The DSC MX920 Line Isolator Module is used on IQ PRO panels. It connects to the MX addressable loop circuit of the HSM3105. The MX920 module is used to monitor for short circuits. If it detects a short circuit, it will isolate the affected section while allowing the rest of the addressable circuit to function normally. This module ensures that a single short does not disable the entire MX addressable loop circuit.
