Nortek Security & Control LLC has introduced two new 2GIG smoke/heat/freeze detectors designed to detect fire issues earlier and recognize smoke from common synthetic materials to decrease nuisance alarms from everyday cooking. Both detectors feature updated optical sensors and detection algorithms, with one adding encryption technology for more secure communication with the new 2GIG eSeries security panels. The detectors use advanced algorithms and a sophisticated optical chamber to recognize the difference between smoke particles created by synthetic materials and those resulting from normal cooking events. Thus, the alarm is triggered faster if smoke from common synthetics is detected. The detectors help monitor and report on excessive temperature and variations. A high temperature alert is sent to the panel and the siren is triggered when the ambient temperature exceeds 134 deg. F. A rate-of-rise temperature alert is sent to the panel and the siren is triggered when ambient temperature is at 104 deg. F and rises 15 deg. F or more in one minute, and a freeze warning is sent to the panel if the ambient temperature is below 40 deg. F for more than one minute.
