Keypad Connector Diagram
○○○○
BLACK- Ground
YELLOW- Anti Tailgate
If not used, this must be connected to BLACK. By adding a door
monitor switch between YELLOW and BLACK, the door will relock
immediately after opening. If the third output is set up as an
Internal Alarm, this switch will trigger the alarm if the door is
opened without a code or if the door is left open longer than the
Door Ajar Time setting.
CONFIGURATION

PINK- Remote Bypass
Connect a Normally Open push button between PINK and BLACK
to trigger the main output for its normal Door Open Time setting.
ORANGE- Set Up Programming
Momentarily connecting ORANGE to BLACK puts the unit in Set
Up Mode (same as entering * 3, Master Code #).
GREEN- Optional Encoded Relay Module
GREEN is a special output for an optional “Secure/Encoded Relay
Module”. (Part No. ERM-3)
BROWN- 24-hour Access
If Time Clock is enabled in Set up (page 16) and the BROWN wire
is grounded, all codes work normally. When the BROWN wire is
not grounded, only those codes with 24-hour Access Authorization
(page 17) will function.
External Relay Wiring Diagram
Note: The Main, A and B Keypad outputs are transistor outputs
intended to drive an external relay.

Keypad Configuration
Voltage Selection
The factory default setting for the Keypad voltage is 12-24VDC.
Verify that the jumper is removed or placed over only one pin. For
5VDC, the jumper should be placed across both pins. If changing
the voltage is necessary, make sure the power is removed first.
Keypad Output Selection
Once the voltage jumper is verified or correctly set (see above):
1. Remove power.
2. Jumper the two pins above the connector labeled "CONFIG.”
3. Apply appropriate power. (You should hear 4 beeps and the
RED LED will flash and the GREEN LED will be solid).
4. Now that the Keypad is in configuration mode, select the
desired output by entering the configuration number followed
by #.
a. Keypad Output
Keypad Output Configuration
Self-Contained- ERM-3* 98 #
Self-Contained- Non-encoded 99 #
*Requires Essex Encoded Relay Module, which contains a serial
interface to connect a computer for programming and reading
codes, or a printer for real-time print-out of activities.
b. To change the audible beep, enter
Code Audible Beep
201 # Normal Beep (factory default)
200 # Short Click (quieter)

c. To change the illumination on the K1-26 only, enter the
code as follows:
Code Standby Mode Normal Operation
210 # Off (factory default) Off (factory default)
211 # Off Dim
212 # Off Bright
213 # Dim Dim
214 # Dim Bright
You should hear 3 beeps indicating successful configuration
(the RED LED will continue to flash and the GREEN LED will
be solid). If you hear a long error beep, re-enter the configura-
tion number followed by #.
5. Remove power.
6. Remove configuration jumper.
7. Re-apply power.
IMPORTANT: Once the configuration is selected, you must re-
move power, remove the configuration jumper and then re-apply
power in order to complete the configuration procedure. Note: If
the configuration jumper is not removed, the LED's will flash and
the Keypad will beep continuously.
Keypad Reset
In certain cases you may want to erase all user codes and restore
system defaults. To perform this procedure:

7
Essex Electronics, Inc. | 805.684.7601 | 800.KEY-LESS | fax [phone] | keyless.com
CAUTION: This procedure completely erases the memory and
restores factory defaults!!! Once the memory is cleared, all pro-
grammed User Codes are erased and factory default settings
are restored.
1. Remove power.
2. Jumper the two pins above the connector labeled "CONFIG.”
3. Apply appropriate power. (You should hear 4 beeps and the
RED LED will flash and the GREEN LED will be solid).
4. Once the Keypad is in configuration mode, enter 0099#. The
Keypad will beep twice and both LEDS will flash for approxi-
mately 10 seconds. (During this time, the Keypad will appear
dead. Do NOT remove power!!!)
5. Once the reset is complete, you will hear 4 beeps and the
RED LED will flash and the GREEN LED will be solid.
6. Enter the configuration number followed by #.
a. Keypad Output

Output Capabilities
Main Output
The main output is a transistor output intended to drive a relay
(see page 11) that will activate either a Fail-Safe or a Fail Secure
(Non Fail-Safe) electronic locking device or other equipment. It
may also be configured, with an external relay, as a dry contact
relay output to control a gate operator or garage door opener. The
main output is programmable from 01 to 99 seconds with optional
timed or manual latching.
Output A
A transistor output intended to drive a relay that can be pro-
grammed for one of the following:
1. CCTV or Light Controller - First key press triggers a Timed
Output (1 to 99 seconds).
2. Auxiliary Output - Manual Control or Timed Output (1 to 99
seconds).
3. Second Door - Users can be assigned to open a 2nd door.
