I really like working with your master box rather than others. It’s so easy to work with.
John P. Melfa Superintendent of Alarms Rutherford, NJ
I have been very satisfied with the performance of the solid state master boxes. I have installed several and found the installation and programming to be fairly easy. So far, they have been lightning resistant. Be sure to use their lightning protection and power supply for maximum protection. Questions have been answered promptly. A very good company.
