## 13.27. NA7.8 Outdoor Lighting Shut-off Controls

At-A-Glance

NA7.8 Outdoor Lighting Shut-off Controls
Use Document NRCA-LTO-02-A
Purpose of the Test
The purpose of these tests is to ensure that all outdoor lighting regulated by §130.2(c) are automatically turned off during daytime and are controlled by a motion sensor, photocontrol, astronomical time-switch control, part-night outdoor lighting control or automatic scheduling control, as required. Automated controls to turn off outdoor lighting during daytime hours, and when not needed during nighttime hours, prevent energy waste.
Instrumentation
This test verifies the functionality of installed automatic controls visually and does not require special instrumentation.
Test Conditions
All outdoor luminaires must be wired and powered.
Lighting control system must be installed and ready for system operation, including completion of all start-up procedures, per manufacturer’s recommendations.
Estimated Time to Complete
Construction Inspection: 0.5 to 2 hours (depending on familiarity with lighting control programming language)
Equipment Test: 0.5 to 2 hours (depending on familiarity with lighting control programming language, number of lighting circuits to be tested)
Acceptance Criteria
Lights turn off when daylight is available.
Automatic time switch controls turn off the lighting when not needed at night Motion sensors reduce lighting power by at least 40 percent but not exceeding 90 percent.
The correct date and time are properly set in the lighting controllers.
Astronomical time switch controls and automatic time switch controls have been certified to the Energy Commission in accordance with the applicable provision in §110.9. Verify that model numbers of all such controls are listed on the Energy Commission database as “Certified Appliances & Control Devices.” http://www.energy.ca.gov/appliances/database/

A. Test Application

Newly Constructed and Additions/Alterations: Applies to functional testing and verification of motion sensor location and ensures the sensor coverage is not blocked by obstruction.

• Verifies the sensor signal sensitivity is adequate.

• Verifies the outdoor lighting shut-off control during daytime hours.

• Verifies the astronomical and standard shutoff controls are programmed for weekdays, weekends and holiday schedules.

NA7.8.1 – and NA 7.8.2 Motion Sensor

The motion sensor must be installed in conjunction with a photocontrol or astronomical time switch that automatically turns off the outdoor lighting when daylight is available.

Prepare for allowable sampling:

• For buildings with up to seven (7) outdoor motion sensors, all outdoor motion sensors shall be tested.

• For buildings with more than seven (7) outdoor motion sensors for outdoor lighting system, sampling may be done on outdoor areas with similar sensors that cover similar unobstructed areas.

o Sampling shall include a minimum of 1 outdoor motion sensor for each group of up to 7 additional outdoor motion sensors.

o If the first sensor in the sample group passes the acceptance test, the remaining outdoor areas in the sample group also pass.

o If the first sensor in the sample group fails the acceptance test, the rest of the sensors in that group shall be tested.

• Any failed sensor in the sample group shall be repaired or replaced and retested until the sensor passes the test.

B. Construction Inspection

Prior to Functional testing, verify and document:

• Motion sensor has been located to minimize false signals.

• Sensor is not triggered by motion outside of adjacent area. Desired motion sensor coverage is not blocked by obstruction that could adversely affect performance.

• Desired sensor coverage is not blocked by obstructions that could adversely affect performance.

C. Functional Testing

Test conditions: Simulate or provide conditions so that outdoor photocontrol or astronomical time switch is in night time mode and is otherwise turning lights ON.

Simulate motion in area under lights controlled by the sensor.

Verify and document

Status indicator operates correctly.

Lights controlled by motion sensors turn on immediately upon entry into the area lit by the controlled lights near the motion sensor.

Signal sensitivity is adequate to achieve desired control.

Simulate no motion in area with lighting controlled by the sensor.

Verify and document

Lights controlled by motion sensors turn off within a maximum of 20 minutes from the start of an unoccupied condition per §110.9(b).

The occupant sensor does not trigger a false “on” from movement outside of the controlled area.

Signal sensitivity is adequate to achieve desired control.

NA 7.8.3 and NA 7.8.4 Photocontrol

B. Construction Inspection

Verify and document:

• The photocontrol is installed.

C. Functional Testing

Verify and document:

• During daytime simulation, all controlled outdoor lights are turned off.

• During nighttime simulation, all controlled outdoor lights are turned on.

NA7.8.5 and NA 7.8.6 Astronomical Time-Switch Control

B. Construction Inspection

Prior to Functional Testing, confirm and document:

• Verify the astronomical time-switch control is installed.

• Verify the astronomical time switch control is programmed with acceptable ON schedule and OFF schedule

• Demonstrate and document for the time switch programming including ON schedule and OFF schedule, for weekday, weekend, and holidays (if applicable).

• Verify the correct time and date is properly set in the control.

C. Functional Testing

Verify and document:

• During daytime simulation, all controlled outdoor lights are turned off.

• During nighttime simulation, all controlled outdoor lights are turned on in accordance with the astronomical schedule.

• During nighttime simulation, all controlled outdoor lights are turned off in accordance with the programmed schedule.

NA7.8.7 and NA 7.8.8 Part-night Outdoor Lighting Control

Note: The part-night outdoor lighting control must be installed in conjunction with a photocontrol or astronomical time switch that automatically turns off the outdoor lighting when daylight is available.

B. Construction Inspection

Prior to Functional Testing for time based control type, confirm and document:

• Verify the part-night outdoor lighting control is installed.

• Verify the control is programmed with acceptable schedules.

• Demonstrate and document for the lighting control programming including both ON schedule and OFF schedule, for weekday, weekend, and holidays (if applicable).

• Verify the correct time and date is properly set in the control.

Prior to Functional Testing for occupancy-based control type, verify and document:

• Sensor has been located to minimize false signals.

• Sensor is not triggered by motion outside of adjacent area.

• Desired sensor coverage is not blocked by obstructions that could adversely affect performance.

C. Functional Testing

For time-based control type, verify and document:

• During daytime simulation, all controlled outdoor lights are turned off.

• During nighttime simulation, all controlled outdoor lights are turned on in accordance with the ON schedule.

• During nighttime simulation, all controlled outdoor lights are turned off or reduced in light level in accordance with the OFF schedule.

For occupancy-based control type, verify and document:

Step 1: Simulate motion in area under lights controlled by the sensor. Verify and document the following:
