Procedure I
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the AMP indicator on the SACM-4 module is on, an
amplifier trouble condition has occurred. An amplifier trouble condition may be caused by:
1.
Faulty internal wiring between the backplane module and the digital voice module.
2.
A faulty SACM-4 module.
3.
A faulty SADC module.
4.
A faulty backplane module.
Perform the following:
1.
Verify that the wiring between the backplane module and the digital voice module is intact.
2.
Replace the SACM-4 module.
3.
Replace the SADC module.
4.
Replace the backplane module.
Procedure J
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the AUDIO indicator on the SACM-4 module is on,
an audio output wiring trouble condition has occurred. An audio output wiring trouble condition may be caused by:
1.
Missing end-of-line resistor on the audio output.
2.
The audio output field wiring is open or shorted.
3.
A fuse on the SACM-4 module is blown.
4.
A faulty SACM-4 module.
5.
A faulty backplane module.
Perform the following:
1.
Verify that the end-of-line resistor is properly in place.
2.
Verify that the audio output field wiring is intact.
3.
Verify that all fuses on the SACM-4 module are intact.
4.
Replace the SACM-4 module.
5.
Replace the backplane.
Procedure K
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the STROBE indicator on the SACM-4 module is on,
a visual notification output wiring trouble condition has occurred. A visual notification output wiring trouble condition may be caused
by:
1.
Missing end-of-line resistor on the visual notification output.
2.
The visual notification output field wiring is open or shorted.
3.
A fuse on the SACM-4 module is blown.
4.
A faulty SACM-4 module.
5.
A faulty backplane module.
Perform the following:
1.
Verify that the end-of-line resistor is properly in place.
2.
Verify that the visual notification output field wiring is intact.
3.
Verify that all fuses on the SACM-4 module are intact.
4.
Replace the SACM-4 module.
5.
Replace the backplane module.
Procedure L
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the PWR indicator on the SACM-4 module is on, an
amplified speaker power output wiring trouble condition has occurred. An amplified speaker power output wiring trouble condition
may be caused by:
1.
Missing end-of-line resistor on the amplified speaker power output.
2.
The amplified speaker power output field wiring is open or shorted.
3.
A fuse on the SACM-4 module is blown.
4.
A faulty SACM-4 module.
5.
A faulty backplane module.
Perform the following:
1.
Verify that the end-of-line resistor is properly in place.
2.
Verify that the amplified speaker power output field wiring is intact.
3.
Verify that all fuses on the SACM-4 module are intact.
4.
Replace the SACM-4 module.
5.
Replace the backplane module.
