Secure Your Home with Essential CO Protection
First Alert CO400 battery-operated carbon monoxide alarms provide essential home safety for Indian households. This 6-pack features advanced electrochemical sensors that accurately detect CO leaks from appliances, blocked chimneys, or generators. The battery-powered design ensures continuous monitoring, even during power failures, offering peace of mind across every level and bedroom of your home.
When CO levels reach dangerous thresholds, a loud 85-decibel alarm sounds to alert you. Each unit is designed for simplicity with a single button for testing or silencing, and an end-of-life timer indicates when replacement is needed. The included 9-volt batteries mean they are ready to install right out of the box.
Unlike local alternatives that may rely on mains power, these battery-operated units are ideal for India's variable power supply. Imported directly, all customs duties and GST are included in the listed price, with tracked delivery via ExpressBox.
Reliable Safety for Indian Homes
First Alert CO400 alarms offer dependable carbon monoxide detection, vital for Indian households using gas appliances, generators, or in areas prone to poor ventilation.

Electrochemical sensors provide accurate readings, and the loud 85-decibel alarm ensures everyone is alerted to danger. Easy to install and maintain, these units are designed for continuous monitoring, providing essential safety across every floor and bedroom.

Who It's For vs. Who Should Skip It
Ideal for homeowners, renters, and families in India seeking reliable, battery-operated carbon monoxide detection. Perfect for placement near sleeping areas, kitchens with gas appliances, or rooms with generators.
