Installation Tips
1
. Follow all local elect
rical & building code requirements.
2
. The DIR21 is usually wall mounted at light switch heigh
does not normally require a junction box. In order to work it
requires a PS1202 (200 mA) or PS1205 (500 mA) 12 VDC
unregulated power supply, IR31 (single) or IR34 (dual) emitt
A connection block is not needed.

1000'. Wires can be solid or stranded, shielded or unshield
with a minimum of 28 gauge for runs under 200', 22 gauge fo
runs under 500' and 20 gauge for runs up to 1000'.
4
. Cut off the plugs of both the PS1202 power suppl
emitter to be used. Strip back and connect the two – or groun
wires of the power supply and emitters (non white stripe on
wire) together with the wire conductor going to the "GND"
terminal of the DIR21P. Next connect the emitter + wire (the
one with the white stripe) to the wire going to the DIR21P "SI
terminal. Then connect the PS1202 power supply + wire (the
one with the white stripe) to the wire going to the "12V"
terminal on the DIR21P. Polarity must be strictly observed.

5. Position the emitters over the IR receivers on the
component(s) to be controlled, plug in the PS1202 power supply
and the system should be ready to go.
6. The infrared system is usually left plugged in all the time (to
an unswitched outlet) as it uses very little power.

7. Test the digital infrared system to see if it is working
properly. If it works only from a very close range or it does not
work at all, first mark where the pot adjustment is on the
DIR21P blue color pot on the rear of the DIR21P. This is so you
can reset it to that starting point again. Try adjusting the pot on
r
the connection block very slightly left and right as you are
testing the receiver with the remote control. This may require
two people. This should correct for the problem. If it still does
not work properly, please call Knoll Systems and ask for infrared
