The Smoke Heat Freeze Detectors are designed to recognize smoke from common synthetic materials and decrease nuisance alarms from everyday cooking. Using advanced detection algorithms and a sophisticated photoelectric optical sensor, these two detectors meet the new UL standards.

Traditional smoke detectors trigger an alarm when any smoke density reached a specific level, which could have just been normal cooking events. This Smoke Heat & Freeze Detector uses advanced algorithms and a sophisticated optical chamber to improve the detection of smoke particles created by some synthetic materials, separate from organic smoke associated with normal cooking events.
