Digital Switch Wiring
LiteKeeper® panels are capable of supporting a number of
digital switch device stations and 1 GDS-I gateway device
(the number the controller is able to support is dependent
on the number of other low voltage devices wired that
require power from our logic board. Please contact Technical
Support for exact details of how many devices your logic
board can power.) Refer to the chart below for the number
of digital switch device stations based on panel size. digital
switch cable type should be Eaton's Cooper Controls
LC Cable, Belden 1502R (non-plenum), or Belden 1502P
(plenum).
For best network performance, one of the suggested
cables should be used. If the specified cable is not
used and communications problems occur that require
troubleshooting assistance, additional charges for support
may be assessed.
Digital switches do not wire directly to the LiteKeeper®
panel, but are wired to a CAN Bus network that connects
to the LiteKeeper® through a GDS-I device Digital Switch
devices should be networked together in a daisy chain
configuration. No T-Taps/Stars should be used. The GDS-I
device should reside somewhere within the daisy chain
switch network. Total daisy chain network length should not
exceed 1000 feet.
The following instructions describe the GDS-I device
connection to the LiteKeeper®. Please refer to the
Greengate Digital Switch Installation Instructions included
with your Digital Switch Gateway for information on wiring
the Digita® Switch network to the Digital Switch Gateway.
1.
Mount the GDS-I next to the LiteKeeper® panel. A six
foot phone style wire has been provided for connection
to the LiteKeeper® panel.
2.
Run a length of the digital switch LC or Belden cabling
from the GDS-I location to the low voltage section of
the LiteKeeper®.
3.
Connect the RED wire in the cable to the +V terminal
on the back of the GDS-I and to the LiteKeeper®
remote power connector +24 VDC terminal.
4.
Connect the BLACK wire in the cable to the GND
terminal on the back of the GDS-I and to the
LiteKeeper® remote power connector DC
GND terminal.
5.
Tape back or cap the blue and white wires and shield
wire for the cable. They will not be used for connection
between the GDS-I and lighting controller.
6.
Locate the 6 foot phone style cable included in the
GDS-I box. Run this from the GDS-I into the low voltage
section of the LiteKeeper® enclosure plugging the end
with 9 pin head into the GDS-I. Plug the 9 pin COM
port end into the GDS-I. Plug the end the RJ11 phone
style plug into the LiteKeeper®. Ensure that the local
remote jumpers have been moved to the local position
(over pins 2 & 3) for both jumpers (J9 & J10) to enable
24 VDC to the low voltage switch channels. See Figure
LiteKeeper® Logic Board (16/32)
2 for location.

Applying Power
1.
After wiring is complete, make certain to clean panel
of all wire clippings and fragments ensuring that no
fragments get lodged between the circuit board
and enclosure.
2.
Ensure that there are no loose wires or exposed wires
that could short.
3.
Make certain that the relay communications cable (flat
ribbon cable) is securely plugged into the Standard
Override Card (SOC) located at the bottom of
the enclosure.
