Chaining Multiple CT-1’s
Multiple CT-1 IR Integrators can be combined for very large systems. A total of 11 CT-1’s can be chained
together to form 126 independent stereo zones. This allows IR control of the entire CT system and each of
the nine shared source devices. Each additional CT-1 uses one of the three CT FLASHER IN sections on the
CT-1. Each multi-linked CT-1 will accommodate a maximum of two CT receivers (See diagram below). Using
this method will allow IR routing from any of
the 126 potential independent zones to any
of the nine shared sources. The diagram
shown to the right illustrates six CT
receivers linked together (36 stereo zones).
Always connect all 9 IR flashers from the
CT receiver(s) to the CT-1
. This is needed
for proper IR routing when the dedicated
inputs or the tuner is selected.
Notice that IR is passed between CT-1s
using the CHAIN OUT to CHAIN IN 1/8” mini
jacks. Therefore, IR data passes from CT-1
#1 to CT-1 #2 to CT-1 #3. Additional CT-1s
can be added at the bottom of this chain by
continuing the method shown. Source
devices are always connected to the last
CT-1 in the chain. A maximum of 11 CT-1s
can be chained together.
IR data cannot be passed “up” the chain of CT-1s (from #3 to #1). Keypads that are programmed with whole
house control (code 000), need to be connected to CT Receiver #1 or #2 in this example. Keypads that
intended to control other zones in the house will only have the ability to control zones located
downstream
of
where that keypad’s IR signal is entering the chain.
Please refer to our website for additional information pertaining to specific installation scenarios and
programming the system keypads.
