Connecting Low Voltage Switches
3. If you are using a 32 size enclosure, make certain that
the upper back plate is in place, securing the back plate
with the 1/4 turn screws as directed in the enclosure
installation instructions.
4. Press and hold the two spring hinges on the back of
the logic board back plate towards the middle of
the plate.
5. Making sure there are no cables caught beneath the
logic board, slide the logic board into the bottom of the
enclosure in the mounting space provided, lining the
spring hinges up with the mounting holes, releasing the
spring hinges once the logic board is in place.
6. Swivel the logic board up, using the spring hinge at the
top of the board to secure the board to the top of the
enclosure or upper back plate in the slot provided.
7 . Connect the Relay Signal Ribbon Cable from the
logic board into the 40 pin connector on the Standard
Override Card (SOC).
Connecting Low Voltage Switches
The LiteKeeper® Logic Board can support a total of 64
switch inputs. Of these 64 inputs, 32 of them may be dry
contact closure inputs that are connected to the terminal
blocks at the bottom of the LiteKeeper® Logic Board.
Digital switch inputs may also be used on the LiteKeeper®.
If no contact input type switches are being used, the
full 64 switch inputs may consist of digital switches. If a
combination of contact input switches and digital switches
are being used, the combined total cannot exceed
64 inputs.
Regardless of switch type used, it is recommended that
all switch input wiring be done prior to applying power to
the logic board or at the very least with the terminal blocks
removed from the logic board.
Contact Input Switch Wiring
This section describes the wiring for dry contact closure
devices. There are thirty-two switch input wiring terminals
on the bottom of the LiteKeeper® to allow for wiring of the
dry contact closure devices.
1. All low voltage wiring is Class 2 wiring.
2. All low voltage wiring must enter the cabinet into the
low voltage section of the enclosure. Low voltage
wiring can be brought into the enclosure from the
bottom or bottom left of the enclosure. If low voltage
wire must be brought into the cabinet from the top
section, there is a knockout reserved on the left side
which will allow conduit to be run from the top of the
enclosure into the low voltage wiring area. Failure to
separate high voltage from low voltage wiring may
cause interference with logic board function.

3. All low voltage wiring must be run in separate conduit
from line voltage wiring.
4. Use 18 AWG twisted, unshielded wire for all low
voltage dry contact closure device wiring.
5. Maximum length for dry contact closure device wiring
is 1000 feet.
6. Test all low voltage wiring for shorts to AC Ground
before connection to the LiteKeeper® panel.
7 . When powering peripheral devices such as motion
sensors, photosensors, or digital switches from the
LiteKeeper® panel, there may be a limitation on the
number of sensors that can be supported. Please
contact Greengate for specific information on device
limitations if using these devices.
8. It is recommended that the terminal blocks be removed
from the board or power removed from the logic board
when doing initial switch input wiring.
9. Ensure that the local remote jumpers have been moved
to the local position (over pins 2 & 3) for both jumpers
(J5 & J6) to enable 24 VDC to the low voltage switch
channels.
10. Please see wiring detail in Figure 1 for details on
connections of different devices to the
LiteKeeper® system.
