Some surges come in via other routes, most often the power line. So you want to stop those before they hit the equipment. Makes more sense when you have a coax surge arrestor on the outside of the building and an AC surge suppressor on the power input of the same system. A bit redundant when all you have is CAT5.

Yes as they will qualify to do both jobs, but you still need two of them to be in compliance with R56. From: Adam Moffett Sent: Friday, December 1, 2017 3:00 PM To: [email protected] Subject: [AFMUG] McCown Tech surge question This is a question from McCown: I've pasted in a little snip from the 2005 Motorola R56 book. With the "belt and suspenders" design approach you've mentioned in the past, would it be fair to say that your products would qualify as both a primary and secondary protection device as defined herein?
