Vacancy Sensor Requirements
for Title 20-2012
(Manual-On Occupant Sensor)
All occupant sensing devices shall:
- be capable of automatically turning off all
controlled lights in the area no more than
30 minutes after the area has been vacated;
- allow all lights to be manually turned off
regardless of the status of occupancy; and
- 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
off the signal.
Vacancy sensors shall:
- not turn on lighting automatically;
- and shall not incorporate DIP switches,
or other manual means, for conversion
between manual and automatic functionality;
- have a grace period of no more than 30
seconds and no less than 15 seconds to
turn on lighting automatically after the
sensor has timed out; and
- not have an override switch that disables
the sensor.
Note: Subject to change when final version T20-2012 is published.
INTRODUCTION
The California Energy Commission recently adopted changes
to Title 20 of the California Code of Regulations that have
added requirements for self-contained lighting controls
such as occupancy sensors, dimmers and programmable
timers to be certified to the Commission and listed in the
Title 20 Appliance Database. California Title 20-2012 (T20) is
the product efficiency regulation and will become effective
on Feb 1, 2013. Any product falling within the scope of T20 will
need to meet the requirements to be legally sold in California.
The newly adopted regulation contains much of the same
lighting control specific requirements currently in the existing
building energy regulation CA Title 24-2008.
CA Title 24-2008 is the current building energy regulation.
Section 119 of this regulation contains similar specific require-
ments for lighting controls installed in commercial and residen-
tial buildings. These specific requirements will simply reference
T20 in the upcoming Title 24-2013 edition which goes into
effect in 2014. Title 24-2013 also proposes changes to the
definition of major renovation. Self-contained Lighting Controls
will need to meet requirements of both Title 20 and Title 24
to be installed in new construction and most renovation.
LEVITON SOLUTIONS
Leviton has a line of vacancy sensors which comply with
California Title 20-2011 and Title 24-2008 / 2012 lighting
control requirements.
The IPV05, IPVD6 and IPV15 California Title 24 compliant
vacancy sensors feature Manual-ON and Automatic-OFF
operation and offer 180° field of view, 900 sq. ft. coverage
for optimal motion detection. All models offer an adjustable
delayed OFF functionality which can be set for 30 seconds,
5 minutes, 15 minutes or 30 minutes for effective energy
management. The devices fit in a standard wallbox; the low
profile design blends in with walls for a discreet appearance.
In order to meet Title 24 requirements, the proper lighting
technology, or combination of technologies, must be utilized.
For residential buildings, the use of high-efficacy luminaires
is preferred over low-efficacy luminaires paired with lighting
controls. High-efficacy luminaires are designed and built to
operate only energy-efficient light sources such as LEDs, CFLs
and fluorescent lighting systems. Low-efficacy luminaires are
generally incandescent and halogen systems and, in order to
be Title 24 compliant, must be paired with lighting controls
such as dimmers or vacancy sensors.
