Do what I do. On my invoice, I write the following:

"My license, insurance and reputation depend upon my doing a professional job.

"Please be advised that as of this date, I have inspected the telephone wiring in your (home) (business) and I have found the following violations:

"Alarm wires were installed in a non-standard/illegal/dangerous way. In the event of an alarm, there was the possibility that the alarm message would not have been transmitted correctly, if at all. I have corrected the violation, to protect your property.

"If you have any questions about the wiring I corrected, please have your alarm company representative contact me."
