BUS Connection
If the system has more keypads/repeaters other than the one inside the
main cabinet, they must be connected with the 4 wire bus. Each keypad/
repeater has a 4 way terminal block for this purpose. The correct connec-
tion is show in Figure 2. Take great care not to mix the data wires with the
power wires as permanent damage may be caused. Additional 7 keypads/
repeaters can be connected.
