4 Installer’s Guide

2.0 INSTALLATION

2.1 CONNECTING THE KEYPAD

The Digiplex™ LCD keypads are connected to the control panel's

bus in a star and/or daisy chain configuration. This 4-wire

communication bus provides power and two-way communication

between the control panel and all modules connected to it. Connect

the four terminals labeled red, black, green and yellow of each

keypad to the corresponding terminals on the control panel as shown

in Figure 2.1. Refer to the Digiplex Control Panel's Reference &

Installation Manual for the maximum allowable installation distance

from the control panel.

2.2 CONNECTING KEYPAD ZONES

Each keypad has one traditional hardwired input terminal, allowing you

to connect one detector or door contact directly to the keypad. For

example, a door contact located at the entry point of an establishment

can be wired directly to the input terminal of the entry point keypad

instead of wiring the door contact all the way to the control panel.

Connect the device to the keypad's input terminal as shown in Figure

2.1. In order to communicate its status to the control panel, devices

connected to the keypad's input terminal must be assigned to a zone

in the control panel and the zone's parameters must be defined. For

more information on zone assignment, please refer to the Digiplex

Control Panel's Reference & Installation Manual. Please note that

even with the ATZ (zone doubling) feature enabled, the keypad

supports only one detection device.
