Start here:
Check the obvious: loose wiring at the transformer, transformer fitting
loosely in the outlet, transformer wire damaged by contact, abrasion,
rodents, etc.

The outlet itself may be faulty, or the electrical connection behind it, or
there may be trouble elsewhere on that circuit.

You may have a faulty circuit breaker.

Unplug the transformer and use an extention cord to temporarily connect it
to a known good outlet.

Plug a lamp in there the transformer was. Wiggle the plug around and see
what happens.

Try a new transformer.

Upgrade to a real alarm control panel.














Just kidding.
