VA-P8500S 8 Zone Voice Alarm Amplifier


    • Support the speaker loop grounding, open circuit and short circuit detection.
    • Support the speaker loop cabling of 3 or 4 wire.
    • 8 Programmable trigger input interfaces.
    • 8 Programmable trigger output interfaces.
    • Support power amplifier enter power saving mode to save energy when no signal input.
    • Support the line redundant cabling.
    • Support linkage with fire alarm control unit to realize fire alarm linkage control.

    Basic Functions:

  • * Built-in 500W digital amplifier and 8 power zone outputs, each zone has independent LED indicator, output control button and volume control.
  • * With Network input, EVAC input, BGM input, local emergency mic input, mic input and 2 line inputs; user can set the priority of audio output through the VA-6000ST.
  • * It can work with an external backup amplifier, when the built-in amplifier has faulted, it can automatically switch to backup amplifier.
  • * Automatic real-time monitor the operation of each zone speaker loop (Ground connection, open circuit, short circuit).
  • * With 8 channels *dry contact* input interfaces, can trigger pre-program edited voice messages to the designated zone or open the corresponding external power supply to achieve the corresponding event warning.
  • * With 8 channels programmable relay signal output interfaces, can output short circuit no voltage control signal to the third party device to realize online automatic control.
  • * Support 24V DC input interface (External connect with the 24V DC supplied by VA-6000BC)Specification:
