Key Features
Common Features
• Passive infrared sensing technology
• Dual 120/277V AC operation
• No neutral required
• 1200 sq. ft. coverage
• Built in photocell for daylight harvesting
• Nylon wallplate included
• cULus, CEC Title 24 Certified
WS Series
• Manual adjustment time delay (20 sec. to 30 min.)
ATP Series
• Adaptive technology - “Install and forget” operation
Hubbell WS/ATP127x series wall switches combine PIR
sensing technology, photocell control, and Hubbell's
patented three wiring method to provide the perfect
light switch replacement solution. These sensors do not
require a neutral connection and they have no minimum
load requirements. The WS127x series has manual timer
adjustment while the ATP127x series incorporates Hubbell's
patented adaptive technology to automatically set timing and
eliminate manual adjustments.
The sensors come supplied with color matched faceplates.
Manual-on versions are available for enhanced savings.
Four wire models support installations that require a neutral
connection.
