The X2 terminal is used for wiring between the AAB-X22/X2 connection distributors. The as-
signment of the terminal option depends on the detector variant. For example, the Siemens
or Bosch fire alarm loop can be wired via terminals 10 to 13. Alternatively, the 2nd alarm relay
of the ADICOS detectors or the analog output signal of the ADICOS HOTSPOT detectors can
be tapped at these terminals.
