DESCRIPTION OF UNIT
The AC1109 is a wall mounted, eight scene, remote
station for use with the Lightronics LitNet
architectural control system. The LitNet host units
consist of the AR and AB series of architectural
dimmers, the RA rack mount dimmers and the SR &
SC architectural controllers. User operation is as
simple as it can get (eight numbered scene buttons
and an "OFF" control). LED scene indicators
always display the active scene number.
The unit fits into a standard single gang wall switch
box. The unit communicates on LitNet via a four
wire bus which will accommodate several remotes
and other controls. All LitNet wiring is low voltage.
The unit basically operates in an exclusive mode
where one scene may be activated at a time. When a
scene is selected, the lighting circuits fade at a user
controlled rate to that scene. A blackout button is
also provided to shut all scenes.
Scenes activated by the AC1109 are actually set up
and stored in the LitNet host. The AC1109 only
tells the host which scene to activate. The host can
be programmed to respond to the AC1109 in various
ways to create zone controls.
The AC1109 is normally factory set to operate with
scenes 1 - 8 (block 1) of the dimmer. It can be
factory set to operate with other blocks of 8 scenes
as follows.
Multiple AC1109 units using different scene blocks
can be used together to create zone control.
INSTALLATION
The AC1109 connects to the LitNet system via a
shielded 4 conductor cable arranged as 2 twisted
pairs. One pair connects to the DATA - and DATA
+ signals. The other pair carries the common and
power. Refer to the diagram AC1109
CONNECTIONS in this manual for additional
wiring information.
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 connects
to the host by different methods. Refer to the host
product Owners Manual for additional wiring
details.
MULTIPLE UNITS: Follow the instructions for a
single unit for the first AC1109. Connect pin 1 of
the second unit to pin 1 of the first unit. Continue for
the remaining wires and shield. Repeat the
procedure for additional AC1109 units.
OPERATION
No setup or turn on procedure is needed. When the
LitNet host is powered on, the AC1109(s) will also
be powered. If communication with the LitNet host
cannot be established, an AC1109 will appear to be
repeatedly scanning through all scenes.
Scenes to be activated by an AC1109 must have
already been created and stored in the LitNet host.
See the host product Owners Manual for instruction
on programming scenes.
If a scene is activated from an "OFF" condition but
has no channels assigned to it which are on or
partially on then the scene LED indicator will light
and the "OFF" indicator will remain lighted.
If a scene with no channels on or partially on is
activated while another scene which does have on or
partially on channels is active then the LED
indicator for the scene will light and the previous
scene indicator will remain lighted
