Brand: KLTsenaife

Features:

• Upgraded Dual Sensors with 10-Year Lifespan：Built with advanced photoelectric smoke and electrochemical carbon monoxide sensors, this 2-in-1 smoke and CO detector delivers faster, more accurate alerts against two deadly household threats. Unlike standard 3-year sensors, our professional-grade sensors last up to 10 years for long-term home safety.
• Real-Time LCD Display & Airflow-Guided Multi-Directional Detection： The large LCD screen shows real-time CO levels in PPM and battery status at a glance. Smart LED indicators provide instant visual alerts—red for carbon monoxide, blue for smoke—while the spiral airflow-guiding housing draws air in from multiple directions toward the sensor chamber for faster, more stable detection and fewer false alarms.
• 10-Year Sealed Battery – No Replacement Needed：Powered by a built-in 10-year lithium battery, this smoke and carbon monoxide alarm eliminates low-battery chirping and frequent replacements. No wiring required—simply mount it with the included bracket and hardware for reliable, maintenance-free protection—backed by dedicated lifetime customer support for complete peace of mind.
• One-Button Test & 85dB Loud Alarm：Test or silence the alarm with one simple press. The powerful 85dB siren is loud enough to wake sleeping family members and alert everyone in the home. A temporary silent mode helps mute nuisance alarms while maintaining safety monitoring.
• SGS Tested to UL217 & UL2034 – Global Laboratory-Verified Safety： This smoke and carbon monoxide detector is tested to UL217 and UL2034 standards by SGS, one of the world’s most respected, ILAC ISO 17025 & NRTL-accredited laboratories. This means the performance, accuracy, and reliability of every unit is independently verified to the same strict standards used by leading global safety brands—so you can trust it to protect what matters most.
