This APIC interfaces a Command Module, Stratos-HSSD 2 or Stratos-Micra detector to an Apollo addressable loop. Up to 126 detectors can be monitored via a single APIC in a Command Module.
Fire 2, Fire 1, Pre-Alarm, Aux and Fault are signalled.
The Apollo protocol only defines two alarm levels and Fault as standard so panels may need custom software to support the other levels.
