Outdoor Fixture High/Low Mount Sensor (continued)

Daylight Operation (closed loop)

• Daylight operation is enabled by default.

• When the measured light exceeds the calibrated level, the fixture will dim lighting to reduce the light level.

• When the measured light level exceeds 150% of the calibrated light level for more than 30 minutes, the sensor will dim to OFF.

• Lighting will be turned back ON when one of the two conditions occurs:

• The measured light level falls between 100% and 50% of the calibrated light level for more than 10 minutes.

• The measured light level falls below 50% of the calibrated light level for longer than 30 seconds.

Calibration methods supported: Auto calibration

Closed Loop Daylight Calibration Recommendations for Manual Calibration

It is recommended that the daylight sensor be calibrated at night. During the day, there is too much daylight to accurately calibrate.

For networked areas, during calibration, use the 'Calibrate All' feature and adjust slider bars to 100% to turn lighting full ON. Once all fixtures are adjusted send the 'Calibrate'

command. Standalone areas will need to perform this same calibration individually for each device.

Daylight Operation (open loop)

Daylighting will not operate until an open loop daylight set is created and configured in a networked area.

• Once configured, the controlled devices will dim in response to daylight.

• When the measured daylight contribution increases or decreases, the controlled devices will dim or raise lighting to reduce or increase the light level.

• When the measured light level exceeds 150% of the calibrated gain for more than 30 minutes, the sensor will dim to OFF.

• If lighting has dimmed to OFF and the area is still occupied, lighting will be turned back ON when one of the two conditions occurs:

• The measured light level falls between 100% and 50% of the calibrated gain for more than 10 minutes

• The measured light level falls below 50% of the calibrated gain for longer than 30 seconds

Open Loop Daylight Adjustment Recommendations

• In standard parking garage scenarios, perform calibration during daylight hours when electric lighting should be reduced but not fully dimmed. The use of a light meter is

recommended. With electric lighting turned OFF, verify with a light meter at the work surface that the reading with daylight alone is within 50% to 75% of the desired target light

level. If the light level is too high or too low, return at a time when the daylight level is within this optimal range. (For example, if the desired light level at the work surface is 500 lux,

the reading with electric lighting OFF should be between 250 to 375 lux for best results.)

• In the daylight set's 'Calibrate' screen, adjust the slider bar to change the light level to the desired light level, then tap the back button to save the change.

Factory Reset Instructions

The factory reset will unprovision the device, setting the device back to factory settings. The device will revert to out-of-the-box behavior and will need to be provisioned and

reprogrammed.

• Cycle the power (switch OFF {30 seconds} and then ON {5 seconds}) to the device's circuit six times – 6

• After a brief period, the device should exhibit out-of-the-box behavior and may be provisioned again.

Note: It is recommended to avoid placing sensors within 3ft (1m) of air vents.

Devices with older firmware may not exhibit the exact LED pattern described.

May require a firmware update for auto calibration capability.

Identification Mode Behavior

When placed in 'Blink to Identify' mode:

• The fixture will turn ON for 1 second and then turn OFF for 1 second.

• The LED in the sensor window will flash magenta for 1 second, and then turn OFF for 1 second.

• This cycle will repeat for 15 seconds.
