Definitions of Common Terms
Glossary
Master Control -
A RadioRA
®
Master Control is a system control point that provides control of
lights throughout a home. Master Controls can be wall mounted, tabletop, or cordless. Other
system Master Controls are the Switch Closure Interface, the Infrared Interface, or the RS-
232 Interface.
Master Control Number -
Master Control Numbers are used to identify
RadioRA
Master
Controls via the RS-232 port on the Chronos
TM
System Bridge.
Phantom Buttons -
Phantom Buttons are “virtual” buttons in the
Chronos
System Bridge.
Though there are no physical buttons that represent these Phantom Buttons, they work very
similarly to buttons on
RadioRA
Master Controls. Each Phantom Button can be assigned
either as a ROOM or SCENE.
Phantom LEDs -
Phantom LEDs are “virtual” LEDs in the
Chronos
System Bridge. Though
there are no physical LEDs that represent these Phantom LEDs, they work very similarly to
LEDs on
RadioRA
Master Controls. Phantom LEDs 1–15 are associated with Phantom
Buttons 1–15, respectively.
ROOM Button -
A ROOM button is a programmable button whose LED is ON when any light-
ing zone assigned to that button is ON at any level. When issuing an “ON” command, a
ROOM button may only turn zones ON, not OFF.
SCENE Button -
A SCENE button is a programmable button whose LED is ON when the
SCENE associated with that button has been activated. The LED will go out when the light
zone changes level or receives a command to change level, even if the new level is the same
as its preset level. The LED will also go out if the SCENE is turned OFF. When issuing an
“ON” command, a SCENE button may turn zones ON or OFF.
Zone -
A zone is any individual
RadioRA
Dimmer, Switch, or GRAFIK Eye
®
Interface. A
RadioRA
System has a maximum of 32 zones.
Zone Number -
Zone Numbers can be used to identify any individual zone (one Dimmer,
Switch, or
GRAFIK Eye
Control Unit) in your
RadioRA
System via the RS-232 port on the
Chronos
System Bridge.
Zone Control -
A device that controls a zone of lighting or a shade, such as a Dimmer,
Switch, or
GRAFIK Eye
Control Unit.
