TROUBLESHOOTING PROCEDURES:
Figure 9 Power and trouble LED's on the SP4Z-A/B Splitter PC board.
1.
Insure that the green POWER LED is “ON”. If no LED's are lighted, check the 24VDC input power.
2.
Verify wiring is correct.
3.
Verify jumpers are correct.
4.
If the yellow TROUBLE LED is “ON” an output circuit supervision trouble is indicated. Remove the SP4Z-A/B cover and observe the 8 yellow LED's as shown
in Figure 9 to determine the reason for the trouble.
5.
For each SHORT LED “ON”, check the speaker output wiring for that zone for a short or a faulty speaker appliance.
6.
For each OPEN LED “ON”, check the speaker wire run for that zone for an open or that the end of line resistor is missing. With the zone wiring removed from the
SP4Z-A/B, a resistance reading on the zone will indicate the 10K Ohm EOLR and the wire resistance if the circuit is correct.
7.
If a zone output does not operate and the green POWER LED is “ON" while the yellow TROUBLE LED is “OFF”, the SP4Z-A/B splitter has malfunctioned.
Replace.
