Troubleshooting
Issue
Explanation
Solution
LED’s cycling slowly from right to left.
The KP212 Mullion is designed to monitor for
low voltage. Once low voltage is detected, the
keypad turns off the backlighting to ensure
operation of the keypad until the problem can
be attended to.
Verify the power supply output voltage. If it is
below the voltage threshold of 7.5 Volts AC or
9 Volts DC, you must increase the voltage to
between 12-24 Volts.
LED’s cycling rapidly from left to right and the
keypad has lost all operation.
The KP212 Mullion is designed to monitor for
over voltage. This is a very “severe” condition
and signifi cantly affects the keypad’s
operation. Once the over voltage is detected,
the keypad shuts down all operation and
does not operate until the voltage is lowered.
Verify the power supply output voltage. If it
is over the voltage threshold of 35 Volts, you
must lower the voltage below 29 Volts.
Can’t access programming mode using the
master code.
The code you are entering is likely not the
master code.
Perform the program mode loopback in the
following section to enter program mode and
reprogram the master code.
No LED’s are lit on the keypad.
Power is not reaching the keypad.
First verify there is voltage at the keypad.
If not, verify there is voltage at the power
supply. If there is voltage, verify continuity
on the wires out to the keypad. Otherwise
contact the power supply manufacturer or IEI,
if there is a problem with the keypad. You also
may try power the keypad with a 12V battery
to verify operation.
DEALERS/INSTALLERS ONLY! End users must contact the dealer/installer for support. If the keypad still does not work after troubleshooting,
please call IEI’s techinal support department at 1-800-343-9502 (outside MA) or 1-800-733-9502 (inside MA).
Testing the Keypad
After installing the keypad, IEI recommends that you perform the keypad self-test once a year, to ensure that the keypad is working properly.
• To perform the self-test, with the unit powered up, press the following keys on the keypad: 7890#123456*
• If all 12 key presses are accepted, the keypad enters self-test mode.
• The LEDs alternate three times followed by the sounder beeping three times.
Program Mode Loopback
If you’ve forgotten the master code use the following loopback connection to enter program mode. Power down the unit, short the white/black
wire to the red wire, then power the unit back up. The yellow LED should be fl ashing. Now change your master code or reset the unit. Power
the keypad down and reconnected the wire harness in the original confi guration.
