! Keypad Connector Diagram

The 5 wire harness connects the Keypad to the Prox Reader.

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 Output B is set up as 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.

RED, BLACK, GREEN, VIOLET, GRAY, ORANGE and SHIELD-

These wires all connect to the ERM module.

Security Level - Enabled

If SECURITY LEVEL is enabled in Set up (page 20):

When the CLOCK terminal on the ERM circuit is connected to
ground (through time clock or other switch contacts), users who
are “non-exempt” and were assigned both a code and card can
use either to enter. Those who were assigned only a card or a
code can also enter.

When the input is NOT grounded, only non-exempt users as­signed both a code and a card can enter by using both.

In other words, “grounded” is low level security; only one form of ID
is needed. “Not grounded” is high level security; two forms of ID
are needed.

Security Level - Disabled

If SECURITY LEVEL is disabled:

Whether the CLOCK terminal is connected to ground or not
grounded, “non-exempt” users with both a card and a code can
get in by using both. All other non-exempt users are locked out.

When programming Individual Users (page 21), assigning the
Exempt from Security Level User Authorization Code (7#) exempts
a User from the security level. All “exempt” users can get in with
either a code or a card no matter what the security level is set for.

! K-Prox Configuration

Voltage Selection

The factory default setting for the Keypad and Prox Reader
voltage is 12-24VDC. Verify that the jumpers are removed or
placed over only one pin. Do not set either for 5V.

Keypad Output Selection

Once the voltage jumper is verified or correctly set:

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, enter 98
followed by #. You should hear 3 beeps indicating successful
configuration. If you hear a long error beep, re-enter 98
followed by #. To change the audible beep, proceed as
follows. Otherwise, go to Step 5.

To change the audible beep, enter

Code Audible Beep

201 # Normal Beep (factory default)
200 # Short Click (quieter)

Essex Electronics, Inc. | 805.684.7601 | 800.KEY-LESS | fax [phone] | keyless.com

5. Remove power.

6. Remove configuration jumper.

7. Re-apply power.

8. Press PROGRAM button in the ERM to establish the encoded
connection. This will put the system into setup mode.

9. Press * * to exit.

CAUTION: This procedure completely erases the memory and
restores factory defaults! Once the memory is cleared, all pro­grammed User Codes are erased and factory default settings

are restored.

Keypad Reset

In certain cases you may want to erase all user codes and restore
system defaults. To perform this procedure:

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).

IMPORTANT: Once the configuration is selected, you must re­move 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.

Essex Electronics, Inc. | 805.684.7601 | 800.KEY-LESS | fax [phone] | keyless.com

4. Once the Keypad is in configuration mode, enter 0099#. The
Keypad will beep twice and both LEDS will flash for approxi­mately 10 seconds. (During this time, the Keypad will appear
dead. Do NOT remove power!)

5. Enter 98 followed by #. You should hear 3 beeps indicating
successful configuration. If you hear a long error beep, re­enter 98 followed by #. To change the audible beep, proceed
as follows. Otherwise, go to Step 6.

To change the audible beep, enter the code as follows:

Code Audible Beep

201 # Normal Beep (factory default)
200 # Short Click (quieter)

6. Remove power.

7. Remove configuration jumper.

8. Re-apply power.

9. Press PROGRAM button in the ERM to establish the encoded
connection. This will put the system into setup mode.

Normal System Operation

When the system is first powered up (or when communication is
broken between the Keypad and the ERM3 module), the PRO­GRAM button in the ERM must be pressed to establish the
encoded connection. This also puts the system into setup mode.
To end setup, press * * to exit. Or, the system will automatically
exit programming if no entries are made for 30 seconds.

! Keypad LED Status Indicators

! A flashing green LED indicates that the door is unlocked (mo-

mentarily).

! A solid green LED indicates that the door is unlocked (latched).
! A solid red LED indicates that the door is locked.

Depending on how the System Options are configured, User
Commands are used to operate Manual Latching. The User
Commands are trailing digits entered after an authorized user
code followed by # (enter) or card. The ability to use these User
Commands depends on authorizations assigned to each User
(see page 13 or pages 21-22).

As the Main Output activates, the green LED will flash for 5
seconds. While the green LED is flashing, enter one (or more) of
the following User Commands:

0 # to Latch the Door Closed (Main Relay, 2nd Door or 3rd Door)
1 # to Latch the Door Open (Main Relay, 2nd Door or 3rd Door)
2 # to Turn Output A OFF (2nd Output as Aux.)
3 # to Turn Output A ON (2nd Output as Aux.)
4 # to Turn Output B OFF (3rd Output as Aux.)
5 # to Turn Output B ON (3rd Output as Aux.)

! Tamper Alarm

An audible Tamper Alarm sounds when four incorrect code entries
are made. After 30 seconds, the unit returns to standby mode.

!!

!!

! Operation Notes

Pressing the PROGRAM button on the Encoded Relay Module
(ERM) sets a new Encode Code (EC) between the ERM and the
Keypad and puts the Keypad into Programming Mode. If no further
programming is required, press * * to exit.

If the ERM receives more than three (3) invalid EC’s in a row, the
unit will go into LockUp Mode. Once in LockUp Mode, the unit is
essentially shut down and can only be restored to normal opera­tion by pressing the PROGRAM button.

Upon communication loss or LockUp, all relays are released and
the Main Door latching is cleared if set. The Remote Bypass will
not work and the Keypad will be forced to Hi Security mode if
enabled. If communication is lost for more than 2 seconds, the unit
goes into LockUp Mode and can only be restored to Normal
Operation by pressing the PROGRAM button.

Essex Electronics, Inc. | 805.684.7601 | 800.KEY-LESS | fax [phone] | keyless.com

12

If communication is lost with the ERM or the ERM is in LockUp
Mode, the Keypad will indicate the problem by flashing the Red
LED very fast.

Since the Encode Code (EC) is only sent at the beginning of a
Latch Open sequence, this is the only time the unit knows if the
EC’s match. Upon a power up, both units will communicate with
each other and the second and third relays, remote bypass and
clock input will work normally. Upon the first attempt to send an
ERM packet with a non- matching EC, the device will be put into
the LockUp mode, and from that point, until a new EC is pro­grammed, the unit will essentially be shut down.

Pressing the PROGRAM button while the unit has lost communi­cation can cause the EC to be erased and will require an EC setup
upon re-establishing communication. For this reason, it is recom­mended that the Keypad and the ERM be powered by the same
power supply so they are both powered up and down at the same
time.

When using Output B relay as an Alarm, and since the output is on
to indicate a Non-Alarm status, a loss of communication or invalid
EC will always create an alarm indication.

Notes on Adding New Users:

! Auxiliary Device or 2nd or 3rd Door authorization depends on configura-

tion of the A and B Outputs. See System Setup on pages 3-4.

! If either Output is configured for 2nd or 3rd Door operation and a user is

given 4# or 6# Authorization, their User Code will activate the configured
output, not the Main Relay.

! Security Level restriction requires an external time clock or keyswitch.

This allows you to restrict access to Users who are not exempt. See Clock
Input on pages 6.
