Guardian Telecom’s AS12 Automatic Amplifier Switch continuously monitors amplifier signals and automatically switches to a standby amplifier if one fails. Capable of monitoring four amplifiers simultaneously, the AS12 instantly detects faults, automatically switches to a stand-by and visually indicates amplifier status.

Clearly visible LED’s on the front panel indicate the status of each amplifier so any fault can be quickly identified and corrected. The AS12 also maintains historical visual indicators for tracking the amplifier failure.

As a part of an integrated industrial emergency/communications system, the AS12 ensures uninterrupted communication in the event of an amplifier failure.
