Wireless Smoke Alarms

Legislation dictates that all homes in our state must have interconnected smoke alarms within the next two years. Interconnecting wired smoke alarms are sometimes tricky, which is why we recommend opting for wireless smoke alarms instead. In this article, we unpack the advantages of using wireless smoke alarms, along with some options available on the market.

The necessity of Interconnected Smoke Alarms

Smoke alarms detect smoke or carbon monoxide in their immediate vicinity, sounding the alarm and allowing you to react quickly in case of emergency. With standalone smoke alarms, only the alarm that detects the smoke will sound its siren. If you’re out of earshot, you won’t hear the bell and thus not react in time.In the case of interconnected smoke alarms, all units sound the alarm when one unit detects smoke or carbon monoxide. Here, you have a higher chance of hearing the signal and thus reacting in time. If you installed a smart system, these alarms connect to your smartphone, allowing you to respond even when you’re not at home.In short, interconnected smoke alarm systems are much safer than their traditional counterparts.

Advantages of Wireless Smoke Alarms

Wireless smoke alarms are by their very nature interconnected since they all have wifi capability, thus connecting to nearby devices. Here are some advantages to using these instead of the traditional hardwired models.

Easy Installation & Maintenance

Wireless smoke alarms are quick and easy to install. They either bolt or stick to the ceiling, so you’re done in a matter of minutes. In contrast, wired smoke alarms require professional installation.

Maintenance is quick and easy for the same reason. When performing maintenance on a wired smoke alarm, you must switch off the main power supply and preferably have a professional do the actual work. On the other hand, you can do maintenance on a wireless smoke detector yourself, usually through the accompanying app.

It’s Cheaper

It’s far easier to interconnect wireless smoke alarms than their traditional hardwired counterparts. Interconnecting hardwired smoke alarm systems are potentially expensive since it usually requires costly retrofitting that only trained professionals can do.

You can interconnect wireless smoke alarms yourself, using the accompanying app or other user-friendly methods, depending on the model you chose. You save twice: first on the expensive professional call-out, second on the hardware needed for interconnection.

Greater Coverage

Since all your smoke alarms will sound the moment one of them detects smoke, you will hear your smoke alarm regardless of where you are. This interconnectivity gives you more time to react and retreat to safety in the event of a house fire.

Battery Operated

Wireless smoke alarms are usually battery operated. If the power goes out, your smoke alarm will still work, offering you the peace of mind that you’ll know of any fire the moment it starts. In many cases of housefires, power outages occur as a result of the fire, rendering the smoke alarm useless.

They're Smart

Some of the newer wireless smoke alarms come with voice and location alerts. When the alarm sounds, it notifies you which unit detected the smoke and the nature of the emergency. In this way, you know where the danger is and how serious it is, enabling you to react quickly and appropriately.

Wireless smoke alarms connect to your home wifi network – that’s how they interconnect with each other. This connectivity allows the smoke alarm to connect with your phone as well, alerting you the moment one of your units detect smoke. So, even if you’re not at home, you will know where the danger is and how serious it is. Here, you can react immediately, saving lives and minimizing damage to your property.

If you have a smart home, this is even more useful, since you could trigger emergency measures from anywhere in the world.

Options for Wireless Smoke Alarms

There are many wireless smoke alarms on the market. Choosing the best fit for your home could be overwhelming, and you might not know which brands and models are reliable. We’ve rounded up some brands with proven reliability for you to choose from:

Google Nest

This is our top option. As part of Google’s Smart Home innovations, Google Nest smoke alarms interconnect seamlessly. Here, you could either install wired or battery-operated units. All their models use wifi to connect through a protocol called Weave.

Weave is a smart hybrid, using direct connections and using your home wifi network interchangeably. If your home wifi network is available, your smoke alarms will connect to this, allowing you access to the units from anywhere in the world. If for any reason, your home wifi network is unavailable, the Google Nest units will connect using dedicated low-powered wifi signals. So, your units will continue functioning together, even if your wifi is disconnected. On a practical level, you have the benefit of interconnected smoke alarms under all circumstances.

If one of your Google Nest smoke alarms detect smoke or carbon monoxide, all units will sound the alarm, after first indicating the location of the emergency. In other words, it will physically tell you, “smoke detected in the kitchen” before the alarm goes off.

The video below explains how it works quite nicely. It’s worth watching if you’re at all interested in Google Nest Protect. Even if you’re just hear wondering, what makes a smart smoke alarm different from a normal one, this is the video for you.The Google Nest Protect does so much more than you’d image. 


Honeywell offers top-notch smoke alarms with a built-in wireless transmitter. These connect to your home wifi receiver and have an impressive range of functions. They also eliminate nuisance alarms by using a smoothing algorithm. This algorithm smooths out short-term spikes from smoke and dust, which would trigger many other smoke alarms currently on the market.

Information on alarm signals, tampering, maintenance, and battery conditions get sent directly to your connected device. The Smart Check feature even tells you when to clean your smoke alarm.

Honeywell smoke detectors are quick and easy to install, even on difficult surfaces, like stucco. A sturdy mounting base allows for installation in any location you require.


Xiaomi collaborated with Honeywell to create a smart smoke alarm with advanced wifi capability. This product integrates seamlessly with other Xiaomi intelligent home systems.

The Xiaomi smoke alarm doesn’t connect directly to your home wifi network. Instead, it connects with a Xiaomi gateway device – part of their smart home solutions. If you already have a gateway device, linking your new smoke alarm is quick and straightforward, using the Xiaomi Mi Home app. Here, device settings allow you to specify the device location (kitchen, bedroom, etc.) – this allows the unit to indicate the location where smoke is detected.

When the Xiaomi smoke alarm detects smoke, it sends a message directly to your smartphone, tablet, or other connected devices, using the Xiaomi Mi Home app. You can also set up some automation rules on the app. For example, when the smoke detector sounds the alarm, turn on all the lights in the house. In the device settings, you can specify whether you expect any levels of smoke in the installation location. For example, there is bound to be some smoke in the kitchen, while a no-smoking office environment should have none. These settings automatically adjust the alarm’s sensitivity settings, minimizing nuisance alarms.

A self-check, activated on the app, checks all alarm settings and notifies you of any errors found. You have to initiate the self-check manually, although the app allows you to set a reminder for this. Additionally, the app keeps a log of all events logged by your smoke detector, which could be useful in the long run.



Quell offers a range of wireless interconnected smoke alarms that are quick and easy to install. These alarms designed with specific locations in mind – kitchen, living room, bedroom, and hallway – adjusting the sensitivity according to the target location. This sensitivity adjustment minimized nuisance alarms.

All Quell alarms come with a 10-year battery already installed. Since smoke alarms must be replaced every ten years, this battery lasts the entire lifetime of the device – you never have to worry about replacing it. These alarms interconnect seamlessly, so when one unit detects smoke, all the alarms in your home will sound. It won’t tell you where the smoke was detected, however.
