Crestron 24 Volt DC Design Guide
2
Introduction
This design guide is intended to explain how to design a Crestron
system using EMerge Alliance
®
standards. Before understanding how a
Crestron system integrates with EMerge, it is important to know how
the EMerge Alliance infrastructure differs from today’s traditional infra-
structure. This guide will touch on the features and benefits that applications of the EMerge
Alliance 24 Volt DC standard bring to the table, as well as go into detail on specific
Crestron products designed specifically for use with the new EMerge standard.
What is the EMerge Alliance?
The EMerge Alliance is a not-for-profit open industry association leading the rapid adoption
of safe DC power distribution in commercial buildings through the development of EMerge
Alliance standards. The Alliance was established in 2008 by industry leading corpora-
tions including Armstrong World Industries, Johnson Controls, Nextek Power Systems,
OSRAM SYLVANIA, and Worthington Armstrong Venture (WAVE). The goals of the Alliance
are to create more energy efficient and flexible building spaces while improving overall
sustainability.

EMerge Technology
The Alliance developed an open standard that integrates interior infrastructures, power,
controls and a wide variety of peripheral devices, such as lighting, in a common platform to
reduce energy loss associated with powering the many digital DC powered devices found
in today’s workplaces.

Currently, the most common application is a low-voltage ceiling
grid, capable of powering lighting fixtures. The benefit is an extremely safe and flexible
power distribution system for lighting and other potential future uses. In open-plan office
space, rearranging desks doesn’t require high costs of rearranging lighting fixtures. Simply
relocate an EMerge Alliance Registered fixture to another spot on the grid.
Crestron and the Alliance
Crestron is currently a participating member of the EMerge Alliance. Participating members
are key suppliers of products and technology that comply with EMerge standards. As a
member, Crestron participates in committee proceedings and plays a role in the develop-
ment of specifications. Members have total access to all EMerge specifications, which are
critical in development of products.
Crestron has already developed a lighting control system for use with the 24 Volt DC
EMerge standard, and plans on continued development of sustainable products which will
help grow the standard platform.
