Relay Status LEDs
These 32 LEDs are visible through the window in the panel
door. The LEDs correspond to relay outputs. When a relay
has been turned ON by the LiteKeeper® programming or
by a keypad override, the corresponding LED will be ON.
Please note that when the Standard Override Card override
switch has turned the relays ON, the LEDs will reflect
their current programmed status of the relays, not their
overridden state. The LEDs will show what relays will be ON
or OFF when the override switch is turned to the
AUTO position.

LiteKeeper® RS232 Port
The LiteKeeper® has an on board RS232 port for

System Reset and Clear Commands
Under certain circumstances, you may want to reset
the LiteKeeper®. There are two different types of reset
commands available in the LiteKeeper® system: a soft reset
command and a clear reset command.
Soft Reset Command:
A soft reset command is used to
initialize a new panel address with the panel. It can also
be used as a troubleshooting technique if the panel is not
responding or to free up the microprocessor if the unit's
STATUS LED is not flashing. The Soft Reset Command will
not cause loss of panel programming. To perform a Soft
Reset Command, press in and then immediately release
the reset button in the upper right corner of the logic panel.
When the reset button is pressed and released, the status
LED may hesitate briefly then resume normal operation.
In addition, the display may go blank then re-initialize. The
LiteKeeper® will issue the last known command to the
relays upon each reset.
Clear Settings Command:
used to remove all programming from a LiteKeeper®
unit. It should be done before programming the unit for
the first time or when asked to by a Technical Support
representative. Please use caution with this command!
When performing a Clear command, all relay loads will
turn OFF . Use the Standard Override Card switch to keep
lighting on if necessary. To perform a Clear command: Place
the override switch on the Standard Override Card in the
ON position. This will turn ON all the relays. If the override
switch is left in the AUTO position, all relays will turn OFF
after the memory is cleared. Hold down the Star (*) button
on the keypad. While holding the Star (*) button, press and
release the RESET button in the upper right corner of the
board. The display will read "INITIALIZING..." Once this
screen appears, you may release the Star key.
Programming the LiteKeeper®
The LiteKeeper® is programmed either through the
onboard keypad interface or through the optional Keeper
Enterprise Software. Please refer to Programming Guide
that came with the unit to program via the keypad or to
your Keeper Enterprise Manual for programming details.
It is recommended that a Clear Settings Command be
performed on the controller before the first programming is
done to clear any test data that may be left in the controller
from factory testing.
