A small fire can quickly grow and spread, making it vital to be alerted to the problem as quickly as possible. Protecting your family and North Scottsdale, AZ, home means ensuring you have the right type of smoke alarm in the right location. As the first line of defense regarding fire safety, it is important to understand alarm basics.

Types of Alarms

There are different kinds of fires, which means you may need a different type of smoke detector in certain areas of the home.

Ionization: This type quickly takes flaming fires. A minute amount of radioactive material sits between two electrically charged plates. This creates a current between the plates. If smoke enters it, the electric flow is disrupted, which activates the alarm. Since these are sensitive to smoke, that can be accidentally set off if placed while cooking.
Photoelectric: Best-suited for smoldering fires, they have a sensing chamber that has a light source aimed away from the actual sensors. Once smoke enters the chamber, light is reflected and triggers the alarm. These more quickly detect smoke, making them suitable for kitchen placement.
Combination: Some alarms are available that feature both technologies, which makes them a great choice for bedrooms.
Smart Alarms: Technology has allowed for the three types of alarms to be interconnected and easily accessed through an app, along with other high-tech perks.

Alarm Placement
So, where should a smoke alarm be placed? It is recommended that one be located on each floor of the home, as well as inside each bedroom. There should also be one in the attic, basement, and garage. They should be at least 10 feet from cooking appliances, as well as away from windows, doors, and air ducts. The size of your home should also be considered. In general, a smoke alarm covers a radius of 21 feet and approximately 1,385 square feet.
When an emergency arises, quick action and detection is imperative for everyone’s safety. Ensuring you have a smoke alarm in recommended locations boosts the safety factor. Once everyone is safe, you can leave the property damage to a fire and smoke restoration expert.
