The Amplifier Terminal Panel is a 19 in rack mount device that interfaces the Audio Power Amplifiers to the 2-AAC. The Amplifier Terminal Panel monitors primary AC power to Audio power amplifiers. If the amplifiers are active and primary power fails, the ATP transfers the amplifiers to battery power. The ATP contains a battery charger capable of charging 40 AH batteries. The ATP contains terminals to connect preamp signals from the 2-AAC to the power amplifier for connection of the power amplifier output. The ATP is the originating point for the audio power risers. The front panel of the ATP contains a green power LED, amber trouble LED and an amber trouble silenced LED. A momentary switch is available on the front panel for trouble silence. The ATP provides a battery saver feature that applies battery power to the amplifiers only when two conditions are met; low or no AC power and a Fire Alarm or page request. This feature may reduce the battery size requirements by a factor of 8.
