System Sensor SpectrAlert Advance (series)

The SpectrAlert Advanced series is a series of notification appliances manufactured by System Sensor. They are selectable-output notification appliances, and plug in designs. The series was introduced in 2006, but most of the series was discontinued in 2017 in favor of the new L-series that year, but the weatherproof models of the SpectrAlert Advanced series are still being produced today. The horns and horn/strobes are well-known for their extremely loud sound, up to a whopping 101 dB max!
