It is extremely important that you test your security system monthly, you cannot afford to experience a communication failure with the Monitoring Station, in the event of a real emergency. The technology used depends on proper connectivity with your phone service provider, unless you employ "Cellular Back-Up" service. Reasons your service communication can fail:

 - You disconnected your home phone service (i.e.: Bell South land line). Many consumers are going to cell phone use only and forgetting the security system communicator is getting disconnected too, when the service is cancelled.

 -You changed your phone service carrier or type of service (i.e.: moved to VOIP). Many times these new service providers forget or cannot connect the communicator properly.

- Your current phone provider has frequent service outages. If your phone service is down, your communicator is down.
