Best Solution
Acuity Brands Lighting & Controls provides the best solution
to achieve this for every application. Our LED luminaires are
0-10V dimmable (continuous dimming) and are standard with
embedded controls (nLight-Enabled Controls). Acuity Brands
Lighting offers three different solutions depending on your
application and budget: Architectural Best, Specification
Better, and General Purpose Good.

Lithonia Smart LED luminaires it allows
you to design and meet the above
requirement. The design to the right utilizes Lithonia RTLED
digital luminaires, which come standard with an embedded
nLight device. While the occupancy sensor controls both A
and B rows together, the Automatic Dimming Photocell and
Dual On/Off/Dim push-button WallPod (Switches) provide
each row with separate daylight harvesting and control.

REQUIREMENT:
TUNING
Tuning the ability to set a maximum light level at lower level
than full power. With nLight technology (embedded controls)
it allows you the flexibility to set a maximum light level (max.
foot-candle requirement) for any application. nLight allows
you the flexibility to set the dimming range so it is lower and
doesn’t raise to full bright or a higher light level.
Example: In a small office the light level requirement is 30 FC
but when the luminaire is at full bright the light level raises to
50 FC. We are able to tune its maximum dimming range so it
doesn’t exceed 80%, this way we can maintain 30 FC and not
exceed the maximum light level.

REQUIREMENT:
AUTOMATIC DAYLIGHTING CONTROLS
Code requires partial on/off (high/low) occupancy sensor
controls in addition to shut-off controls in: corridors,
stairwells, warehouse aisles, open areas, library book stack
aisles, per Section 130.1(c) 6.
The nLight photocell sensor provides both on/off and
automatic dimming control for daylight harvesting
applications. It monitors daylight conditions in a room, then
controls the light to ensure that adequate lighting levels are
maintained.
• Lighting power shall be reduced by at least 50% when
unoccupied
• Each warehouse aisle shall be controlled independently
REQUIREMENT:
• EXCEPTION: in warehouse aisles in which the installed
lighting power is <=80% of the value allowed under the
Area Category Method, occupant sensing controls shall
reduce lighting power by at least 40%
DEMAND RESPONSE CONTROLS
• Applies to all buildings >10,000 sq. ft.
• Lighting shall be automatically reduced in response to a
demand response signal; so that the building’s total
lighting power can be lowered by a minimum of 15%
below the maximum total lighting power
Code requires partial on/off (high/low) occupancy controls
and are required instead of shut-off controls in:
• Stairwells and common area corridors which provide
access to guestrooms and dwelling units of highrise residential buildings and hotel/motels; parking
garages, parking areas and loading and unloading areas
(130.1(c)7)

SECURITY AND EGRESS LIGHTING
• Modest allowances for egress lighting remain, but egress
lighting must be shut off outside occupied times along
with general lighting
• Only offices will be allowed to maintain 24/7 lighting, but
only along designated paths of egress, and at a reduced
maximum of just 0.05 W / ft2, (versus 0.3 W / ft2 under
the previous code)

Under the 2008 code, most buildings were allowed to keep
approximately 15% of their full-lighting capacity on at all
times for security and egress purposes. This allowance has
been either eliminated entirely or drastically reduced under
the new standards:

Best Solution
Acuity Brands Controls provides several solutions that makes
manual control of emergency lighting safely accomplished.
• LC&D’s SnapLink30A Normally Closed Latching Relays are
UL 924 listed for emergency use; upon loss of normal
power the relays will be held in the closed position. This
solution allows you to use a 100% digital lighting control
system.
• LC&D also offers Emergency Shunt Relays which are
UL 924 listed; this allows use of standard wall switches/
dimmers to control the lights locally and shunts around
wall switches, in order to turn on emergency lighting in
the event of loss of normal utility power.
• nLight offers several Emergency Relays that are
UL 924 compliant devices used to switch and dim
luminaires powered via an emergency circuit. Ideal for
use along side any nLight relay pack that controls a
space’s normal powered lighting.
PLUG LOAD CONTROLS
• In all buildings, both controlled and uncontrolled, 120V
receptacles shall be provided in each private office,
open office area, reception lobby, conference room,
kitchenette in office spaces and copy room (130.5(d))
• Controlled receptacles shall follow the automatic shut-off
requirements for lighting (130.1(c)(1-5))
• At least one controlled receptacle shall be installed
within 6 ft. of each uncontrolled receptacle
• Controlled receptacles shall have a permanent marking
to differentiate them from uncontrolled receptacles

Best Solution
Acuity Brands Controls provides several solutions that meet
the plug load controls requirements.
• LC&D’s SnapLink 30A Normally Closed Latching Relays
are UL rated for plug load 20A @ 120VAC. The lighting
control panel has inputs for occupancy sensors and
makes it easy when controlling plug loads. Perfect for
non-networked (stand-alone) and networked lighting
controls.
• Sensor Switch’s Power Pack PP20 is UL rated for plug load
20A @ 120VAC. The power packs connect to occupancy
sensors and makes it easy when controlling plug loads.
Perfect for non-networked (stand-alone) lighting control
solutions.
• nLight’s Power Packs (nPP16) are UL rated for plug load
16A @ 120VAC. The power packs connect to occupancy
sensors (Cat. 5 cable) and makes it easy when controlling
plug loads. Perfect for non-networked (stand-alone) and
networked lighting control solutions.
We can accomplish the new Title 24 requirements with Acuity Brands Controls.
