3. If longer wires are required for the IR350, solid or stranded,
shielded or unshielded with a minimum of 28-gauge for runs
under 200’, 22-gauge for runs under 500’ and 20-gauge for
runs up to 1000’. Wires can be looped from IR350 to IR350 or
home run. Home wire runs normally offer more reliability and
future flexibility.
4. IR350s can be mixed and matched in larger systems with up
to 10 Knoll infrared receivers.
5. When connecting multiple Knoll infrared receivers to the
IR155 detachable connector, make sure the infrared receivers
are wired in parallel only. For a single IR350 connected to the
IR155 infrared hub the red plug can be connected to the IR155
red jack. If the wire length needed is longer or multiple infrared
receivers are to be connected use the following procedure:
Connect the infrared receiver(s)
12V
,
GND
and
SIG
terminals
to the corresponding IR155 screw terminals. Prepare the wire
leads to and from the IR receivers by stripping about ¼” of the
insulation from each of the three leads. Twist the strands tightly
together so that they do not stick out of the connector and
cause a short circuit. Strictly observe polarity.

6. Next, plug the single or dual emitter(s) into the Knoll
connection block and position and attach the emitter output to
the source components infrared receiver window.

7. Plug in the power supply. The Knoll PS1205 can power one to
ten infrared receivers, one connection block and one to four
single or dual emitters.
8. The infrared system is usually left plugged in all the time (to
an unswitched outlet) as it uses very little power.
9. Test the infrared system to see if it is working properly.
Bright sunlight and passive infrared security systems can lower
the distance that remote controls can work with an IR350
receiver.
