Wiring to a Request to Exit (Push to release):
The 212iLM Mullion keypad may be wired to accept an input from a remote-switching device. This is a
momentary input that will engage the main relay for the same amount of time that the master code is
programmed with. This input requires a normally open, momentary closure between the White with a
Black trace wire and the Black wire. The only time the REX won't follow the main relay time is if the
Master code has been programmed to latch the main relay. In this case, the REX will operate with the
default time of 5 seconds. You may wire in several devices parallel to release the door from different
locations but they must all be normally open devices. There is no programming required for this option.
The 212 iLM needs normally open DRY contacts to operate the relay with the REX input. If your remote exit
device sends voltage when it is pressed, you MUST connect an external relay to the wires coming from the
REX, then connect the 212iLM Mullion REX connections to the common and the normally open connections
on the external relay.
Step 1: Connect the White with Black trace wire on the 212iLM Mullion harness to the common
connection on the REX device.
Step 2: Splice a wire to the Black (negative) wire on the 212iLM Mullion harness and connect to the
Normally Open connection on the REX device.
Example of wiring to an IEI request to exit device (part #EZ-REX):
Wiring the Bell Button:
There are 2 white wires on the 8 conductor harness, an A(common) and a B(normally open) for the bell
button. This is a dry contact, normally open form A relay. Connect positive (from power) to common (A)
of the 212iLM wiring harness. Connect normally open (B) of the 212iLM harness to positive terminal of
bell or speaker. Then connect the negative of bell or speaker to the negative of the power supply.
Step 1: Connect the Black (Negative) wire from the 212iLM Mullion harness to the Negative connection
on the doorbell speaker and splice it into the negative wire from the power supply.
Step 2: Connect the White (Common-A) wire from the 212iLM Mullion harness to the Positive connection
on the doorbell speaker.
Step 3: Connect the White (Common-B) wire from the 212iLM Mullion harness to the Positive wire from
the power supply.

qSection 4: Power Up
Making the Power Connections: (The 212iLM Mullion is powered with 12-24 Volts AC or DC ONLY)
Step 1: Connect the Red (positive voltage input) wire from the 212iLM Mullion harness to the positive
voltage output connection on the power supply.
Step 2: Connect the Black (Negative voltage input) wire from the 212iLM Mullion harness to the negative
voltage output connection on the power supply.
Step 3: Plug in the power supply.
Upon power up, the 212iLM Mullion will cycle through the LED's from left to right twice to indicate proper
keypad operation. (If the LED's continue to flash, refer to the trouble shooting section of this manual on
page 14). The backlighting will now be on and will dim 15 seconds after the last keypress or 5 seconds
after the programming mode has been exited. The red LED should now be on. Perform the Self-Test by
pressing 7890#123456*. The LED’s will cycle from Green to Yellow to Red and then the sounder will
beep three times. Press 1234*and the main relay should energize for 5 seconds and the green LED
should light for the time the relay is open. After the relay closes, the green LED should turn off and the
red LED should come back on.

qSection 5: Programming the 212iLM Mullion
The 212iLM Mullion supports 120 user codes that will energize the main relay. A user code is stored in
the memory of the 212iLM Mullion with an individual user location, and may be 1 to 6 digits in length.
Each user code has a corresponding user location. To help with the understanding of user locations,
think of them like shelves. The 212iLM Mullion has 120 shelves (user locations) in it, and each user code
gets put into its own shelf (user location). For example: the Master code (factory defaulted to 1234), is
always stored as user location 1. Every time a new user code is added, a new user location must be
used. To do any programming the 212iLM Mullion must be put into the Programming Mode. The keypad
will come out of programming after 45 seconds if no keys are pressed.
Step 1: Entering the Programming Mode.
Programming mode is accessed by entering the following command.
99 followed by the # key.
Next the current Master Code has to be entered. The default master code is 1234.
Then finish the command by pressing the *key.
Example: 99 # 1234 *(the yellow LED will flash to indicate it is in programming.)
NOTE: Entering an additional *at this time will exit programming mode.
If the programming command was done successfully, the 212iLM Mullion starts flashing the yellow
LED slowly, indicating that it is now in programming mode. If the yellow does not come on flashing,
that is an indication that the incorrect Master code was entered. (See the trouble shooting section of
this manual on page 14 if this does not happen.)
Step 2: Changing the Master Code.
The 212iLM Mullion comes with the factory programmed Master code of 1234. This may be
changed to any code that has 1 to 6 digits in length. The 212iLM Mullion also comes set from the
factory with a 5-second relay activation time that may be changed to any time from 01 to 99
seconds, or 00 to latch (toggle) the relay.
The 212iLM Mullion has to be in programming mode before you can change the Master code.
To Change the Master code:
Enter Programming Mode: 99# (Master code) *(Yellow LED flashing slowly).
Next enter user location "1" which is always the Master code’s user number followed by the # key.
Next enter in the new Master code followed by the *key (Yellow LED flashes rapidly).
Repeat the new Master code followed by the *key. (Yellow LED will flash slowly).
If the change was successful, the yellow LED will still be flashing.
Example: 1 # 4321 *4321 *
Continue programming or press the *key again to exit.
To Change the Main Relay Activation Time:
Enter Programming Mode: 99# (Master code) *(Yellow LED flashing slowly).
Next enter the relay activation time in a two digit format (01 to 99 seconds or 00 to toggle or latch the
main relay.) followed by the # key.
Next enter user location "1" which is always the Master code’s user number followed by the # key.
Next enter in the Master code followed by the *key (Yellow LED flashes rapidly).
Repeat the Master code followed by the *key. (Yellow LED Will flash slowly).
If the change was successful, the yellow LED will still be flashing.
Example: 08 # 1 # 4321 *4321 *(sets output to 8 seconds for the master code of 4321)
Example: 00 # 1 # 4321 *4321 *(sets output to toggle on, toggle off with a code of 4321.)
Continue programming or press the *key again to exit.
NOTE: All user codes will follow the main relay time that is programmed into the master code. If a toggle
code is entered as the master code, all user codes will toggle unless otherwise specified.

6051344 Rev. 1.0

Step 3: Adding or Changing User Codes.
User codes may be 1 to 6 digits in length.The 212iLM Mullion has to be in programming mode to add or
change users
Enter Programming Mode: 99#(Master code) *
Next enter the user location. (2, 3, 4, etc.) followed by the # key.
Now enter the new code followed by the *key (Yellow LED flashes rapidly).
Repeat the new code followed by the *key (Yellow LED flashes slowly).
If the change was successful, the yellow LED will still be flashing slowly. Codes entered in this fashion
hold the relay time programmed with the master code.
Examples: 2 # 6789 *6789 *
3 # 53780 *53780 *
4 # 23966 *239646 *
Continue programming or press the *key again to exit.
Step 4: Creating a User Code With a Different Time, or to Latch/Toggle the Main Relay.
The 212iLM Mullion has to be in programming mode to add or change users
A latching or toggle code is used to open the relay for an indefinite amount of time. This operates much
like a light switch. When you enter a latching user code, the Main relay will activate and stay opened until
the same code or another latching user code is entered to close the relay.
Enter Programming Mode: 99#(Master code) *
Next enter the relay time of "00" followed by the # key.
Next enter the user location. (2, 3, 4, etc.) followed by the # key.
Now enter the new code followed by the *key (Yellow LED flashes rapidly).
Repeat the new code followed by the *key (Yellow LED will flash slowly).
If the change was successful, the yellow LED will still be flashing slowly.
Examples: 00 # 12 # 7788 *7788 *
00 # 55 # 6632 *6632 *
00 # 93 # 78651 *78651 *
Continue programming or press the *key again to exit.
Adifferent output on the main relay may be desired for one or more users. For example, an individual
may require several extra seconds to open a door than everyone else. If the main relay is set for 5
seconds, that person may need 10 seconds. A different output time for individual users is programmed
this way.
Enter Programming Mode: 99#(Master code) *
Next enter the relay time of "10" followed by the # key.
Next enter the user location. (2, 3, 4, etc.) followed by the # key.
Now enter the new code followed by the *key (Yellow LED flashes rapidly).
Repeat the new code followed by the *key (Yellow LED will flash slowly).
If the change was successful, the yellow LED will still be flashing slowly.
Example: 10 # 12 # 7788 *7788 *
10 # 55 # 6632 *6632 *
20 # 93 # 78651 *78651 *
Continue programming or press the *key again to exit.

Step 5: Changing the 212iLM Mullion Feedback Options.
The 212iLM Mullion has two keypress feedback options that you may choose from. One is an audio feed
back. This will activate the on board sounder every time that a key is pressed. The other is a visual
feedback. This will flash the yellow LED on the front of the keypad every time that a key is pressed.
These two options are used to verify when a key has been pressed. Both of these options may be used
individually, together or not at all. They are enabled by default.
Audio Option:
Enter Programming Mode: 99# (Master code) *
Next press Command number 30 followed by the # key.
Next press "0" for the audio feedback option followed by the # key.
Next press "0" to Disable or "1" to Enable the audio option followed by the # key.
Next press the *key (Yellow LED flashes rapidly).
Next press the *key (Yellow LED will flash slowly).
Example: 30 # 0 # 0 # **(This will disable the sounder from activating every time a key is pressed).
Example: 30 # 0 # 1 # **(This will enable the sounder to activate every time a key is pressed).
Continue programming or press the *key again to exit.
Visual Option:
Enter Programming Mode: 99# (Master code) *
Next press Command number 30 followed by the # key.
Next press "1" for the visual feed back option followed by the # key.
Next press "0" to Disable or "1" to Enable the visual option followed by the # key.
Next press the *key (Yellow LED flashes rapidly).
Next press the *key (Yellow LED will flash slowly).
Example: 30 # 1 # 0 # **(This will disable the yellow led from activating every time a key is pressed).
Example: 30 # 1 # 1 # **(This will enable the yellow led to activate every time a key is pressed).
Continue programming or press the *key again to exit.
Step 6: Auto-Entry.
Auto entry is used to turn off the star *key. The user only needs to enter their code number without the
star key and the relay will activate for the programmed relay time. To use this feature, the user codes
must be the same length as the Master code. This feature is disabled by default.
Enter Programming Mode: 99# (Master code) *
Next press Command number 30 followed by the # key.
Next press "2" for the Auto-Entry option followed by the # key.
Next press "0" to Disable or "1" to Enable the Auto-Entry option followed by the # key.
Next press the *key (Yellow LED flashes rapidly).
Next press the *key (Yellow LED will flash slowly).
If the change was successful, the yellow LED will still be flashing slowly.
Example: 30 # 2 # 1 # **(This will remove the *key from the code).
Example: 30 # 2 # 0 # **(This will add the *key to the code).
Continue programming or press the *key again to exit.

Step 7: Doorbell Option:
When the doorbell feature is enabled there will be visual and audio keypress feedback for the bell button
but when the feature is disabled there will be no keypress feedback. This doorbell feature has two modes
of operation: timed and continuous. Timed will allow programming of the output for a specified number of
seconds with a single short press. The doorbell is set for continuous by default and output bell sounds for
as long as the button is pressed.
Enabling or disabling Doorbell Option:
Enter Programming Mode: 99# (Master code) *
Next press Command number 30 followed by the # key.
Next press "5" for the doorbell option followed by the # key.
Next press "0" to Disable or "1" to Enable the doorbell option followed by the # key.
Next press the *key (Yellow LED flashes rapidly).

Programming Options Chart
If the pre-programmed default values must be changed or additional functions are desired, the following
options may be programmed.
•Enter programming mode Press: 99 #(master code)*
The master default code is 1234 and the 212iLM must be in programming to make any changes.
•Changing the master code Press: 1 # (new code)*(repeat code)*
•Change the main relay activation time: Press: (relay time) # 1 # (mastercode)*(repeat code)*
All main relay times are entered in a 2-digit format. For example: 08 for eight seconds.
Example: Master code with an 8 second relay time: Press: (08) #1 #1234 *1234 *
•Add or change user codes Press: (user location) # (new code)*(repeat code)*
Codes entered in this fashion will hold the same relay time that the master code is programmed with. If the
relay time is changed after all other programming is done, the codes will not follow the master code for time.
You will have to either change time manually or reset defaults and reprogram. User locations are explained in
Section 5.
•Add a user to latch the main relay: Press: (00) # (user location) # (new code)*(repeatcode)*
•Add a user with a different output time on the main relay: Press: (relay time) # (user location) # (new
code)*(repeat code)*
Example: User code with a 8 second relay time Press: (08) #2 #1234 *1234 *

Section 6: Trouble Shooting.
Refer to this section if the 212iLM Mullion is not responding correctly to the operation outlined in this
instruction manual. The 212iLM Mullion has been designed to operate with 12-24 Volts AC or DC.
Verify that the voltage powering this keypad is within these parameters.
Situation 1: LED's are slowly cycling from right to left and the Backlighting is off.
Reason: The 212iLM Mullion has been designed to monitor for low voltage. Once the low
voltage has been detected, the keypad shuts down some of its options like
backlighting to ensure operation of the keypad until the problem can be attended to.
Solution: Check the output voltage of the power supply with a meter to verify the output voltage
rating listed for that device. If it is below the voltage threshold of 7.5 Volts AC or 9
Volts DC, you must increase the voltage to between 12-24 Volts.
Situation 2: LED's are rapidly cycling from left to right and the keypad has lost all
operation.
Reason: The 212iLM Mullion has been designed to monitor for over voltage. This is a very
"severe" condition and therefore significantly affects the keypad’s operation. Once
the over voltage has been detected, the keypad shuts down all operation and will not
operate until the voltage irregularity has been corrected.
Solution: Check the output voltage of the power supply with a meter to verify the output voltage
rating listed for that device. If it is over the voltage threshold of 35 Volts, you must
reduce the voltage to under 29 Volts.
Situation 3: The Master code is not allowing access to the programming mode.
Reason: There are a few reasons that this situation could occur. The most common is that the
Master code was programmed incorrectly. That is to say that someone entered a
user code into user number one. The Master code is always kept in memory with
user number "1" and users are in positions “2” through “120”.
The other reason this could happen is that the code was simply forgotten.
Solution: Power down the keypad, connect the white/black wire to the Red wire on the 212iLM
Mullion wire harness and power back up. The yellow LED will be flashing indicating
that the keypad is now in programming mode. Change the Master code by press 1 #
(New Master Code) *(Repeat Master Code) **. When finished with programming,
power down the unit, separate the white/black wire from the Red wire on the 212iLM
Mullion harness and power back up. The keypad is now ready to use.
Situation 4: No LED's are lit on the keypad
Reason: Power is not reaching the keypad.
Solution: With a meter check the voltage connection at the 212iLM Mullion keypad on the Red
& Black wires. Confirm that there is actually voltage at the keypad. If there is no
voltage reading at the keypad, use the meter on the power supply to verify that
voltage is leaving the power supply. If there is no voltage coming out of the power
supply, call the manufacturer of that power supply. If there is voltage at the power
supply, but not at the keypad, use the meter to test each of the wires for a break in
the wire. You may also use a 12-Volt Battery to power the 212iLM with, in order to
verify that it is functioning.
