If we don’t receive an answer, the police or fire department are dispatched to your home and we continue calling the numbers on your call list. If we do receive an answer, we verify your password, and at that point you can decide if you want us to dispatch or not.

Smaller systems usually take 2 hours or less to switch over, while more complex ones with many zones will take more.
