Troubleshooting

System start up takes about 60 seconds. Blue LEDs DL1 to DL16 light during boot.

Panel does not power up

Check jumper JP1 is set for the power source you use (PoE or external 12 VDC).
Measure for 12 VDC at the input. If the red LEDs stay off, the input fuse may be blown. It is not field replaceable.

Panel powers up but readers do not respond

Measure power at the reader connectors. No voltage points to a blown reader fuse.
Connect the reader directly at the panel. If it works there, check the wire run.
