Fire and CO Detector Combo, 10-Year Battery, 5-Pack

This combination smoke and carbon monoxide (CO) detector features an easy-to-read LCD that displays real-time CO concentrations (30-999 ppm), remaining battery life, and the working status of the alarm, allowing you to quickly assess the situation. Equipped with dual integrated sensors and an intelligent chipset, the device accurately detects smoke and CO, providing the earliest possible warning while effectively minimizing false alarms.

The detector automatically checks its battery and sensors every 60 seconds to ensure proper functioning. It is designed for simple installation, requiring no rewiring and easily mounting on any ceiling or wall using the included mounting bracket, screws, and anchor plugs. Upon installation, the alarm activates automatically, delivering reliable dual protection against both smoke and carbon monoxide that you and your family can trust.

The detector's multi-colored LED indicator, coupled with audible beeps, flashes red, green, or yellow to communicate different working statuses. An isolating plate inside the unit helps smoke pass through the sensor evenly, increasing the alarm's sensitivity, while also being dust-proof to prevent contamination of the circuit board.

Powered by a 10-year built-in battery, this smoke and CO alarm provides a long-lasting, maintenance-free solution. The upgraded photoelectric and electrochemical sensors significantly increase the sensitivity of the alarm, resulting in a faster response time and minimizing false alarms. Constructed from heat-resistant, high-temperature resistant, and corrosion-resistant PC material, the detector is built to last.

For added convenience, the combination detector can communicate with each other, allowing for a coordinated alarm system throughout the home. The loud 85 dB alarm ensures that the warning is clearly heard, alerting you and your family to potential dangers promptly.

In summary, this advanced smoke and carbon monoxide detector combines an informative LCD, dual-sensor technology, self-check functionality, and simple installation to deliver reliable, 2-in-1 protection for your home and family. With its premium construction, long-lasting power source, and effective alarm system, this detector offers peace of mind and comprehensive safety against fire and CO risks.
