READ FIRST

Setup Guide for the RadioRA Chronos System Bridge2
1. It is recommended that only one GRAFIK Eye®Control Unit be wired to each GRAFIK Eye Interface. Multiple GRAFIK Eye
Control Units may be wired (linked) to the same GRAFIK Eye Interface, however, all GRAFIK Eye Control Units on that
link will respond in unison to the commands from the GRAFIK Eye Interface. ALL GRAFIK Eye Control Units wired to the
same Interface will carry out ALL commands from the GRAFIK Eye Interface (i.e. go to GRAFIK Eye scene 3, Turn OFF,
etc...). Interface commands cannot be sent to one individual GRAFIK Eye Control Unit on a link of multiple GRAFIK Eye
Control Units.
• This application may be desired if multiple GRAFIK Eye Control Units are in the same room and it is intended that
the same scene be selected on each GRAFIK Eye Control Unit simultaneously.
• Lutron does not recommend using one GRAFIK Eye Interface to linked GRAFIK Eye Control Units located in more
than one room.
2. Scene 1 on a GRAFIK Eye Control Unit is the default scene for ALL ON, SECURITY, and FLASH MODES. It is recom-
mended that Scene 1 on GRAFIK Eye Control Units be set to full intensity with a fade time of zero seconds.
3. Setting the light levels for GRAFIK Eye scenes should be done prior to any operations in this Setup Guide.
4. A GRAFIK Eye scene may be added to any RadioRA®Master Control button which has been previously programmed
without altering that buttons existing programming.
5. See RadioRA Application Note No.48 (P/N 366-730) for steps to activate GRAFIK Eye scenes 5-16 from a RadioRA
Master Control.
6. For information on integrating your RadioRA system with a photocell, telephone interface, shade motor control, etc... see
the RadioRA Application Notes on our web page at www.lutron.com/applicationnotes/index.html.
7. RadioRA lighting control systems use radio frequency technology for communication. Currently, RadioRA lighting control
systems are available in two frequencies. To determine the frequency of a RadioRA product, examine the model number
on the product’s unit label. The labels are located on the side of all “wallbox” products, and on the bottom of all “tabletop”
products.
The second letter in all RadioRA model numbers indicates the product’s frequency. For example: RA-6D is an “A” fre-
quency product, whereas RB-6D is a “B” frequency product.
Note: Do not mix RadioRA “A” and “B” frequency products within the same system. Products with different frequencies
are not compatible.
If you have any questions concerning the installation or operation of this product, please call the Lutron Technical
Support Center at 1-800-523-9466.
Important Application Notes
System Operation Notes
This guide replaces the Setup Guide (P/N 044-001) included with a system Repeater.
The installer should be aware of the following:
1. In order to install the ChronosTM System Bridge as the Main Repeater in an existing system, all devices in the system must
be returned to their factory defaults prior to installation of the Chronos System Bridge.
2. When using a Whole-home Button on a Master Control, there will be a delay between when the Whole-home Button is
pressed and when the scene activates. The delay will typically be approximately 2 seconds. This applies for scenes that
contain zones of lighting in one system or in both systems. The delay does not apply when the button is activated via
RS-232.
3. For Whole-home Buttons that contain lighting in both System 1 and System 2, the scene will activate one system at a
time, with a delay in between. The delay is typically 3 seconds. The system that the Master Control is in determines which
half of the scene activates first.
4. Only unprogrammed Master Control buttons can be used as Whole-home Buttons. All local programming must be erased
from a Master Control button before it can be assigned as a Whole-home Button.
5. When using Cordless Tabletop Master Controls, the Master Control LEDs will not update when the Master Control is first
awakened from a “sleep” state.
6. When using Master Controls with Raise/Lower buttons with the Chronos System Bridge, the Raise/Lower buttons will not
work on Whole-home scenes.

Consumer Information
Danger
This RadioRA®system must not be used to control equipment, other than lighting, which is not visible from every mas-
ter or local control location. It also must not be used to control equipment which could create hazardous situations
such as entrapment if operated accidentally. Examples of equipment which must not be controlled by this RadioRA
system include (but are not limited to) motorized gates, garage doors, industrial doors, and microwave ovens, heating
pads, etc. It is the installer's responsibility to ensure that the equipment, other than lighting, being controlled is visible
from every master or local control location and that only suitable equipment is connected to this RadioRA system.
Using the ChronosTM System Bridge with Older RadioRA®Lighting Zone Controls
On RadioRA Dimmers, Switches, and GRAFIK Eye®Interfaces shipped prior to January 1, 2001, the Legacy setting for fade
times must be used. Raise/Lower functions from Master Controls and the Level Capture feature are also not supported by
these devices shipped prior to January 1, 2001.
Using the Chronos System Bridge with Older RadioRA Master Controls and Interfaces
The Chronos System Bridge Whole-home scenes will not work with Master Controls shipped prior to January 1, 2001. The
buttons on these Master Controls do not send programming necessary to activate the Chronos System Bridge scenes. Also,
this feature was not supported in RA-RS232 and RA-IR Interfaces shipped prior to September 1, 2001. For this reason,
these older devices cannot be used to activate Whole-home scenes.
Using the RA-SCI Switch Closure Interface
The Switch Closure Interface cannot be used to activate Whole-home scenes. The security mode inputs on the Switch
Closure Interface will not work across systems. If a security system is connected to the RA-SCI security inputs, it should be
moved to the security input on the Chronos System Bridge. Refer to Section 6 for instructions on setting up the Chronos
System Bridge contact closure inputs.
Using the RAMC-MFE-WH Security Mode Inputs
The security mode input on the RAMC-MFE-WH will not work across systems. If a security system is connected to the
RAMC-MFE-WH security input, it should be moved to the security input on the Chronos System Bridge. Refer to Section 6
for instructions on setting up the Chronos System Bridge contact closure inputs.
Using Security mode from a RA-RS232 Interface
Security mode activated from an RA-RS232 Interface will not work across systems. If a third-party system is connected to an
existing RA-RS232 Interface, it should be moved to the RS-232 port on the Chronos System Bridge. Refer to Section 5 for
instructions on setting up the Chronos System Bridge RS-232 port.

• Input devices can be driveway sensors,
photocells, security systems, etc.
Contact Closure Compatibility: The input closures
are intended for use with devices that provide main-
tained or momentary outputs in the form of dry con-
tact closure or open collector outputs meeting the fol-
lowing criteria:
• On saturation voltage: < 1.0 V at 2 mA
• Off leakage current: < 10.0 µA at 12 V
• Outputs must stay in the closed or open state for
at least 40 msec in order to be recognized by the
Chronos System Bridge
If there is any question as to whether the contact clo-
sure device is compatible with these specifications,
contact the manufacturer of that device.
Contact Closure Wiring:
Caution - DO NOT apply voltage between any two
terminals on the Chronos System Bridge contact clo-
sure input terminal block. This will cause improper
operation and could damage the Chronos System
Bridge and the connected equipment.

Activate Auxiliary Repeaters
This procedure needs to be performed only if the ChronosTM System Bridge is configured as a Main Repeater. If
the Chronos System Bridge is not configured as a Main Repeater, skip this procedure. Repeaters must be in
their permanent location in order to be activated. Note: Additional Auxiliary Repeaters (up to 3 Repeaters total
per system) can be added to a system to increase range and improve reliability.
Ensure all system devices are powered up and operating prior to adding any Auxiliary Repeaters.
