Picked up a couple of these to replace our old system. Great product. Had a question on how best to set these up around our place and customer service was above and beyond - ask for Christian.

We purchased a pack of 5 photoelectric Smoke Alarms with free remote control online, after being quoted an exorbitant price to have the same alarms fitted by a local installer (more than double the cost of purchasing these alarms online myself)! I had checked out prices online and Photoelectric Smoke Alarms came in being very competitive and highly recommended in reviews. Ease of ordering was easy and delivery prompt. We ended up phoning Photoelectric Smoke Alarms as we were having difficulty pairing one of the alarms. Had the absolute pleasure of speaking with Christian, who could not have been more helpful! He talked us through the pairing and testing on our mobile phone. Christian made it so simple! He was courteous, friendly, professional, respectful and just terrific! We would highly recommend these inter-connected smoke alarms, especially with Christian being the "go to" help if needed! Thank you Christian!! (and Photoelectric Smoke Alarms!)

I highly recommend this business for their excellent advice, service and prompt dispatch of my smoke alarms.
It’s very rare these days to find good customer service and a good product but these guys do a great job. Christian was a pleasure to deal with and very knowledgeable of his products and was happy to call or respond to messages very quickly.

Amazing service and knowledgable, knows of what needs to be done to be compliant rather than being fearmongered into paying OTT prices. Thanks

Exceptional, professional and engaged with customer needs and problem solving. I placed two separate orders late one evening, realising I had to add an extra alarm for a 5-pack I had just purchased. I used the website "contact us" form in the hope of getting the orders consolidated into a single package, and also for the additional alarm to be synchronised / interconnected with the 5-pack. Christian called me first thing the next morning to confirm my requests, making sure I was happy with the solution he'd put in place. I had placed the orders and used the contact form at around 10pm Monday evening, received a call on Tuesday morning at 8:30am, and the package arrived today (Wednesday). We need more businesses like this.

I had ordered the wrong alarms, because 2 of my existing alarms were hard wired and couldn't legally be replaced with battery ones. I spoke to Christian on the phone for advice, and with no fuss, he refunded the ones I returned and sent the ones I needed. Excellent service.

Why Buy From Us?

Frequently Asked Questions

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

Warranty – Red smoke alarms come with a 10 year warranty. Premier Range alarms come with a 2 year warranty

Operating Range – Red smoke alarms have a slightly longer network reach (30m) than the Premier Range (25m).

Red smoke alarms also manufacture a 240v mains powered version of their alarm – this is useful for some people who require a combination of battery operated and 240v mains powered alarms to communicate with one another on the same network.

Our Red smoke alarms are not compatible with Premier Range smoke alarms, and vice versa (i.e. different brands cannot be interconnected together).

The Real Estate Institute of Queensland (REIQ) is Queensland’s peak body in real estate. Please refer to their website below.

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

No, we do not maintain a ‘bricks and mortar’ shopfront. Our listed address is an admin office only and we do not keep stock at this location. Maintaining a 100% online presence allows us to keep all overheads as low as possible – this is reflected in our smoke alarm pricing. Free shipping is also provided on all orders over $200.


All alarms in a bundle pack can be split up. For example, you may prefer to split a bundle pack of 10 alarms into two separate network groups by having 6 alarms in one property and 4 in another property (each network group functioning independently of the other). It’s entirely up to you to decide during the pairing process in your home, after you receive the alarms.

Refer to our pairing video for more information on how to wirelessly interconnect the alarms.

The number of smoke alarms required is relative to the size, floor layout and what state the dwelling is located in. QLD legislation 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 and depicts required smoke alarm locations within a building – use this as a guide for determining your own requirements.

Photoelectric Smoke Alarm Placement Recommendations

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

No, as our wireless alarms are battery operated (not hardwired to 240v mains power) they can be easily DIY installed 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.

This explains how to physically attach your smoke alarm to the ceiling.

One benefit from using wireless interconnected battery powered smoke alarms is that you can install them yourself without the need for an electrician or other tradesperson. Our smoke alarms come with complimentary anchor plus and screws to enable you to do it yourself – see below.

Note: Before installing any smoke alarms please review the ‘RECOMMENDED PLACEMENT’ section of our website for guidance.


STEP 1: Gently twist the mounting bracket to remove it from the rear of the smoke alarm.

STEP 2: Locate the mounting bracket in your chosen position on the ceiling. Use a pencil to mark the location of the two mounting bracket slots on the ceiling.

STEP 3: Using a 5mm drill bit, drill a pilot hole at each location marked on the ceiling. Insert the anchor plugs and use the two screws to attach the mounting bracket to the chosen position. Do not over-tighten the screws as this may distort the mounting bracket.

STEP 4: Attach the smoke alarm to the mounting bracket and turn clockwise to lock it into place. Test the smoke alarm by pressing the dual test / hush button.

Wireless interconnected smoke alarms work by communicating with each other using a radio frequency (RF) signal, without the need to physically install hard cabling between each alarm. 

When one alarm detects smoke, it will wirelessly ‘talk’ to all other alarms paired within the same network using the RF signal, so that all activate simultaneously (usually within 10 seconds of the initial detection). This provides a greater early warning and response time for occupants, especially in multi-story dwellings.

Our smoke alarms cannot be affected by other household RF devices (i.e. wireless smoke alarms situated in neighbouring properties) as the technology is purposely designed to eliminate any such interference during the unique network pairing process.

TV or A/C remote controls do not interfere with our alarms either as they typically use different technology (infrared IR vs radio frequency RF). The alarms do not use internet or home WiFi.

It is often impossible to tell if smoke alarms are interconnected just by looking at them with the naked eye. The best way to determine if your smoke alarms are interconnected is by testing them! Fortunately ours come with a dual test / hush button in the centre of the alarm itself to make this easy. 

Simply press and release the button to test your alarm – if all alarms within the same network activate then it means the alarms are successfully interconnected (note it may take up to 10 seconds for all alarms to activate – this is normal). You may also use the optional remote control device to test your alarms.

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

The Building Code of Australia also states that any new dwellings being built or dwellings being substantially renovated must have 240v hard wired photoelectric alarms installed.

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.
