DGP2-641R LCD Keypad Module 3n

2.0 INSTALLATION

The DGP2-641R is connected to the control panel's combus in a star

and/or daisy chain configuration. This 4-wire combus 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 5). Refer to the DGP-848 or

DGP-NE96 Reference & Installation Manual for the maximum allowable

installation distance from the control panel.

See Figure 4 on page 7 for connection drawings for the REX device,

locking device and door contact to the desired DGP2-641R keypad

module. A typical installation is shown in Figure 2 on page 6.

The door contact follows the control panel’s EOL definition. When EOL is

enabled and the door contact is not used, place a 1k

Ω

resistor across the

keypad’s Z1 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.

Please consider the following when installing the DGP2-641R:

• Maintain all DGP2-641R wiring a minimum of 30cm (12”) away

from other wiring such as AC power, computer data wiring,

telephone wiring, etc.

• Avoid installing within 1.1m (3.5ft.) of computer monitors or

CRTs. The minimum distance will vary depending on the type of

monitor or CRT.

• Avoid installing in proximity to sources of broad spectrum EMI

noise such as motors, pumps, generators, DC to AC converters,

uninterruptible power supplies, AC switching relays, light

dimmers, computer monitors and CRTs.

• Avoid installing in proximity to potential sources of RF signal

transmitters such as cellular phones, two-way radios, etc.
