ELK M1DBHR M1 Data Bus Hub for Retrofit

Designed for technicians and integrators who need fast, reliable retrofits, the ELK Products M1DBHR M1 Data Bus Hub for Retrofit lets you reuse existing 4-conductor keypad/data wiring to modernize legacy alarm systems. This active RS-485 data bus hub splits the main M1 data bus into four managed branches, each accepting up to two parallel home runs (up to 8 total), so you can retain multiple homerun runs without costly rewiring. EOL termination on every branch delivers supervised communications for dependable alarm monitoring and security system performance. Compact indoor construction and included mounting rails for ELK structured wiring boxes speed installation and keep panels organized. The M1DBHR is RoHS compliant and integrates seamlessly with M1Gold and M1EZ8 controls to support alarm communicator modules, surveillance interface points, and other security network devices. Reduce install time, preserve customer infrastructure, and maintain robust RS-485 communications across your site.
