Overview
|
- Hub for connecting additional keypads or zone expanders to M1 and M1Gold panels
- Provides up to nine data bus connections and can be cascaded for more
Essential Info
Manage the data bus 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 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 data bus 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.

More Info
|
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; RJ 45 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.
