【Dual Sensor Keep Your Safety】: The combination smoke and CO detector detects both smoke and carbon monoxide faster and more accurately using a photoelectric smoke sensor and an electrochemical CO sensor, protecting your home from two potentially deadly threats.
【LCD Digital Displays】: The informative LCD will show you the battery level and real-time CO levels in PPM (parts per million). If there is fire and carbon monoxide with a concentration over 0.1% db/m, the blue light flashes rapidly. If CO is detected, the red light will flash. When under normal standby, the LCD will not display the CO concentration, and the green light will flash one time every 35 seconds. That means the carbon monoxide and smoke detector is working properly.
【Battery-Operated&Easy Installation】: This CO alarm is powered by 3x1.5V AA batteries (not included). Easy to mount this combo Smoke and Carbon Monoxide Detector with the included mounting bracket, screws, and anchor plugs.
【Test Mode Button and Loud Alarm】: It allows you to easily know the working status of the smoke detector and carbon monoxide detector. You can press the test button to inspect the alarm weekly. Alarm Volume: Loud>85dB at 3 meters. The loud 85-decibel alarm is designed to be heard easily.
