Description of the DELTA System (cont.)
WH-3000 ADA Bus™ Wire Harness • an ADA Bus™ Component • All ADA
Bus™ Components connect to this harness. The WH-3000 provides fuse
protection for short circuits which incorporate automatic reset. One WH-
3000 is required for every eight ADA Bus™ Components. If you are using
more than eight ADA Bus™ components, add one WH-3000 for every eight
additional devices.

LVI-3800 Low Voltage Relay • an ADA Bus™ Component • This device can be used in a
variety of applications.
Option 1 - Zone Source Tracking - The LVI-3800 can be set to track
a specific zones source selection such that an AC controller
for a projector and screen (ACC-3) receives a control signal
to turn on only when a video source is selected. When an
audio source is selected or the zone is turned off, the
projector will turn off. If a projector, screen, or even a TV can
be controlled via a switched AC outlet, the addition of an
ACC-3 permits automatic AC control of the video hardware
when only a video source is selected.
Option 2 - MC-3800 Softkey Contact Closure & Voltage - The LVI-3800 can be set so that the
extra six buttons on the MC-3800 Series controls trigger momentary switches for control
of lighting, curtains, etc. No other wire will need to be run to the keypad and the LVI-
3800 can be located anywhere in the house providing that an ADA Bus™ is run to its
location.
Option 3 - Source Transport Controller - The LVI-3800 can be set to control sources which do
not operate via IR or Serial Data. This application can only be done for one of the eight
sources and would permit as many as seven different functions for that source from the
keypads. These functions are translated to momentary low voltage relay closures
making this package ideal for control of a slide projector or other low voltage controlled
source.
Assorted Support Hardware
as MT-3000s and SSD-66s from picking up control data
noise. One unit is required for each MT-3000, SSD-66, and
SSD-66THX used in a Delta System. BI-3000s are also used
to isolate different ADA Networks which come into play
with larger more elaborate systems.
