Nuisance alarms reduced by up to 46% by using variable sensitivity and time delay based on smoke changes just before and after fire alarm level has been reached; A learning function will ensure that the most suitable fire alarm algorithm is always used; High-tech mesh net prevents dust and insects to enter the detection chamber
Smoke detector - Wikipedia
Smoke detectors/Alarms are usually housed in plastic enclosures, typically shaped like a disk about 125 millimetres (5 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary. Smoke can be detected either optically (photoelectric) or by physical process (ionization). Detectors may use one or both sensing methods.
