Smoke and Carbon Monoxide Detector for Home and Kitchen

The Smoke Detector Carbon Monoxide Detector Combo offers 2-in-1 protection, utilizing a highly sensitive photoelectric sensor to detect smoke and a stable electrochemical CO sensor to detect carbon monoxide. Once smoke or carbon monoxide reaches the alarm sensitivity level, both a loud sound alarm and LED indication will be triggered to alert you and prompt immediate action.

Unlike constant-display models, this smoke and carbon monoxide detector's LCD screen remains blank in standby mode to conserve battery life. The display will show readings only when the batteries are installed, the test button is pressed, or dangerous levels are detected. This non-intrusive design ensures the device does not disturb you during sleep.

The large LCD display provides real-time monitoring of both smoke and CO concentrations, allowing you to stay informed about the air quality in your surroundings. The display can also signal if the carbon monoxide detector is malfunctioning, keeping you aware of the alarm's working status.

The test button serves to verify the battery and alarm operation, ensuring the smoke and carbon monoxide detector is functioning properly. The loud 85dB+ alarm speaker ensures you can clearly hear the warning in the event of an emergency.

Installation is simple - twist the mounting bracket clockwise to remove it from the back of the device, drill two 5mm holes in the ceiling or wall, insert the plastic plugs, and secure the bracket with the provided screws. Insert a fully charged battery, then match the key holes and twist the device anti-clockwise to lock it in place.

The 360-degree air holes allow the smoke alarm to detect smoke or carbon monoxide from all around, providing comprehensive safety coverage.

The green LED indicates a successful test of the smoke detector's electronics when the test button is pressed. If the device emits a chirp every 30 seconds with the green LED off or displays "Err" on the LCD, it signals a malfunction.

The red LED will flash, and the alarm will beep simultaneously, during a CO alarm, fire alarm, or low battery mode.

To reset the device, first remove the batteries, then press the test button several times to discharge any excess electricity. Next, press and hold the test button while reinstalling the batteries until the LED flashes, then release. If resetting does not resolve the issue, please contact the manufacturer for assistance.

This smoke and carbon monoxide detector offers dual sensor protection, providing a comprehensive safety solution for any home or office environment. With its real-time monitoring, loud alarm, and easy installation, it ensures reliable detection and notification of potential threats at all times.
