The transistor outputs 1-8 are assigned in the delivery state with the functions of area 1 described in the table.
Note: Output 1 "Intrusion" switches with an intrusion alarm from all areas. Output 2 "Personal attack" switches
with an intrusion alarm from all areas. It can be reprogrammed (output address 0).
