Problem Solution
The control panel does not power up.
• Check setting of JP1 on middle board (near input power connector) to ensure that the
jumper is in the appropriate position for your desired power source.
• Measure input power for +12VDC
• If RED LED’s are off, then input fuse may be blown. This fuse is not field-replaceable.
The control panel powers up but does not
respond to card readers or inputs.
• Measure power at reader connectors. If no voltage is present, then reader fuse may be blown.
• Bring reader and/or input and connect directly at the panel. If it works at the panel, the
wire run may be faulty.
No network communication exists with
the control panel.
• If LAN LED’s are off or solid, then no physical network connection exists. Check network cabling.
• Verify the Subnet Mask, Gateway, DNS and IP address as provided by the network admin.
How to reboot the system? • Hardware Reboot system: Momentarily press switch S2 on middle board (near bank of 16 LED’s).
How to clear the memory of the system
and restore factory defaults?
