Industrial SG-DVL-2 Alarm System Controller Module

The SG-DVL-2 (SGDVL2) Sur-Gard alarm system controller module is a two-line DVACS receiver expansion designed for Sur-Gard central monitoring systems. Each SG-DVL-2A module contains two line cards and interfaces with the CPM2 central processing module via the backplane, enabling multiple remote alarm lines to be received and forwarded to the central station. The DVACS-based interface is used in Sur-Gard System II and related SCADA configurations to connect field alarm transmitters to the central monitoring setup. This module expands a Sur-Gard installation’s capacity to manage multiple DVACS lines from dispersed sites within a single system.
