2GIG-SMKT100-345 Product Description:


The 2GIG-SMKT100-345 is a multi-function wireless smoke, heat, and freeze detector engineered to provide comprehensive life safety protection for residential and commercial environments. Designed to detect potential fire issues earlier and with greater accuracy, this intelligent device ensures timely alerts in the event of smoke, excessive heat, or freezing conditions.

Using advanced detection algorithms and a sophisticated photoelectric optical sensor, the SMKT100-345 distinguishes real fire and smoke events from everyday activities like cooking, significantly reducing nuisance alarms. It meets the rigorous UL217 8th Edition and UL268 7th Edition standards, ensuring high-performance detection of smoke from both natural and synthetic materials commonly found in modern furnishings.

Part of the 2GIG 345S Series, the detector features an onboard switch for encrypted or non-encrypted communication, simplifying installation and inventory management for professional installers. It seamlessly integrates with 2GIG EDGE, GC Touch, and earlier 2GIG control panels, providing reliable compatibility across the 2GIG ecosystem.

In addition to smoke detection, the SMKT100-345 offers multi-level temperature monitoring, including a fixed high-heat alert at 134°F, a freeze alert at 40°F, and a rate-of-rise detection function for rapid temperature increases. With a projected 10-year battery life, the device delivers long-term reliability, reduced maintenance, and consistent protection.
