This is a great part 2 in 1 - Carbon Monoxide and Smoke Alarm. built-in intelligent chipset. I see that the Photoelectric Smoke Detector and Electrochemical CO Detector with Real-time Intelligent Monitoring System are UL 217 and UL 2034 standards, which ensures the highest level of safety and reliability, and it's good to know. 1 combination smoke and smoke detector is accurate and reliable, suitable for home, bedroom, living room, garage, hotel, indoor, vehicle, factory. I also liked the LCD display, the LCD digit shows the concentration of carbon monoxide (CO) in real time. ambient air and battery level. A low battery warning ("LB") lets you know it's time to replace the battery; The smoke alert ("HHH”) alerts you that a smoke fire is occurring. It has three alert modes: 85dB buzzer, LED, and human voice alert, which is really cool. A loud 85dB buzzer with a rapidly flashing red indicator light alerts you when dangerous levels of smoke or CO are detected. The carbon monoxide smoke detector will give clear human voice warning to warn children and old people to avoid danger. It has a lot of features which is why I give it 5 stars and it's been great so far. - Check the system, the system checks the sensors in real time, the green light indicates correct operation; The yellow light of device failure can show you the working status clearly. Overall I'm very happy with it.
