Question 21

this is something and how it works… What is it?

a.DEF: Turns lights on and off at designated times
b. Simple device which can be set manually and plugs into a wall socket, or a component in computer program
c. They can even detect sunrise and sunset time through the seasons as well as daylight savings
d. This allows lighting functions to be programmed to reliably activate at certain time of the day throughout the year
e. Save energy by using in closets, attics, basements, and other low-traffic areas to ensure the light is never left on for a long time
f. It allows lighting functions to automatically occur at a specific time throughout the day

Answer 21

Control systems/timers

Question 22

Answer 24

1. intelligent lighting control panel
2. control divices
3. group luminaires

Question 25

Why do we like Localized Control Panels? | there are 5 things

Answer 25

a.Control up to 6 light loads b. Reduces# of traditional light switches ( dimming and scene abilities) c. Energy Conservation d. Economics e. Aesthetics

Question 26

How do we want to work through the design process | 3 main things

Answer 26

**1. Identify these lighting loads** i. Those that need to be controlled from many locations ii. Commonly / complexly dimmed loads iii. of pre programmed scenes / automated / time-clocks **2. And then switching** i. Loads that need only simple local switching, simple dimming. **3.This tells you what level control system is appropriate**
