Wiring a Request to Exit Device (REX)
The KP212 is equipped with a REX input. The normally open REX input triggers the main relay for the amount of time you programmed for the
master code. If the master code is set to toggle, the REX only triggers the relay for 5 seconds. There is no programming required for the REX
to operate.
1.
Connect the red (V+) and black (V-) wires to your power supply.
2.
Connect the common connection on the REX device to the negative on your power supply.
3.
Connect the white/black wire to the normally open connection on the REX device.
Wiring the Bell Output to a Speaker:
The KP212 keypad has a built in bell button, which triggers a relay output when pressed. This relay is normally open and the contact closes
when triggered. You can use this relay output to trigger devices that require a momentary closure, such as a doorbell. The relay output
provides a dry contact, but you can run up to 30VAC/DC through it for devices that require power to operate. The diagram below shows these
connections.
