Troubleshooting the reader 43
1. If multiple beeps occur regularly, refer to the installation
drawings to verify that the correct pull-up resistor has
been added to the microcontroller.
2. Replace the reader with one you know is working
correctly. If this solves the problem, the original reader is
probably faulty and should be replaced. If the problem
persists, use shielded cable between the microcontroller
and the reader.
The reader sounds a short triple beep every 30 seconds and the
red LED flashes quickly (every 400 ms):
Indicates a tamper
violation. Verify that the reader housing is properly secured to the
backplate. If an external tamper is used, review the appropriate
recommended mounting instructions. If the reader is secure and
mounted properly, then the reader is faulty and should be
replaced.
The beeper and/or red LED are always on: The microcontroller
may command the reader to turn on the red LED and the beeper
as long as the reader DIP switches are not set to disable the
beeper. If the door status switch input at J1 pin 10 is not tied to
ground, the reader informs the system that the door is open. The
system may then activate the alarm at the reader. If this is not the
problem, then the system software probably told the reader to
activate its alarm. Refer to the appropriate system manual for
conditions that cause the software to activate the alarm. If it
appears that no such system command is active, replace the
reader with one you know works correctly. If this solves the
problem, the original reader is faulty and should be replaced.
The green LED flashes quickly (every 400 ms): This indicates
that the microcontroller has requested a PIN entry on a Model
972 or 973 Reader with a keypad. For all other models, check the
reader configuration on your system to be sure a keypad reader
was not selected.
