The diagram above shows how to connect
two keypads to control a single door.
Entering your code on keypad 2 unlocks the
maglock directly. When you enter your code
on keypad 1, it triggers the REX input of
keypad two, which unlocks the door
Please note that user codes must be
p
rogrammed into both keypads

TECHNICAL NOTES
This product was re-designed using a new
manufacturing technology, which changed the
physical appearance of the keypad electronics. The
LED’s changed to surface mount chip LED’s mounted
on bottom of the circuit board which eliminates the
need for the wire harnesses. It is also possible to
control the red and green chip LED’s externally, with
an alarm panel for example, by using connector J1.
See the diagram for details. Also, the voltage
selection jumper on the main circuit board is no
longer required.
To prevent electrical kick back voltage from damaging the
keypad, when using an electrical locking device, you
MUST install the transorb as close as possible to the lock.
Wire the transorb in parallel with the lock power terminals.
Also, to avoid ESD (electro-static discharge) from
interfering with the operation of the keypad, ground the
negative terminal of the keypad to earth ground. If you
cannot ground the power supply, then you must ground
the keypad housing.
IEI recommends using a filtered and regulated power
supply

To control the LED’s externally cut the four
traces in the box underneath connector J1.
Before connecting the alarm panel’s LED
control lines to J1 verify the traces are cut. To
verify, measure continuity between the end of
the wire on the wire harness and the square
pad on the circuit board below the box
corresponding to the wire you’re measuring.
Permanent damage to the keypad may
result if voltage is connected to J1 when
the traces are not cut.
