The Centaur ASE has a built-in modem for connection to an ordinary telephone line. The installation of a telephone line is required for standard compliance. The telephone line serves as a backup (secondary link) to the Radio (or primary) connection.
The backup fire line dials daily to a “1300” number as a test dial to ensure the line is permanently connected. In case of radio link fail, the backup fire line will dial the 1300 number again to make sure at least one link is available.
The telephone line must be a dedicated fire line, used only for Fire Alarm Monitoring purpose, because it will detect the loss of the line each time it is used for other purpose, and report this as a PSTN fault.
