Reader/Keypad Troubleshooting

PROBLEM
The reader does not recognize
a card/tag (no beep, no LED
flash).
The reader has a short read
range.
POSSIBLE CAUSE
1. One or more of the readers'
wiring connections are incorrect.
2. The reader is not receiving proper
power from the access panel.
3. The reader is mounted too close
to a device that radiates
electromagnetic interference.
4. You are using an incorrect type of
card.
1. The connection of the reader's
shield wire has opened somewhere.
2. The reader is mounted too close
to a device that radiates electro-
magnetic interference.
3. The power supply is generating
electromagnetic interference.

Installation Instructions
CORRECTIVE ACTION
Power down the reader/access panel and check that
your wiring is correct.
Measure the voltage at the reader. It should be
between +5 VDC and +14 VDC.
If possible, install the reader in a different location or
move any other electronic devices away from the
reader.
Make sure you are using an access card that is
compatible with the reader.
Check the shield line for open connections. Make
sure it is properly connected to the access panel.
If possible, install the reader in a different location or
move any other electronic devices away from the
reader.
The power supply on the access panel must be a
regulated, linear supply. Switching supplies are often
sources of electromagnetic interference.
