3 NAVIGATING THE USER INTERFACE

EXAMPLE:
You might use a motion sensor to control the lights in a seldom used
warehouse. As someone opened the door, the sensor would notify the NorthStar
lighting system of movement and the system would respond by invoking a behavior
to turn the lights on. When the occupant leaves, the system could gradually dim the
lights to off over a specified time to ensure that no one is left in the dark.
Likewise, a NorthStar lighting system can respond to a lack of movement. When the
motion sensors within the warehouse have not sensed movement for a user defined
amount of time, the system can change the light level to something lower.
Behaviors is triggered by manual switches, motion detectors, and photocells.
For more information on Behaviors, see Adding Sensors on page 29.
What is a Scene?
A Scene is a grouping of Zones, with specified behaviors for each of those Zones.
This allows you to issue commands to a number of lights where each light is at a
different brightness or activation method.
Depending on the needs of your installation, you might have a scene for a normal
business day, an energy saver scene for evenings, or an emergency scene for
disaster drills.
EXAMPLE:
Within our theater example, we could have a number of Scenes available
to create different atmospheres. Two Scenes within a theater might be "Pre-Movie,"
and "Movie."
The "Pre-Movie" scene might set the overhead lights zone to 60% brightness so
patrons can find their seats, while the aisle lights and the above door lights zones are
set to 80% brightness to provide extra definition. When the "Movie" scene is invoked,
the overhead lights zone is reduced to off, while the aisle lights are dimmed to 10%
brightness, and the above door lights are reduced to 20% brightness.
