VIS
Infrared Receiver on Knoll Stereo
Volume Controls
Installation Instructions v1.0
Warning: To be installed and/or used in accordance with
appropriate electrical codes and regulations.
Introduction: Thank you for your purchasing another Knoll
product! The VIS module is an infrared receiver that is mounted
on one of our volume controls. It does not directly control the
volume control. Follow the volume control installation directions
shipped with this product. This receiver features the ability to
pick up a remote control infrared signal from up to 25 feet away
and relay it on wires to another location up to 1000’ (or more).
Features:
• Inwall junction box
design available in
ivory, almond and black
colors.
• Will relay almost all
remote control types
(except some B & O
models).
• Can be connected with
almost any 3-conductor
wire including cat 5.
• Requires very little
power. Suggest using
PS1202 12 VDC (200
mA) for up to 5 IR21s.
• Up to 10 IR10’s, IR21’s
IR25’s and other compatible models can be connected
in a single system.
• Connects with a three wire connector or RJ45 via cat 5
wire.

Installation Tips
1. Follow all local electrical & building code requirements.
2. The VIS is usually wall mounted. It does not normally require
a junction box. For easy installation and to ensure reliability, it
is suggested that a PS1202 (200 mA) or PS1205 (500 mA) 12
VDC unregulated power supply, IR31a (single) or IR34a (dual)
emitters and one of the following: IR54 (decora inwall style, 4
output) or IR55 (tabletop style, 4 output) connection block, be
used.
3. Wires can be 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 VIS to VIS or home run. Home runs generally offer
more reliability and future flexibility.
4. VIS’s can be mixed and matched in larger systems with up to
10 infrared receivers, such as the Knoll IR10 or IR22.
5. To wire the system together, connect the VIS 12V, GND and
SIG terminals to the corresponding IR54 or IR55 terminal.

Connection
Block
Prepare the wire leads to and from the VIS 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.
Try to make sure the wires do not touch any of the white cermet
tile resistors.
6. Next, plug the single or dual emitters into the IR54 or IR55
connection block.
7. Now, plug in the PS1202 (for up to five receivers) or PS1205
for five to ten receivers.
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 IR21
receiver. If you have any questions or concerns, please call and
ask for infrared technical support at 1 800 566 5579. The Help
Line is open from 7:30 a.m. to 5:00 p.m., Monday to Friday,
Pacific time.
