The 2GIG SMKT8E-345 stands as a premier eSeries life safety solution, offering encrypted, multi-faceted protection against smoke, heat, and freezing conditions within a single, highly reliable wireless device. Its sophisticated optical smoke detection chamber utilizes advanced photoelectric technology to accurately identify a wide range of fire types, from slow smoldering to fast flaming, while intelligently reducing common nuisance alarms often triggered by cooking or steam, ensuring alerts are both prompt and precise. Comprehensive fire detection is further enhanced by dual heat sensing capabilities, which trigger an alarm upon detecting a rapid rate-of-rise in temperature—a key indicator of a quickly developing fire—or when a critical fixed high-temperature threshold is exceeded, providing an additional layer of responsiveness. Beyond fire threats, the SMKT8E-345 includes an invaluable freeze detection feature, alerting homeowners to dangerously low temperatures that could lead to frozen pipes and significant water damage, offering crucial preventative warnings.Engineered for long-term dependability, this fully supervised detector boasts a 10-year product life, including its sealed-in lithium battery, eliminating the need for frequent battery changes and reducing maintenance for homeowners. It is ETL listed and meets the rigorous UL217 and UL268 standards for smoke and heat alarms, respectively. Designed for seamless integration with 2GIG eSeries security panels (such as GC2e, GC3e, and Edge), its encrypted 345 MHz communication ensures secure and tamper-resistant signaling, offering both installers a trusted, code-compliant device and homeowners superior security and peace of mind.
