Installation; Connecting Keypad Zones - Paradox DGP2-641 Reference And Installation Manual

2.0 INSTALLATION

The LCD keypads (DG2P-641 and DGP2-641AC) are connected to
the control panel's network in a star and/or daisy chain configuration.
This 4-wire communication network 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
(refer to Figure 1 on page 8). Refer to the Digiplex or DigiplexNE
Reference & Installation Manual for the maximum allowable
installation distance from the control panel.
See Figure 4 on page 10 for connection drawings for the REX
device, reader, locking device and door contact to the desired DGP2-
641AC keypad. A typical installation is shown in Figure 2 on page 9.
The door contact follows the control panel's EOL
definition. When EOL is enabled and the door contact is
not used, place a 1k
and BLK input terminals. If EOL is not enabled, use a
jumper. If the REX device is not used, place a jumper
across the keypad's Z2 and BLK input terminals.

2.1 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
1 on page 8. In order to communicate its status to the control panel,
devices connected to the keypad's input terminal must be assigned
