Has anyone used the Valcom VIP-801A Networked Page Zone Extender? I'm looking at using a pair of them to connect the page horns at an off site building, about 1.5 miles away from the main system. I'll use local power, of course, to power the horns. Going to also use a pair of Patton CL1314/EUI LAN Extenders also.

Thank you.
Jim
