DESCRIPTION
The Occupancy Sensor is a low-voltage infrared sensor that works with the LPCS Series
power pack to automatically control lighting. The sensor turns the lights on and keeps
them on whenever occupancy is detected and will turn them off after the ‘delayed-off
time’ has expired.
The sensor continually analyzes and adjusts to changing conditions. The sensor uses
the latest microprocessor-based technology which permits it to continually adjust and
optimize its performance.
Infrared motion detection gives higher false triggering immunity that yields a sensor with
excellent performance.

DI-400-OSC15-00A-X1
OPERATION
Motion detection by the infrared sensor will turn on the lights as well as keeping them
on. When motion is not detected, the lights will turn off after the delayed-off time.
•Delayed-Off time – The sensor is designed to turn the lights off if no motion is
detected after a specified time. This length of time is called the delayed-off time and
is set using the timer (Black) knob on the sensor. The adapting patterns will modify
the delayed-off time to fit the parameters of each installation based on
environmental conditions and occupancy patterns.
•Walk-through Mode – The walk-through feature is useful when a room is
momentarily occupied. With this feature, the sensor will turn the lights off shortly
after the person leaves the room.
The walk-through feature works as follows: When a person enters the room, the
lights will turn on. If the person leaves the room before the default walk-through time-
out of 2.5 minutes, the sensor will turn the lights off. If the person stays in the room
for longer than 2.5 minutes, the sensor will proceed to the standard operation.
•LED Operation – There are two LED indicators that will flash when motion is
detected. The LED flash can be disabled using the LED disable switch setting. Red
flash indicates motion detection by infrared technology.
ADAPTIVE FUNCTIONS
The Sensor continually analyzes the parameters of the motion detection signal and
adjusts its internal operation to maximize detection of motion while minimizing the
effects of noise (electrical noise, air currents, temperature changes, etc…).
Operation:
When the lights turn on, the sensor initially enters the “walk-through” mode. Once the
room is occupied for longer than 2.5 minutes, the sensor exits the “walk-through” mode
and enters the “Occupied” mode. When the sensor is first installed, the delayed-off
time for the occupied mode is based on the Time adjustment settings. While the sensor
is in use, the delayed-off time will change, based on how the sensor adapts to the room
conditions. Whenever the sensor subsequently turns on, the value of the delayed-off
time will be the
adapted value (refer to Occupancy Pattern Learning For Delayed
Off Time).
The adapted settings can be reset using the DIP switch.
Occupancy Pattern Learning For Delayed Off Time:
The sensor will automatically change the delayed off time in response to the occupancy
and environmental conditions of the space it is installed in. The sensor analyzes the
motion signal properties and will minimize the delayed off time duration when there is
frequent motion detection, and lengthen the delayed off time duration when there is
weak and infrequent motion detection.
In the case of a false-off condition (lights turn off when the room is occupied), the
delayed off time duration will immediately be lengthened to prevent further false turn
offs.
Occupancy Pattern Learning for Infrared Technology:
The sensor learns the occupancy patterns of a space during the course of a day, for a
seven day period. At any given time, the sensor will look at the collected data and
adjust its infrared sensitivity. The sensor will adjust the sensitivity to make it less likely
to turn on during a period of non-occupancy and more likely to turn on during a period
of occupancy.
SETTINGS
Default Settings:
Adjustment knob settings as per “recommended manual settings,” (refer to Table 2
and Figure 1).
All switches in the off position (refer to Table 3).
Test Mode: To set the delayed-off time to 6 seconds for performing a walk test. While
the sensor is in test mode, the LED’s will flash amber once every 4 seconds.
NOTE: After entering test mode, the seven-day collected data will be erased.
1. ENSURE POWER IS ON.
2. Remove front cover.
3. Locate Dip Switch 3 in Bank B (B3) (refer to Figure 1). B3 will be in the OFF
position from the factory.
4. To enter Test Mode, move switch to ON and back to OFF. The test mode has now
been entered with a 6 second time-out. NOTE: If B3 is already in the ON position,
then test mode can be entered by just moving it to the OFF position.
NOTES:
1. The timer will remain in the 6 second test mode for 15 minutes, then automatically
exit test mode and reset to the delayed-off time setting as defined by the black timer
knob.
2. To manually take the timer out of the 6 second test mode, simply toggle the switch
B3 from OFF to ON and back to OFF.
Photocell (Ambient Light Override) adjustment:
In order to use the Ambient Light Override functionality of the sensor, the sensor must
be wired to the LPCS power pack using the gray wire instead of the blue wire. This
feature allows the user to conserve energy by keeping the controlled lights off when not
necessary. The sensor does this by measuring the amount of ambient light in the
installed area and keeping the controlled lights off if there is enough ambient light
available. To use this feature, the Photocell adjustment (blue) knob must be adjusted
from the default position. Once this adjustment is made, the controlled lights will only
turn on if the ambient light present is less than the setting.
To set the Photocell level (used with the gray wire connection):
NOTE: This setting must be performed when the natural light is low enough to require
artificial light.
1. Remove the cover from the sensor.
2. Make note of the position of the Red knob. Rotate the Red knob full CCW and enter
the sensor’s Test mode as described above.
3. Rotate the Blue knob full CCW.
4. Wait for the lights to turn OFF.
5. Rotate the Red knob full CW.
6. Slowly rotate the blue knob clockwise until the lights turn ON. This is the correct setting.
7. Return the Red knob to its original position.
8. Replace cover. Setting is complete.

TROUBLESHOOTING
•Lights do not turn ON
- Circuit breaker or fuse has tripped.
- Low-voltage miswired. To Test: Connect RED to BLUE wire at power pack to force
lights ON.
- Line voltage miswired. To Test: Connect BLUE to BLUE relay wires (of power pack)
to force the lights ON.
•Lights stay ON
- Constant motion. To Test: Reduce RED knob by 15%; remove motion source. If
unsatisfactory, move sensor.
- Infrared sensor can "see" into hallway. To Test: Put sensor in timer test mode
and walk hallway. If lights continue to come ON, move sensor.
•Light turns ON too long
- Timer setting too high. To Test: Check switch settings. Typical setting is 10 minutes.
