Top 9 Best Personal Co Fire Detector

✔[High sensitivity] The upgraded photoelectric and electrochemical sensors significantly improve alarm sensitivity, thus speeding up response time while minimizing false positives. The device can be quickly and easily installed without electrician, making your life easier.
✔[10 years product life] Smoke and carbon monoxide alarms feature two replaceable AA batteries and an end of life signal that lets you know when you need to change equipment to ensure safety. Longer product life, so that the family safety up to ten years.
✔[2 in 1 Protection] The combined smoke and carbon monoxide detector is equipped with an electro-optical smoke sensor and an electrochemical CO sensor that operate independently of each other. It detects both smoke and co, making your home safer by providing the ultimate protection against two deadly threats.

✔Longer Service Life - Keeps your home safe for up to 10 years. 2 replaceable AA batteries last 3 times longer than 9V batteries. When the combination detector is at the end of its life, an end-of-life signal will let you know when it's time to replace it.
✔Unique Voice Speaker - Unique smoke detector and CO detector alarms distinguish between smoke alarms and CO warnings. Co alarm: "Warning, carbon monoxide, evacuate! Smoke alarm: "Fire!" . Verbal warning system reduces confusion and helps people maintain order.

✔This device only measures 5 × 1.4 in (128 × 34.7 mm) and comes in a thin and light design; with the accessories included, it is easy to install, without the need to hire an electrician
✔This battery-powered combination smoke and carbon monoxide alarm uses both photoelectric and electrochemical sensors to protect you and your loved ones against smoke and dangerous CO levels, keeping your home and family safe for a decade
