I needed an extra smoke detector at short notice which was compatible with what I had ordered 6 months previously. I rang and spoke to Christian who looked up exactly what detector I needed and express posted it to me immediately to ensure I received it the next day. He even rang me back to tell me when it was on the way. This level of customer service is very rare. Would definitely recommend to anyone else. Lloyd

I purchased a package of smoke detectors a few years ago and now realise I need a couple more. I contacted Christian who couldn't have been more helpful, even offering an over the phone assistance to pair the two new detectors to my original ones. Items are already on their way!! Great service and can't thank you enough.

Frequently Asked Questions

Yes! Whilst our ZEN bundle packs will arrive to you pre-interconnected as one group – all alarms in a bundle pack can be split up. For example, you may want to split a 10 pack bundle into two separate groups by having 6 alarms in one property and 4 alarms in another property (with each group functioning independently of the other). You can even purchase extra individual alarms to add into a bundle pack group and make it bigger. It’s entirely flexible and up to you to decide.

Refer to our setup & install page for more information. 

No, we do not have a traditional ‘bricks and mortar’ shopfront. Our listed address is an administration office only and we do not keep stock at this location. Maintaining a 100% online presence allows us to keep overheads as low as possible – this is reflected in our smoke alarm pricing. 

If you require smoke alarms urgently and/or time critical please let us know prior to placing your order and we can send it express post at no extra cost!

The number of smoke alarms required is relative to the size, floor layout and what state the dwelling is located in. QLD law states that a smoke alarm must be installed;

  • on each storey
  • in each bedroom
  • in hallways that connect bedrooms and the rest of the dwelling
  • if there is no hallway, between the bedroom and other parts of the storey
  • if there are no bedrooms on a storey, at least one smoke alarm must be installed in the most likely path of travel to exit the dwelling.

The example floorplan below was developed by the Queensland Fire and Emergency Services (QFES) and depicts required smoke alarm locations within a dwelling – use this as a guide for determining your own requirements.

Wireless Interconnected Photoelectric Smoke Alarm Placement Recommendations

The ‘recommended placement’ section of our website also contains more information.


No, as our ZEN wireless interconnected smoke alarms have a non-removeable 10-year battery (not hardwired to 240V mains power) they can be easily installed by yourself and do not require an electrician.

Please note however if you purchase one of our Red 240V hardwired smoke alarms then yes it will need to be installed by a licensed electrician.

No. The interconnection is wireless and uses a radio frequency so that the alarms must be uniquely paired to one another. All alarms in one property are paired with a ‘master’ alarm, which is distinct from a ‘master’ alarm on any adjoining property.

Please refer to the Real Estate Institute of Queensland’s (REIQ) fact sheet below.

Our blog post also contains more information about smoke alarm compliance when selling your property in QLD.

Selling in QLD and the smoke alarm compliance certificate

Legislation states that if an existing 240v hardwired alarm is to be replaced, then it must be replaced with a 240v hardwired photoelectric smoke alarm.

The National Construction Code (NCC) also states that any new dwellings being constructed or being substantially renovated must have 240v hardwired photoelectric smoke alarms installed.

Both brands comply to Australian Standard 3786:2014 and both brands are very good!

Emerald Planet smoke alarms also manufacture a 240V hardwired (mains powered) smoke alarm – this is useful for some people who require a combination of both types in their property (QLD legislation says any existing hardwired smoke alarms must be replaced with hardwired).

Emerald Planet smoke alarms are not compatible with ZEN smoke alarms, and vice versa (i.e. different brands cannot be interconnected together).

Some insurance providers can decline to quote your property if you don’t fulfil their underwriting criteria when it comes to fire protection. It is always recommended to install interconnected photoelectric smoke alarms and check with your insurance provider or insurance broker to make sure you meet the necessary requirements.
