Installation and
Programming Guide
Mounting
The sensor enclosure accommodates
mounting to a variety of junction boxes
ranging in size from a single gang mud ring
at a 3.28" spacing, up to a round fixture box
spacing of 3.5".
Wiring
Danger
Turn OFF breaker of all circuits involved. Wiring the
device with power ON could result in serious injury
or death.
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).

Product Description

The Philips OccuSwitch Classic On/Off
Photocell Sensors 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 sensors work
by monitoring daylight conditions in a room,
then controlling the lighting so as to insure
that adequate lighting levels are maintained.
They have on/off lighting control; they turn
off the lights when sufficient daylight is
present and turn them on when additional
lighting is necessary. These sensors are
ceiling mounted, line powered and can
switch loads directly without the need for a
power pack.

Important Safety Information

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.
Daylight Harvesting
As daylight increases and decreases throughout
the day, the connected loads are switched off and
on based on the programmed set-point. When
sufficient daylight is present to maintain a level of
light equal to or above the set-point level, the
sensor will switch off the ballast completely.

7 Sunlight Discount Factor
Value used to improve the tracking
accuracy of a photocell during periods
of high daylight. Decreasing the value
will lower the controlled level of the
lights.
8 Incremental Holdback Set-Point
Adjustment
Alters the target light level for daylight
holdback in foot-candles.
11 Dual Zone Mode
Stepped Dimming (DUO)
Determines the ideal On/Off
combination of the two poles to
achieve adequate lighting
Percentage Offset
Allows Zone 2 set-point to be set as
a percentage of Zone 1 set-point
- 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.
Warning
It is the installer's responsibility to ensure that the
equipment being controlled is visible from every
control location and that only suitable equipment 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 equipment 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.
Dual Zone (LRL2385)
Provides second output that can control an
additional zone of lighting
Two Operational Modes:
Stepped Dimming (Duo): Determines the
ideal On/Off combination of the two poles to
achieve adequate lighting; best for A/B (also
called inboard/outboard) switching applications
Percentage Offset: A percentage higher than
the primary pole's set-point is used as a relative
set-point for the second pole; best for rooms
with separately controlled parallel rows of lights
18 Second Zone Off-Point
Zone 2 set-point is selected as a
percentage of Zone 1 set-point
(Only available when Percentage Offset
Mode is selected for function 11 Dual
Zone Mode)
