• 【Real-Time LCD Display & 360° Airflow Design】 The easy-to-read LCD screen shows real-time carbon monoxide levels (in PPM) and battery status at a glance. Smart LED indicators provide visual alerts—red for CO detection and blue for smoke—while multi-directional sensing holes help minimize false alarms and detect hazards quickly from all angles.
• 【10-Year Battery Life & Hassle-Free Installation】 Equipped with a powerful built-in 10-year lithium battery, this alarm requires no wiring or frequent battery changes. Simply mount it with the included bracket, screws, and anchors in minutes. Enjoy reliable, maintenance-free protection with lifetime free replacement support from Kesymo.
