Silent Knight 6815 SLC Loop Expander

The 6815 is a signaling line circuit (SLC) expander for use with Honeywell Silent Knight 6820 or 6820EVS fire alarm control panels (FACPs)using System Sensor® (SK) protocol. The 6815 signaling circuit has the same functionality as the SLC that is built into the 6820 and 6820EVS panels and support the same addressable devices as the one in each panel. The number of 6815 SLCs that can be used within one system is largely dependent on maximum available points. They provide a powerful way to customize configurations in large or complex installs.
