Deck 8: Home Automation and Lighting Control

Question 1

Pulseworx uses a signal known as ____________________ to provide control data over AC wiring.

Answer 1

Universal Powerline Bus
UPB
Universal Powerline Bus (UPB)

Question 2

If only some circuits in the house are turned off, it is same to assume every outlet or fixture you are working on is off.

Answer 2

False

Question 3

Explain why systems with large electric motors is the one exception to the neutral effect of automation and how this can be remedied.

Answer 3

When starting, motors momentarily draw three or four times the current that they require when running at speed.Before automating an HVAC system, or any other system that includes a large electric motor, the electrical wiring for the system should be checked to be sure it has adequate power to prevent even temporary (startup) overload conditions.If necessary, a compensating device can be installed in the motor's circuit to reduce the startup surge of current drawn from the AC wiring so as not to adversely affect other equipment or the automation system.

Question 4

Describe some of the systems and functions X-10 systems can control.

Question 5

The first and still most common method of lighting control and automation uses X-10 power-line (PLC) technology.

Question 6

In home with more than 2500 square feet of floor space, an X-10 signal ____________________ may be needed both to strengthen the X-10 command signals and to eliminate noise from the signals so that they can be more easily understood by the receiving control modules.

Question 7

If a light is in two zones, it must have its own ____________________.

Question 8

An X-10 command module must connect to an electrical outlet in order to transmit its signals on the AC wiring.

Question 9

Discuss the functionality of X-10 remote-access control devices.

Question 10

Problems with automation systems come mainly from ____________________.

Question 11

One of the best advances in recent X-10 products is the development of ____________________ X-10 modules.

Question 12

Question 13

A home automation system will add load to the home's AC electric wiring.

Question 14

All the AC fixtures in the home should be ____________________, as should those installed as part of any new circuits added to upgrade the home's electrical system.

Question 15

Explain why the exterior security zone should be installed before the decorative lighting zone.

Question 16

For lights in a single zone, try to connect as many as you can in daisy chains to minimize the number of control modules you need.

Question 17

Differentiate between a lighting zone and a lighting scene.

Question 18

Describe how an X-10 socket module is used.

Question 19

Discuss how RadioRA command modules can be interfaced to a computer.
