MULTI-LEVEL LIGHTING CONTROLSIn areas larger than 100 sq. ft., luminaires must have at least four steps of control, or continuous dimming, depending on the lamp type (manual dimming controls must be provided for continuous dimming luminaires). Each luminaire shall have one of the following types of controls:

• MANUAL CONTINUOUS DIMMING AND ON/OFF CONTROL per Section 130.1(a)

• LUMEN MAINTENANCE as defi ned in Section 100.1

• TUNING as defi ned in Section 100.1

• AUTOMATIC DAYLIGHTING CONTROLS per Section 130.1(d)

• DEMAND RESPONSE CONTROLS per Section 130.1(e)

Best SolutionAcuity 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, Specifi cation Better, and General Purpose Good.

REQUIREMENT: MANUAL CONTINUOUS DIMMING AND ON/OFF CONTROL

nLight “Smart but Simple” digital solution to lighting controls, plug & play (Cat. 5). When combined with 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: LUMEN MAINTENANCE

Maintains constant light output as LEDs/lamps age. Lithonia Smart LED luminaires are embedded with nLight technology utilizing the n80 option. The embedded control is factory programmed to under drive the LED luminaire to 80% of rated initial lumen output. This also reduces the input watts by starting wattage consumption at 80%. Throughout the life of the fi xture the n80 option gradually increases the input wattage and maintains constant light output as LEDs age.

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 fl exibility to set a maximum light level (max. foot-candle requirement) for any application. nLight allows you the fl exibility 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 offi ce 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.

For networked lighting control solutions, Acuity Brands Controls offers “Smart but Simple” digital solutions to lighting controls, plug & play (Cat. 5) and “Wireless.”



SECURITY AND EGRESS LIGHTING 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:

• Building areas that are not occupied 24/7 will no longer be able to leave lighting on during unoccupied periods

• Modest allowances for egress lighting remain, but egress lighting must be shut off outside occupied times along with general lighting

• Only offi ces 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)

Best SolutionAcuity 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 offi ce, open offi ce area, reception lobby, conference room, kitchenette in offi ce 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 load20A @ 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.
