INSTALLATION: MULTI-CONTROLLER SYSTEMS
Notes on multi-controller set-up
Power Toggle Set-up
We recommend in systems with multiple RMZ-955 controllers (with full AC control from any Zone) that you select source com- ponents that do not require a “power toggle” command, i.e. com- ponents that fully power up when AC power is applied, instead of going into a standby mode.
If sources requiring a “power toggle” command are used, only one RMZ-955 controller should have the “power toggle” feature activated (i.e. set to “y” during setup). Make sure that the
“Power Toggle” command is DEACTIVATED for all other RMZ-955(s).
Even though the default “Power Toggle” setting is OFF, verify that this has not changed by temporarily connecting an RSM-901 to the Zone A data terminal of each remaining RMZ-955, entering Set-up Mode as outlined and pressing the RLC-900 “n” (for No) key. Continue to hold the “n” key and press the other set-up key “y” to exit setup.
This is a critical step in a system using multiple RMZ-955s. If the “Power Toggle” is not deactivated for the additional RMZ-955(s), source components will not turn on and off properly
—in fact, source components may actually turn off when RMZ-955s turn on.
Source Component Set-up
Programming of command code sets for source components is covered in the following section of the manual. However, keep in mind that in systems with multiple RMZ-955 controllers, it will be necessary to reprogram these codes for each RMZ-955 in the system. This must be done from an RSM-901 sensor display con- nected to Zone A on each controller.
“Engaged” Indicator
The “Engaged” indicator on a remote zone’s RSM-901 sensor/ display(s) will indicate other same-source users only in zones connected to that particular RMZ-955 controller/amplifier.
For example, in an 8-zone system using two RMZ-955s, a CD lis- tener in Zone 7 (connected to the second RMZ-955) would have no indication that another user in Zone 2 (connected to the first RMZ-955) was listening to the same source. If a third listener in Zone 4 then selected CD, only the listeners in Zones 2 and 4 (both connected to the same RMZ-955) would know that someone else was sharing the same source.
