When it comes to protecting your home and family, choosing the right smoke alarm is key. Not all smoke alarms are created equal, and making the right choice could mean the difference between life and death in a fire emergency. One of the most effective solutions on the market today are interconnected smoke detectors, particularly those with photoelectric technology. These alarms detect slow, smouldering fires—the type most common in home fires—faster and with greater accuracy than older ionisation alarms.

But why is this type of smoke detector so important, and how can correct Australian Standard Certification (the red ‘5-ticks’ logo) give you the confidence you need in your purchase? Understanding the difference between certified and non-certified interconnected smoke detectors ensures you invest in a product that meets Queensland’s strict safety laws and provides maximum protection for your loved ones. Read on to find out!

What Are Interconnected Smoke Detectors?

Interconnected smoke detectors are designed to link multiple alarms throughout your home. When one alarm detects smoke, it automatically triggers all the alarms in the network using a radio frequency (RF) signal. This means that whether you’re asleep in the bedroom upstairs or watching TV in the living room downstairs, you’ll be alerted to danger, no matter where the fire starts. For families with large homes or multi-level houses (or with teenagers with headphones on), having interconnected smoke detectors offers an added layer of protection, ensuring no part of the home is left vulnerable.

Why Photoelectric Smoke Detector Technology Matters

Photoelectric smoke detectors are renowned for their ability to detect slow, smouldering fires—common in home settings. These fires often produce significant amounts of smoke before erupting into visible flames, making early detection critical – once active flame state is achieved, a fire can engulf a modern home in a matter of minutes. Unlike older ionisation alarms, photoelectric models are highly sensitive to smoke from smouldering materials such as furniture or electrical wiring.

Australian Standard Red ‘5-Ticks’ Certification

Beware – not all interconnected smoke detectors are created equal. Did you know that smoke alarm manufacturers have a choice of certification agencies to certify their smoke detector? Some certification agencies such as Intertek SAI Global are well known and established – you will see their red Australian Standard logo (commonly known as the ‘StandardsMark’ or red ‘5-ticks logo’) not only on smoke alarms, but on a variety of Australian certified products.

This certification is assurance that your interconnected smoke detectors have been rigorously assessed to meet Australian Standard AS 3786:2014. As part of the assurance process, Intertek SAI Global send an independent audit team to the smoke detector manufacturing facility every year to inspect and verify the manufacturing and testing process. A report is produced and any non-conformances are immediately identified and rectified – this ongoing process ensures safety and quality standards are maintained indefinitely.

ZEN interconnected smoke detectors and the red 5-ticks logo for Australian Standard certification

How do you know if the smoke alarm manufacturer is genuine and legally authorised to use the red logo above? Simple – look them up! You can see the license number above ‘SMK41401’. This license number is unique to the manufacturer’s certificate and can be searched on the Intertek SAI Global database. Check it out here. The database applies not only to interconnected smoke detectors, but to any Australian Standard Certified product!

However, another choice for smoke detector manufacturers is to certify their product using an offshore certification agency, which is cheaper but far less reputable. While this might seem like a cost-saving measure, it comes with significant risks. Surprisingly, the Australian Standard verification process for these budget certification agencies does not require visiting or auditing the manufacturing facility at all! Instead, these agencies rely solely on a once-only desktop review of paperwork, such as a smoke detector test report, and then approve the product as Australian Standard certified based on these documents alone—without ever physically inspecting the product or factory.

This raises serious concerns about the reliability and safety of smoke alarms certified under these methods. Without stringent on-site audits, there is no guarantee that ongoing production maintains the same quality as the initial sample tested. Manufacturers may cut corners after certification, leading to inconsistent performance and, ultimately, a device that fails when it’s needed most.

Note that while these cheaper certification agencies may claim their product meets Australian Standards and even produce their own ‘certificate’ to attest to this, they do not have permission to use the official Australian Standard red ‘5-ticks logo’ that consumers recognize as a mark of genuine quality and trust. Always look for the Australian Standard red ‘5-ticks logo’—this is your assurance that the smoke alarm has been rigorously tested and certified under strict regulatory oversight.

By choosing interconnected smoke detectors that display the official Australian Standard red ‘5-ticks logo’, like those from ZEN Smoke Alarms, you are investing in a product that has been tested for quality, reliability, durability, and long-term performance. These alarms undergo thorough assessments year after year, ensuring they provide the highest level of fire protection for your home and family. Cutting corners on safety isn’t worth the risk—choose verified, high-quality alarms that meet Queensland’s strict smoke alarm regulations.

If you currently have smoke alarms compliant with Australian Standard 3786:2014, there is no immediate requirement to replace them simply because AS 3786:2023 has been released. A new Australian Standard for smoke alarms does not automatically impose a legal obligation for homeowners to upgrade their alarms—compliance with any standard only becomes mandatory when it is formally referenced in government legislation or building codes.

At the time of writing, Queensland fire safety laws and the National Construction Code (NCC) 2022 still reference Australian Standard 3786:2014. This means that existing smoke alarm installations compliant with AS 3786:2014 remain legally valid.

However, it’s still essential to regularly check your smoke alarms to ensure they are in working condition. If a smoke alarm is non-functional, damaged, or older than 10 years from the manufacture date, it must be replaced. Photoelectric interconnected smoke alarms are always recommended for optimal fire detection and safety, as they provide early warning and faster response times in case of fire.

Upgrading to the latest wireless interconnected smoke alarms can significantly enhance household protection and convenience, ensuring that every alarm in your home activates simultaneously in an emergency.

Interconnected Smoke Detectors

And Australian Standard 3786:2014

Before buying interconnected smoke detectors you should do your due diligence to ensure it is compliant to Australian Standard 3786:2014. The full name of the standard which encompasses smoke alarms in Australia is ‘Australian Standard 3786:2014 Smoke alarms using scattered light, transmitted light or ionization’ (incorporating amendment 1 and 2). This article will review Australian Standard 3786:2014 to assist your purchasing decision.

Standards are documents that set out specifications, procedures and guidelines to ensure products are safe, consistent, and reliable. Australian Standard 3786:2014 is referenced by QLD’s Building Fire Safety Regulations 2008 – when a standard is referenced by state or national legislation, compliance with it becomes mandatory. It is interesting to note that although there is a newer Australian Standard 3786:2023 – it is not yet referenced by legislation – therefore Australian Standard 3786:2014 must still be complied with in the eyes of the law.

Interconnected smoke detectors and Australian Standard 3786:2023

Interconnected smoke detectors and Australian Standard 3786:2014

Australian Standard 3786:2014 is divided into several key components – the area of interest that will be reviewed today is section 4.17 – ‘general requirements’.

Section 4.17 of the Australian Standard states that; ‘The smoke alarm shall be so designed that a sphere of diameter larger than 1.3 ±0.05 mm cannot pass into the sensor chamber(s)’. This requirement is intended to restrict the access of foreign bodies such as insects into the sensitive parts of the smoke alarm (to prevent nuisance alarms).

It is known that this requirement is not sufficient to prevent the access of all insects; however, it is considered that extreme restrictions on the size of the access holes may introduce the danger of clogging by dust, which could compromise the alarm’s functionality. Therefore, manufacturers must strike a balance between preventing false alarms caused by insects and ensuring the smoke alarm remains effective by allowing airflow for proper smoke detection. This balance is key for maintaining the reliability and performance of interconnected smoke detectors in real-world conditions.

Interconnected Smoke Detectors – Mesh Screen

How does this requirement translate into the design and manufacture of photoelectric interconnected smoke detectors? The image below shows the compliant internal component from one of our ZEN wireless interconnected smoke detectors. The polymer mesh surrounding the sensitive photoelectric chamber within the alarm contains thousands of tiny holes, each perfectly engineered, no larger than 1.3mm in diameter. The tiny holes prevent insects from accessing the internal chamber whilst still allowing air (and smoke) to pass through.

Mesh screen surrounding the photoelectric smoke alarm internal sensor chamber

As per Australian Standard 3786:2014 – holes are no larger than 1.3mm diameter

In addition to this internal mesh screen around the perimeter of the photoelectric chamber, ZEN wireless photoelectric interconnected smoke detectors also have an external housing that forms part of the smoke alarm itself. This external housing acts as a crucial barrier, preventing larger foreign bodies from entering the alarm. Foreign bodies such as insects and small house geckos are a leading cause of false alarms, as they can interfere with the sensitive photoelectric light beam, triggering unnecessary alerts.

By incorporating both an internal mesh screen and an external housing, ZEN Smoke Alarms are designed to minimize false alarms while maintaining optimal smoke detection performance. This level of attention to detail reflects our commitment to quality and compliance with Australian Standard 3786:2014.

Many retailers may claim their smoke alarms meet the standard, but few have truly studied it in depth. At ZEN Smoke Alarms, we don’t just sell interconnected smoke detectors—we are industry experts who ensure every product is rigorously tested and fully compliant. Choose ZEN for reliable, high-quality protection you can trust.

Australian Standard 3786:2014 – Smoke Alarms Using

Scattered Light, Transmitted Light or Ionization

All photoelectric interconnected fire alarms sold within Australia must comply with Australian Standard 3786:2014.

Section 4.22.1 of the Australian Standard describes the markings and types of information that must be included on the interconnected fire alarm itself. This ensures consumers can verify compliance and make informed purchasing decisions. If the interconnected fire alarm does not have all this required information on it—such as model number, manufacturing details, and compliance markings—then technically, it is non-compliant with the standard. Purchasing non-compliant smoke alarms can lead to safety risks, legal issues, and potential insurance claim complications in the event of a fire. Always choose Australian Standard certified alarms for peace of mind and total protection.

Required Information To Be Printed

On An Interconnected Fire Alarm

Have a look at the photoelectric interconnected fire alarm on your ceiling to double check if it has the following information.

4.22 Markings

4.22.1 Smoke alarm

Each smoke alarm shall be legibly and indelibly marked with the following:

(a) The number and date of this Standard (i.e. AS 3786:2014).

(b) The name or trademark and address of the manufacturer or supplier.

(c) The model designation (type or number).

(d) The type of smoke alarm (type A or type B), e.g. photoelectric or ionization.

(e) The alarm condition aural signal pattern (ISO 8201 or ISO 7731).

(f) The date of manufacture which may be coded into a serial number or the batch

number.

(g) The recommended date for replacement, subject to normal, regular maintenance

Interconnected Fire Alarm ‘DO NOT PAINT’ Marking

Additionally, a notice on the outer surface of the enclosure marked ‘DO NOT PAINT’ is required. The letters shall be not less than 3 mm high and must remain plainly visible after the smoke alarm is installed in its intended manner. This warning is critical, as painting over a smoke alarm can interfere with its functionality and compromise its ability to detect smoke effectively.

Be wary of many cheap ‘knock-off’ smoke alarms sold in online marketplaces—they often lack essential compliance markings, even though they claim to meet Australian Standard 3786:2014. Without these markings, there is no guarantee that the alarm has been properly tested or certified, putting your home and family at risk.

Whilst it may seem trivial whether the interconnected fire alarm has this information on it or not, in the event of a house fire and subsequent insurance claim, your insurer could be double-checking this same information before approving any pay-out. Investing in fully compliant, high-quality smoke alarms—like those from ZEN Smoke Alarms—ensures both safety and peace of mind.
