IR350
Postage Stamp Infrared Receiver
Installation Instructions v1.0
Warning: To be installed and/or used in accordance with
appropriate electrical codes and regulations.
Introduction: Thank you for your purchase of a Knoll IR350
infrared receiver. This receiver features the ability to pick up a
remote control infrared signal and relay it on wires to the inside
of a cupboard or to another location up to 1000’ (or more).
Actual size
Features:
Very small design.
More forgiving than previous
designs and can work short
distances in direct sunlight.
Will relay almost all remote
control types.
Requires very little power.
Suggest using Knoll PS1205
for up to ten IR350’s.
Up to ten Knoll infrared receivers can be connected in a
single system.
Connects with a three wire connector or 3.5mm plug.
Installation Tips
1. Follow all local electrical & building code requirements.
2. The IR350 is usually mounted to the wall or cabinet using the
included double sided tape. For easy installation and to ensure
reliability, it is suggested to use a Knoll PS1205 power supply,
Knoll single or dual emitters and a Knoll connection block or
hub.

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.
