    • A security system includes at least one audio sensor and an alarm panel that transmits alarm report data through a communications network to at least one alarm receiver located at a central station remote from the premises that receives the alarm report data transmitted from the alarm panel through the communications network. A line card receives the alarm report data. An alarm receiver processor receives and processes regulated alarm report data in accordance with Underwriter Laboratories 1610 requirements. The line card is operable for receiving non-regulated alarm report data that is not regulated in accordance with Underwriter Laboratories 1610 requirements. The line card includes a secondary communications channel interfaced to a central station automation system and routes the regulated alarm report data to the central station automation system over the secondary communications channel and bypasses the alarm receiver processor.
