WIRING THE XTREME™
The Xtreme™ keypad is a device which you choose to place either inside or outside the door.
IEI manufactures several other devices to choose from; keypads, magnetic card readers, proximity
card readers, and touch chip readers.
Choosing the correct device for the application is important. IEI manufactures light traffic and
heavy traffic devices. If you are not sure which device to utilize, please call us at 1-800-343-9502.
TESTING THE Xtreme™ KEYPAD FOR GROUND POTENTIAL DIFFERENCES
Wiring the Xtreme™ keypad to the programming control unit requires a four conductor,stranded
and shieldedcable to be wired between two units. Maximum lengths are as follows:
At the programming control unit, connect the four conductor cable to the four pin connector on the
controller relay board, as shown in the diagram above. The drain wire at the programming controller
must be attached to ground, also the foil shield should be cut back with the insulator and taped with
electrical tape. Ground is the V- terminal on TS1 if the power supply is grounded. At the
Xtreme™ keypad, the drain wire and foil shield is cut back with the insulator and taped with electri-
cal tape. The four conductor harness connects into the four wire harness on the Xtreme™ keypad.
Both wire harnesses are connected to each other color to color.
22 AWG stranded : 250 feet
20 AWG stranded : 500 feet
18 AWG stranded : 1000 feet
48”
If the Xtreme™ keypad is mounted to the metal door frame of the building, a ground potential
test should be run. This test is important because a potential difference between the power supply
ground and the ground on the metal frame of a building can render the system inoperable. The
Xtreme™ keypad should first be installed and the power supply grounded and turned off. Now set
up a meter to read DC voltage. At programming controller separate the black wire of the four con-
ductor cable from the wire running to the Xtreme™ keypad and attach the meter in series with the
two wires per diagram above. If the meter shows more than one volt then the front end must either
be insulated from the frame or the ground wire of the reader must be removed. Setup meter to read
AC voltage and repeat test. On the Xtreme™ keypad you will find the grounding wire screwed to
the case at one end and plugged into the circuit board on the other end. If you have any questions
about this procedure please call IEI Technical Support,1-800-343-9502.
