Number and distribution of IB200 isolators.
To increase the reliability and the extension of the BUS, it is necessary to use isolators.
2.4 Flex5/R project
After installing the control panel peripherals and connecting them to the BUS, it is necessary to allow the
control panel to recognize and distinguish one from another in order for them to be placed in the con-
figuration.
This is possible firstly by assigning an address to each peripheral.
The addressing procedure changes in accordance with the type of peripheral. The types available are:
l
keypads (both with keys and LCD display and also with touch-screens)
l
proximity readers (both stand-alone and integrated into keypads)
l
expansions (both with input/output and relay terminals)
l
sounder/flasher
l
home-automation modules
l
thermostats
l
wireless transceivers
Warning
Peripherals of different types can have the same address, whereas peripherals of the same
type must always have different addresses.
Wireless transceivers must have different addresses from those of readers and expansions.
After assigning all the addresses, it is necessary for the control panel to carry out the peripheral enrolling pro-
cedures in order to include them in the system configuration that the control panel will manage.
