Factors to Consider When Buying WiFi  Smoke Detectors

Many smoke detectors have flooded the market, so choosing one can be tricky. But with a bit of know-how, you should get a proper unit that aligns with your needs. We’ve created this buying guide to make your decision easier. Check below:

  • Power Source

The source of power for WiFi smoke detectors is similar to traditional detectors. You can choose between battery-powered and hardwired detectors.

Essentially, battery-powered models have replaceable batteries that you must check and replace periodically, while hardwired models are connected to your home’s electrical grid to remain powered throughout.

Hardwired detectors also come with backup batteries in case of power outages. We recommend battery-powered models since they are easy to install and offer unlimited features.

  • Sensors

Smoke detectors use two types of sensor technologies: ionization and photoelectric. Photoelectric sensors are more responsive to fires that have been smoldering for a while, whereas ionization sensors excel in picking up on flaming fires. Since dangerous house fires vary, we recommend having both sensor technologies in your home.

  • Interconnectivity

Interconnectivity is the ability of smoke detectors to interact with each other, alerting the system to a problem. For instance, if a fire breaks out in an attached garage, the entire system in your home will activate immediately.

Fires can double in size very quickly, so if you are asleep, you may not hear a standalone smoke detector activate in the garage. Choose interconnected detectors to get alerted to an issue before it’s too late.

Types of Smoke Detectors

The three main types of smoke detectors are ionization, photoelectric, and dual. Though these units do the same job, they go about it differently.

  • Photoelectric

These detectors incorporate an LED light in the chamber, which shoots a beam across the chamber. It also has a sensor that sits roughly 90 degrees from the LED. In normal conditions, the sensor cannot see the LED beam, but when smoke particles infiltrate the chamber, the light reflects off smoke particles, and the sensor detects the beam.

The sooner the sensor detects the beam, the alarm triggers. These types of smoke detectors are good at detecting smoldering burns.

  • Ionization

While these detectors use radioactive materials, alpha rays, and other sophisticated technology, they have a simple working mechanism. A chamber fills with ions, which are held together by electrical charges. A sensor in the chamber is aware of the number of ions contained within.

When smoke particles penetrate the chamber, they release some ions, compromising the sensor’s count and triggering the alarm. These types of smoke detectors are suitable for detecting actively flaming fires.

  • Dual Sensor

As the name implies, these smoke detectors employ both types of sensors. It pays to use both sensors to detect threats across various materials that might be burning quickly.

How Many WiFi Smoke Detectors Do I Need for My Home?

At a minimum, you should have at least one smoke detector on every floor of your house, outside sleeping areas, inside bedrooms, and near stairways and living spaces. However, the number of smoke detectors is based on numerous factors, including your home’s layout, size, and so on.

  • Size and layout: Homes with multiple rooms need more smoke detectors to guarantee adequate coverage. Examine your home’s layout and see whether some areas are far from the main living spaces.
  • Consult with a professional: If you are unsure about the placement and number of WiFi Smoke Detectors, consult with a fire safety expert. They should offer personalized recommendations depending on your home’s unique characteristics.
