The Acclimate 2251TMB photoelectric detector by System Sensor of St. Charles, Ill., includes thermal detection at 135° F. It uses advanced onboard software to combine the signals from the photo and thermal elements to create a true multicriteria detector capable of rejecting nuisance sources.
The detector can also adjust its sensitivity according to its environment. Using advanced software, the device continuously samples the air in the environment and adjusts its detection parameters and alarm threshold, accordingly. It does this automatically without user intervention, according to the company.
