This card is used as a supervisory card for remote microphones within the Potter EVAX voice evacuation system
One EVX-SC card is required per system. It supervises up to five remote microphones, ensuring each remote mic is properly monitored for faults or failures.
It is an essential component for remote paging microphones with the EVAX voice evacuation panel, often required in large buildings where emergency communications may be needed from multiple locations, such as lobbies or security stations
