7800 Series Keypad Installation Guide 3

Harness Wiring

Figure 5 shows wiring harness assignments. Observe wire colors when connecting the

red, yellow, green, and black wires to the keypad bus. Connect red to panel terminal

7, yellow to terminal 8, green to terminal 9, and black to panel terminal 10. Use 1k

Ohm EOL resistors, DMP Model 311, on keypad zones 1 through 4.

The 7872/7873 keypads are supplied with a 12-wire data bus/zone harness. Four

wires connect to the keypad bus. The remaining eight wires are for the four zone

inputs: two wires for each zone.

The 7873 keypad comes with one 5-wire output/reader

harness for connection of external reader/door strike and is

inserted into the J4 keypad terminal.

When replacing a 32-character keypad that uses a standard

12-position harness, the 300-7800-12ADPT 12-position wire

harness adaptor is available to adapt the larger connector to

the smaller 7800 Series connector (J5) without the need to

splice wires.

Note: Do not remove the PCB from the keypad housing to

install the wiring harness. 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

insert the connector into the J5 keypad terminal. See Figure 4

for example.

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).
