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

To set the delayed-off time to 6 seconds for performing a walk test. While

Test Mode:

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.
