Exam Questions and CORRECT Answers
Convenience Energy efficiency System control - CORRECT ANSWER - A building
automation system can have a large impact on a building by providing?
Wiring interconnections Block diagrams - CORRECT ANSWER - What Illustrates both
signals and power wiring for each panel and device including information on power sources.
Motor controller - CORRECT ANSWER - A VFD ____ is used to change the speed of an
AC motor by changing the frequency of the supply voltage
Variable Frequency Drive - CORRECT ANSWER - What can control: motor acceleration
time, motor breaking, motor deceleration time, motor speed, motor torque.
Transient voltages - CORRECT ANSWER - What are caused by lightning strikes,
unfiltered electrical equipment, contact bounce, arcing, and high current loads being switched on
and off
HID Lamps - CORRECT ANSWER - High pressure, low pressure, mercury vapor, metal
halide.
Microwave Passive infrared Ultrasonic - CORRECT ANSWER - What technologies are
used in occupancy sensors to sense people within a space?
Infrared - CORRECT ANSWER - What type of occupancy sensor activates when it senses
the heat energy of people within its field of view
Phototransistors - CORRECT ANSWER - More common than photoresistors because
silicon is the better option. These also replace failed photo resistors
