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.
