Transformer replacement
If you have confirmed there is a transformer failure, there are two
options for transformer replacement. You can either use a plug-in
wall-wart style transformer or wire a new transformer into the
home's mains lines, physically replacing the existing transformer (a
professional electrician is recommended for this installation).
If you choose the first option, you can use an AC-AC Wall-Adapter
transformer like those commonly used to power security panels.
Next, identify a power outlet near the existing transformer. Remove
the low-voltage wires from the existing transformer and connect
those wires to the new transformer. Plug the new transformer in to
the power outlet and secure it in place.
