In a very large room, you may want to provide a separate IR sensor across the room from a Select
™
IR or Solo
™
IR Master Keypad Module.
With a separate IR sensor, a source component's actual IR commands (i.e., provided by the component's
original remote control or a learning remote control programmed with these IR commands) will control the
source components.
Important Note: The ZR-8630AV does not provide individual operation of identical source components when
using a source component's factory remote through an IR sensor. (See Identical Source Components on page
43 for more details.)
Source-Component Automation
There are two methods of managing the power ON/OFF of the source components.
1.
Synchronized IR - In Figure 4, a video signal connected to the ZR-8630AV synchronizes the DSS receiver’s
power ON/OFF. When the Master Key/Source Button for the DSS is pressed, the ZR-8630AV checks for a
video signal at the Sync Input corresponding to the DSS.
The ZR-8630AV issues the power command to turn
the DSS ON only when no video signal is present and the DSS is OFF.
When the Off Key/Button is pressed in a zone, the ZR-8630AV checks to see if any other zones are ON
(including the Home Theater Zone sharing sources). The power command for turning the DSS OFF is issued
only if that zone is the last zone turning OFF in entire system and a video signal is present at the Sync Input
corresponding to the DSS.
Important Note: 12V Sync Inputs can detect 12V for use with Niles external sensing devices, (i.e. the LS-1 Light
Sensor and the APC-2 Current Sensing Device). See Connections on page 46 for more information.
2.
Latching Power - In Figure 4, the switched AC outlets of a Niles AC-3 AC turn power to the DVD and CD
changer on and off. The 12V Control Output from the ZR-8630AV activates the AC-3 when any of the six
zones is ON (including the Home Theater Zone sharing sources). The built-in AM/FM tuners also turn ON
when any of the six zones is ON.
Each Master Key on the Master Keypad Module and its respective source component are programmable with a
sequence of IR commands. Commands included in the sequence typically are the Play or Channel commands to
start a source playing or to select a particular music or radio station after the source has been selected.
Flasher Outputs
Niles IRC-2P MicroFlashers
™
connect to the numbered flasher outputs on the rear panel of the Niles ZR-8630AV.
Flashers send IR commands to the individual source components for control. To control more than one source
component, connect an IRC-1P Flooding Flasher to the Flasher output labeled ALL .
Video Outputs
Each zone has “home run” RG-6 coaxial cable with 100-percent quad-shielding from the video output to a TV
set or other video-display device located in the zone. To avoid video-signal degradation, such runs should not
exceed 500 feet (152 meters).
Speakers
“Home run” speaker cables from the speakers in each zone connect to the built-in zone amplifier. Connections to the ZR-
8630AV unit’s speaker output terminals employ Niles’ patented no-strip speaker connectors.
