PRELIMINARY
Card Readers
When a proximity credential is presented to an internal or external reader, a beep
tone is heard and the Power/Armed LED blinks. This provides both an audible and
visual acknowledgement of the credential read.
Internal Access Control Reader
The 7863, and 7873 keypads provide a built-in proximity card reader designed to read
DMP/HID 1300 Series proximity credentials.
Note: For listed access control applications, the keypad must be installed within
the protected area.
External Access Control Reader
To accept Wiegand data input from other external card readers, connect a
12 VDC external reader to the 7873 keypad. Connect the Red and Black power wires
from the reader to the power wires from the panel. These connect in parallel with
the keypad power wires. Connect the Reader (Data 1) wire to the White wire on the
5-wire keypad harness. Connect the Reader (Data 0) wire to the Green/White wire
on the 5-wire keypad harness. See Figure 2.
