INTRODUCTION
The AF-2104 is a 4 scene, wall mount remote control
unit intended for use with the Lightronics AR-1202
Architectural dimmer. The unit fits in a standard
double gang wall switch box.
All power and data connections are via a 4 wire
communication bus between itself and the AR-1202
dimmer.
In addition to manual fader control of 4 scenes,
pushbutton switches are provided to activate a blackout
and full on selection. LED indicators provide status
feedback.
Multiple units may be chained together to provide
dimmer control from various locations. The AF-2104
may also be used with other Lightronics architectural
remote stations.
INSTALLATION
CONNECTIONS
The AF-2104 connects to the AR-1202 dimmer via a
shielded 4 conductor cable arranged as 2 twisted pairs.
A data grade, low capacitance cable (less than 25 pf
per foot) is required to assure trouble free data
transmission to and from the AF-2104. One pair
connects to the
DATA –
and
DATA +
signals. The
other pair carries the power
(REMOTE V+)
and
COMMON
. The cable shield should be connected to
the
COMMON
.
A connection diagram is provided at the end of this
manual.
CONNECTING A SINGLE UNIT: Connect the 4
cable wires to the screw down terminals on the back of
the unit. Connect the cable shield to the
REMOTE
COMMON
pin. The other end of the cable will
connect to a terminal strip provided in the AR-1202
dimmer unit. See the AR-1202 owners manual for
exact connection details.
CONNECTING MULTIPLE UNITS: Follow the
instructions above for a single unit for the first AF-
2104. Connect the corresponding connector pins of the
second unit to those of the first unit.
MULTIPLE UNITS OF DIFERENT TYPES: The AF-
2104 may be connected together with other Lightronics
smart remotes. These remotes all have the same
connection scheme. Connect the AF-2104 to the other
remotes by connecting like signal names together
(REMOTE COMMON to REMOTE COMMON etc.).
SCENE ASSIGNMENTS
AF-2104s operate by fading scenes 51 thru 54 in the
AR-1202. The left hand end fader (#1) corresponds to
scene 51. If multiple AF-2104 units are used together
then they will all operate scenes 51 - 54.
It is possible to have an AF-2104 operate other scenes
but the unit must be ordered with special programming.
OPERATION
No setup or turn on procedure is needed. When the
AR-1202 unit is powered on, the AF-2104 will also be
activated. It will activate in the "All Scenes OFF"
condition.
The scenes activated by the AF-2104 must be created
and stored in the AR-1202 prior to activation. See the
AR-1202 owners manual for detailed instructions for
creating and storing scenes. Scene numbers proceed
from left to right at the AF-2104.
The AF-2104 faders operate in a pile-on mode on a
"greatest of" basis. This means that the intensity of a
dimmer channel will be at the intensity of the scene
calling for the highest intensity level.
The OFF button causes all four scenes to be blacked
out (turned off).
MAINTENANCE AND REPAIR
TROUBLESHOOTING
Check the cable and its connections.
If the unit is being used with an AR-1202 system -
ensure that one (and only one) of the AR-1202
dimmer(s) in the system is set to UNIT ADDRESS 00.
