Years ago when I was an alarm guy I had a building on 35th Street that was constantly hit by lightning and thus burning my alarm panel out. I did everything in the manufacturer recommended to earthing diodes and surge suppressors and the like ,nothing worked. A conversation with a telephone person resulted in the solution. This was in the day when the alarm systems were tied to the phone line. He told me just to tie a simple knot in the telephone cable tying my alarm to the phone, on the basis that it would slow down the surge so that it could ground elsewhere. I went from replacing the alarm control every 8 or so months to not having to ever replace it again for the next 3 years.
