Madison Express DHI-HY-SA5MB, Mains Smoke Alarm (9V battery)

Mains Powered Smoke Alarm is specifically designed to continuously monitor smoke concentration. Adopting advanced split-spectrum photoelectric chamber and a built-in high-volume buzzer, it responds quickly and becomes highly sensitive with stable performance and low false alarm. Once the surrounding smoke concentration reaches the alarm value, it will promptly send out visual and audible alarm signal to remind the user to take immediate measures. Smoke alarm can be interconnected via a hardwired or wireless system (using optional WisuLink wireless interconnected module). Once one device triggers an alarm, the alarm signal will be pushed to every alarm in the interconnected network and they will raise the alarm in unison.

• Hardwire interconnection up to 24 units
• Wireless interconnected with maximum of 24 devices, compatible with WisuLink wireless interconnected module
