Secure the reader to the wall plate
Align the reader so that the tabs of the base plate slide into the slots on the wall plate.
Slide the reader into position.
Secure the reader to the mounting plate using the supplied #4-40 screw or pin-in-Torx.
Power and test the reader
Power the reader and wait for the power-up LED beep sequence to complete. Present a valid credential to the reader
and the light-bar will turn green. If the test fails, check the wiring.
Additional information
Installation tips
When connecting the reader to a Wiegand panel, connect the Green wire to Data 0 and the White wire to Data 1.
When connecting the reader to an OSDP panel, connect the Green wire to RS485A and the White wire to RS485B.
For an OSDP system, verify that the panel is successfully communicating with the reader prior to reading a
badge or pressing a key.
Set the reader for Wiegand or OSDP
Note: Alarm.com readers are expected to ship in Weigand/Auto-Detect mode. Once a reader has been configured for
OSDP using the Auto-Detect process, it will remain in OSDP until the reader is put back into Weigand/Auto-Detect
mode.
The process for setting a reader for Wiegand or OSDP varies depending on the firmware version.
