Types of Heat and Smoke Detection Sensors

There are 4 main types of sensors that are designed to detect the presence of fire. Knowing the difference between heat and smoke detection sensors is important as it lets you define which sensor is perfect for your application.

These types of heat and smoke sensors include heat, photoelectric, ionization, and ionization/photoelectric smoke detectors. The disparity between the four types is how they detect fire, heat being from temperature while the other three being from the smoke. The perfect smoke detection sensor is a mixture of ionization/photoelectric.

  • Heat detection sensor

Heat detection sensors are designed to detect the presence of heat and rise in air temperatures. These sensors tend to have false alarms, but they can take longer to identify a fire than a smoke sensor. They are perfect in circumstances where smoke sensors might cause a false alarm like humid, steamy, or dusty surroundings. Rarely occupied places like storage places, machine rooms, and warehouses also utilize this kind of sensor.

The three common types of smoke sensors include photoelectric, ionization, and a mixture of ionization/photoelectric. Any smoke detector sounds an alarm whenever they detect smoke such that the occupants of the building can know what is happening. What differentiates these gadgets from each other is how they identify the smoke.

  • The Photoelectric Smoke Detection Sensor

The photoelectric smoke detection sensors have gained tremendous popularity due to their effectiveness. They come with a beam of light in the gadget, and whenever smoke disseminates the light, it makes the alarm to ring. This kind of smoke detector is faster to detect even smaller smoldering fires than the ionization smoke detection sensor. While they are extremely reliable, they can make a few false alarms.

  • Ionization Smoke Detection Sensor

Ionization smoke detection sensors come with a constant electrical current that happens between two metal plates in the detector. Once the smoke enters the device’s chamber, it disrupts the electrical current and makes the alarm to ring. These smoke detection sensors are ideal for identifying fast-burning fires.

  • Ionization/Photoelectric Smoke Detection Sensor

A mixture of smoke detection sensors is an excellent way to safeguard your building and its occupants from fire. When the two types of smoke detection sensors work together with one a single gadget, it helps to make sure that irrespective of the form of fire, the device will identify it as soon as possible.

In some cases, a collection of heat and smoke detection sensors will be installed in a building. A professional will offer you a smoke detection solution that fits your building’s needs.
