Reader/Keypad Troubleshooting
PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
The reader does not recognize
a card/tag (no beep, no LED
flash).
1. One or more of the readers’
wiring connections are incorrect.
Power down the reader/access panel and check that
your wiring is correct.
2. The reader is not receiving proper
power from the access panel.
Measure the voltage at the reader. It should be
b5 VDC and +14 VDC.
3. The reader is mounted too close
to a device that radiates
electromagnetic interference.
If possible, install the reader in a different location or
move any other electronic devices away from the
reader.
4. You are using an incorrect type of
card.
Make sure you are using an access card that is
compatible with the reader.
The reader has a short read
range.
1. The connection of the reader's
shield wire has opened somewhere.
Check the shield line for open connections. Make
sure it is properly connected to the access panel.
2. The reader is mounted too close
to a device that radiates electro-
magnetic interference.
If possible, install the reader in a different location or
move any other electronic devices away from the
reader.
3. The power supply is generating
electromagnetic interference.
The power supply on the access panel must be a
regulated, linear supply. Switching supplies are often
sources of electromagnetic interference.
