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.” |
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.
