The First Alert Battery-Powered Carbon Monoxide Alarm is an easy to use CO detector that uses an electro-chemical carbon monoxide sensor, which is the most accurate technology available. It can detect the CO you can't see, smell or taste in the air. A single button tests alarm functions and mutes nuisance or non-emergency alarms. With battery backup, you will have peace of mind that the alarm will continue to work even during power outages. An audible and visual low battery signal alerts you to replace the battery. Its attractive, compact and pleasing design is ideal for placing in all visible location with no installation required. The easy loading front access battery door allows you to quickly and easily change 2 AA batteries. It’s backed with a 5-year limited warranty and meets UL standards and is code compliant.
However, the major concern faced with this unit is the battery door mechanism. The flimsy battery door is made of cheap plastic material. The plastic latch breaks off easily if closed without installing the batteries (No such warning is mentioned with the device) or sometimes the door did not close securely thus leading to malfunction of the device.
Overall, The First Alert CO400 battery powered carbon monoxide detector is a recommended, easy-to-install, user friendly device that combines advanced technology at reasonable price for maximum protection.
