TIME CLOCK
If TIME CLOCK is enabled in Set up (pages 20 and 21), when the
CLOCK terminal on the ERM circuit is connected to ground –
through time clock or other switch contacts – all codes work
normally. When the CLOCK terminal is not grounded, only those
codes with 24-hour Access Authorization (page 21) will function.
The disabled codes are still considered valid and will not trigger
Tamper Alarm if tried repeatedly.

!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. 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:
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 (the RED LED will continue to flash and the
GREEN LED will be solid). If you hear a long error beep, re-
enter 98 followed by #. To change the audible beep or illumi-
nation, proceed as follows. Otherwise, go to step 5.
a. To change the audible beep, enter
Code Audible Beep
201 # Normal Beep (factory default)
200 # Short Click (quieter)
b. 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

b. Code Standby Mode Normal Operation
213 # Dim Dim
214 # Dim Bright
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 pro-
grammed 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 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.

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. Enter 98 followed by #. 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 98 followed by #. To change the audible beep
or illumination, proceed as follows. Otherwise, go to step 6.
a. To change the audible beep, enter the code as follows:
Code Audible Beep
201 # Normal Beep (factory default)
200 # Short Click (quieter)

Normal System Operation
When the system is first powered up (or when communication is
broken between the Keypad and the ERM3 module), the PRO-
GRAM button in the ERM must be pressed to establish the
encoded connection. This also puts the system into setup mode.
To end, 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. 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, 2
nd
Door or 3

!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 opera-
tion 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 the non-24 hour 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.

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 pro-
grammed, the unit will essentially be shut down.
Pressing the PROGRAM button while the unit has lost communi-
cation can cause the EC to be erased and will require an EC setup
upon re-establishing communication. For this reason, it is recom-
mended 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.
Since the output is on to indicate a Non-Alarm status when using
Output B relay as an Alarm, a loss of communication or invalid EC
will always create an alarm indication.
