August 24, 201510 yr My wireless home alarm system has been jammed by source unknown. I have reset it but would like to back it up with hard wired system, not susceptible to jamming, for the upper floor of my house.Could you suggest components for such a system. I would like it to includeTwo PIRs (no need for pet friendly type)A remote wired keypad which can be set/unset easily without keying in a four number code ( I would like to either press one button or use a proximity tag, unless its operation can be jammed)A panic button (unless its operation can be jammed)Outside bellbox with battery back-up (not Odyssey)Thanks
