The System Sensor FAAST (Fire Alarm Aspiration Sensing Technology) detector with five alarm levels provides advanced warning of smoke while virtually eliminating false alarms. Its exclusive dual source sensing technology uses a highly sensitive blue LED to sense smoke, while an infrared laser quickly distinguishes other airborne particulates from smoke. The detector interprets signals from both sources to warn of smoke up to 60 minutes prior to combustion. An integrated communications package unique to FAAST can provide e-mail notifications of specific alarm levels, fault levels, and other isolated conditions to multiple e-mail addresses.
