SENSORS
Description
The PW-302 passive infrared (PIR) wall switch sensor turns
lights ON and OFF based on occupancy. It contains two relays
for controlling two independent lighting loads or circuits, and a
variety of features.
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 settings 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.
Optional Neutral Connection
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.
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.

OCCUPANCY & VACANCY
• Complies with 2011 NEC requirements
• Zero-crossing on both relays for long relay life
• Vandal resistant lens combines precise coverage 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
• In automatic mode, sensor returns automatically 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
