2GIG SMKT8 and SMKT8e Smoke/Heat/Freeze Sensor - Data Sheet
Smoke Heat Freeze Detector
2GIG-SMKT8E-345 (eSeries with encrypted signal)
2GIG-SMKT8-345 (non-encrypted signal)
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*.

The new 2GIG Smoke Heat Freeze Detector has been designed to detect fire issues
earlier, providing a more accurate and timely notice in the event of smoke or fire.
• Meets new UL217 8
• Designed to recognize smoke from
some synthetic materials.
• Monitors and reports on excessive
• Optical smoke detection chamber for
improved smoke detection.
• Rate of Rise alert is sent to the panel and
a siren is triggered once the room temperature
F and the temperature rises 15 degrees
or more in one minute.
• Extreme high/low temperature alerts.
• Long-lasting battery with projected life
of 10 years.
• 2-year product warranty.

Specification and availability subject to change without notice
Traditional smoke detectors trigger an alarm when any smoke density reached a specific level, which could
have just been normal cooking events. The 2GIG 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.
The new technology is designed to trigger an alarm faster when synthetic smoke is detected versus
smoke from cooking, adding to safety and peace of mind.
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).
