Product Overview
The 2012/24AUSI is a 4-wire photoelectric smoke alarm with a built-in Temp-3 sounder, designed to interconnect directly into a security, fire, or access control panel's alarm circuit. Unlike a standalone battery smoke alarm, it runs on 9–30VDC from the panel itself, with a 9V battery included as backup, and reports through NO/NC relay contacts an installer can wire straight into a monitored system.
Photoelectric detection suits open-area protection where slow, smouldering fires are more likely than fast flaming ones, and the integral Temp-3 sounder delivers an 85dBA evacuation tone that meets the ISO8201 standard. Certified to AS3786:2014, it's built for installers who need a code-compliant, interconnectable smoke alarm rather than a plug-and-play domestic unit. Supplied directly through Total Security Equipment.
Key Capabilities
4-Wire Panel Integration
Runs on 9–30VDC from a security, fire, or access control panel — no separate power supply needed.
Integral Temp-3 Sounder
Built-in 85dBA @ 3m evacuation sounder compliant with the ISO8201 standard tone.
Interconnects Up to 24 Alarms
Link up to 24 units so any one alarm triggers evacuation sounders across the whole run.
NO/NC Relay Contacts
Changeover relay contacts report alarm status directly into a monitored panel zone.
8-Second Alarm Verification
Reduces false alarms by verifying smoke is still present before triggering.
AS3786:2014 Certified
Meets the current Australian standard for smoke alarms.
What's Included
Best For
Wires directly into a security or access control panel's alarm circuit.
Link up to 24 alarms so every sounder triggers together, wherever smoke is detected.
Photoelectric sensing suits hallways, offices, and open living areas.
AS3786:2014 certification for installers who need a compliant, documented alarm.
Why Choose the 2012/24AUSI
A standalone battery smoke alarm can't report into a monitored panel or trigger other connected devices. This 4-wire model is built specifically for that job — it draws power from the panel circuit, reports alarm status through relay contacts, and interconnects with up to 23 other units on the same run, all while meeting the same AS3786:2014 certification as a standalone alarm. Available from Total Security Equipment.

Choosing the Right Alarm
Choose the 2012/24AUSI if…
- You need a smoke alarm that reports into a security or access control panel.
- You want multiple alarms interconnected so they all sound together.
- You need AS3786:2014 certification for a compliant install.
Choose a different alarm if…
- You need a standalone battery-powered alarm. This model requires a 4-wire panel connection, not just a battery.
- Your site needs ionisation-type detection. Ask our team about alternative detector types for fast-flaming fire risks.
- You don't have a compatible panel or 9–30VDC circuit. Ask our team what else you'd need to install this alarm.
FAQs
1. Does this smoke alarm work on its own, or does it need to be wired in?
It needs a 4-wire connection to a compatible panel or 9–30VDC power source. The included 9V battery is backup only, not the primary power supply.
2. How many of these alarms can I interconnect together?
Up to 24 units can be interconnected, so an alarm triggered by one unit sounds across the whole run.
3. Is this alarm certified for use in Australia?
Yes — it's CSIRO Activfire listed and certified to the AS3786:2014 Australian smoke alarm standard.
4. How loud is the built-in sounder?
The integral Temp-3 sounder produces 85dBA at 3 metres, meeting the ISO8201 evacuation tone standard.
5. Where can I buy the 2012/24AUSI smoke alarm in Australia?
It's available directly from Total Security Equipment.
