LED & Alarm Status Guide
Green LED blinks slowly. The detector is powered and monitoring CO levels normally. No CO detected above safe threshold.
Yellow LED blinks rapidly and the 70dB+ voice alarm activates. CO concentration has exceeded 250ppm. Evacuate immediately and ventilate the space.
Low battery warning alarm sounds. Replace the CR123A lithium battery immediately to ensure continued protection.
Why CO Detection Matters
Carbon Monoxide is colorless, odorless, and tasteless - impossible to detect without a sensor. It is produced by gas heaters, boilers, and engines. Even brief exposure to high concentrations can be fatal.
