Abstract: An alarm communicator system has the capability to restore a Wide Area Network (WAN) connection to a remote alarm monitoring center. The system includes an alarm WAN communicator for communicating an alarm signal to a WAN gateway; a WAN outage detector for detecting a WAN outage condition; a power interruption signal transmitter connected to the alarm WAN communicator; a power interrupter unit connected between a WAN gateway power source and the gateway; and a power interruption signal receiver connected to the power interrupter unit. The system can transmit a power interruption signal through the power interruption signal transmitter after detection of the WAN outage condition. The power interrupter unit disconnects and then reconnects the power supplied from the power source to the gateway after receipt of the power interruption signal so as to cause the WAN gateway to power down and restart after the power supply is reconnected.

Abstract: The present invention provides a redundant data path system for transmitting an alarm signal between a monitored facility and a destination facility, said system comprising: alarm signal receiving means adapted to receive the alarm signal; destination facility identifying means adapted to identify the destination facility to which the alarm signal was directed by the monitored facility; destination facility monitoring means adapted to determine, at regular intervals, whether the destination facility is able to receive an alarm signal, either directly from the monitored facility or at all and alarm signal transmission means adapted to selectively transmit the alarm signal either to the identified destination facility, when said monitoring means indicates that the destination facility is not able to receive said alarm signal directly from the monitored facility, or to an alternate destination facility, when said monitoring means indicates that the destination facility is not able to receive said alarm signal at
