The “UDY GUIDE” gives insight into the various types of heat detection equipment.

These systems are commonly used by homeowners to detect burning fires within their properties. For more accurate detection, modern heat detectors use sensors and microphones, as well as cameras that use infrared light. Most heating elements will give off the characteristic pattern of light in the IR spectrum, which the sensors detect.

Heating detection systems employ either audible or visible sensors to locate heat signatures inside the structure. Both heat detectors must have access to a clearly visible line of sight to perform their function. In residences, these sensors are usually located in hallways and living rooms for as broad a coverage of the home as possible. Infrared radiation is determined by these sensors. This spectrum is used to determine the fire’s relative intensity.

Infrared sensors look for a particular pattern of the infrared radiation that is emitted by the object at the temperature of ignition. If an object attains the appropriate temperature, an alarm sounds. In the event, firefighters are alerted that there is a fire within an area that the detection system is monitoring.
