2.0 Installation
2.1 Connecting the Keypad
The DGP2-640 is connected to the control panel’s combus in a star
and/or daisy chain configuration. The four-wire combus provides
power and two-way communication between the control panel and all
modules connected to it. Connect the four terminals labeled
+
, - ,
GRN
and
YEL
on the keypad to the corresponding terminals on the control
panel as shown in Figure 1 on page 3. Refer to the control panel’s
Reference & Installation Manual for the maximum allowable
installation distance from the control panel.
2.2 Connecting the Keypad Zone
Your keypad has one hardwired input terminal, allowing you to
connect one detector or door contact directly to it. For example, you
can wire a door contact located at the entry point of an establishment
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 3.
The keypad zone follows the control panel’s EOL definition.
In order to communicate its status to the control panel, the keypad's
input must be assigned to a zone in the control panel and the zone's
parameters must be defined.
The control panel does not recognize tampers originating
from the keypad zone.
For more information on zone assignment, please refer to your
control panel's
Reference & Installation Manual . Please note that
even with the ATZ (zone doubling) feature enabled, the keypad
