ELK M1DBHR M1 Data Bus Hub for Retrofit

An active RS-485 data bus hub engineered for retrofit installations where modern controls replace legacy panels with multiple 4-conductor keypad and data wiring runs. This hub intelligently splits the main 485 data bus into 4 managed branches, accommodating up to 8 home runs total—with each branch supporting 2 parallel cables. EOL termination on every branch guarantees proper operation and signal supervision. Ideal for preserving existing wiring infrastructure while upgrading to current control systems. Includes mounting rails for structured wiring boxes and supports daisy-chaining up to 2 units per control. Simplifies retrofit projects by eliminating costly rewiring while maintaining full system reliability and performance.
