DESCRIPTION
INSTALLATION
The Automatic Relay Pack is a distributed control
device. It is designed for networked operation with the
Lighting Integrator Complete Control series lighting
control panel, or it can be used in stand-alone mode.
For an overview of the entire system, refer to the Lighting
Integrator Installation and Operation Manual.
With the LI-ARP, load control relays can be located in
the space where the control is required rather than
clustered in the lighting control panel. Further, all of
the low voltage Class 2 connections associated with the
space including wall switches, occupancy sensor and
daylight sensor, are terminated at the LI-ARP.
Up to 48 LI-ARP units may be connected on a single
digital dataline for system wide lighting control and
monitoring. This greatly reduces home run wiring
requirements for the installation while maintaining
capability for advanced system wide lighting control
functionality.
If you have any questions, call our Service Team at:
800.879.8585.
General Installation Information
• All power must be turned off prior to installation or
service.
• More than one disconnect may be required to deenergize power to the LI-ARP.
• External circuit protection to the LI-ARP is required (e.g.,
circuit breaker).
• Installation shall be in accordance with all applicable
regulations, wiring practices, and codes.
• Care should be taken to separate high voltage power
from low voltage (Class 2) control wiring.
Location Planning
The LI-ARP is often installed above the finished ceiling.
Therefore, be consistent in choosing the location for the
LI-ARP. This will help locate the LI-ARP units in the future
if they require service or adjustment. A good location choice
is directly above the wall switch(s) that are connected to the
LI-ARP. In a school, a good choice is in the hall directly above
the door to each classroom, to give easy access to the unit
without disrupting classroom activities.

Do not connect conduit runs directly to the low
voltage section of the LI-ARP. Make all splices in
the junction box, not in the LI-ARP. Do not run low
voltage wiring with line voltage or power wiring.
Wiring for Pilot Light Switches
Prepare low voltage wires
Low voltage wire used to connect the switches, occupancy
sensor, or daylight sensor is not required to be either twisted
or shielded. Use any appropriate stranded 18 gauge wire.
Terminals PILOT 1 and PILOT 2 supply 24VDC when the
corresponding relay is ON and can be used with appropriate
lamps to provide pilot status indication for the load relays.
Since in most LI-ARP installations the switches will be in
close proximity to the controlled lighting, the use of pilot light
switches is normally not necessary.
Wiring for Low Voltage Switches
Properly strip and crimp low voltage wires onto the 0.25"
quick connect lugs provided (use T&B crimp tool #WT145C,
WT2000, ERG2001, ERG2003 or WT1455). Lugs must be UL
listed, T&B #RA250 (22-18AWG) or equivalent to maintain
spacings on the circuit board. Terminate the lugs to LI-ARP
terminals as directed in this manual as described for the
device you are connecting.
Low voltage wiring should be stranded,18 gauge, plenum
rated wire.
Switch 1 controls load relay #1 (red power wires) and switch
2 controls load relay #2 (orange power wires). See figure 2
on page 2. Consult the graphic for location of these terminals
for OVERRIDE SWITCH 1 and OVERRIDE SWITCH 2.
LOW VOLTAGE SWITCHES
Three Wire Momentary Switch (factory default)
The LI-ARP is factory configured to use three wire,
momentary type low voltage switches such as Watt Stopper
LVS-1 or RS2-3. However, any center loaded double throw
toggle switch will work.
Factory default operation provides individual control of each
load relay by separate switches labeled OVERRIDE SWITCH 1
and OVERRIDE SWITCH 2. Both switches provide manual ON
operation; the lighting in the sensor-controlled space will not
come ON automatically. The user must operate the switch to
turn ON the lights. If this is the desired switch operation, no
further adjustments are required.
If other than default switch operation is desired, see
Alternate Switch Operation below. Set the configuration
switches in the low voltage section of the housing
prior to closing up the housing and the ceiling.
Connect the common connection from the three wire
momentary switch to one of the terminals labeled COMMON
in the LI-ARP. Connect the ON connection from the switch to
the terminal labeled A(ON) and the OFF connection from the
switch to the terminal labeled B(OFF).

NETWORK CONFIGURATION
Network Wiring
When used as part of the Lighting Integrator Complete
Control series lighting control panel network, up to 48
LI-ARP units may be connected on a single digital dataline
for system wide lighting control and monitoring.
Network wire should be Watt Stopper HDLW4 or HDLW4P
(plenum rated) as required for the site conditions. This wire
has two independent unshielded, 18 gauge twisted pairs. The
red/black pair is used for the LI-ARP network connection.
The blue/white pair should not be connected to the
LI-ARP. This pair is used only when HDLS series
dataline switches are part of the installation.
See the HDLS installation instructions for more
information on installing these switches.
Network Address
Set the network address of the unit using the ADDRESS
switches in the low voltage section of the LI-ARP. See figure 2
on page 2. Each LI-ARP in the network must have a network
address in the range of 1-48. This information is provided in
the submittal documents that came with your system. Set the
DIP switches according to the illustrations provided for each
LI-ARP in the submittal documents.
Connect the red/black pair to the NETWORK terminals A and
B using the push on connectors supplied. This connection
is not polarity sensitive. Either the red or black wire may be
connected to the A or B terminal.
For installations where factory submittal documents are not
supplied, it will be necessary to set the LI-ARP addresses
in the range of 1–48. In this case, the individual settings are
not important. However, each LI-ARP must have a unique
(relative to the panel it is attached to) network address in
order for the system to function properly.

The DIP switch address is set using a binary numbering
scheme where each DIP switch has a numeric value. The
address is determined by totaling the switch value for each
switch that is set to ON.

Example
The network wire need not be run in a daisy chain or any
other particular topology. Star, T-tap or other configurations
are permitted provided the total network wire length of the
segment does not exceed 1500 feet.
1+
2+
8+
If the installation requires more than 1500 feet of wire to
complete the segment, the wire must be run in a daisy
chain (linear) topology and termination resistors should be
installed at both ends of the segment. Contact Technical
Support for details or if the segment wire length will be
greater than 4000 feet. A network repeater will be required.
11
For example, with switch #4, switch #2, and switch #1 set to
ON, the address for this LI-ARP is 11. This is determined by
adding the switch values of 8 + 2 + 1 = 11.
Note: if the LI-ARP is to be used stand-alone (not on a
network), the ADDRESS must remain set at the factory
default of 0 (all address switches set to OFF). See the section
on Using the LI-ARP in Stand-alone Mode.

OPTIONAL OCCUPANCY SENSOR
OPTIONAL DAYLIGHT SENSOR
The LI-ARP is designed to work seamlessly with Watt Stopper
24VDC occupancy sensors. The sensor will provide local
overrides to the LI-ARP based on detection of movement
within the controlled space. The actual function of the sensor
depends on how it is configured in the WinControl software.
In all cases, the occupancy sensor will always affect both
load relays in the LI-ARP.
The LI-ARP is designed to work seamlessly with Watt
Stopper 24VDC daylight sensors such as the LS-100 and the
LS-101. The sensor provides a signal to either hold OFF or
shed load relay #2 when sufficient daylight is present.
Default operation for the occupancy sensor is manual
ON/automatic OFF. In this mode, the lighting is turned ON
manually using the low voltage wall switch connected to
the LI-ARP. The occupancy sensor will keep the lighting
ON as long as it senses motion. When the sensor times out
and turns OFF the lighting, an integral timer in the LI-ARP
provides a 5 minutes grace period during which a detected
motion will turn the lighting back ON. After the 5 minute
grace period expires, the manual ON feature is reset and the
wall switch must be used to turn ON the lights.
Wiring the Daylight Sensor
All connections to the daylight sensor are through the low
voltage section of the LI-ARP.

USING THE LI-ARP IN STAND-ALONE MODE
Stand-alone Mode Functions
The LI-ARP may be used in stand-alone mode (not connected
to a Lighting Integrator panel network). In this mode, the
LI-ARP typically receives a signal from an external system
such as a BAS or simple time clock switch to toggle the
operation of the LI-ARP between normal mode and “after
hours” mode of operation. To use the LI-ARP in stand-alone
mode, all of the ADDRESS switches must be set to OFF.
In stand-alone mode, all of the special functions of the LI-ARP
must be set using configuration switches in the low voltage
compartment of the housing. These include a selection for
Auto On or Manual ON for each relay, enabling Blink Warn,
and setting a Time Delay duration for after hour overrides.
The tables below show the special functions that must be
programmed with the configuration switches.
In stand-alone mode, the DAYLIGHT SENSOR input
terminals are used to provide the after hour mode signal
to the LI-ARP. A daylight sensor can not be used with
the LI-ARP when it is used in stand-alone mode.
An externally maintained contact closure between COMMON
and CTRL (on the bottom right corner of the low voltage
section – what would otherwise belong to the daylight section)
will place the LI-ARP into the after hour mode of operation.
An open condition between the COMMON and CTRL terminals
places the LI-ARP in normal operating mode.
The time delay setting will be in effect during after hour
periods and will be disabled during normal operating periods.
