|What’s Wrong With This?|
A technician installed a reader next to the door so that it was easy to present his authorization credentials and enter the facility. However, he was getting intermittent readers and many denials when proper credentials were presented. What did he do wrong?
The technician installed the reader and the reader wires too close to the electric wires controlling the light switch, which was causing interference on his reader. This is also a code violation because he didn’t keep proper separation of the light and power circuit from the Class 2 low-voltage circuit.
