Upgraded Smoke and Carbon Monoxide Alarm Detector (2-Pack)

This smoke and carbon monoxide detector comes equipped with three distinct standby modes to ensure your safety. The green light flashes once every 35 seconds, indicating a normal standby situation. If the unit detects smoke concentration exceeding 0.1% db/m, the blue light will flash rapidly, and the buzzer will sound a continuous alarm. Additionally, a low battery warning is signaled by a red light flashing once every 20 seconds, accompanied by an "Lb" display on the LCD.

Powered by three 1.5V AA batteries, this alarm boasts a long lifespan, durability, and safety. You'll receive both audible and visual alerts when it's time to replace the battery. Compared to other alarms that come with their own batteries, this model is more convenient and safer, as it utilizes a standard battery type, unlike potentially troublesome lithium battery alarms.

The combination smoke and CO detector employs a photoelectric smoke sensor and an electrochemical CO sensor to detect both smoke and carbon monoxide more quickly and accurately. When the alarm detects harmful gases, it will emit a loud warning sound to alert you of the danger. Additionally, the alarm will remind you to replace the battery when the power level is low.

Whether you need 1, 2, 3, or 6 carbon monoxide detectors/smoke alarms, we've got you covered. All options feature the same reliable detection capabilities, with the 1-pack, 2-pack, 3-pack, and 6-pack configurations available to suit your specific needs.

With a 4.3-out-of-5-star customer rating based on 246 reviews, this product has consistently delivered excellent performance. All models detect both smoke and carbon monoxide, utilizing photoelectric and electrochemical sensors, and include low battery warnings, loud alarms, LED indicators, and LCD displays.

Compared to most carbon monoxide smoke detectors on the market, which typically have a three-year sensor lifespan, this upgraded version boasts a remarkable 10-year sensor lifespan, ensuring a longer service life for your home safety solution.

The informative LCD displays the battery level and real-time CO levels in parts per million (PPM). If there is a fire or carbon monoxide concentration exceeds 0.1% db/m, the blue light will flash rapidly. The red light will flash if CO is detected. Dense gas-sensing holes prevent false alarms, giving you greater peace of mind.

This CO alarm is battery-operated, powered by 3x1.5V AA batteries (not included), and easy to install using the included mounting bracket, screws, and anchor plugs. The test mode button allows you to quickly check the working status of the smoke and carbon monoxide detectors. With a loud 85-decibel alarm designed to be heard easily, you can also enter a silent mode to address any non-emergency situations.
