Sivoia QEDTM Quiet Electronic Drive Window System 1.2
EDU wiring
Wiring
FUNCTION:
Sivoia QED Electronic Drive Units (EDUs) are designed to
function in four ways:
• A single EDU can be controlled individually by a keypad,
IR transmitter, or contact closure interface (CCI).
• Multiple EDUs can be linked through programming to
operate in groups and subgroups, regardless of location
on the link. EDU groupings can be changed at any time
simply by reprogramming the system.
• EDUs can be operated by larger entire-room or whole-
house lighting control systems such as Lutron’s
GRAFIK
Eye
®
, or
HomeWorks
®
systems.
• EDUs can also be operated by control systems made by
other manufacturers.
GENERAL FACTS:
• Microprocessors are contained in the EDU, keypad, CCI
and IR transmitter, allowing high-level programming
from any source.
• The keypads are low-voltage and receive their power
from the EDUs. EDUs receive their power via a 24 V~
power supply. One power supply is required per EDU.
• Keypads are wired directly to a communication link,
which connects to one or more EDUs, CCIs and keypads.
See Programming Section for more information on EDU
grouping by function.
• A contact closure input is available, when required, to
connect with an outside system. The contact closure
input wires to the EDU communication link.
PLANNING YOUR INSTALLATION:
Taking time to plan out the wiring on paper will help
enormously, especially in multiple EDU installations.
Some common questions to answer up front include:
• What are the power requirements?
Sivoia QED
system operates on 24 V~ and requires
the use of a low-voltage power supply.
The specification of the power supply is provided on
page 1.4.
Each EDU must be powered from its own power
supply.
A certified electrician should install all of the line
voltage power.
The keypads are all low-voltage and can be installed
by a low-voltage system installer.
• What size of cable is needed?
Please refer to the charts on page 1.4.
• Can I expand the system later on?
A communication link can connect up to 96 total
devices (EDUs, keypads or CCIs).
An external keypad power supply is required when
the total number of keypads and CCIs in an
installation exceeds the number of
Sivoia QED
EDUs.
