Commercial Lighting DALI Edition Design Guide
Introduction
Digital Addressable Lighting Interface (DALI®) systems should be used where ballast level control is required.
DALI is ideal for open space commercial environments. When cubicle and workspace layouts change, the
lighting can be regrouped and adjusted as needed. Other typical applications include college lecture halls, hospital
operating rooms, and corporate conference rooms. DALI provides tremendous flexibility for both retrofit and new
installations. When replacing lamps and ballasts on a DALI system, the wiring stays the same and the DIN-DALI-2
readdresses the new ballast with the address and parameters of the original ballast.
Crestron® control systems seamlessly connect with the open DALI protocol by way of the DIN-DALI-2 interface. The
DIN-DALI-2 interface can work with any Crestron control system as well as any power supply. Crestron devices
such as keypads, thermostats, photo and occupancy sensors, gateways, and other Cresnet® devices can easily
communicate with the DALI system.
Commissioning lighting groups, detecting faults, and replacing ballasts is simple when using the powerful Crestron
DALI Commissioning Tool. The user can develop interactive floor plans using Smart Graphics™, which provides
easier monitoring, management, and control of all the light fixtures within the space.
Crestron delivers the most comprehensive DALI ballast solution with 1-, 2-, and 3-lamp versions available for
any application, in any part of the world. Crestron Green Light® DALI ballasts support dimming a wide range of
fluorescent lamps from 1 to 100%. DALI ballasts are the most comprehensive ballast solution on the market today.
The DALI ballasts drive multiple lamp wattages in one unit, which makes lighting design easier and less expensive.
The new line of Crestron dimmable LED drivers provides high-power LED lighting with deep dimming to below 1%.
Available in 50 W and 100 W models with DALI control, GLD-LED drivers offer superior, smooth dimming technology
using a combination of duty-cycle and current dimming.
The optional built-in power metering feature is unique to Crestron DALI ballasts. The ability to measure, monitor,
and manage power to each light fixture, while enabling daylight harvesting and load shedding, makes it easy to
implement a fully-integrated system that combines architectural lighting control and energy management all on
one platform. Optional power metering models track real-time energy usage of each load and provide essential
statistics to help manage and control utility costs.
Refer to the Lighting Control webpage on the Crestron website for more information on DALI ballasts and drivers.

SECURITY
SYSTEM
DALI is a protocol used for the direct control of lighting ballasts. The DALI standard allows multiple ballasts to be
daisy-chained using low-voltage wiring for power on/off and dimming control. Up to 64 independently operating
ballasts can exist on a single DALI channel. DALI lighting is optimal for applications that require granular control of
each fixture, such as open office floor plans and daylight harvesting in classrooms.
Control wires are topology free (up to 64 between each ballast), making wiring simpler than in 0 to 10 V dimming
systems. DALI systems can report lamp and ballast failure for easier maintenance and, with Crestron PM
ballasts, controllers can query energy usage. Additionally, the DALI data is resistant to noise, which allows it to
run alongside line-voltage power lines. The Crestron DALI Commissioning Tool simplifies system installation and
provides a setup wizard with step-by-step configuration of ballast properties, groups, and scenes.
Spaces with changing tenants and large campuses with frequently repurposed rooms are the prime target of DALI
systems. Some of the key features are as follows:
2
•
Individual Addresses: Each DALI ballast has its own unique address on the system; therefore, the
system is able to communicate with each ballast independently of the others.
•
Number of Addresses: Up to 64 addresses can be on one DALI loop. An unlimited number of loops can
be placed on a complete DALI networked system.
•
Grouping: DALI ballasts can be assigned to 1 to 16 groups on a loop, without the need for rewiring.
•
Bi-directional Communication: Ballasts are able to receive information as well as report lamp or ballast
failures to the central DALI system.
Doc. 7386E | crestron.com
Commercial Lighting DALI Edition Design Guide
•
Readdressing Ballasts: If a ballast fails on a system, the loop can detect the missing address and
readdress it when a new ballast is added back in its place.
•
Warranty and Compliance: Crestron DALI ballasts include a 5 year warranty. The ballasts are UL® Listed,
CE marked, and RoHS Compliant®.
DALI Requirements
The intent of the DALI protocol is to supply low cost, interchangeable ballasts that are simple to program and
commission. DALI requirements are shown below:
•
Ballast Power Requirements: Ballasts must provide universal voltage (115 to 300 V), 50 to 60 Hz, high
power factor, low harmonics, and transient surge protection. When the initial voltage is applied, the lamps
go to full on or to a preset level.
•
Command Requirements: Ballasts are able to receive information and report this information back to
the central DALI system regarding lamp or ballast failures.
•
Lamp Response Requirements: DALI protocol requires a precise logarithmic dimming curve of 254
steps (2.8% increase per step) so that all ballasts dim the same: 0 to 100% for incandescent and
fluorescent, 3 to 100% for compact fluorescent, and 0 to 100% for LED.
•
Protocol Requirements: The DALI protocol requirements include the intent and electrical requirements
of the protocol, bits and bytes requirements, collision detection, and the type of wire to be used for the
DALI system.

Emergency and DALI Ballasts
Crestron provides cold-start emergency ballasts to illuminate rooms with existing lights during a blackout,
eliminating the need for an emergency generator.
The emergency ballast fits into the fixture with the DALI ballast. When a power outage is detected, the emergency
ballast lights up one or two lamps in the fixture for more than 90 minutes. This complies with many state and local
codes, including the National Electrical Code® and the Life Safety Code® (NFPA 101).
In the example below, five of the six fixtures are without power. One of the fixtures utilizes the emergency backup
to illuminate the room. This emergency ballast-powering scenario tremendously reduces wiring costs.

DALI Control Cable
The DALI standard does not require shielded wire. However, unshielded wire may be subject to induced voltage
degradation and interference. Crestron recommends using shielded cable because if unshielded DALI cable is
used and improperly installed, signal failures may occur. DALI control wire is sized appropriately based upon
voltage drop due to cable length. Crestron recommends 16 to 22 AWG based upon cable length. The DALI protocol
standard can communicate up to 980 ft (300 m). Per the NEC, class 1 DALI control cable may be run in the same
conduit as line voltage wire.

DALI Application Examples
The examples in this section show how a DALI control system can be utilized in an individual office, open office,
conference room, and training room.
Individual Office
By controlling the lighting fixtures with the DALI control system, daylight harvesting and room occupancy sensing
can be easily achieved by adding sensors.
In the individual office example below, the fixture closer to the window is dimmed lower than the one further from
the window based on the amount of natural light. The photo sensor measures the outdoor light while the
occupancy sensor determines if the room is in use. The Cameo keypad provides the user with control of preset
lighting scenes and dimmer control.

Training Room
Each light fixture is powered directly from the grid with each row of lights controlled by a separate channel on the
DALI control system. One channel dims the row closest to the windows while the second channel dims the other
row. Both a photocell and occupancy sensor are connected to the DALI control system for energy savings.
The example below shows how a DALI control system can be utilized in a training room setting.

Glossary of Terms
Ballast: An electrical device required in fluorescent and high intensity discharge (HID) fixtures that furnish the
necessary voltage, current, and waveform for starting and operating the lamp(s). In the United Kingdom, it is
sometimes referred to as a choke or control gear.
Current: The electrical rate of flow expressed in amperes—similar to the water flow rate in a pipe (gal/min).
Dimming ballast: A device used to obtain the conditions (voltage, current, and waveform) for starting and
operating the lamp(s) while providing variable light output such as dimming fluorescent lamp source(s). It must be
matched to the lamp type, voltage, and quantity. It is also available, with less capability, for HID sources.
Emergency lighting: When the normal power supply fails, emergency lighting is the illumination that automatically
lights the path towards the exit location(s). It may also serve to satisfy life safety and security lighting requirements.
Fade delay: The time interval between the selection of a new light intensity for a particular lighting zone and the
beginning of that zone’s change to the new level.
Fade time: The total time it takes a dimmer to change lighting from one level to another.
LED driver: A self-contained power supply that has outputs matched to the electrical characteristics of the LED or
array of LEDs.
Line voltage: The standard 120 V power provided by receptacles and for lighting fixtures in commercial spaces; it
might refer to 277 V power feed for fluorescent fixtures.
Occupancy sensor: A sensor that works with certain Crestron lighting systems to save energy and increase
convenience by automatically turning lights on when a space is occupied and off when a space is vacant.
Photosensor: A control agent for fixtures that can automate light levels. Some photosensors qualify controls for
certain rebates and incentives.
Scene: The lighting effect achieved by adjusting one or more zones of lighting to the desired intensity.
Self-ballasted lamps: A fluorescent or discharge lamp that has an integral ballast.
UL Listed: A product adhering to the standards of Underwriters Laboratories, a company nationally recognized for
product safety testing.
Voltage: The electrical power, in volts, of pressure supplied by an electrical circuit to a lighting source. Standard US
power supply is 120 V 60 cycle (277 V 60 cycles in commercial spaces). Standard international power supply is 220
to 240 V 50 cycles. It is the pressure of the power supply similar to the psi pressure in a pipe.
Watt: The unit of power consumed by any electrical device or lamp (bulb).
