Siemens (Pyro) OCC-1-RC

The Siemens Pyro OCC-1 Output Control Card is an MXLV audio output control module that manages voice zone cards and audio supervision functions in Siemens intelligent voice evacuation systems. The card plugs into the OMM-1 or OMM-2 Output Master module and serves as the control backbone for voice system audio zones, supporting multiple ASC-2 audio supervision cards. The OCC-1 provides 24 VDC system power distribution with monitored circuit supervision and maximum 20-ohm loop resistance specification for reliable voice circuit operation.
