Installation Instructions - Quadcast LED Occupancy Sensor (QDOCC)
DESCRIPTION AND OPERATIONe:
The occupancy sensor has an integral photocontrol that turns lighting ON and OFF based on occupancy and ambient light
levels. The sensors use passive infrared (PIR) sensing technology that reacts to changes in infrared energy (moving body heat)
within the coverage area. Once the space is vacant and the time delay elapses (adjustable from 30 seconds to 30 minutes),
lights will turn OFF .
INSTALLATION
Important, there is an initial warm-up period:
It may take up to a minute before the lights turn ON due to
a sensor warm-up period required during initial
power-up. This occurs during installation or after a lengthy
power failure only. (Figure1.)
Light Level Feature
The Light Level photocontrol feature holds OFF and turns
OFF lights when the space is occupied and adequate
ambient light exists. When the light level drops below
the set level it will turn the lights ON when the space is
occupied. The factory setting is for maximum, meaning that
even bright ambient light will not cause the sensor to hold
the lights OFF if it detects occupancy in the controlled area.
(Figure 2.)
Sensor Adjustment
The Light Level and Time Delay adjustment trimpots
are located under the lens assembly. The trimpots are
accessed easily after the sensor is mounted in the fixture.
Gently unscrew the lens assembly. Do not remove the
thumbscrew collar, it holds the sensor in place on the
fixture. Identify each trimpot. Set the light level when the
controlled light would normally be turned OFF due to the
presence of sufficient daylight or other electric light. [If this
feature is not needed, leave the light level at maximum (fully
clockwise)].
*.At the maximum setting, the light level entering the
photosensor must exceed 120 Fc, which only happens in
rare applications or when the lens is removed. (Figure 2.)
Test Occupancy Sensor (Optional)
1.
Set Light Level to maximum (fully clockwise,
factory setting) and Time Delay to minimum (fully
counterclockwise). Put the lens assembly back onto the
sensor.
2.
Move out of the sensor's view. Lights turn OFF after 30
seconds.
DO NOT OVERTURN TRIMPOT WHEN ADJUSTING THE SENSOR.
DO NOT TOUCH THE SQUARE INFRARED DETECTOR
UNDER THE LENS ASSEMBLY.

Move into the controlled area. The red LED in the
sensor lens should illuminate and the lights should turn
ON.
Test and Adjust Light Level Photocontrol Sensor and
Time Delay (Figure 3.)
1.
Remove the lens assembly and adjust the light level
and the time delay to minimum. Put the lens assembly
back onto the sensor. Leave the controlled area and let
the sensor time out so lights are OFF .
2.
Enter the controlled area and lights should remain OFF .
3.
Make sure your body does not cast a shadow on the
sensor. Turn the light level trimpot clockwise in small
increments. After each adjustment, put the lens back
on the sensor then move about the controlled area.
Wait 5-10 seconds to see if the lights turn ON.
4.
Continue this procedure until the lights turn ON. At this
setting the lights will not turn ON with occupancy if the
light level is above the current level.
5.
Set the time delay to the desired setting. The
time delay can be set from 30 seconds (fully
counterclockwise) to 30 minutes (fully clockwise).
