The Fireangel FA3820 carbon monoxide detector detects the presence of CO and alerts you with a siren and visual indicators. Its electrochemical sensor detects low levels of CO and activates high-sensitivity mode when needed.
The ventilation warning alerts you when the area needs to be ventilated, while the memory function uses a red LED to indicate previous alarm activations. Test mode reduces the alarm volume during testing, and Sleep Easy mode disables low-battery alerts for up to 8 hours. The wired connection enables detailed diagnostic checks.
