Fig. 3. An example of interaction between two INT-FI units and communication buses of
INTEGRA control panel. The unit on the control panel side is configured as Master (M/S
jumper removed), and the unit on the keypad / expander side is configured as Slave (M/S
jumper set). The unit working on the control panel side can be power supplied from the
control panel main board. The other unit can be supplied locally, from an independent power
source (additional power supply unit, expander with power supply). The unit working in Slave
configuration can accept a larger number of connected keypads and expanders than shown
in the illustration above.
