The ELK-AEDBHR is an "active" RS-485 data bus hub designed for jobs where an Alarm Engine Control is retrofitting an older panel that has multiple homerun 4-Conductor Keypad / data wires. It splits the main 485 data bus into 4-managed 485 branches. Each branch can have 2-parallel home run cables for a total of 8-Home runs. The AEDBHR is designed with terminating jumpers for each branch. These jumpers, when appropriately paired with terminating jumpers on end-of-line devices, ensure proper operation and supervision.
