  • What's Included
  • Manage the databus wires in your M1 Gold or M1 Kit control panel with an M1 Databus Hub. When you're ready to expand your system and add more LCD keypads or zones, the M1 Databus Hub designed to makes connections easy. The M1 Databus Hub accepts up to nine RJ45-equipped cat.5 or cat.6 cables, and connects the data A & B lines to and from devices so the databus may be terminated properly. Looking to attach more than nine cables? No problem: two or more units may be interconnected if more than 9 data lines are required.



    The M1 Databus Hub is pre-assembled on a 3" structured wiring plate, which mounts inside the M1 or M1Gold panel. An RJ45 terminating resistor plug is included; RJ45 8 Conductor Plugs are sold separately. The M1, M1Gold, keypads and the 16 Zone Input Expander are all sold separately.

    The data A & B lines are connected to each device (keypad, zone expander, etc.) along with a "return" wire so that the data returns back to the M1 Databus Hub, which is then used to feed the next device. Effectively, this puts the data lines in a series circuit so that the control communicates with each device in a progression or "daisy chain" fashion, the end of which uses the included resistor terminating plug. This plug places a 120-Ohm resistor across the A & B data return lines coming from the last wired device, effectively terminating the bus.

    If you have multiple keypads, this item makes installation much easier. It essentially changes the wiring layout from daisy chain to star, allowing direct runs from the main panel to each keypad. Also works with the Elk wireless expander.

    Easy to install and makes adding multiple keypads a breeze. You can use this to add zone expanders also.
