First Alert BRK CO511 Carbon Monoxide (CO) Detector Wireless Interconnected with Voice and Location
Description
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. Designed for those who want a comprehensive detection system without hiring an electrician, this battery-operated carbon monoxide detector is an ideal solution. Wireless technology interconnects the detector with other compatible First Alert wireless-enabled alarms (sold separately) in your home to create a unified safety network. The alarms communicate with each other to alert you when there is a problem across the house, in a different room, or on a different floor. The advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, including faulty fuel-burning appliances. This carbon monoxide detector features a voice alarm that studies have shown to wake up children better than standard alarms. It can be programmed to announce which part of the home is experiencing heightened CO levels
