Abstract
An alarm system includes plural customer sites and first and second alarm monitoring stations. Each customer site has an alarm communicator for calling a monitoring station and transmitting an alarm message. The first and second monitoring stations are provided for receiving the alarm message through a telecommunications network. Each monitoring station includes an alarm processor system for processing the alarm message. Alternate routing in the network allows an alarm call to be rerouted from the first monitoring station to the second central monitoring station if the alarm call to the first station cannot be completed.
