Siemens (Pyro) ASC-2-RC

The Siemens Pyro ASC-2 Audio Supervision Card provides intelligent monitoring of amplifier output signals in MXLV intelligent voice communication systems. The card supervises one primary and one backup amplifier, automatically switching to the backup amplifier if the primary unit fails. Multiple ASC-2 cards can share a single backup amplifier, and the card integrates with the Siemens MXL voice system architecture to ensure reliable voice evacuation capability during emergencies. Address assignment and audio riser selection are configured via DIP switches.
