1. High sensitivity and fast response: The built-in carbon monoxide detection chip and electrochemical sensor are enough to detect the invisible deadly carbon monoxide in the air, and respond quickly in the event of a fire, saving your life at the first time.

2. Carbon Monoxide Alarm: This is a state-of-the-art carbon monoxide alarm designed to provide early warning of the presence of carbon monoxide. It features an electrochemical carbon monoxide sensor, 85dB horn, fully functional test switch and red LED light to indicate DC power or alarm.

3. Alert warning: When a dangerous level of carbon monoxide is detected, the red LED will flash and a loud alarm pattern will sound – 85 dB alarm with LED flashing.
