Possible Solutions
None of the LEDs 
are on.
Check the following:
„
Power connections to the reader.
„
Reader supply voltage at connector pin 3 and 
that the ground connection pin 2 is secure and 
well connected.
The door does not 
open and the green 
LED does not light 
when a qualified 
credential is 
presented.
Verify that the door strike and the green LED are 
wired correctly. Verify that the access credential 
has been entered and that the reader has been 
properly configured in the host system.
The green LED 
does not light but 
the door strike 
unlocks the door 
when a valid 
credential is 
presented.
Verify that the door strike is wired correctly. Refer 
to the appropriate wiring diagram in your 
controller manual. Disconnect the wire from pin 7 
(green LED) and connect pin 7 to pin 2 (ground). 
If the green LED is now on, the reader is good and 
the connection to the reader is defective. If the 
green LED does not light, replace the reader.
