Wireless Interconnected Carbon Monoxide Alarm is designed to continuously monitor carbon monoxide concentration. Adopting advanced electrical technology, a built-in high-volume buzzer, it responds quickly and becomes highly sensitive with stable performance and low false alarm. 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.
