Interconnected smoke alarms are a critical safety feature in any home, designed to alert occupants to the presence of smoke or fire, providing valuable time to evacuate. ZEN Interconnected smoke alarms, in particular, offer an enhanced level of safety by ensuring that when one fire alarm detects smoke, all interconnected smoke alarms in the group sound off. A key component that ensures interconnected smoke alarms function reliably is the internal lithium battery.

Why Lithium Batteries In Interconnected Smoke Alarms?

Lithium batteries are increasingly used in interconnected smoke alarms due to numerous advantages over traditional alkaline batteries. Conventional 9v alkaline smoke alarm batteries deplete rapidly and have to be replaced every year. The depleted alkaline battery causes the smoke alarm to emit what is known as the infamous low battery ‘chirp’. In an effort to silence the repetitive and annoying low battery chirp people removed the 9v smoke alarm battery, forgetting to replace it with a new one, often with disastrous consequences – smoke alarms can only detect smoke if they have power.

Lithium batteries have a significantly longer lifespan, designed to last for 10 years, which aligns with the recommended replacement interval for interconnected smoke alarms themselves. This longevity reduces the need for frequent battery changes, minimizing the risk of having interconnected smoke alarms with a dead battery (or no battery), which could be life-threatening in a fire emergency.

Battery Reliability And Performance

Lithium batteries inside interconnected smoke alarms are also known for their stable voltage output. Unlike 9V alkaline batteries, which tend to lose power gradually, 3V lithium batteries maintain a consistent voltage until they are almost depleted. This stability is crucial in interconnected smoke alarms, where consistent power is needed to ensure reliable operation. Additionally, lithium batteries perform well in a wide range of temperatures, making them ideal for use in various parts of the home across different states and regions of Australia. The 10-year long life batteries sealed inside ZEN interconnected smoke alarms are non-removeable and non-replaceable. After 10 years the fire alarms (including the batteries sealed inside them) are simply swapped out for new fire alarms.

Are The Lithium Batteries Inside My

Interconnected Smoke Alarms A Fire Hazard?

No they aren’t. There are several reasons why we don’t hear news stories of lithium batteries spontaneously combusting inside interconnected smoke alarms. The 10-year long life lithium batteries in interconnected smoke alarms differ in design from lithium-ion batteries used in e-scooters, e-bikes etc. – it is these mobility devices which have seen a massive surge in the frequency of lithium battery fires as reported in the media. Interconnected smoke alarms contain two small 3V, single-use, lithium batteries sealed within the fire alarm itself. These batteries are non-replaceable and are designed to deplete slowly and steadily over a 10-year lifespan. At the end of this period, the interconnected smoke alarms are disposed of in their entirety (including the batteries sealed inside), and new interconnected smoke alarms are installed in-situ. The same fire and thermal runaway risks associated with continuous and repeated recharging of large, high energy lithium-ion batteries used in e-bikes, e-scooters and other mobility devices are not present with the two small non-rechargeable lithium batteries inside interconnected smoke alarms.

Furthermore, large high energy lithium batteries used in mobility transportation devices are often physically damaged due to bumps or knocks (riding an e-bike or e-scooter over the curbside or on an uneven concrete footpath etc.) which may contribute to thermal battery runway and pose a significant overheating / fire hazard. The same risk exposure for causing lithium battery damage is not present with interconnected smoke alarms attached to a ceiling – once installed they do not move or get subjected to damaging dynamic forces.

Safety Benefits of Interconnected Smoke Alarms

Interconnected smoke alarms provide a network of protection throughout the home. If one alarm detects smoke or fire, all connected alarms will sound, alerting occupants even if they are in a different part of the house. This is particularly important in larger homes or homes with multiple levels, where a fire might go unnoticed if alarms were not interconnected. The lithium battery’s long life and reliability enhance this system, ensuring that all the interconnected smoke alarms are functional and ready to alert occupants in case of an emergency.

When purchasing interconnected smoke alarms, it is essential to choose fire alarms that comply with Australian Standard 3786:2014, as indicated by the official Australian Standard red ‘5-tick’s mark on the packaging and the product itself. Product testing required of this standard helps ensure that the smoke alarm poses no electrical danger during normal use. Additionally, interconnected smoke alarms should carry the electrical Regulatory Compliance Mark (RCM), affirming compliance with Australian electrical safety regulations outlined in Australian Standard 3820:2020. Avoiding cheap imported knock-offs without the RCM mark is crucial for battery safety – have a look at the rear of your interconnected smoke alarms today – do they have the Regulatory Compliance Mark?

Battery Environmental Considerations

The lithium batteries inside interconnected smoke alarms are also more environmentally friendly compared to their alkaline counterparts. Fewer replacements mean less waste, which is a positive step towards reducing the environmental impact. Additionally, many lithium batteries are recyclable, which further minimizes their footprint. Lithium-ion batteries are a source of many valuable materials. If recycled, potentially 95% of battery components can be recovered for alternative use or may even be turned into new batteries. B-cycle is Australia’s national battery recycling scheme, supporting a collection network for used batteries.

Interconnected Smoke Alarms Battery – Conclusion

The lithium battery in interconnected smoke detectors plays a key role in modern home safety. Its long life, safe and reliable performance, and environmental benefits make it an ideal choice for ensuring that ZEN interconnected smoke alarms are always ready to protect. As technology continues to advance, we can expect further improvements in battery technology, making our homes even safer. Regularly testing your interconnected smoke alarms and replacing them every 10 years, as recommended, ensures that these devices will continue to provide reliable service, powered by the longevity and consistency of secure lithium batteries.

These devices have revolutionized fire safety, providing protection that’s not just smarter, but also faster and more reliable. Whether you’re a homeowner, a landlord, or just someone who values safety, understanding the benefits of interconnected smoke alarms is vital, especially in the state of Queensland with new legislation mandating interconnected smoke alarms in ALL dwellings by 2027.

Don’t forget to read the interconnected smoke alarms FAQ list at the conclusion of this article – we provide answers to the most common interconnected fire alarm questions!

Why Do Interconnected Smoke Alarms Matter?


Imagine a fire starting in a remote part of your home, like the garage or a downstairs laundry, whilst you are fast asleep upstairs in the second floor bedroom. Speed is everything in a fire emergency – a fire can double in size every 30 seconds, so every second counts. Without interconnected smoke alarms, you might not hear the alert until the fire has spread significantly. Interconnected smoke detectors are linked so that when one detects smoke, they all sound the alarm simultaneously – you’re not relying on just one device to protect your entire household. This interconnected fire alarm system ensures that no matter where the fire starts, everyone is alerted immediately – it provides occupants with a crucial time advantage to either escape or respond to the fire situation.

Interconnected Smoke Alarms –

A Legal And Sensible Choice


Interconnected smoke alarms are strongly recommended by every state fire department within Australia. Queensland, however, is the first state to make interconnected smoke alarms not only a ‘recommendation’ – but a compulsory legal requirement for ALL home types and situations. Queensland’s strict new fire safety laws make it mandatory for all homes to have interconnected smoke alarms by 2027, but this isn’t just a legal hoop to jump through – it’s about ensuring the best possible protection for your family. The early detection and widespread alert provided by interconnected fire alarm systems have been proven to save lives, particularly in multi-level homes or properties with hard-to-hear areas like granny flats or detached garages.

Interconnected Smoke Alarms Are

So, if you haven’t already made the switch, now is the time. It’s not just about compliance—it’s about making sure your home is as safe as it can be.

Interconnected Smoke Alarms Frequently Asked Questions

Below are answers to some of the most commonly asked interconnected fire alarm questions. Read on!

Do interconnected smoke alarms need to be hardwired?

No they don’t. ‘Hardwired’ refers to how a smoke alarm receives its power and not the method for interconnecting the smoke alarm (i.e. 240V hardwired vs 10 year battery powered). Australia’s National Construction Code and state legislation do not prescribe how a smoke alarm must be ‘interconnected’.

Do interconnected smoke alarms require wifi or internet to function?

ZEN Smoke Alarms have a radio frequency (RF) transmitter inbuilt into each alarm – that is how our interconnected smoke alarms communicate with one another – no internet or home wifi required!

What is the range / distance of interconnected smoke alarms?

ZEN interconnected smoke alarms can operate in a 100m free-field range provided the alarms are not greater than 30m apart from one another. This is a huge distance and more than ample coverage for the average Australian home.

I have a multi-storey house with solid concrete walls and ceilings –

will the interconnected smoke alarms still work?

This is not an issue with ZEN interconnected smoke alarms (we can’t speak for other brands though). Our interconnected smoke alarms are designed to function throughout large size multi-storey properties – upstairs, downstairs, inside and throughout the entire building with solid concrete walls, ceilings, floors etc. it is not a problem.

Can interconnected smoke alarms be triggered in neighbouring properties?

No, it is not possible to accidentally activate or trigger the interconnected smoke alarms in your neighbours house (and vice versa) – imagine the chaos occurring right around Australia if this were the case! All alarms in one group are paired with a ‘master’ alarm, which is distinct from a ‘master’ alarm in any other group.

Will interconnected smoke alarms be affected by other appliances?

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).

Can I split up a ZEN Smoke Alarm bundle pack and use in separate properties?

Yes, absolutely! Whilst ZEN bundle packs arrive to you already pre-interconnected as one group, alarms in a bundle pack can still be split up. For example, you may prefer to split a 10-pack smoke alarm bundle into two separate groups by having 5 alarms in one property and 5 in another property (each group functioning independently of the other). You can even purchase extra ZEN alarms to add into a bundle pack group and make it bigger. It’s fully flexible and up to you to decide. Configuring a new interconnected fire alarm group takes less than 2 minutes – our ZEN Quick-Start video shows how!

How do I tell if my smoke alarms are interconnected?

It is not possible to tell if smoke alarms are interconnected simply by looking at them. There is one certain way to find out if smoke alarms are interconnected though, and that is by testing them. Press the test button once on any smoke alarm in the group (or use the optional remote control), and if they are interconnected then all smoke alarms should activate their audible alarm and flashing red LED, usually within about 5 seconds of the first one starting.

How do I stop my interconnected smoke alarms going off?

As per Australian Standard 3786:2014, all ZEN interconnected smoke alarms will activate their audible alarm when smoke is detected by any one alarm in the group, however, only the source alarm detecting the real smoke will also flash its visual red LED – this allows you to quickly identify which room the fire may be located in. Additionally, if all ZEN interconnected smoke alarms are going off, pressing the silence button on any alarm in the group (or by using the remote control) will silence them, except for the one source alarm which is detecting the real smoke, again allowing you to instantly identify which room or area where the problem is located. Pressing the silence button a second time will then silence all interconnected smoke alarms in the group. Easy.

With the onset of Australia’s winter season, the drop in temperature naturally means we turn to heaters, fireplaces, electric blankets and other devices to keep warm. Believe it or not Queensland can experience some chilly winter nights, and certain parts of the state also receive snowfall. Whilst heating devices provide much-needed comfort, they also increase the risk of household fires. Fire services right across Australia report a significant uptick in house fire call-outs during the colder months. If our risk exposure to household fires increases during winter then it makes sense that smoke alarms should form an essential part of home safety. Ensuring your photoelectric smoke alarms are interconnected, functional and properly maintained can make all the difference in preventing fire-related tragedies this winter. This article will explore home fire safety tips and hacks to keep you and your loved ones safe during winter time.

Interconnected Photoelectric Smoke Alarms

Why Interconnected Smoke Alarms Matter In Winter

Interconnected photoelectric smoke alarms are your first line of defense in detecting fires early. When a fire breaks out, every second counts. Winter is Australia’s peak house fire risk period – a working interconnected fire alarm provides the crucial warning needed to escape safely. According to Queensland Fire and Emergency Services (QFES), having a working interconnected photoelectric smoke alarm doubles your chances of surviving a house fire in winter.

Where Do I Install Photoelectric Smoke Alarms?

Ensure you have smoke alarms installed inside every bedroom, in the hallways outside sleeping areas, and on every level of your home. The smoke alarms should be interconnected so if one alarm activates, they all do. Even though ZEN Smoke Alarms are suitable for both wall and ceiling mounting, it is preferable to install smoke alarms on the ceiling, as smoke rises. If installing on a wall, position them high, but at least 30 cm away from corners to avoid dead air spaces. Avoid installing smoke alarms near open windows, doors, or ducted air vents where drafts might interfere with their operation.

Clean And Test Your Photoelectric Smoke Alarms

At The Onset Of Winter

You want your interconnected smoke alarms to work when you need them most. Throughout the year, dust, cobwebs and other foreign particles can accumulate in and around your smoke alarms, reducing their effectiveness. Give them a clean at the start of winter time – gently vacuum the exterior of the fire alarm with a soft brush attachment from a vacuum cleaner, removing any dust or debris as you do so.

Test your photoelectric smoke alarms monthly to ensure they are a) functioning and b) interconnected.

ALL alarms should activate their audible and visual indicator (red LED) within 10 seconds of the first one being pressed. ZEN photoelectric smoke alarms can be tested by pressing the centre surface once on any alarm, or by simply pressing the test button once on the optional remote control. ZEN Smoke Alarms test mode will silence automatically after approximately 10 seconds.

Heating Equipment – Winter Safety

One of the primary causes of household winter fires is the misuse of heating equipment. Whether you use space heaters, fireplaces, or electric blankets, it’s important to follow basic safety guidelines (often forgotten). Space heaters should be kept at least one meter away from flammable materials such as curtains, bedding, and furniture. Do not place clothing on or near the heater as this creates a fire risk. Ensure the heater is on a stable surface and never leave it unattended, especially while sleeping.

Fireplaces In Winter

Fireplaces should be inspected at the start of winter and cleaned regularly to prevent the buildup of creosote, a highly flammable byproduct of burning wood. Use a fire screen to catch sparks and embers, and always extinguish the fire completely before going to bed or leaving the house.

Electric Blankets

Electric blankets and heating pads should be checked for frayed cords or damage before use, and never folded or left on for extended periods. To test an electric blanket lay it flat on top of the bed, then switch it on for five minutes before putting it on the bed for use to confirm it is okay.

Winter Wheat Bags

Wheat bags are designed as therapeutic aids to be placed on the body and are not designed as a heating replacement for water bottles in the bed. Be very careful not overheat the wheat bag in the microwave – constant re-use can result in the reduction of the moisture content of the wheat, causing it to overheat resulting in fires or burns. Leave wheat bags to cool on a non-combustible surface (such as the kitchen sink) and don’t reheat the bag until it has completely cooled. Check the life of the wheat bag according to manufacturer’s instructions.

Safe Use Of Electrical Appliances In Winter

Winter often sees an increased use of electrical appliances, which can overload circuits and cause fires. Avoid using multiple high-wattage devices on the same outlet, and never use extension cords for long-term appliance connections. Check all cords for wear and tear, and replace any damaged ones immediately. Choose electrical power boards which contain inbuilt overload protection.

Kitchen Safety During Wintertime

Winter brings an inclination for hearty meals and more cooking. Ensure that your kitchen is a fire-safe zone by never leaving cooking unattended and keeping flammable items (tea towels etc.) away from the stove. It’s always wise to have a ZEN fire blanket easily accessible in the kitchen and to know how to use it effectively.

Create And Practice A Home Fire Escape Plan

A smoke alarm is most effective when paired with a well-rehearsed home fire escape plan. Make sure everyone in your household knows the sound of the smoke alarm and understands what to do when it goes off. Plan two ways out of each room and designate a meeting place outside your home. Practice your fire escape plan twice a year (including at the start of winter) to ensure everyone is prepared.

Conclusion – Winter Fire Safety And Your Smoke Alarms

Winter is a great season to enjoy the warmth and comfort of home (and also the reduced humidity in QLD!), but it is also a time to be vigilant due to the increased risk of household fires. By taking the time to properly install and maintain interconnected photoelectric smoke alarms, sensibly using heating equipment and electrical appliances, and by creating a solid fire escape plan, you can keep your loved ones safe and sound. Stay warm, stay safe, and ensure your photoelectric smoke alarms are ready to protect you from winter’s hidden dangers!
