(b) There are no more than two interlocked lighting systems serving the space.

(c) The two lighting systems are interlocked with a non-programmable double throw switch to prevent simultaneous operation, in accordance with Section 140.6(a).

(d) If all of the above in not true, the installation fails, and all connected lighting in the space shall be counted as part of the total installed lighting power.

### NA7.7.5 Lighting Controls Installed to Earn a Power Adjustment Factor (PAF) in Accordance with Section 140.6(a)2

NA7.7.5.1 Construction Inspection for all PAFs except Institutional Tuning

Verify and document the following:

(a) Separately list all requirements for each PAF that is claimed in accordance with Sections 110.9, and 140.6(a)2, and Table 140.6-A.

(b) Verify the installation complies with all applicable requirements in accordance with Sections 110.9, and 140.6(a)2, and Table 140.6-A.

(c) If all of the above in not true for a specific PAF, the installation fails, and that specific PAF cannot be used.

(d) For lighting systems that are claiming a PAF for daylight dimming plus OFF control in accordance with Section 140.6(a)2H, the system must successfully complete the functional performance test in Section NA 7.6.1.2.1, and in addition during the Full Daylight Test the controls shall automatically turn OFF the luminaires that are receiving the daylight dimming plus OFF PAF credit.

NA7.7.5.2 Acceptance Test for Institutional Tuning

For buildings with up to seven (7) enclosed areas claiming the Institutional Tuning PAF (power adjustment factor), all areas shall be tested. For buildings with more than seven (7) areas claiming this PAF, random sampling may be done on seven of the larger enclosed areas with tuned dimming systems. If any of the areas in the sample group of seven areas fails the acceptance test, another group of seven areas must be tested. If any tested system fails, it shall be tuned until it passes the test.

##### NA7.7.5.2.1 Construction Inspection of Institutional Tuning

Prior to Functional testing, verify and document the following:

(a) The controls or the methods of controlling the maximum output of luminaires is such that the maximum light output of the controlled lighting system can be limited and that normal operation of the controlled lighting does not override the maximum light output.

(b) The controls are not readily accessible to unauthorized personnel.

##### NA7.7.5.2.2 Functional testing of Institutional Tuning

For each area to be tested, do the following:

(a) The acceptance test technician shall either observe the first seven (7) systems being successfully tuned or shall verify systems that have already been tuned using the sampling protocol described in NA7.7.6.2.

(b) If the acceptance test technician is observing the tuning of the system, the party responsible for the tuning shall certify that the remainder of the system is tuned in a similar manner.

Observation of the systems during Institutional Tuning

Step 1: Determination of maximum power or output prior to Institutional Tuning

(a) Set all lighting controls to provide maximum output of the tested system without applying the limits specified for institutional tuning.

(b) Measure the full light output at a location where the illuminance is due to the controlled lighting, or measure the power draw of the controlled lighting.

Step 2: Institutional Tuning and Post-tuning Measurement

(a) Apply the limits specified for institutional tuning to the lighting system. Do not alter any other control settings.

(b) Verify the light or power reduction after institutional tuning by measuring the light output at the same location as in Step 1 or measure the power draw of the same circuit as in Step 1.

(c) If the light output or power draw measured in Step 2(b) is 85% or less of the light output or power draw measured in Step 1(b), the system passes this test; otherwise the system fails this test.

Verification of systems already tuned

Step 1: Measurement of tuned lighting system

(a) Set all lighting controls except Institutional Tuning controls to provide maximum output of tested system. Controls set to maximum light output include but not limited to: manual dimmers, multilevel occupancy sensing, and automatic daylighting controls.

(b) Measure full light output at location where most of the illuminance is due to the controlled lighting or measure power draw of the controlled lighting.

Step 2: Measurement of lighting system with Institutional Tuning overriden

(a) Reset Institutional Tuning controls to allow full light output. Set all lighting controls to provide maximum output of tested system including but not limited to: Institution Tuning control, manual dimmers, multilevel occupancy sensing, and automatic daylighting controls.

(b) Measure full light output at the same location as in Step 1 or measure the power draw of the same circuit as in Step 1.

(c) If the light output or power draw measured in Step 1(b) is 85% or less of the light output or power draw measured in Step 2(b), the system passes this test; otherwise the system fails this test.

Step 3: Restore Institutional Tuning settings

(a) If tested system passed the test in Step 2, restore Institutional Tuning settings.

### NA7.7.6 Lighting for a Videoconferencing Studio in Accordance with Exception to Section 140.6(a)3T
