ALL OCCUPANCIES—MANDATORY REQUIREMENTS FOR THE MANUFACTURE, CONSTRUCTION AND INSTALLATION OF SYSTEMS,

EQUIPMENT AND BUILDING COMPONENTS

Lighting controls may be individual devices or systems consisting of two or more components. (b) All lighting controls. Lighting controls listed in Section 110.9(b) shall comply with the requirements listed below; and all components of the system considered together as installed shall meet all applicable requirements for the application for which they are installed as required in Sections 130.0 through 130.5, Sections 140.6 through 140.8, Section 141.0, and Section 150.0(k).
Time-switch lighting controls. All controls that provide time-switch functionality, including all automatic and astronomical time-switch controls, shall have program backup capabilities that prevent the loss of the device’s schedule for at least 7 days, and the device’s date and time for at least 72 hours if power is interrupted. In addition: A. Time-switch controls installed in nonresidential

buildings shall:

i. For each connected load, be capable of providing manual override to each connected load and of resuming normally scheduled operation after a manual override is initiated within 2 hours; and

ii. Provide an automatic holiday shutoff feature

that turns off all connected loads for at least 24 hours and then resumes normally scheduled operation. B. Astronomical time-switch controls shall:

i. Have sunrise and sunset prediction accuracy

within plus-or-minus 15 minutes and timekeeping accuracy within 5 minutes per year;

ii. Be capable of displaying date, current time,

sunrise time, sunset time, and switching times for each step during programming;

iii. Be capable of automatically adjusting for

daylight savings time; and

iv. Have the ability to independently offset the

C. Provide a linear response within 5 percent accu racy over the range of illuminance measured by the light sensor; and

D. Be capable of being calibrated in a manner that

the person initiating the calibration is remote from the sensor during calibration to avoid influencing calibration accuracy, for example by having a light sensor that is physically separated from where the calibration adjustments are made.

Dimmers. Controls that provide dimming functionality shall:

A. Be capable of reducing lighting power consump tion by a minimum of 65 percent when at its lowest setting;

B. Provide reduced flicker operation, meaning that

directly controlled light sources shall be provided electrical power such that the light output has an amplitude modulation of less than 30 percent for frequencies less than 200 Hz without causing premature lamp failure;

C. Provide an off setting that produces a zero lumen

output; and

D. For wall box dimmers and associated switches

designed for use in three way circuits, be capable of turning lights off, and on to the level set by the dimmer if the lights are off.

Occupant sensing controls. Occupant sensing controls include occupant sensors, motion sensors, and vacancy sensors, including those with a partial-ON or partialOFF function. Occupant sensing controls shall:

A. Be capable of automatically turning the con trolled lights in the area either off or down no more than 20 minutes after the area has been vacated;

B. For manual-on controls, have a grace period of

no less than 15 seconds and no more than 30 seconds to turn on lighting automatically after the sensor has timed out; and

C. Provide a visible status signal that indicates that

the device is operating properly, or that it has failed or malfunctioned. The visible status signal may have an override that turns off the signal.

Exception to Section 110.9(b)4: Occupant sensing control systems may consist of a combination of single or multilevel occupant, motion or vacancy sensor controls, provided that components installed to comply with manual-on requirements shall not be capable of conversion by occupants from manual-on to automatic-on functionality.

Reserved.
Sensors used to detect occupants. Sensors that are used by occupant sensing controls to detect occupants shall meet all of the following requirements:

on and off for each channel by at least 90 minutes before and after sunrise or sunset. C. Multilevel time-switch controls shall include at

least two separately programmable steps per zone.

D. Time-switch controls installed outdoors shall

have setback functions that allow the lighting on each controlled channel to be switched or dimmed to lower levels. The set back functions shall be capable of being programmed by the user for at least one specific time of day.

Daylighting controls. Controls that provide automatic daylighting functionality shall:

A. Automatically return to its most recent time delay

settings within 60 minutes of the last received input when left in calibration mode;

B. Have a set point control that easily distinguishes

settings to within 10 percent of full-scale adjustment;

ALL OCCUPANCIES—MANDATORY REQUIREMENTS FOR THE MANUFACTURE, CONSTRUCTION AND INSTALLATION OF SYSTEMS, EQUIPMENT AND BUILDING COMPONENTS

A. Sensors shall not incorporate switches or

mechanical devices that allow the sensor to be disabled without changing the settings of the control.

B. Sensors that utilize ultrasonic radiation for detec tion of occupants shall:

i. comply with 21 C.F.R. part 1002.12;

ii. not emit audible sound; and

iii. not emit ultrasound in excess of the deci bel levels shown in Table 110.9-A measured no more than 5 feet from the source, on axis.

C. Sensors that utilize microwave radiation for

detection of occupants shall:

i. comply with 47 C.F.R. parts 2 and 15;

and

ii. not emit radiation in excess of 1 milliwatt

per square centimeter measured at no more than 5 centimeters from the emission surface of the device.

Indicator lights. Indicator lights integral to lighting controls shall consume no more than 1 watt of power per indicator light. (c) Track lighting integral current limiter. An integral current limiter for line-voltage track lighting shall be recognized for compliance with Part 6 only if it meets all of the following requirements:
Shall have the identical volt-ampere (VA) rating of the current limiter as installed and rated for compliance with Part 6 clearly marked as follows:

A. So that it is visible for the enforcement agency’s

field inspection without opening coverplates, fixtures or panels; and

B. Permanently marked on the circuit breaker; and

C. On a factory-printed label that is permanently

affixed to a nonremovable base-plate inside the wiring compartment.

Shall have a conspicuous factory installed label permanently affixed to the inside of the wiring compartment warning against removing, tampering with, rewiring or bypassing the device; and
Each electrical panel from which track lighting integral current limiters are energized shall have a factory printed label permanently affixed and prominently located, stating the following: “NOTICE: Current limiting devices installed in track lighting integral current limiters connected to this panel shall only be replaced with the same or lower amperage. Adding track or replacement of existing current limiters with higher continuous ampere rating will void the track lighting integral current limiter certification, and will require resubmittal of compliance documentation to the enforcement agency responsible for compliance with the California Title 24, Part 6 Building Energy Efficiency Standards.”

(d) Track lighting supplementary overcurrent protec- tion panel. A Track Lighting Supplementary Overcurrent Protection Panel shall be used only for line-voltage track lighting and shall be recognized for compliance with Part 6 only if it meets all of the following requirements:

Shall be listed as defined in Section 100.1; and
Shall have a permanently installed label that is prominently located stating the following: “NOTICE: This Panel for Track Lighting Energy Code Compliance Only.” The overcurrent protection devices in this panel shall only be replaced with the same or lower amperage. No other overcurrent protective device shall be added to this panel. Adding to, or replacement of, existing overcurrent protective device(s) with higher continuous ampere rating will void the panel listing and require resubmittal of compliance documentation to the enforcement agency responsible for compliance with the California Title 24, Part 6 Building Energy Efficiency Standards.
