Additional Power Supply
If the current draw for all keypads exceeds the panel output, provide additional
current by adding a Model 505-12 auxiliary power supply. Connect all keypad
black ground wires to the power supply negative terminal. Run a jumper
wire from the power supply negative terminal to the panel common ground
terminal. Connect all keypad power (+12 VDC) wires to the power supply
positive terminal. Do NOT connect the power supply positive terminal to any
panel terminal. Refer to the 505-12 Power Supply Installation Guide (LT-0453)
for more information.
Keypad Bus Monitor
For UL Listed re protective systems, the 893/893A Module must be installed in
the XR100/XR500 Series control panel to monitor the keypad bus and sound an
audible trouble whenever the keypad bus fails to operate. Refer to the
893/893A Module Installation Sheet (LT-0135).
Card Readers
When a proximity credential is presented to an internal or external reader, a
beep tone is heard and the Power and Armed LEDs blink. This provides both an
audible and visual acknowledgement of the credential read.
Internal Access Control Reader
The 7063/7063A, 7073/7073A/7163/7173, and 793 keypads provide a built-
in proximity card reader designed to read DMP/HID 1300 Series proximity
credentials.
Note: For UL Listed access control applications, the keypad must be
installed within the protected area.
External Access Control Reader
To accept Wiegand data input from HID, DMP, or other external card readers,
connect a 12 VDC external reader to the 7073/7073A/7173 or 793 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.
Door Strike Relay Specications (7073/7073A/7173, 793 only)
The 7073/7073A/7173 and 793 keypads provide one internal Form C single pole,
double throw (SPDT) relay for controlling door strikes or magnetic locks. Three
wires on the 5-wire harness, Violet (N/C), Gray (Com), and Orange (N/O), allow
you to connect devices to the relay. The Form C relay draws up to 15mA of
current and its contacts are rated for 1 Amp at 30 VDC maximum.
