The Philips OccuSwitch Classic On/Off/
Automatic Dimming Photocell Sensor
combines the On/Off Photocell Sensor with
Automatic Dimming Control to provide the
industry’s most intelligent control of lighting
for daylight harvesting applications Ideal for
public spaces with windows like vestibules,
corridors, or bathrooms; the sensor works
by monitoring daylight conditions in a room,
then controlling the lighting so as to insure
that adequate lighting levels are maintained
The sensor has on/off lighting control; it
turns off the lights when sufficient daylight is
present and turns them on when additional
lighting is necessary This sensor is ceiling
mounted, line powered and can switch
loads directly without the need for a power
pack
Mounting
Wiring
Turn OFF breaker of all circuits involved. Wiring the
device with power ON could result in serious injury
or death.
Danger
Parts of the sensor carry line power, which
is a potential lethal voltage This product
was designed and manufactured to ensure
maximum safety during operation and
service Always read these safety
instructions before installing, maintaining or
servicing the product, and strictly comply
with these instructions
- This product should be installed by a
qualified electrician
- This device is designed for indoor use
only
- Disconnect power at circuit breaker or
fuse when servicing, installing or removing
- Only use with copper or copper clad wire
- Wire sensor to the line power according
to the wiring scheme in this guide
- To avoid short circuits, do not expose this
product to rain or condensing moisture
Short circuit may cause fire or electric
shock hazard Operate the devices
between 14°F to 160°F (-10°C to 71°C)
ambient temperature
It is the installer’s responsibility to ensure that the
e uipment being controlled is visible from every
control location and that only suitable e uipment is
connected to these controls. Failure to do so could
result in serious injury or death.
The product is intended to control lighting loads. Do
NOT use to control e uipment that could create
hazardous situations, like entrapment. For examples,
do NOT install this product to control motorized
gates, garage doors, industrial doors, microwave
ovens, heating devices, etc.
Warning
Note
Once installed, the sensor may take a few
minutes to become active Additionally,
there is a 45 second delay before switching
from “Off” to “On” (this delay is 55
seconds when connected to 50 Hz)
Important Safety Information
- Whenever it is suspected that an unsafe
condition exists, switch off power at the
circuit breaker and replace the device
Safety is likely to be impaired if, for
example, the equipment fails to perform the
intended functions or if the equipment
shows visible damage Do not paint the
device
- Use only a soft damp cloth to clean, never
use any abrasive or chemical cleaner

As daylight increases and decreases throughout the day, the Automatic Dimming Control feature adjusts the
0-10V output to vary the level of the connected loads. When sufficient daylight is present to maintain a level
of light e ual to or above the set-point level, the sensor will switch off the ballast completely.
