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 the circuit board that eliminates the need for the
wire harnesses. 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

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 2, which unlocks the door.
When using a propped door or forced door alarms, connect the alarms to
keypad 2. Also use keypad 2 to shunt out an existing alarm system with
the alarm shunt relay.
Please note that user codes must be programmed into both keypads.
