UV / IR Combined Detectors
This type of detector combines the two technologies (gate AND between "UV channel" and "IR channel") and provides excellent rejection of false alarms and good detection distance. However, UV / IR combined detectors suffer from the combined limitations of UV and IR detectors.

UV / IR2 Combined Detectors
The combined UVIR detector using a performant UV sensor is limited in terms of detection range (a distance of detection), by the infrared part.

The IR sensor is curbed to keep a “reasonable” activation of the IR chain by the surrounding thermal background. By using extra information in the IR band, via a second sensor, this increases the gain of the amplification chains of the detector and thus increases the detection range, and at the same time maintains a good immunity to false alarms.

Multi-IR Detectors
The present market is obviously geared towards multi IR detectors. The aim is to remove the multiplying information and UV in the IR domain. A large number of devices depend on the CO2 IR band at 4.4 micron, but there are some devices that use the H2O IR band (2.9 microns) in order to detect ammonia or hydrogen fires.

Usually, multi IR detectors possess a longer detection range and maintain an extremely low rate of false alarms. In addition, these detectors are insensitive to attenuations related to oil vapors and fumes as well as other interference sources like a welding arc, lightning, etc. Again, the idea is to increase the gain of a detector’s amplification chain and select the wavelength and suitable signal treatments.

Three IR detectors are generally used in three different spectral bands, reaching detection ranges between 40 and 80 meters on standard heptane standardized fires, even in the presence of many interfering IR sources in the environment.
