The 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 photo-electric 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 provides increased performance and better detection of smoke, 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).
