Combination Smoke and Carbon Monoxide Detector with LCD Display, Alarms, Replaceable AA Battery Included, CO Alarm, Test/Silence Button, Pack of 2

Easy to install: Supplied with mounting screws and wall plugs, it's easy to install on the wall or ceiling without the need for wiring or a technician. The battery-operated smoke/CO detector ensures it will work even during a power outage. Compact and reliable: The smoke and carbon monoxide detector is compact, stylish, and lightweight, making it easy to install. A Test/Silence button allows you to test it weekly, and when a non-emergency situation (false alarm) occurs, simply press the Test button to silence the harmful alarm while the LED light continues to flash to indicate that it is in silent mode. Replaceable battery operation: The device comes with two high-capacity AA alkaline batteries, which last for more than three years. The detector will keep you safe at all times with built-in low-battery warning features that remind you to change the batteries with a continuous beep every 40 seconds and a flashing yellow light when the battery capacity is low. 2-in-1 Protection: This combination smoke and CO detector features two sensors that quickly detect fire smoke hazards and/or carbon monoxide leaks in a single device, instantly alerting you with an 85 dB audible alarm and a flashing visual LED light. Easy-to-Read LCD Screen: The LCD screen displays real-time CO concentration levels above 20 ppm (parts per million). If a dangerous carbon monoxide leak is detected, the red CO indicator flashes rapidly. If fire smoke is detected, the red smoke indicator flashes. In standby mode, with no alarm, the LCD screen displays 0 ppm and the green light flashes every 40 seconds to indicate that the device is functioning correctly. CO is a highly toxic gas that has no taste, color, or odor. It usually comes from faulty combustion appliances or blocked flues.
