32.5.1 Address
Each alarm card is addressed directly. On a typical 32Way SmartAlarm, rst alarm card data is
accessed using node address 1, second alarm card using node address 2 etc. As default the rst
node address starts at 1, this can be modied using the conguration software. Select View -
Advanced then Comms tab and adjust the eld marked “Comms Address Offset”.
First card Node Address = 1 + Comms Address Offset.
Second card Node Address = 2 + Comms Address Offset.
Third card Node Address = 3 + Comms Address Offset.
Comms Address Offset default is 0.

32.5.3 Error Check

Redundancy Check)
