C408.3 Lighting System Functional Testing
Where occupant sensor controls are provided, the following procedures shall be performed:
- Certify that the occupant sensor has been located and aimed in accordance with manufacturer recommendations.
- For projects with seven or fewer occupant sensors, each sensor shall be tested.
For projects with more than seven occupant sensors, testing shall be done for each unique combination of sensor type and space geometry. Where multiples of each unique combination of sensor type and space geometry are provided, not less than 10 percent, but in no case less than one, of each combination shall be tested unless the code official or design professional requires a higher percentage to be tested. Where 30 percent or more of the tested controls fail, all remaining identical combinations shall be tested.
For occupant sensor controls to be tested, verify the following:
- 3.1. Where occupant sensor controls include status indicators, verify correct operation.
- 3.2. The controlled lights turn off or down to the permitted level within the required time.
- 3.3. For auto-on occupant sensor controls, the lights turn on to the permitted level when an occupant enters the space.
- 3.4. For manual-on occupant sensor controls, the lights turn on only when manually activated.
- 3.5. The lights are not incorrectly turned on by movement in adjacent areas or by HVAC operation.
Where time-switch controls are provided, the following procedures shall be performed:
- Confirm that the time-switch control is programmed with accurate weekday, weekend and holiday schedules.
- Provide documentation to the owner of time-switch controls programming including weekday, weekend, holiday schedules, and set-up and preference program settings.
- Verify the correct time and date in the time switch.
- Verify that any battery back-up is installed and energized.
- Verify that the override time limit is set to not more than 2 hours.
Simulate occupied condition. Verify and document the following:
- 6.1. All lights can be turned on and off by their respective area control switch.
- 6.2. The switch only operates lighting in the enclosed space in which the switch is located.
Simulate unoccupied condition. Verify and document the following:
- 7.1. Nonexempt lighting turns off.
- 7.2. Manual override switch allows only the lights in the enclosed space where the override switch is located to turn on or remain on until the next scheduled shutoff occurs.
- Additional testing as specified by the registered design professional.
Where daylight responsive controls are provided, the following shall be verified:
- Control devices have been properly located, field calibrated and set for accurate setpoints and threshold light levels.
- Daylight controlled lighting loads adjust to light level set points in response to available daylight.
- The locations of calibration adjustment equipment are readily accessible only to authorized personnel.
