First Alert CO400 Carbon Monoxide Detector, Battery Operated, 2 Pack

This 2-pack of FIRST ALERT CO400 Carbon Monoxide Alarms utilizes advanced electrochemical carbon monoxide sensors to continuously monitor your living space for carbon monoxide threats. Powered by a replaceable 9-volt battery, these battery-operated detectors do not require any professional installation - simply insert the battery, and the alarms are ready to go. The electrochemical CO sensors are designed to detect carbon monoxide leaks from various sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running indoors or too close to the home.

When CO levels become dangerously elevated, the alarms will sound a loud 85-decibel alert to warn you of the threat. Since carbon monoxide evenly distributes itself, it is crucial to have a CO detector on every level and in each bedroom of your home to ensure complete protection. Featuring a simple one-button design, these detectors allow you to easily test the unit's functionality or silence the alarm as needed. An end-of-life timer also lets you know when it's time to replace the device.

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in the United States, yet many people are unaware they are suffering from CO poisoning until it's too late. With symptoms resembling the flu, you may not even realize you are in danger initially. This is why a reliable carbon monoxide alarm, like the FIRST ALERT CO400-3, is an excellent way to safeguard your family. These alarms can detect the colorless, odorless CO that you cannot see, smell, or taste in the air.

Utilizing the most accurate electrochemical carbon monoxide sensor technology available, the FIRST ALERT CO400-3 alarm provides long-lasting, permanent monitoring. Powered by a replaceable 9V battery, the unit can continue operating even during power outages, giving you peace of mind. The test/silence button allows you to conveniently check the alarm's functionality or temporarily hush the siren if needed. Should CO levels persist, the alarm will sound again, with the loud 85-decibel horn alerting you to the ongoing threat.

No installation is required for these alarms, and the attractive design enables you to place them anywhere they are needed, with an optional wall mount available. An audible and visual low battery indicator will let you know when it's time to replace the power source. The unit also includes a pull-down action chart providing instructions on what to do if the alarm is triggered. Backed by a 5-year limited warranty and UL-listed for safety, these FIRST ALERT CO400-3 carbon monoxide alarms are compliant with current regulations in California, Wisconsin, and Oregon.

Keep your family safe with this 2-pack of easy-to-use, battery-operated carbon monoxide detectors. The continuous monitoring provided by these alarms will give you the peace of mind of knowing your home is protected, even during power outages.
