Philips OccuSwitch Classic multi-tech sensors are the most advanced sensors available because they
combine multi-technology sensing with all digital architecture. They are designed to help eliminate false
triggering, resulting in trouble-free lighting control.
These sensors realize the benefits of both Infrared and Ultrasonic technologies for their performance and
reliability. Ultrasonic (Doppler shift) motion detection provides maximum sensitivity yet can be vulnerable
to false triggering from air conditioning currents, corridor activity and movement of inanimate objects. Infrared
motion sensing gives immunity to false triggering, but lacks sensitivity at greater distances. Upon room entry,
the infrared detects motion and turns the lights on. Ultrasonic sensors keep the lights on even when very
minor motion is detected. When unoccupied, lights stay off while air conditioning system cycles on and off,
and cleaning crews occupy corridors.
Features
• Infrared and ultrasonic signals, help to minimize false readings
• Digital technology uses a minimum of components for
reliability and lower cost
• A single mounting post and three color-coded wires
provide fast, simple installation
• Spherical section shape provides a sleek design that should
easily blend into the background
• Self-adjusting settings means that time delay settings are
continually adjusted helping to eliminate service callbacks
for simple adjustments
• Non-volatile memory means that learned and adjusted
settings are saved in protected memory, preventing status
loss during power outages
• Ambient light recognition helps to prevent lights from
turning on when the room is adequately lit by natural light
• Accurate consistent switching so that lights are on when
room is occupied, off when empty. Annoying false-offs are
minimized and lights on at night are eliminated
Coverage (Range)
• A wide variety of coverage areas including units
from 500 to 2000 sq. ft. is available
Compatibility
• Compatible with Philips Advance Optanium
programmed start electronic fluorescent ballasts
and Xitanium LED drivers
Applications
• Suitable for cafeterias, classrooms, computer rooms,
open offices, cubical areas, file rooms, executive offices,
board rooms, conference rooms, restrooms and other
open areas
