FAQs About Smart Smoke Detectors

Still not entirely sure what to expect from a smart smoke detector?

Read through this FAQ, and we’ve got you covered on all the queries you may have before deciding what the best smart smoke detector is for you.


Q: What does a smart smoke detector do?

A smart sensor first and foremost does what all regular smoke detectors do: they let you know when they sense a fire in your home.

What makes a smart detector “smart” is its ability to alert you with a notification on your phone, so if you’re not at home, you’ll be able to take swift action.

Some more advanced smart detectors also monitor the air quality of your home and even the weather.

They can also alert you when your batteries are low, bypassing the annoying beep that traditional smoke detectors emit when their power fails.


Q: How do smart smoke detectors work?

To understand how the best smart smoke detectors work, they’re best thought of as Wi-Fi-based smoke alarms.

Their basic function is the same as a traditional smoke alarm: if the detectors in the device detect smoke or fire, the alarm is triggered until someone turns it off.

The best smart smoke detectors come in various types, including ionization, photoelectric (otherwise known as an optical smoke detector), and carbon monoxide/dioxide detection, each of which utilizes a specific type of sensor.

Smart smoke detectors can sometimes feature voice-activated controls and can even be modified to help alert people who are hard of hearing by activating vibrating pillow pads and remote warning handsets.

The advantage to smart smoke detectors is that users are able to control the alarm from their mobile phone or other devices, using an app to turn the alarm off (which comes in handy if someone accidentally burns their toast and triggers a false alarm).


Q: What are the benefits of a smart smoke detector?

Smart smoke detectors are a great introduction to an existing smart home, first and foremost for the obvious reason: they’ll let you know if there’s a potential fire.

Additionally, you can set up multiple smart smoke alarms which sync up with one another, so if one alarm is triggered, all of them will go off.

The ability to receive notifications on your smart smoke detector elevates its utility above what you can expect from a traditional smoke detector.

This effectively gives you 24/7 monitoring whether you’re at home or not, so you can be guaranteed peace of mind even if you’re on holiday.


Q: Where do you place a smart smoke detector?

As with traditional smoke alarms, a smart smoke detector is fitted to the ceiling as centrally as possible within the room they are installed.

How many you have around the house varies from household to household. 

Typically, smoke alarms cover each level of a home, including bedrooms (sometimes placed within 3 meters of bedroom doors to cover more than one bedroom at once) and in attics and basements.


Q: Should you put a smoke detector in the kitchen?

The old style of fire alarm typically worked poorly when it came to dealing with the heat from kitchens.

These were known as ionization detectors and were prone to endless false alarms.

Smoke alarms constructed with photoelectric detectors or dual-mode detectors, on the other hand, will work closer to the kitchen, but you still want to avoid placing them directly inside the kitchen area.

If you’re looking into buying a smart fire alarm and are concerned about kitchen use, checking the type of detector it uses should be your first step.

Choosing the right one will mean far fewer “nuisance alarms” to deal with. 

So, if you make sure to install it slightly away from the kitchen (for instance, in an adjacent dining area), it’ll work more effectively.


Q: Where should smoke alarms not be placed?

Care should be taken to avoid mounting smoke alarms too close to other heat sources such as fireplaces and cookers, as these devices will likely trigger false alarms.

Likewise, you’ll need to make sure you can access them for maintenance, so avoid placing them over the stairs and other inaccessible areas of the house.

Placing them directly in your kitchen – particularly over the hobs – is a big no-no for obvious reasons.

Try to ensure any smart smoke detectors you have nearby are at least 10 feet from the stove.

The best smart smoke detectors can even tell the difference between different types of fires, but even these shouldn’t be installed too close to regular heat sources.


Q: How many smoke detectors should be in a house?

According to the National Fire Protection Association (NFPA), you should install a smoke detector on every level of your home, including the basement.

With the advantages of a wifi smoke detector setup, however, it’s feasible to install smart smoke detectors throughout the house.

Covering the bedrooms in the house should be a priority, and if you can’t cover all bedrooms, then placing them on the hallway or landing outside, close to the bedroom doors.

If there are any especially large rooms in the house, it may be worth adding a second smoke alarm to ensure the room is fully covered. 

The more smoke alarms you have installed in your home, the better, provided you place them correctly and avoid putting them close to vents or windows since smoke could drift through these openings before your alarm has a chance to activate.


Q: How often should smoke alarms be maintained?

When looking into testing and maintaining your smart smoke detector, first, you should always check the manufacturer’s guidelines.

This will include information on any warranty or guarantee that comes with the product and the relevant instructions for properly checking the device.

Given the potential high stakes of a failed or failing smoke alarm, you should take care to test it as frequently as recommended.

Usually, this means checking the alarm is functioning at least once a month, or ideally once a week.

If you’re using a smart smoke detector that features a push notification to let you know the battery is running low, this is one less test you’ll need to conduct manually. 

Most smart smoke detector devices last up to 10 years.

So, if your device is getting old, it might be time to consider replacing it (and if you’re still using the old-style smoke detectors, this could be the perfect opportunity to upgrade to a smart smoke detector).

Over the course of these ten years, a smoke detector is prone to a great deal of wear and tear.

You should be aware of the damage that can come from electrical corrosion, the accumulation of dust particles, and even small insects and other airborne contaminants which can affect their operation.

Always ensure your smart smoke detectors are free from any obstructing objects, and when decorating a room, avoid painting over them.


Q: Do I need a smoke alarm in every room?

While there is no legal requirement for you to include a smoke detector in every room in your house, the general rule of thumb is to install a smoke alarm in every room of the house where a fire could break out.

Ultimately, the more you have, the greater the degree of protection you bring for yourself and your family.

At the bare minimum, you should install a smoke alarm on every floor of your home.

A survey for Which? magazine revealed that only 77% of respondents had covered each floor with alarms, while 22% had failed to do this. 

Deputy Head of Community Safety at the London Fire Brigade, Vicky Lowry, said: ‘Having smoke alarms in your home can save your life.

Homes need working smoke alarms in all areas of risk, or you won’t be properly covered.

This includes any room where you smoke, rooms where you use electrical equipment such as satellite boxes, appliances, computers or heaters, and anywhere you charge your mobile or laptop, including bedrooms.’


Q: Can I replace the smoke detector myself?

Most smart smoke detectors are easy to replace, and if you’ve installed them yourself when you first purchased them, you’ll have a good idea of the processes involved.

That said, if you’re not comfortable dealing with wires, there’s no harm in erring on the side of caution and getting a professional electrician to handle the job for you.

If you’re upgrading to a different brand, make sure you follow the instructions for your new smart smoke detectors.

Be aware that if you don’t fit them according to the manufacturer’s instructions, they may not work correctly, and you could face issues down the line.

If in doubt, consult an electrician, and they’ll help make sure your smoke alarm is replaced correctly.


Q: Is a smart smoke detector worth it?

Anyone serious about fire safety around the home would be wise to invest in a smart detector.

Likewise, if you have a family member with a track record for burning toast, you’ll love a smart smoke detector simply because it’s so easy to turn off false alarms.

They might not be the most fun device in the smart home ecosphere, but installing one could save lives, so on that count alone, they’re an essential investment.

If you’re looking to increase the diversity of smart devices in your home and haven’t already invested in a smart fire alarm, they’re a great way to continue to build up your smart home ecosystem.

Security-conscious consumers can add them to their security cameras and motion sensors collection, transforming a home into an impregnable fortress worthy of a James Bond movie.

Given the range of additional features which come with a smart smoke detector compared to a traditional smoke alarm, you can expect to pay out more money.

Some models are considerably more expensive than a typical 10-year detector, but that said, those aren’t going to notify your smartphone about the potential emergency unfolding in your home.


Q: How To Choose / Which One To Choose

When making your decision for which smart smoke detector to go for, you should always consider your current smart home setup along with the fire safety precautions you need to prioritize.

If you already have a series of smart speakers connected throughout your home, investing in a smart smoke detector that can play music through its onboard speaker won’t be necessary.

Likewise, if you’re on a budget and need multiple smoke detectors throughout the house, choosing a budget device will allow you to meet your needs without breaking the bank.



Every home needs smoke detectors and fire alarms to bring peace of mind, and if you’re looking to upgrade your smart home setup, then smart smoke detectors are a must.

This guide should set you on the path to making the right purchase for your needs and budget, whether you’re looking for something basic or prefer full voice control.
