Specifically designed to continuously monitor smoke concentration, it responds quickly and becomes highly sensitive with stable performance and low false alarm. Once the surrounding smoke concentration reaches the alarm value, it promptly sends out visual and audible alarm signal to alert the user of the danger. The smoke alarm can be interconnected via a hardwired or wireless system (using optional WisuLink wireless interconnected module). Once one device triggers an alarm, the signal will be pushed to every alarm in the interconnected network and they will raise the warning in unison.
