When the Home Theater turns ON, it provides a 12V status signal that is connected to the Home Theater
sync input on the rear panel of the A4.6Ci. This 12V status signal provides the ON/OFF status of the
Home Theater to the A4.6Ci.
The moment a valid Home Theater sync signal is present at the A4.6Ci, the A4.6Ci’s 12V control out-
put sends a turn-on trigger for a voltage-triggered AC power strip (i.e., Niles AC-3), activating latching
source components.
When the Home Theater is turned OFF, the A4.6Ci checks itself and any other A4.6Ci’s in the system to
see if any zones are still ON. If all zones are OFF, the 12V control output shuts OFF, turning OFF the
latching source components. Power OFF IR commands for turning OFF the IR-controlled shared source
components also are issued.
Method 3. Integrated Home Theater without 12V Home Theater Sync and Using Niles R-4 Commands
The Home Theater IR remote (programmed with the Niles R-4 IR commands) sends IR commands to the
A4.6Ci via the IR input located on the rear panel. This enables control of the shared source components
for users in the Home Theater.
All the actual IR commands for shared source components are programmed into the A4.6Ci. When a
Niles IR command is received, the corresponding programmed source IR commands are sent to the
flasher output dedicated to the shared source component that is selected (i.e., Source 1 = Flasher 1,
Source 2 = Flasher 2, Source 3 = Flasher 3, Source 4 = Flasher 4). Identical source components can be
individually operated with this method.
Important Note: Shared source components that are unique in the system may have their actual IR com-
mands programmed into the Home Theater remote and issued for simple IR repeating using this method.
When the Home Theater is turned OFF, the Home Theater remote sends a Niles OFF command to the
A4.6Ci. The A4.6Ci then checks all zones, for all A4.6Ci’s in the system. If all zones are OFF, the 12V
control output shuts OFF, turning OFF the latching source components. Power OFF IR commands for
the IR-controlled shared source components programmed into the A4.6Ci also are issued, conditional-
ly, based on the source-sync status of the shared source components.
SYSTEM-BUSY INDICATION
The A4.6Ci has a built-in system-busy indication mode that is displayed on the Master Key LEDs of the Solo
™
Master Keypad Module. If the A4.6Ci receives simultaneous commands from two different users and each user
is located in a separate zone, the user who does not get the expected response will be alerted by the Master
Key. That Master Key LED will quickly blink RED three times. The user who received the RED flashing Master
Key simply issues his or her command again.
Important Note: IR commands and delays included in the sequence for Master Keys also cause the system to indi-
cate busy while they are being executed.
PAGING INDICATION
The A4.6Ci has a built-in paging-indication mode that is displayed on a Master Key LED of the Solo
™
or Select
™
Master
Keypad Module. If the A4.6Ci sends a page to a zone, the user is alerted by the Master Key. That Master Key LED will
blink slowly GREEN. The Master Key LED resumes its last state (ON or OFF) when the page is completed.
Important Note: Paging takes priority over all system functions until the page has ended.
