Installing the Keypad
All DMP keypad housings are designed to easily install on any single–gang switch box or flat
surface. Figure 3 shows the keypad housing base mounting hole locations.
Wiring Specifications for Keypad Bus
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
with a Model 7872 or 7873, do not exceed 225 feet. When using 18–gauge wire, do
not exceed 500 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 2.0VDC. 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 LX–Bus/Keypad Bus Wiring
Application Note (LT-2031) for more information. Also see the 710 Module
Installation Sheet (LT-0310).

Remove the Cover
The keypad housing is made up of two parts: the cover, which
contains the circuit board and components, and the base. Use the
following steps and Figure 1 to separate the keypad cover and base:
1. Insert a flat screwdriver into one of the slots on the bottom of
the keypad and gently lift the screwdriver handle toward you
while pulling the halves apart. Repeat with the other slot.
2. Using your hands, gently separate the front from the base and
set the cover and components aside.
Harness Wiring
1. Firmly grasp the wires near the base and hold the outside
edges of the keypad housing. Line up the red and yellow
wires with the guides on the board to inset the connector
into the J5 keypad terminal. See Figure 2.
Note: Do not remove the keypad housing to install the wiring
harness.
2. Observe wire colors when connecting the red, yellow, green,
and black wires to the keypad bus:
• Connect red wire to Panel Terminal 7
• Connect yellow wire to Panel Terminal 8
• Connect green wire to Panel Terminal 9
• Connect black wire to Panel Terminal 10

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
acknowledgment of the credential read.
Internal Access Control Reader
The 7873 and 7872 keypads provide a built-in proximity card reader designed to read
DMP/HID 1300 Series proximity credentials.

External Access Control Reader
To accept Wiegand data input from other external card readers, connect a 12VDC 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 3.
Magnetic Lock and Door Strike Wiring
The 7873 keypad provides one internal programmable
Form C single pole, double throw (SPDT) relay for
controlling door strikes or magnetic locks. Three wires
on the 5-wire harness, violet normally closed (N/C),
gray common (COM), and orange normally open
(N/O), allow you to connect devices to the relay. The
Form C relay draws up to 15mA of current and the
contacts are rated for 1 Amp at 30VDC maximum,
resistive.
Wiring the 333 Suppressor
One Model 333 Suppressor is included with
the 7873 keypad. If the device being controlled
by the relay is connected to the N/O and C
wires, install the suppressor on the N/O and
C wires. If the device is connected to the N/C
and C wires, install the 333 on N/C and C
wires. Refer to Figure 4a and 4b.
