Essex Electronics KE-265 - Manual (Page 6)

Install the Wiring Cable
1. Drill a ½” hole in the inside wall or ceiling where you want
the cable to come through.
2. Pull the cable through the hole so the connector end goes
to the keypad. Route it so there is minimal cable at the
keypad.
 Note: Supplied with the system is a 12-conductor cable
designed to connect the keypad to the control module.
You will also need a three-conductor cable (not included)
to connect the control module to the electric strike or other
locking device.
Mount the Keypad
1. Attach the wiring connector to the Keypad.
2. Attach the Keypad to the wall.
3. Do NOT attach the Keypad labels until the system is
tested.
Prepare the Door for the Electric Strike
Follow these instructions only if you are using an electric strike
to unlock the door. If you are using the main relay to activate
a garage door, automatic gate, etc., skip this section. The new
electric strike should be checked to verify compatibility with
existing door hardware prior to installation.
1. Remove existing strike.
2. Follow directions included with the strike for preparing the
doorjamb.
3. Do NOT mount the strike at this time.
Installing the Control Module
1. Connect the Wiring Cable to Terminal Strip “A” following
the color sequence on the circuit board. (Appendix A –
Page 23) NOTE: If the wiring cable has been cut shorter
than 15 feet, the tan wire will become exposed. The tan
wire is NOT used with the KE-265.
2. Connect 12 to 24 Volts AC to Terminal Strip “B” to screws
marked “12-24V AC/DC IN”. If using an Essex external AC
Adaptor, connect BLUE and BROWN to the 12-24V input
screws. Connect GREEN to the “EARTH” screw on
Terminal Strip “A”. Plug adapter into a grounded (three
terminal) receptacle.

 Note: If connecting DC, make the connections to
“DC IN/OUT” instead of “12-24V AC/DC IN”. Make
sure the polarity is correct.
⊗ IMPORTANT: The “EARTH” screw terminal on
Terminal Strip “A” should be connected to a true earth
ground for proper system protection and operation.
Connecting the Locking Device
Connect the electric locking device to Terminal Strip “B” as
outlined in the Typical Wiring Diagram (Appendix B – Page
24). Any 3 conductor, 18 gauge wire can be used to connect
the Control Module to the Locking Device. Included with each
system are two MOV’s (metal oxide varistor). The function of
the MOV is to absorb any inductive kickback from the locking
device, protecting the circuit board. The MOV’s have been
installed under the relay contact screws and can be left there
for
normal “FAIL SECURE” lock operation. For “FAIL SAFE”
locks, move one leg from the “N.O.” screw to the “N.C.” screw
(see Appendix B). If possible, install the MOV closer to the
electric lock. If switching voltages higher than 36V, remove
the MOV. To provide proper grounding, connect the 3
rd wire
from the body of the locking device to the “EARTH” screw on
Terminal “A”
Battery Backup
Although battery backup is NOT required for User Code
retention, you may wish to connect an optional Essex battery
charging module (part no. BC-01) and rechargeable Gel Cells
to the KE-265 to provide operation during a power interruption.
 Note: Although the system will operate on DC input, DC will
not charge the batteries for backup. If you require battery back
up, make sure your input is AC. Rechargeable batteries must
be used for back up.
