Having a smart smoke detector in every home is the first key step toward your home’s safety. The smart technology doesn’t only sound the alarm, it will also notify your smartphone and other smart devices connected to it. 

A traditional smoke detector will be able to warn you of danger, but not if you aren’t home to hear them. With a smart smoke detector, you can monitor and control your home even when you are away.

Smart smoke alarms are one of the most useful and crucial categories of smart home devices and for something so important to home and personal safety, they seem to lack attention compared to home security systems.

Did you know? The National Fire Protection Association (NFPA) reports that 40 percent of residential fire fatalities occur in homes without functioning smoke alarms. Having a properly working smoke alarm can lower the risk of death in a house fire by 55 percent. A reliable and effective smart smoke and CO detector system can alert you quickly to get you and your family to safety. And if you travel frequently or have multiple homes and premises to monitor, it will give you greater peace of mind.


What Is a Smart Smoke Detector?


Similar to regular smoke detectors, smart smoke alarm systems have sensors that will sound a warning alarm once smoke is detected. The biggest difference is that smart detectors are WiFi enabled which will communicate with your home security system and send voice alerts and notifications to your smart devices through their compatible app. By utilizing connective technology, homeowners can remotely monitor fire emergencies, receive status notifications, interconnect with other smart home devices and even shut off false alarms using voice commands. Smart smoke detectors are meant to increase effectiveness and reduce manual home alert system maintenance.


Benefits of Smart Smoke Detectors


Reliability and Battery Life

Smart detectors have automated self testing and low battery notifications so you can be assured that it is always working. 


Ability to Detect Fire Faster

Compared to regular smoke detectors, smart smoke alarm systems have the ability to detect fire faster as they will identify when an area is too hot or shows a significant increase in temperature.


Interconnectivity and Notification Services

Anyone with access to the app connected with the smart smoke detector system will be able to receive a variety of different notifications and alerts to warn about a fire occurring even while being away from home.


Tells the Exact Location of the Fire

Smart detection can notify homeowners of the exact nature and location of any fire hazard detected in the home allowing users to guide family members to a safe exit without any panic.


Stop False Alarms with a Press of a Button

In case of false alarms, many smart smoke detector alarms can be easily silenced through the smartphone or other smart devices.


Common Types of Smart Smoke Detectors


Before deciding on the best smart smoke detector for your home, it is important to understand the different types of smart smoke alarm systems available in the market today. 


Battery

Battery operated smoke detector systems which most commonly use a replaceable 9-volt battery, are the easiest to set up. These detectors are unaffected in the event of a power outage but require a regular check typically every six months to ensure they are operational. Newer smoke alarms are designed with lithium batteries that are known to last up to 10 years without needing to be replaced.


Hard Wired

Hard wired smart smoke detectors are connected to the home’s electrical circuit, making it more dependable. As long as there is power, these detectors will work. Worry not, most hard wired detectors have a backup battery to ensure they continue working in the event of a power outage. Initial installation or maintenance of the unit is more challenging compared to the battery operated systems and would require the help of a professional electrician. 


Ionization Sensors

Ionization smoke alarms respond faster to flash fires but are less effective at detecting smoldering fires. Ionization sensors are more prone to produce false alarms triggered by cooking fumes, causing nuisance alarms to happen too easily. It is also important to note that the most common types of home fire are caused by flaming fires from the rapid burning of combustibles like newspapers and cooking grease. 


Photoelectric

Photoelectric smoke alarms use infrared light to detect smoke and respond quicker to smoldering, slow-burning fires. Electrical shortages, cigarettes, and fireplace embers are one of the most common causes of slow-burning fires. These fires produce a large amount of smoke and can burn for longer periods of time. 


Split Spectrum

The USFA recommends equipping homes with both ionization and photoelectric sensors for maximum protection. The split spectrum system contains both. While they usually cost more, they provide a more comprehensive fire detection for additional safety. 


What to Look for When Choosing the Best Smart Smoke Detector


A reliable, safe and easy-to-use smart smoke alarm is a definite must-have in every home. But as a smoke alarm can range in price, you would want to make sure you are getting the best option for your dollar. The more features it has, the higher the price. Before you make a purchase, let’s dive into some of the most prominent features available. 


Detects Smoke and Carbon Monoxide (CO)

Carbon monoxide is a colorless and odorless type of gas produced by burning fuel in vehicles, fireplaces, furnaces, and other gas ranges. Carbon monoxide detection is an increasingly common feature on smart smoke detectors, allowing you to monitor both smoke and carbon monoxide threats for your home. Smart smoke alarms with built-in carbon monoxide detectors eliminate the need to maintain and monitor two separate detectors, offering you a safer and more efficient household.


Ease of Installation

As discussed earlier, a smart smoke detector comes in both hard wired and battery operated options. Hardwired alarms are more difficult to install as it most often requires the help of a professional electrician but is more dependable. Battery-operated alarms on the other hand can be installed easily and most modern smart smoke detectors come with in built lithium smart batteries that can last up to 10 years. 


Sensitivity and False Alarms

Some smoke detectors are designed to be more sensitive than others. Given that the alarm will only be triggered when something goes wrong, it is very difficult to know if it is functioning properly. Occasionally, some smoky conditions like a burning dish in the oven would set the alarm off, revealing how sensitive the detector is. As long as the smoke detector is located within the recommended area, tested regularly, and maintained dust free, it should function as expected.    


Safety and Performance Certified

When choosing a smoke alarm system, an Underwriter Laboratories (UL) certified alarm is guaranteed to detect smoke and CO in the home. UL is a globally recognized, third-party certification company that tests the efficacy and safety of homes for more than 40 years. 


Interconnectivity

It is recommended that homeowners should have multiple smoke detectors for different areas of the home, making interconnectivity an important specification for most smart homes. Many of the best smoke detectors offer an interconnectivity feature, so if one alarm goes off, all the units will go off as well even if only one detects smoke. 


Types of Notification

Most smart smoke detectors will sound the siren and send alerts directly to the smartphone. These warnings can come in the form of voice alerts or push notifications through the app. Depending on the model of the smoke detector, users can customize and manage the level of information. They can tell users what type of hazard and the location of the hazard and how to respond. Smart batteries will send notifications when the battery is low and can also silence false alarms. There are also color-coded strobe light alarm notifications available in some models for the hearing-impaired.


Multiple users

It is crucial that you choose a system that supports multiple users. If more people receive a push notification that there is a fire in the house, the faster the response. Every house member should be granted access and temporary access could be given to neighbors or nearby family members when homeowners are out of town. 


Smart Home Support

Integration is key. If you are beginning to build your smart home or already own multiple smart home devices, you would want to integrate your smoke detector with the rest of your home seamlessly. Having major smart home hubs like Alexa, Nest, SmartThings or HomeKit helps you reduce the need to maintain multiple apps on smart devices.


Smart Tech Compatibility

Most smart smoke detectors are now compatible with other smart home systems. While some models only work with specific types of smart hubs, there are other stand alone detectors that can work with any type of mobile device. Adding a smart listener to the existing traditional smoke alarm system can turn it into a smart device without costing too much.


Where to Place Smoke Detectors in Your Home


For optimum smoke detection, smoke alarms should be placed on the ceiling of every bedroom, passageway, kitchen, living area, and basement in the house. Having a sufficient number of properly installed smoke detectors is an important step in protecting your home. It is recommended that smoke detectors should be placed at least four inches away from ceiling corners as they need access to circulate air. 

Placing smoke detectors in unfavorable locations can result in recurring false alarms. Most professionals do not recommend placing smoke alarms in these locations:

  • Less than four inches of wall or ceiling corners
  • Near stoves or any other cooking appliances
  • Places with extreme temperatures
  • Bathrooms
  • Near windows
  • Near vents and fans
  • Garages
