GT High Performance 10 year sealed lithium battery wireless interconnected carbon monoxide alarm

You never need to change the battery and no electrician required for installation! The GT Wireless Interconnected Carbon Monoxide Alarm is designed to continuously monitor carbon monoxide concentration. Adopting advanced technology, a built-in high-volume buzzer, it responds quickly and becomes highly sensitive with stable performance and low false alarms. Once the surrounding CO concentration reaches the alarm value, it will promptly send out an audible and visual alarm signal to remind the user to take immediate measures. Moreover, the alarm signal will be pushed to every alarm in the interconnected network and they will raise the alarm in unison.
