The 345 MHz 2GIG 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 for the year 2020. UL 217 & 268 Smoke Alarm Standards bring 250 new technological changes to traditional smoke detection. Meeting the new UL standards, the 2GIG Smoke Heat & Freeze Detector delivers improved smoke detection, including smoke from common synthetic materials found in home furnishings. These synthetic materials generally have a faster burn rate, reducing escape time from an average of 17 minutes to 3-4 minutes (UL Press Release – February 2018).

Traditional smoke detectors trigger an alarm when smoke density reaches a specific level, which could be due to normal cooking. The 2GIG Smoke Heat & Freeze Detector uses advanced algorithms and a sophisticated optical chamber to improve the detection of smoke particles generated by certain synthetic materials, distinct from organic smoke associated with normal cooking events. The new technology is designed to trigger an alarm faster when synthetic smoke is detected than when smoke from cooking is detected, adding to safety and peace of mind.
