DSC MX920 Addressable MX Digital Loop Line Isolator Module

Keep your security and surveillance systems operational even when wiring faults occur with the DSC MX920 Addressable MX Digital Loop Line Isolator Module. Purpose-built for IQ PRO control panels and MX addressable loops, the MX920 detects short circuits and isolates only the affected section so the remainder of the addressable loop continues to monitor and report events without interruption. That translates to less downtime, fewer service calls, and sustained protection for critical commercial installations.

The MX920 installs neatly in a standard dual‑gang MK box and features a yellow LED for immediate visual confirmation of unit status — simplifying field diagnostics and routine maintenance. As part of DSC’s MX series (Manufacturer Part Number MX920), this isolator module delivers dependable short‑circuit detection and sectional isolation to protect alarm panels and connected devices. Ideal for security integrators and facility managers, it supports uninterrupted alarm monitoring, rapid fault containment, and robust system resiliency.

Add the DSC MX920 isolator to your control panel modules to enhance uptime and simplify troubleshooting in security and surveillance installations — contact your supplier or order now to upgrade loop reliability.
