The Simplex 4100-6415 is a DSL retrofit harness for Simplex 4100-series fire alarm control panels. First, it provides the cable assembly needed when upgrading or replacing DSL-related boards in legacy 4100 installations. Then, it routes signals between the new and existing panel hardware without rewiring the field circuits.
Service technicians order the 4100-6415 when retrofitting an older 4100 panel rather than replacing the entire cabinet. As a result, the harness lets the existing wiring infrastructure remain in place while supporting the upgraded boards.
