Kidde V-SLC2-2 (500-Point Dual-Loop Controller Card, VS4 Series)

The Kidde V-SLC2-2 is a plug-in Signature loop controller that adds two Class B or Class A intelligent device loops to any VS4-series fire-alarm control panel. Board includes on-board isolation and automatic device mapping and supports up to 500 addressable points in total (125 detectors and 125 modules on each loop). A single card raises a VS4 panel from 250 to 750 points; installing it in a second expansion slot brings the panel to the series maximum of 1,000 points. The controller draws power and communications from the backplane and installs without disturbing existing field wiring or program data.
