Delta-88 Main AC Connections
The Delta System has specific AC connection requirements and these will depend on the
components included in your particular installation. Because the Delta System is an ADA
Bus™ system, it will automatically re-boot every time the system is provided with AC. While
throwing a single AC circuit breaker could re-boot the system, in many cases several AC
circuits are used, especially for larger systems. Furthermore, it may be impractical to use a
circuit breaker switch to re-boot the system. To this end, several options exist regarding AC
wiring which will permit the Delta System to re-boot from a single power switch on one of your
system's ADA components. Most frequently, this single power switch will be found on one of
two ADA Bus™ components, the Delta-88 or the ACC-3000. In a system using several Delta-
88s, only one Delta-88 (the main unit, not a slave unit) will have a power switch designed to
re-boot the system. Follow the guidelines at the top of the pages in this section to determine
which Main AC wiring diagram best suits your application.
Option 1 - One Delta-88, No PCT-8, & No ACC-3000
This is one of the more basic scenarios where the Delta-88's power switch will re-boot the
system when it is turned on and off. No additional devices are required. Plug the Delta-88 into
a wall outlet.
Warning! While one of the first sections discusses plugging in the Delta-88, this step should
be done just prior to system testing. When testing the source or external amplification AC
wiring, plug the Delta-88 into an AC outlet, do the required testing to verify the AC
switching operations, shut down the Delta System, and then turn off the Delta-88's Main
Power Switch. Once the Delta-88 is off, unplug the unit and continue with the installation
of the ADA Bus™. Once the ADA Bus™ is connected you can then plug in the Delta-88.
