How a Heat Detectors Works

Every day, in the United States, 1,500 houses burn. Often, these fires are preventable, common house fires that were noticed too late. Fires only take a couple of minutes before they become uncontrollable, with flames reaching over 1,000 degrees Fahrenheit. House fires are dangerous, killing 6,500 and injuring 280,000 people every year.

The good news about fires is that, if they are caught before the flames escalate, the fire is easy to handle and easy to put out. Heat detectors and fire detectors save thousands of lives every year. Here's how a heat detector can save your home.

Types of Fires for Heat Detection

Low-Energy Fire

There are two main types of fire: low-energy fires and high-heat fires. A low-energy fire smolders; it consumes fuel slowly and gives off a lot of smoke. However, this type of fire emits very little heat. Because this fire gives off more smoke than heat, thermal detection may fall short and take too long to detect this fire. By the time the heat sensor is activated, the fire will have caused severe damage to the home.

High-Heat Fire

The second type of fire is a high-heat fire. A high-heat fire consumes fuel quickly. As the fire eats, the flames grow higher and higher. These types of fires can be caused by an explosion or combustion. These fires feed off of easy-to-burn material such as paper, hay, or dry wood. This fire will trigger a heat detector fairly quickly. Heat Detectors are optimal for sensing this type of fire.
