The microphone call stations are the appendix and external devices of the Proevac system.
Through the microphone stations is possible to control the recorded message players, both alarm or generic, and speak live messages,
over the selected zones.
Depending on the model, the user can access advanced and flexible features, typical of a public address system.
All units carry onboard indicators that report the status of the system.
All features, assignments and access to the zones are defined during the configuration of the system with the BEST software.
This section discusses the common features to all models and their specific functions.
