These new QLD smoke alarm laws have been implemented due to several fires which have tragically resulted in multiple fatalities in each instance.

Coronial inquest findings noted that had each property been fitted with functioning interconnected photoelectric smoke alarms in prescribed locations, the occupants may have stood a better chance of survival.

Early smoke / fire detection improves escape time from a burning building. During a fire emergency, it was not only the heat and flames themselves which presented a life-threatening hazard, many victims were first overcome by an accumulation of smoke and toxic fumes.

Russell Island House Fire – Brisbane 2023

In the early morning of 6th August 2023, Emergency Services were called to a house fire on Russell Island, just off Brisbane’s southeast coast. The cause of the house fire remains undetermined, however it resulted in the loss of six lives – five young boys and their father who returned to the inferno in an attempt to rescue his children. The fire also destroyed two neighbouring homes and left several people needing treatment for burns and smoke inhalation.

The landlord and home owner was subsequently charged and fined for failing to install legally required and compliant smoke alarms in the Queensland rental property.

Slacks Creek House Fire – Brisbane 2011

Just before midnight on 23rd August 2011, an accidental fire ripped through a house in Slacks Creek, South Brisbane.

The fire was to cause the greatest loss of life in a domestic house fire in Australian history, with a total of 11 people (including many children) perishing due to smoke inhalation.

A finding from the 2014 Coronial Inquest stated that;
‘Once this particular fire started, it is likely that some or all of the deaths would have been prevented if the sleeping occupants had been quickly awoken and had realised that they needed to leave the house as quickly as possible … smoke alarms were either not present in the dwelling or were not maintained’.

Many recommendations from the Coronial Inquest were incorporated into the QLD Building Fire Safety (Domestic Smoke Alarms) Legislation Amendment Regulation 2016.

The legislation itself may be viewed at the Queensland Government website below;

Palace Backpackers Fire – Childers 2000

On 23rd June 2000 at 1am a disgruntled resident deliberately lit a fire inside the Palace Backpackers Hostel in Childers, southeast Queensland.

The fire spread rapidly throughout the old timber building and the hostel did not have working smoke detectors or alarms. The result? 15 young people sadly lost their lives. The arsonist was captured by police and sentenced to life in prison. The devastating effect of this event is still evident on the local township to this day.

Queensland has the most stringent smoke alarm laws in the nation. These laws have been amended and updated over time due to several tragic fires which have resulted in significant loss of life.

Queensland smoke alarm legislation

The two main pieces of legislation in Queensland are the;

  • Fire and Emergency Services Act 1990
  • Building Fire Safety Regulation 2008

The objectives of the legislation are to ensure that all fire safety installations (including smoke alarms) within a building are maintained, and to ensure that people can safely evacuate from a building in the event of a fire.

Building Fire Safety Regulation 2008 – smoke alarms

Part 5A of the QLD Building Fire Safety Regulation 2008 deals specifically with smoke alarm requirements for domestic dwellings. It states that smoke alarms must;

  • Comply with the Australian Standard (AS 3786:2014).
  • Contain a photoelectric sensor, and not also contain an ionization sensor.
  • Be either hardwired into the building’s main power supply or powered by a non-removable minimum 10-year lifespan battery.

Where should smoke alarms be installed?

Part 5A also states exactly where smoke alarms must be installed inside a domestic dwelling (prescribed locations). It says that photoelectric smoke alarms must be installed in;

  • each bedroom.
  • the hallway which connects each bedroom.
  • if there is no hallway connecting each bedroom, then a part of the storey that is between the
    bedroom and the rest of the dwelling.
  • for each storey with no bedrooms—on the most likely travel path of exit from the dwelling.

Where should smoke alarms not be installed

Part 5A (3) also provides exact distances and measurements where smoke alarms should / should not be installed. It states that smoke alarms must not be installed;

  • within 300mm of a light fitting.
  • within 300mm of a corner of the ceiling and a wall.
  • within 400mm of an opening from which air is supplied from an air conditioner or forced air vent.
  • within 400mm of the blades of a ceiling fan.

Fire and Emergency Services Act 1990 – smoke alarms

In addition to the above, Division 5A of the QLD Fire and Emergency Services Act 1990 stipulates that from 1st January 2022 all rental properties and properties being sold in Queensland must have smoke alarms which;

  • Are less than 10 years old.
  • Operate when tested.
  • Be interconnected with every other smoke alarm in the building so that all activate together.

If the smoke alarm being replaced was hardwired to the domestic dwelling’s electricity supply, the replacement smoke alarm must also be hardwired to the dwelling’s electricity supply. Any newly constructed homes or substantial renovations must have interconnected photoelectric smoke alarms which are hardwired to the mains power supply. A definition of a ‘substantial renovation’ is provided within the Act.

Furthermore, these smoke alarm requirements will become mandatory for ALL dwellings in Queensland by 1st January 2027.

Smoke alarms in QLD rental properties

With respect to QLD rental properties, the Act also states that;

  • The lessor must test each smoke alarm within 30 days before the start of a tenancy in a domestic dwelling.
  • The tenant must test each smoke alarm in the dwelling at least once every 12 months.
  • If the tenant is aware a smoke alarm in the dwelling has failed, the tenant must advise the lessor as soon as practicable.
  • The tenant must clean each smoke alarm at least once every 12 months.

Before buying a smoke alarm 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). The first of this two part series will review Australian Standard 3786:2014 to assist your purchasing decision.

Australian Standard 3786:2014

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.

Australian Standard 3786:2014 is divided into several key components – the two of interest that will be reviewed in this article are ‘tests’ and ‘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, etc.

Smoke alarm photoelectric chamber – insect screen

How does this requirement translate into the design and manufacture of your photoelectric smoke alarm? The image below shows the compliant internal component from a ZEN wireless interconnected photoelectric smoke alarm. The polymer mesh screen 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 most 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 must be no larger than 1.3mm diameter

In addition to this internal mesh screen around the perimeter of the photoelectric chamber, the wireless interconnected photoelectric smoke alarm also has an outer grill which forms part of the housing of the smoke alarm. The external grill also prevents larger foreign bodies from entering the alarm itself. Foreign bodies (i.e., insects) are a common cause of false / nuisance alarms because they can enter the sensitive internal components and disrupt the photoelectric light beam.

We hope you have enjoyed this review of Australian Standard 3786:2014 and how it translates to the design of your smoke alarm. Whilst many smoke alarm retailers might profess to be aware of the standard, very few can claim to have read it from cover to cover or have a genuine understanding of what it really means.

Nothing is more frustrating than a smoke alarm going off for no reason (especially at 2am in the morning!). But why is your smoke alarm beeping when there is no smoke? There can be several causes of nuisance alarms. The good news is that you don’t have to go on living this way – our ZEN wireless interconnected photoelectric smoke alarms provide reliable protection for you and your family!

The basic operating principal of an interconnected photoelectric smoke alarm is that it activates when the light beam inside the smoke alarm chamber is broken or disrupted – typically by tiny smoke particles. However these foreign particles can come from sources other than real smoke too – below are some of the most common examples and how to resolve them.

High humidity affecting your smoke alarms

High humidity may occur naturally as the air carries dense moisture particles that your smoke alarm confuses for smoke particles. Although brands can differ, smoke alarms should be designed to work up to 93% relative humidity – anything over this range and the air could become dense enough to scatter the light beam of a photelectric sensor. Extreme tropical weather conditions in far north Queensland and the Northern Territory can sometimes produce high humidity above 85% which may begin to affect an alarm.

High humidity may also be created artificially due to steam vapour from a bathroom shower, or a clothes dryer operating in a laundry room for example. If your smoke alarm is positioned outside a bathroom entrance or in a laundry consider moving it further away or relocating it completely so that escaping shower steam and dense air vapour doesn’t trigger nuisance alarms and start the smoke alarm beeping unnecessarily.

Insects inside your smoke alarm

Section 4.17 of Australian Standard 3786:2014 requires all smoke alarms to have protection against foreign bodies, so that a sphere of diameter larger than 1.3mm cannot pass into the sensor chamber – this protection is provided by way of an internal mesh screen. Despite this requirement it is still possible that very tiny insects (smaller than 1.3mm) could enter the smoke alarm and by doing so interfere with the photoelectric sensor. One tip to reduce this likelihood is to wipe the ceiling perimeter around your smoke alarm with surface insect spray (being very careful not to allow the insect spray itself to touch the alarm as this may affect the internal sensors).

Dust inside your photoelectric smoke alarm

A build-up of dust in the air may also affect your smoke alarm. If dust particles enter the internal chamber they will interfere with the photoelectric light beam and trigger nuisance alarms. We recommend cleaning your smoke alarms regularly by gently vacuuming around them with a soft brush attachment from your vacuum cleaner. Cleaning your smoke alarms in this way may remove any cobwebs which could also prevent pests from entering the alarm. Be cognisant of any activities in the home which may create excess dust – for example renovations, or shaking out old dusty blankets or doonas in a room which has a smoke alarm installed.

Cooking smoke affecting your smoke alarm sensors

It is true that whilst many house fires start in the kitchen, installing an alarm in the kitchen may also elicit many nuisance alarms and start the smoke alarm beeping unnecessarily. It doesn’t matter what brand of smoke detector you have, if you install it too close to the kitchen stovetop or oven it will activate when smoke particles are emitted from the cooking food (after all, the smoke alarm is just doing what it is designed to do). When cooking, be sure to use the oven exhaust fan or rangehood to draw smoky air particles away from the vicinity of your smoke alarm. If the problem persists, consider repositioning the alarm further away from the cooking appliance.

Conclusion

Beeping smoke alarms without an obvious apparent reason can be both frustrating and stressful. Worse, repeated false alarms may induce a ‘boy who cried wolf’ syndrome and reduce home occupants reaction to a real life fire event.

Fortunately, our ZEN wireless interconnected photoelectric smoke alarms undergo strict quality control measures and are manufactured at an ISO 9001 quality accredited facility, in adherence to Australian Standard 3786:2014, and are independently tested and verified which help reduce the likelihood of nuisance smoke alarms. Using the tips outlined above and below, your smoke alarms will provide many years of stress free and reliable fire protection.
