Sur-Gard SG-DVL2A-ULC-SGDVL2A Digital Line Card Module

The Sur-Gard SG-DVL2A-ULC-SGDVL2A is a DVACS network line-card module for Sur-Gard SG digital central-station receivers, designed to plug into a CPM2 central processing module to monitor DVACS subscriber lines. Each SG-DVL2A module contains two line cards, providing two DVACS lines per module; with additional DVL2A modules, a CPM2 system can monitor up to 14 DVACS lines. The module is UL-listed for commercial fire and burglary systems and is listed for UL (AA) and ULC Level 3 configurations. In SG-MLR2-DV deployments, the SG-DVL2A serves as the DVACS line-card component of a multi-line receiver, interfacing with SG-MLR2-DV receivers to transport subscriber data using Sur-Gard protocols.
