SENSORS
PW-302 Passive Infrared Dual Relay Wall Switch
Occupancy Sensor
High sensitivity and dense coverage
for exceptional performance
• Complies with 2011 NEC requirements
• Zero-crossing on both relays for long relay life
• Vandal resistant lens combines precise cover-
age with durability
• Selectable walk-through mode turns lights off
three minutes after the room is initially occupied
if no motion is detected after the first 30 seconds
• Test mode allows quick and easy adjustments
• LED indicates occupancy detection
• Selectable audible and/or visual alerts for
impending shutoff
The PW-302 passive infrared (PIR) wall switch
sensor turns lights ON and OFF based on occu-
pancy. It contains two relays for controlling two
independent lighting loads or circuits, and a variety
of features.
Optional Neutral Connection
Applications
The PW-302 sensor is great for retrofit projects
and well suited for small, enclosed spaces with a
clear line of sight of the occupant. In addition, its
dual relays allow bi-level switching or control of
a secondary load. Common applications include
small office, small conference room and lunch/
break rooms.
Operation
The PW-302 replaces existing wall switches and
installs in a single gang junction box with or
without either neutral wiring. Each of the PW-302’s
relays can control a separate lighting load. The
device uses advanced PIR technology to detect
occupancy and turn the first relay ON. The other
relay must be manually engaged to turn remaining
lights on. Once the space is vacated and the time
delay elapses, all lights automatically turn OFF.
Dual ON/OFF buttons allow the user to manually
turn on and off each of the loads. DIP switch set-
tings allow for a variety of control options such
as Manual-ON or Auto-ON for each relay, walk-
through and test modes. Multiple sensors may be
used for control of one or more loads from up to
four locations.

Product
Overview
Features
• In automatic mode, sensor returns auto-
matically to Auto-ON after lights are turned off
manually; ideal for presentations
• Optional light level sensor holds secondary
lights off when ambient lighting is above the
preset level
• Service mode allows sensor to operate as a
service switch in the unlikely event of a failure
• Sensor coverage tested to NEMA Guide
Publication WD 7-2000
• Compatible with decorator wall plates
The PW-302 sensor uses a patent pending Neutral
Sense Technology. Any PW-302 sensor can be
used for a two-wire or three wire application,
either to work with existing wiring, or to meet local
or national code requirements. An easy-to-break
plastic tab covers neutral screw terminals. Once
the sensor is connected to neutral it complies with
all codes that restrict current leakage to ground.
