Nortek Releases New 2GIG Smoke/Heat/Freeze Detectors

The new detectors feature updated optical sensors and detection algorithms, including encryption technology for more secure communication with 2GIG eSeries security panels.

CARLSBAD, Calif. — Nortek Security & Control recently introduced two new 2GIG smoke/heat/freeze detectors it says are 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, according to the company.

“With synthetic materials so common in today’s homes, faster detection is essential,” says 2GIG Product Line Manager Susan Lin. “These new sensors have been designed to detect fire issues earlier, providing greater safety in the event of a fire, while also reducing the amount of cooking-related nuisance alarms that often cause homeowners to disable their smoke detectors.”

While traditional smoke detectors identify smoke and trigger an alarm when the smoke density has reached a specific level, the new 2GIG smoke/heat/freeze 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, according to the company.

This results in the alarm triggering faster if smoke from common synthetics is detected, which tend to burn faster.

“The new 2GIG smoke/heat/freeze detectors respond to the dangers posed by faster-burning synthetic materials,” Lin says. “They meet the new UL217 8th Edition standard by increasing responsiveness to the presence of smoldering and burning synthetic materials while decreasing nuisance alarms.”

The 2GIG smoke/heat/freeze detectors also 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°F.

A rate-of-rise temperature alert is sent to the panel and siren is triggered when ambient temperature is at 104°F and rises 15°F or more in one minute, and a freeze warning is sent to the panel if the ambient temperature is below 40°F for more than one minute.
