIUS Wireless Family Range is the right choice. Our compliance guide walks you through exactly which alarms are required and where to install them.

CAVIUS vs Other Smoke Alarm Brands

Standard smoke alarms are typically 100mm or larger in diameter. The CAVIUS Nano changes what is possible — delivering compliant photoelectric detection in a 40mm housing that sits virtually flush to any ceiling. Here is how it compares.
Feature CAVIUS Nano Standard Standalone Alarm
Alarm diameter 40mm — world's smallest 100–150mm typical
Detection type Photoelectric (smoke) / Thermal (heat) Photoelectric or ionisation
Battery life 10-year sealed lithium 1-year replaceable
Battery replacement Unit replaced at 10 years Annual battery change required
AS 3786:2014 compliant Yes Varies by product
Design profile Flush to ceiling — barely visible Dome protrudes from ceiling
Nuisance alarm protection Dual mesh screening + humidity protection Basic mesh only
Units sold globally 3M+ N/A
A little genius

Smaller. Not Simpler.

Making a smoke alarm smaller usually means compromising the detection chamber. CAVIUS solved this with CORE Technology — a patented stacking design that places all components within a chamber sized for optimal photoelectric detection, not just for packaging. The result is not just a minimalist alarm. It is a more accurate one.
CORE Technology — What It Means for the Nano

CORE Technology is the engineering principle behind every CAVIUS alarm. It is the first design in the world to stack alarm components within an optimally sized photoelectric chamber — allowing a significantly smaller housing without reducing detection performance.

10-Year Sealed Battery

Both Nano alarms run on a sealed 10-year lithium battery. There are no user-replaceable batteries, no annual reminders, and no risk of the battery being removed and never replaced. When the 10-year life ends, you replace the alarm — exactly as Australian standards recommend.

Where to Use Nano Alarms

See the room-by-room placement guide below for bedrooms, kitchens, rentals, caravans, and design-led spaces.
Room / Space Recommended Product Why
Bedrooms & hallways 2008 CAV10 — Photoelectric Detects slow-burning smouldering fires most likely to occur at night
Kitchens & garages 3004 CAVTH10 — Heat alarm No nuisance alarms from cooking fumes, steam, or vehicle exhaust
Rental & investment properties 2008 CAV10 10-year sealed battery removes landlord maintenance obligation
Caravans & holiday homes 2008 CAV10 or 3004 CAVTH10 No hardwiring or network setup required
Heritage & design-led spaces 2008 CAV10 40mm profile — barely visible from across the room
Workshops & laundries 3004 CAVTH10 Heat detection handles dusty, steamy, high-humidity conditions

FAQs

A photoelectric smoke alarm detects smoke particles produced by burning materials — it is the recommended alarm for bedrooms, hallways, and living areas. A heat alarm detects a rapid rise in air temperature rather than smoke particles — it is the right choice for kitchens, garages, laundries, and other areas where cooking vapour, steam, or exhaust fumes would trigger nuisance activations in a smoke alarm.
Yes. Both the 2008 CAV10 and the 3004 CAVTH10 comply with AS 3786:2014, the Australian standard for residential smoke and heat alarms. They are suitable for use across all Australian states and territories.
No. Nano alarms are standalone devices and do not interconnect with the CAVIUS Wireless Family Range or any other alarm network. If you need all alarms to sound simultaneously — including for Queensland compliance — the Wireless Family Range is the right product.
No. Queensland legislation requires interconnected photoelectric alarms — meaning all alarms in the home must sound simultaneously when one triggers. The standalone Nano Range does not meet this requirement on its own. The CAVIUS Wireless Family Range is Queensland compliant.
Both Nano alarms have a 10-year service life. At the end of this period the alarm signals that it needs replacing. CAVIUS recommends replacing the entire unit — the sealed battery is not user-replaceable — and this approach is consistent with Australian standards guidance.
On the ceiling, as close to the centre of the room as possible. Avoid positioning within 300mm of a wall or corner, and keep away from cooking appliances, bathrooms, and air conditioning vents. Refer to your state fire service guidelines for full placement requirements specific to your state.
