DESCRIPTION

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.

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.

INSTALLATION

For an overview of the entire system, refer to the Lighting

Integrator Installation and Operation Manual.

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 de-•

energize 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.

Mounting

The LI-ARP is

provided with

a standard

½” threaded

conduit nipple

to facilitate

mounting to

any standard

J-box (not

supplied).

Figure 1: Mounting

Line Voltage Wiring

Make line voltage connections to the flying leads inside the

J-box using the color code provided on the label. Note that

the LI-ARP is a dual voltage capable device. Both brown

(277 volt) and black (120 volt) leads are provided. Cap off the

unused power lead with a wire nut.

Control power to the LI-ARP may be shared with the

controlled loads. It is acceptable for the control power

voltage to be different than the controlled load's voltage.

The LI-ARP has two electrically independent load control

relays. Connect one switched load to the red wires (Load #1)

and one switched load to the orange wires (Load #2). These

connections are not line/load sensitive.

Daylighting: If the LI-ARP will be equipped with a daylight

sensor, load #2 (orange wires) must be connected to the

lights that will be shed by the daylight sensor.

Low Voltage Wiring

Remove the LI-ARP's cover to access the connections and

configuration switches in the low voltage section. If the low

voltage wire will be run in conduit, connect the LI-ARP to the

low voltage wiring through a junction box.

CAUTION

RISK OF ELECTRIC SHOCK.

Wiring for Pilot Light Switches

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

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.

Three Wire Momentary Switch (factory default)

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).

LI-ARP

Once the switches are connected and power is applied to the

LI-ARP, the switches will control the loads.

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.

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.

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 SWITCHES

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 conﬁ guration

switches in the low voltage section of the housing

prior to closing up the housing and the ceiling.

Alternate Switch Operation

OVERRIDE SWITCH 1 and OVERRIDE SWITCH 2 can be

individually be configured for different switch types by

changing the position of the configuration DIP switches. The

tables below show the alternate configuration settings.

NETWORK CONFIGURATION

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 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.

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.

Switch number Value when ON Example

1 1 1 +

2 2 2 +

3 4

4 8 8 +

5 16

6 32

Total 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.

Network Wiring

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.

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.

Switches

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.

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.

OPTIONAL OCCUPANCY 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.

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 Occupancy Sensor

All connections to the occupancy sensor are through the low

voltage section of the LI-ARP.

1. Connect the red lead from the occupancy sensor to the

terminal labeled +24VDC (RED).

2. Connect the black lead to a COMMON terminal.

3. Connect the blue lead to CTRL-24V (BLUE) on the

OCCUPANCY SENSOR terminal bank.

Alternatively, if the sensor provides a dry contact relay

instead of a 24V signal, then connect the relay to the

COMMON and CTRL terminals.

4. Adjust the occupancy sensor as directed in the

installation instructions supplied with the sensor.

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.

Wiring the Daylight Sensor

All connections to the daylight sensor are through the low

voltage section of the LI-ARP.

1. Connect the red lead from the daylight sensor to the

terminal labeled +24VDC (RED).

2. Connect the black lead to COMMON.

3. Connect the blue lead to CTRL-24V (BLUE) on the

USING THE LIARP IN STANDALONE MODE

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, 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.

Stand-alone Mode Functions

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.

Relay 1 Switch Settings:

RL1AON OFF Manual ON (factory default)

RL1AON ON Automatic ON

Relay 2 Switch Settings:

RL2AON OFF Manual ON (factory default)

RL2AON ON Automatic ON

Blink Warn Switch Settings:
