What’s Wrong  With This?

A technician was pre-wiring a house for security, audio and other low-voltage systems.    When the building inspector arrived, he “red tagged” the installation after looking at how the technician ran the wires. What did the technician do wrong?

What's Wrong with this?




1.         b

2.         d

3.         b — If the control panel has a grounding screw then it is required to be grounded.

4.         b

5.         c — A dedicated circuit is best, but in a residence most outlets will be of the 24-hour type.

6.         d

7.         c — Adding two batteries in parallel doubles the amperage and therefore the standby time.

8.         d

9.         b — Motion detectors help add protection should the perimeter be breached.

10.       b — Improperly overloading a control panel is a major cause of false alarms.

11.       a — Burglar alarm signals are normally verified, so that will tell you if you aren’t properly on test.

12.       d

13.       e

14.       c — For every four feet of rise, the ladder should be one foot away from the wall.

15.       c
