Problem Possible Cause Corrective Action
The reader does not recog-
nize a card/tag (no beep, no
LED flash)
1. One or more of the reader’s wir-
ing connections are incorrect
Power down the reader/access panel and verify the wiring
connection are correct for the reader/access panel combi-
nation.
2. The reader is not receiving
proper power from the access
panel
Verify the voltage supplied to the reader is between 5 and
14 VDC.
a
a. A supply voltage of 12 VDC at the reader is recommended for best operation.
3. The reader is mounted too close
to a device that radiates electro-
magnetic interference
Devices such as computer monitors radiate electromag-
netic interference that affects read range. When possible,
relocate either the reader or the device to provide greater
separation between the two.
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 reader/access panel is not
properly grounded.
Ensure there is a quality earth ground connection made to
the access panel. Refer to the access panel’s documenta-
tion for information regarding the earth ground connec-
tion.
2. The shield wire for the reader’s
cable has opened somewhere
between the reader and the
access panel.
Verify the shield line from the access panel to the reader is
one continuous, connected line. Refer to the access panel’s
documentation and verify the shield line is correctly con-
nected to the access panel.
3. The reader is mounted too close
to a device that radiates electro-
magnetic interference.
Devices such as computer monitors radiate electromag-
netic interference that affects read range. When possible,
relocate either the reader or the device to provide greater
separation between the two.
4. The power supply is generating
electromagnetic interference
The power supply on the access panel must be a regu-
lated, linear supply. Do not use switching supplies as they
are often sources of electromagnetic interference.
