Ultraviolet Fire Detection
Ultraviolet (UV) detectors work with light wavelengths. These types of detectors detect
fires and explosions within 3–4 milliseconds due to the UV radiation emitted at the
instant of their ignition. Because false alarms can be triggered by artificial UV
sources, they are not optimal in environments where they may encounter UV sources
such as lightning, arc welding, radiation, and sunlight. In order to reduce false alarm a
time delay of 2-3 seconds is often included in the UV Flame detector design.

Infrared Fire Detection
Infrared (IR) flame detectors work within the infrared spectral band. Hot gases emit a
specific spectral pattern in the infrared region, which can be sensed with a type of
thermographic camera called a thermal imaging camera. Typical response times for
infrared fire detectors is between 3 and 5 seconds.
