7800 Series Graphic Touchscreen Keypad Installation Guide

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.

Installing the Keypad

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).

Installing the Keypad

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.

Using the 7800 Keypad for Access Control

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.
