System and method for monitoring security at a premises using line card

摘要

A security system includes at least one audio sensor and alarm panel, each located at a premises and generating alarm report data through a communications network to at least one alarm receiver located at a central station remote from the premises. 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. A line card is operable for receiving non-regulated alarm report data that is not regulated in accordance with Underwriter Laboratories 1610 requirements and establishing a bi-directional link for the non-regulated alarm report data between any central station automation system and the alarm panel at the premises until the bi-directional link is no longer required.
