A22.214.171.124 Occupant Sensors, Motion Sensors and Vacancy Sensors
JUMP TO FULL CODE CHAPTER
Occupant sensors, motion sensors and vacancy sensors shall be capable of automatically turning off all the lights in an area no more than 30 minutes after the area has been vacated and shall have 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 switch that turns the signal off. In addition, ultrasonic and microwave devices shall have a built-in mechanism that allows calibration of the sensitivity of the device to room movement in order to reduce the false sensing of occupants and shall comply with either Subsection A126.96.36.199.1 or A188.8.131.52.2 below, as applicable:
If the device emits ultrasonic radiation as a signal for sensing occupants within an area, the device shall:
- Have had a Radiation Safety Abbreviated Report submitted to the Center for Devices and Radiological Health, Federal Food and Drug Administration, under 21 Code of Federal Regulations, Section 1002.12 (1996) and a copy of the report shall have been submitted to the California Energy Commission; and
- Emit no audible sound; and
- Not emit ultrasound in excess of the decibel (dB) values shown in Table A5.209.1-A, measured no more than 5 feet from the source, on axis.
If the device emits microwave radiation as a signal for sensing occupants within the area, the device shall:
- Comply with all applicable provisions in 47 Code of Federal Regulations, Parts 2 and 15 (1996) and have an approved Federal Communications Commission Identifier that appears on all units of the device and that has been submitted to the California Energy Commission; and
- 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; and
- Have permanently affixed to it installation instructions recommending that it be installed at least 12 inches from any area normally used by room occupants.
