EA120 au

The Pertronic EA120 amplifier is a high performance amplifier for the Pertronic F220 fire alarm system.

With excellent sound clarity, this amplifier is suitable for all non-emergency and emergency applications including occupant warning, public address, and background music.

The on-board keyboard and LCD display provide speaker load measurement and other menu-driven test and management features, together with user-friendly configuration of operating settings, announcements, and signals. Configuration files can be saved and loaded via USB, allowing a single configuration file to be copied to multiple amplifiers.

The built-in audible signal generator produces signals and announcements for many purposes including the evacuation and alert signals specified in AS 4428.16. Additional signals including custom voice messages are easily added via USB.

The Pertronic EA120 features three audio inputs suitable for local and/or remote microphones and external audio sources including background music.

With a large number of easily configurable options, the Pertronic EA120 satisfies a wide range of audio system requirements.
