Overview
The OMX-WCI is for use
with
GRAFIK 5000/6000/
7000
series systems. The
OMX-WCI mounts
behind the user-supplied
switch to select or adjust
scenes in up to eight
control units. The
interface provides from
two to seven contact
closure inputs.
Description
• The OMX-WCI provides 7 control inputs to the Lutron
lighting control system.
• The control inputs can be set up to simulate existing
Lutron keypad functionality or custom-configured to
project-specific requirements. Please contact Lutron for
details.
• Provides 1-way interface between Lutron lighting
system and an input switch.
• Mounts behind the user-supplied switch to control the
Lutron lighting control system.
• Works with a PELV (Class 2: USA) low-voltage dry
contact switch that meets the power requirements
found in the Specifications section of this document.
• The power LED provides feedback:
- Flashing indicates a miswire on the communication
link or that the system processor is off-line.
- When the nightlight option is set, the LED will be
steadily lit when polled.
- When the nightlight option bit is cleared, the LED will
not be lit when polled.
• The recommended wallbox depth is 61 mm (2.5 in.).
The wallbox depth requirements vary with the depth of
the switch being used.
• The OMX-WCI uses one address on the communication
link.
• Can be custom-configured for other functions.
Caution:
The OMX-WCI is
not
designed to work
with the line/mains voltage switches. Use with
line/mains voltage switches could result in
premature failure of the switch being used.
Caution:
Install in accordance with all local and
national electric codes.
Specifications
Power
• Operating voltage: low-voltage PELV (Class 2: USA),
24 V
.
• Input switch or dry contact switch closure must have
solid-state outputs with an on-state saturation voltage
less than 1 V
at 1 mA and an off-state leakage
current of less than 1 mA. Outputs must be capable of
switching operating voltage for desired life of system.
• If there is any question as to whether a switch is
compatible with these specifications, contact the
manufacturer of the switch.
Key Design Features
• Meets IEC 801-2. Tested to withstand 15 kV
electrostatic discharge without damage or memory
loss.
System Communications and Capacity
• PELV (Class 2: USA) low-voltage wiring connects
wallstations to control units and other components.
• Link up to 32 wallstations, control units, and/or control
interfaces per wiring link.
Terminals
• Capacity: Accept up to two 1.0 mm
2
(#18 AWG) wires
typical.
Environment
• Ambient operating temperature 0-40 °C (32-104 °F),
0-90% humidity, non-condensing.
Indoor use only.
