CLCP study guide ( EE101-110 ) | QUESTIONS AND
ANSWERS
Which of the below color output strategies is possible with controlled LED lighting? **
Answers ** tune color output to produce any color
tune shade of white light to desired CCT
dim to a very warm CCT similar to incandescent dimming
Which of the below control strategies is enacted using a time clock, which may be a physical
device or more commonly implemented by a lighting controller? ** Answers ** scheduling
A control protocol is _____. ** Answers ** A set of rules that define the behavior of
components in a control system
Which of the below is NOT an example of a standalone control device? ** Answers **
Lighting controller
When it is said, "Lighting controls save energy by ensuring lighting is only used WHERE it's
needed," what control strategy is being referred to? ** Answers ** Reducing light level based
on daylight level or visual needs
A lighting controller is a ______. ** Answers ** A control input device
What is a distinguishing feature of a centralized intelligent lighting control system? ** Answers
** The system is programmed and controlled using software that resides on a central server or
the Cloud
Energy consumption, occupancy and potentially other data can be measured and stored for
analysis
,Luminaire/Zone status can be monitored, potentially with alarm notifications
The controls narrative provides ____. ** Answers ** Sequence of operations for each control
point in a control system
The sequence of operations for a control point defines _____. ** Answers ** What the
control point does in response to various inputs
Automatic lighting control is ideally suited to _____. ** Answers ** Energy management
Control zones may be organized by _____. ** Answers ** Energy code requirements
Daylight availability
Lighting schedules
What is a distinguishing feature of a networked control system? ** Answers ** Lighting
controllers are networked enabling addressable control points that can be grouped and
programmed
When it is said, "Lighting controls save energy by ensuring lighting is only used WHEN it's
needed," what control strategy is being referred to? ** Answers ** Automatic shutoff based
on occupancy or time of day
Which would be better suited for turning the lights OFF or reducing light levels in a classroom
when it is not occupied? ** Answers ** Switching
Which of the below control strategies is enacted using a light sensor (photosensor)? **
Answers ** Occupancy sensing
, Which would be better suited for turning lights OFF in certain areas or reducing light levels in an
occupied open office? ** Answers ** dimming
A lighting control zone is _____. ** Answers ** One or more light sources simultaneously
controlled by a single control output
Occupancy sensors may be specified as _____ devices. ** Answers ** full - ON
Occupancy sensors save energy by turning OFF the lights when the space is _____. ** Answers
** unoccupied
Line-voltage occupancy sensors do not require a power pack, which makes them suitable for
applications where there is no plenum or junction boxes are hard to access. However, they have
the disadvantage of _____. ** Answers ** Needing additional wiring, which can add cost
_____ occupancy sensors utilize a single detection method that involves sensing the difference
in heat emitted by humans in motion from that of the background space. ** Answers ** PIR
Ultrasonic sensors generally cannot see around objects because they require a direct line of
sight to the person being detected. ** Answers ** true
Ultrasonic sensors have the highest sensitivity to motion when the person is moving [u]. **
Answers ** Laterally to the sensor
PIR sensors have the highest sensitivity to motion when the person is moving _____. **
Answers ** to and from the sensor
We need to choose an occupancy sensor for an application that features obstacles such as
partitions. Which sensor would be appropriate? ** Answers ** ceiling mounted
