SAT8 Hot-Standby Alarm Tone Generator System


  • System on a chip technology
  • Supplied fully configured
  • Complies with international standards


For highly critical voice alarm broadcast applications (PA/GA) it is essential to provide redundancy of critical hardware to improve overall PA/GA system security. PSC VODEC SAT8 is a compact plug in/out module designed to operate in conjunction with PSC VODEC VX/AT-M PA/GA management switch. The SAT8 is a self-contained alarm tone generation sub-system that can be configured to provide back-up to the host VX/AT-M alarm generation package on a “hot-standby” N+1 basis.

When N+1 alarm tone generation is required the SAT8 is plugged into the host VX/AT-M motherboard which is then configured to recognise the additional hardware by simple on-board DIL switch/plug link selection. The SAT8 can be arranged to supply alarm tone signals as the primary source (i.e. on-line) with the host alarm generation sub-system on hot-standby or the SAT8 can be a slave back-up tone source. Preference is set by tamperproof plug linking.
