5.3 Audio Line Fault
5.3.1 Speaker Line Fault/Amp Fault
• Check EOL resistor (56k)
• If ok, swap speaker lines to a different Zone (on amp)
Test to see if the fault has followed
• IF YES – the fault could be in the field (wiring, devices)
• IF NO – the fault is likely to be in the transformers/amplifiers
NOTE:
A good way to test where a fault is located within the panel is swapping identical
components over and testing to see if the fault follows the device. This allows you to
eliminate if the fault is located on a device/card within the panel or out in the field
wiring/devices.
5.3.2 Amplifier LED Configurations
The red LEDs on the HAMP9308 and AMP 200 indicate that the speaker load is greater than
the amplifier’s rating, or the output is short circuited, and the amplifier has briefly switched off
to prevent damage. Both LEDs of the HAMP9308 will operate in unison in 1 * 100W mode and
the LEDs on both amplifier modules will operate in unison on the AMP200.
