First Alert Z-Wave Plus Battery-Powered Photoelectric Smoke and Carbon Monoxide Detector w/Wi-Fi

The First Alert Battery-Powered Combination Smoke and Carbon Monoxide Alarm features voice and location technology and has the ability to wirelessly interconnect with other compatiable alarms. Interconnect muliple alarms throughout the home to create a safety network so when one sounds, all connected alarms sound to help provide an early warning. No rewiring is required to install. The voice and location alerts will also tell you the type and location of danger in the home when detected. This 2-in-1 alarm detects both smoke and carbon monoxide using a photoelectric smoke sensor and electrochemical carbon monoxide sensor. A low battery chirp will let you know when the batteries need to be replaced, and a one-touch button allows you to easily test and silence false alarms.
