Abstract: An event notification system is linked to a plurality of event generation devices and to an event notification network. The system receives event messages from the event generation devices and determines what information should be included in an event notification message that the system transmits to one or more recipient devices. Each event notification message includes coded event message information and a coded unique message identity. A response message receive by the system from a recipient device includes the coded event message information which is used by the system to validate the response.
