8 Channel Amplifier Fault Changeover with Speaker Line Surveillance                               

ACS-800                                                                               


Description:

The 8 channel amplifier fault auto-changeover with speaker line impedance surveillance is an integrated controller integrates the amplifier fault changeover with the speaker line surveillance into one 19” 1U unit. The amplifier fault auto changeover will automatically switch into standby amplifier once there is anyone of the 8 amplifiers in case of fault. The switching time is within 1 second. The speaker line impedance supervision enables to supervise the speaker line open circuit, short circuit and impedance fluctuation. Each zone detection time is within 2 seconds, The amplifier fault and speaker line fault will be reminded by front panel visualized indicator, buzzer and fault contact or RS485 contact to third party system.

The amplifier fault changeover and speaker line surveillance unit is design with full visual indication. There are 8 amplifier working status indicators, green of normal, yellow of standby and red of fault and distinguished of non-used. There are 8 speaker line monitoring status indicators, green of normal, yellow of standby and red of fault and distinguished of non-used.

There are 8 line inputs 8 line outputs with 24V overriding relay, 8 amplifier inputs of 100V and 8 zone 100V outputs. One fault output, one RS485 output to inter-work with third party system. Dipswitch for 8 zone enable or disable the monitoring. Auto & manual two operation modes. One calibrate button on front panel to initialize or calibrate each amplifier and speaker line setting. Speaker line impedance surveillance have 10% and 20% fluctuation two options. Expandable from 8 zones to max 192 zones. 24V DC operation system.
