Bosch PRA-APAL Advanced Public Address License

The Bosch PRA-APAL Advanced Public Address License is a license code for an operator device to access the advanced public address server PRA-APAS for PRAESENSA. The Bosch PRA-APAL adds advanced business-related public address functions to the function set provided by the system controller. A PC or wireless tablet, connected to the local IP network, functions as an operator device with an intuitive graphical user interface, controlled by a mouse or touch screen. A headset, connected via USB or Bluetooth to the operator’s device, may be used for voice announcements and audio monitoring. The integrated web server of the Bosch PRA-APAS Advanced Public Address keeps the operator device platform independent. Each operator device uses its own web browser as the operator interface (Chrome preferred).

Advanced Public Address License

• License for an operator device to connect to the PRA-APAS advanced public address server.
• Multiple operator devices may access the advanced public address server simultaneously, each using its own PRA-APAL license.
• Each license of an operator device may have multiple, different, operator profiles on that device, with tailored functionalities for each user group.

Operator Functions

• Easy zone selection with a picture representation of zones.
• Control of background music sources and volume levels in selected zones. Music can be streamed from internal memory, but also from Internet music portals and Internet radio.
• Live call recording of announcements with pre‑monitoring and playback to selected zones.
• Live and scheduled playback of stored messages.
• Playback of text-based announcements with automatic (multi‑lingual) online text‑to‑speech conversion.

Public Address Server

• Industrial PC with pre-installed and licensed software, acting as a server to one or more operator control devices, and as an interface between these devices and one PRAESENSA system.
• For security reasons, the server has two ports to connect to two different local area networks. One port is connected to the secure PRAESENSA network, and the other port is to the corporate network with access to operator devices and (firewall-protected) access to the Internet.
• License management of operator devices. Each operator device needs a PRA-APAL license for access to the advanced public address server.
• Integrated web server to keep operator devices platform independent. Each operator device uses its own web browser as the operator interface.
• Storage of messages and music in internal memory, multiple audio formats supported.
