I have a rather large layout for my ELK M1 system with a remote area containing several keypads and zone expanders. Daisy chaining the keypads in this remote area will be next to impossible so a ELK-M1DBHR Date Bus Hubs would be the perfect solution. However, the ELK-M1DBHR will be around a 150′ wire length from the M1 control board and the instructions for the ELK-M1DBHR specifically state to NOT mount the hub remote from the M1. These keypads will also need to have their own power supply (the ELK-P212S) and wired according to the diagram in the hub’s instructions. What is the issue with remotely mounting the Hub from the main control board?
The M1DBHR Dat Bus Hub Retro Fit has 4 RS485 Data Buses and there is a tremendous about of data all of which requires specific timing going from each Branch to the M1. It is our recommendation the wiring from the M1DBHR be as close to the M1 as possible. Each Branch of the M1DBHR can support longer data bus runs so could have the M1DBH in the remote area and wire each device in the remote area using CAT5/6 to the M1DBH. Use the P212S to power the M1DBH but Do Not Connect the +12V from the M1DBHR to the M1DBH — will only need Data A, Data B and NEG.
