Description
Optional Neutral Connection
­­­­­­­­ he DSW-302 dual technology wall switch sensor turns lights
T
ON and OFF based on occupancy and contains two relays
for controlling two independent lighting loads or circuits. It
combines the benefits of passive infrared (PIR) and ultrasonic
detection technologies for high sensitivity to small and large
movements. The DSW-302 replaces existing wall switches and
fits a standard decorator wall plate.
The DSW-302 sensor uses a patent pending Neutral Sense
Technology. Any DSW-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.
Operation
Applications
Each of the DSW-302’s relays can control a separate lighting
load. By default, when the PIR sensor detects occupancy, relay
1 turns ON automatically. Remaining lighting must be turned
on manually. Detection by either PIR or ultrasonic technology
holds lights ON. When occupancy is no longer detected and the
time delay elapses, lights automatically turn OFF. Dual ON/
OFF buttons allow the user to turn on and off each of the loads
manually. DIP switch settings allow for a variety of control
options such as Auto-ON or Manual-ON for each relay, walkthrough, and test mode. Multiple sensors may be used for
control of one or more loads from up to four locations.
The DSW-302 sensor is great for retrofit projects and has the
flexibility for applications where one technology alone may not
be sufficient. In addition, its dual relays allow bi-level switching
or control of two loads. Applications include small and executive
offices, small and medium conference rooms and lunch/break
rooms. This sensor is also a perfect choice for ADA-compliant
buildings due to lower mounting height requirements.
Features
• 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
• Selectable audible alert for impending shutoff
• In automatic mode, sensor returns automatically to Auto-ON
after lights are turned off manually; ideal for presentations

• Test mode allows quick and easy adjustments
• Four occupancy logic options to customize control to meet
application needs
• 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
