Wireless Interconnect Battery Operated Carbon Monoxide Alarm w/ Voice Location

The First Alert CO511B Wireless Interconnected Carbon Monoxide Alarm with Voice and Location detects elevated carbon monoxide levels and can work with compatible models to create a wireless alert system throughout your home. This wireless-enabled battery-operated detector alerts you by using audible signals including a loud 85-decibel siren and that studies have shown to wake up children better than standard alarms. Wireless Interconnected technology allows other compatible First Alert wireless-enabled alarms located in separate areas of your home to communicate with each other, alerting you to a problem even when it's on another floor. The carbon monoxide alarm features a sensor for increased accuracy.

Can Be Connected with Compatible Alarms for Enhanced Safety

The First Alert CO511B Carbon Monoxide Detector can be connected with multiple alarms around your home or office (a maximum of 12 smoke alarms and 6 carbon monoxide alarms) to create a safety network of detection (additional alarms sold separately). Compatible wireless alarms can communicate with each other through a radio frequency, so when one alarm sounds, all of them sound. The communication distance (range) between any two First Alert Wireless Interconnect Alarms is typically 50 ft. (15 meters) inside of a home. Some features of a home, such as the number of floors, number/size of rooms, furniture and types of building materials used may reduce the range of wireless interconnect alarms. Earlier notification of danger means you can avoid dangerous CO levels sooner.

Battery-Operated Alarm Installs Easily

The battery-operated wireless interconnected carbon monoxide detector requires no wiring and no electrician to install. Simply put two AA batteries into the detector and mount it on any wall or ceiling. A low-battery light and chirp will let you know when the batteries need to be replaced. A one-touch button silences false alarms and allows you to test the CO detector for functionality.

Accurate Detection Technology

This carbon monoxide alarm uses an advanced electrochemical sensor to detect carbon monoxide leaks from multiple sources, including faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes. The voice alarm as well as indicator lights on the front of the detector identify both the threat and its location. Studies have shown that children wake up better to voice alarms than standard alarms.

Carbon Monoxide and Smoke detectors

Easy to understand and program, loud enough to wake up the whole house up and perfect for anyone who doesn't want to or who can't hard wire these devices. One goes off and they all talk to each other to let you know what level the problem in on. Well worth it.
