Unison Paradigm® Light Sensor
Overview

The Unison Paradigm® Light Sensor provides light level measurement to the
connected Paradigm control system. The control system receives the measurements
to maintain a programmed lighting output in both dimmed and switched lighting
systems.

The Paradigm Light Sensors are available in three models:

• P-LS - Light Sensor with Controller

• P-LSC - Light Sensor Controller Only

• P-LSH - Light Sensor Only

Each controller supports an individual pair of Light Sensors and is available in neutral
white or black finish.

A light sensor may be installed within the controller or installed remotely, using up to
1,000 feet (304m) of 16 AWG wire per controller. When using a pair of light sensors,
both sensors transmit their light readings to a single controller which provides an
averaged reading to the connected Paradigm control system.

Wire Specification

Controller

The Paradigm Light Sensor utilizes LinkConnect to power the sensor and to provide
data to and from the connected Paradigm control system.

LinkConnect is topology-free and polarity independent. You can install your data runs
in any desired combination of bus, star, loop, and home-run. ETC recommends using
Belden 8471 (or equivalent) wire. The total combined length of a LinkConnect wire
run may not exceed 1,640 feet (500m), with a maximum distance of 1,312 feet (400m)
between any two devices.

ETC Installation Guide

Light Sensor

All control wiring should be installed and terminated by a qualified installer, should
follow standard wiring installation practices, and meet local codes. Leave
approximately 10 inches (254mm) of wiring in the junction box or tied back in the
ceiling to allow for wiring connections and future service needs.

Note:

ETC requires that all stations be grounded by using a 14 AWG (2.5mm2)
ESD drain wire.

Remoting the Light Sensor

The Paradigm Light Sensor Controller provides termination for up to two light
sensors. Each light sensor must be separately wired to the controller using no more
than 1000 feet (304m) of 16 AWG wire total per controller. These wire runs must
remain separate from LinkConnect wiring. ETC recommends using Belden 8471 (or
equivalent) wire.

Installation Environment

The Paradigm Light Sensor Controller is intended for installation to a finished ceiling
surface, soft ceiling tile, attached to a round fixture junction box or single-gang RACO
switch box. The controller operates in ambient temperatures of 0°C to 40°C, non­condensing humidity.

The Paradigm Light Sensor can be mounted directly in the controller, installed to a
1/2” conduit knockout or installed into a soft ceiling tile using the provided light
sensor thread extender. The light sensor can be installed outdoors when mounted to
a weatherproof enclosure. The sensor in this weatherproof installation scenario
operates in ambient temperatures of -25°C to 70°C.

Termination is available at the controller for LON
(LinkConnect) from the data source (Paradigm), and up
to two light sensors. Flexibility is provided with regards
to how the light sensor(s) is installed. You can install a
light sensor at the controller or up to two light sensors
can be installed remotely.

Light Sensor

Installation

The Paradigm Light Sensor is provided with a twist-lock mounting plate that can be
mounted to a finished ceiling, junction box, or soft ceiling tile. Determine the
installation method and follow the specific instructions detailed.

• "Junction Box Installation" on page 3

• "Soft Ceiling Tile Installation" on page 5

• "Installing the Light Sensors Remotely (optional)" on page 6

Note:

The LinkConnect pigtail and WAGO connectors provided are only
required when the sensor and controller are installed in series with other
sensors. If you are not continuing the data run, direct termination is
recommended on the sensor control board.

Junction Box Installation

Step 1:Pull Belden 8471 (or equivalent) and 14 AWG (2.5mm2) ground wire to the

junction box.
