2. Flame detector - Wikipedia

   en.wikipedia.org/wiki/Flame_detector

   A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.

3. Optical beam smoke detector - Wikipedia

   en.wikipedia.org/wiki/Optical_beam_smoke_detector

   An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, [1] typically as an indicator of fire. [2] They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical [ 3 ] or restricted for use by the height of the building.

5. Smoke detector - Wikipedia

   en.wikipedia.org/wiki/Smoke_detector

   A photoelectric, or optical smoke detector, contains a source of infrared, visible, or ultraviolet light—typically an incandescent light bulb or light-emitting diode (LED)—a lens, and a photoelectric receiver—typically a photodiode. In spot-type detectors, all of these components are arranged inside a chamber where air, which may contain ...

6. Fire detection - Wikipedia

   en.wikipedia.org/wiki/Fire_detection

   Fire detectors sense one or more of the products or phenomena resulting from fire, such as smoke, heat, infrared and/or ultraviolet light radiation, or gas.. In dwellings, smoke detectors are often stand-alone devices.

7. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   The first gas detector in the industrial age was the flame safety lamp (or Davy lamp) was invented by Sir Humphry Davy (of England) in 1815 to detect the presence of methane (firedamp) in underground coal mines. The flame safety lamp consisted of an oil flame adjusted to specific height in fresh air.

9. Infrared open-path detector - Wikipedia

   en.wikipedia.org/wiki/Infrared_open-path_detector

   This linear 'sensor' is typically a few metres up to a few hundred metres in length. Open-path detectors can be contrasted with infrared point sensors . They are widely used in the petroleum and petrochemical industries, mostly to achieve very rapid gas leak detection for flammable gases at concentrations comparable to the lower flammable limit ...
