5. When powering peripheral devices such as motion
sensors and photocells from the LiteKeeper panel,
there may be a limitation on the number of sensors
that can be supported. See the recommendations
below or contact Eaton’s Cooper Controls for further
information.
6. It is recommended that power be removed from the
logic board when doing initial switch input wiring.
Contact Input Switch Wiring
This section describes the wiring for dry contact closure
devices. There are four switch input wiring terminals on the
bottom side of the LiteKeeper 4® low voltage section to
allow for wiring of the dry contact closure devices.
1. Use 18 AWG twisted, unshielded wire for all low
voltage dry contact closure device wiring.
2. Maximum length for dry contact closure device wiring
is 1000 feet.
3. Please see wiring detail below for details on
connections of different devices to the LiteKeeper 4®
system.

Sensor Notes
It is possible to use a contact input photosensor and
Greengate motion sensors in conjunction with the lighting
control system. The LiteKeeper 4® is capable of powering a
number of these devices. Please refer to the chart below for
details on how many devices the transformer can support.

Please contact technical support if it is necessary to power
additional sensors beyond the numbers listed above. If
using a combination of devices, please contact technical
support for precise limits on the number of devices the
logic panel can power.
Photocell and Motion Sensor Wiring
Applying Power
1. Once the wiring is complete, make certain that the
enclosure is clean of any wire clippings and that no
fragments are lodged in the relay circuit boards.
2. Ensure that there are no loose wires or exposed wires
that could short to other wires or components.
3. Power-up the unit from the circuit breaker.
4. Once power is applied to the unit, lighting loads may
be operated via the ALL ON/ AUTO/ ALL OFF switch as
necessary.
Manually Controlling Relays
The relays in the enclosure may be controlled before the
logic board is programmed by using the on-board, ALL OFF,
AUTO, ALL ON switch. In the ALL ON position the relay
coils will be energized. In the ALL OFF position, the relay
coils will be de-energized. The middle, AUTO, position allows
the relays to be controlled by the individual relay switches or
from the logic controller.
