Niles Audio MRZ-6 - Manual (Page 14)

IR Connections for a System with a Dedicated Preamp/Receiver and up to six MRZ-6’s
As explained on page 7, a single zone system can be expanded to distribute a single source to up to 36 rooms using
six MRZ-6 units. See Figure 17
• A 12VDC wall adapter is connected to the switched outlet of the Preamp/Receiver to provide sync (or sta-
tus) to the first (or Master) MRZ-6. This switched outlet may also be used to power up source components
which have latching power.
• The UART connection enables the Slave MRZ-6’s to power on the Preamp/Receiver using the automation
codes taught to the Master MRZ-6. The UART connection also enables All On and All Off control of all the
rooms in the system. See page 20 of the MRZ-6 manual.
• DATA OUT of the Slave MRZ-6’s is connected to the DATA IN of the Master via the DATA IN and DATA
OUT jacks. See Figure 15.
• Only the Master MRZ-6’s Dedicated flasher output is connected to the Preamp/Receiver’s front panel IR
sensor.
• When using RP-9 keypads, all automation codes are taught to the Master MRZ-6 only.
For more information concerning IntelliPad®/MRZ-6 programming, see page 26 of the MRZ-6 manual.
• Both ZONE DIP switches should be set to the UP (or single zone) position. IR codes received at any of the
MRZ-6’s sensor inputs are passed through DATA IN and DATA OUT terminals and output via the Master
MRZ-6’s Dedicated and Common flasher outputs.
