LOW VOLTAGE WIRE CUT

A. Have you had construction work done around the time your system stopped functioning. Workers in the attic. Someone may have accidentally cut or pulled a wire loose.
B. It is possible that you have rodents in your attic. Rats commonly chew through attic wiring. We have seen this quite a bit on the island of Palm Beach in multi-million dollar homes. Time to call in an exterminator.
C. Do you have a detached garage. Has there been digging between the house and garage?
D. Re-splice the broken wires. Make sure you attach copper to copper and tin to tin.
E. Re-route wires from a working inlet to the non-functioning inlet.
F. Install a radio-frequency remote on/off control system to activate your system without repairing cut wires.
