Wiring Specifications
When planning a keypad bus installation, keep in mind the following specifications:
1. DMP recommends using 18 or 22-gauge
unshielded
wire for all keypad and LX-Bus circuits.
Do Not
use
twisted pair or shielded wire for LX-Bus and keypad bus data circuits. To maintain auxiliary power integrity
when using 22-gauge wire do not exceed 500 feet. When using 18-gauge wire do not exceed 1,000 feet.
Install an additional power supply to increase the wire length or add devices.
2. Maximum distance for any one circuit (length of wire) is 2,500 feet regardless of the wire gauge. This
distance can be in the form of one long wire run or multiple branches with all wiring totaling no more than
2,500 feet. As wire distance from the panel increases, DC voltage on the wire decreases.
3. Maximum number of devices per 2,500 feet circuit is 40.
Note:
Each panel allows a specific number of supervised keypads. Add additional keypads in the
unsupervised mode. Refer to the panel installation guide for the specific number of supervised keypads
allowed.
4. Maximum voltage drop between the panel (or auxiliary power supply) and any device is 2.0 VDC. If the
voltage at any device is less than the required level, add an auxiliary power supply at the end of the circuit.
When voltage is too low, the devices cannot operate properly.
Refer to the 710/710F Module Installation Sheet (LT-0310) for more information. Also see the LX-Bus/Keypad Bus
Wiring Application Note (LT-2031).
Additional Power Supply
If the current draw for all keypads exceeds the panel output, you can 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 504-24 and 505-12 Power Supply Installation Guide (LT-0453) for more information.
Keypad Bus Monitor
For UL Listed fire protective systems, the 893/893A Module must be installed in the XR500 Series or XR200 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 and 7073 keypads provide a built-in proximity card reader designed to read HID 1300 Series and DMP 1400
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
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.
