An emergency notification system (10) using selective call communications techniques is provided for communicating human and property safety information to and from recipients scattered over wide geographic areas. A computer controlled head end communications interface (12) adds subaddress information to a message to target intended recipients. A media router (38) directs the message through appropriate transport media in accordance with the address information. Preferably, the messages are communicated, at least in part, over existing paging systems. Additional transport media include existing power distribution networks, twisted wire pairs and fiber optics networks. Bi-directional reporting capability is provided. The system is well-suited for the communication of emergency notifications and warnings. |
