ELK Products ELK-M1DBHR M1 Data Bus Hub Retrofit
Overview
The ELK-M1DBHR is a data bus hub module designed to expand communications on ELK M1 control panels in retrofit installations. It serves as a centralized expansion point for daisy-chaining additional M1 data bus peripherals — keypads, sensors, output modules, and other bus-connected devices — without requiring separate wiring runs back to the main panel. This is the right choice when your retrofit scenario involves distributed zones across multiple rooms or floors and you need to reduce installation labor by consolidating runs at a secondary hub point.
Compatibility
The ELK-M1DBHR works with ELK M1 control panel retrofits. Verify your specific M1 firmware version and panel configuration with ELK's technical documentation before ordering, as retrofit compatibility depends on your existing system build and any prior hardware revisions.
Installation Notes
Mount the hub in a central location on your retrofit run — typically in a utility closet, junction box, or equipment room — where it can access power and connect to the M1 data bus line. The device consolidates multiple branches of the data bus, reducing the number of individual conductor runs required back to the panel. Ensure adequate spacing and strain relief on all data bus connections to prevent signal degradation over longer retrofit distances.
