System description and installation
CA-64 SATEL
Each module connected to the bus should have its own, unique address. It has no
meaning, which addresses are set for individual modules (the control panel receives
an information on module type and automatically sets optimum sequence of calling
the modules for data). Address is set by means of switches marked ADDRESS
ABCDE.

PANEL
Fig. 17. Connection of module group located far from the control panel.
The control panel services the modules registered in the system by means of the
service mode function
Identification of expanders
. This function determines
expander addresses and types. Additionally, it defines a special random generated
marker, with which the module confirms its presence in the system. This marker is
stored in module non-volatile EEPROM memory, and it may be changed in a next
identification process only. Therefore, each module replacement, address change
and change of module type under given address require running of the identification
function again.
NOTES
• The control panel does not service the modules when the identification function is
not completed with message “X modules found”.
