The PVA-CSK call station kit is a call station printed circuit board (PCB) for the PAVIRO system. The circuit

board allows an application-specific call station to be installed, such as a fire department call station.

The call station kit is based on the call station, but has been optimized so that it is easy to adapt to different application areas. In addition to the stem microphone that is used with the PVA-15CST, a dynamic EMERGENCY microphone such as the LBB 9081 can also be connected.

The call station kit is equipped with an illuminated LC display (122 x 32 pixels). The call station has the

following features:

• Possible to connect microphone with pre-amplifier and compressor/limiting switch
• Possible to connect five pre-programmed menu/ function buttons
• Possible to connect up to 15 function and selection buttons, programmable button assignment
• Possible to connect up to three alarm buttons or key switches
• Possible to connect an external microphone or audio source
• Possible to connect a loudspeaker
• High-resolution LC display
• Comprehensive parameter settings menu on the actual call station
• Microphone and line monitoring
• Error message via LED and buzzer, and error text in the LC display
• Processor control of all functions
• Monitoring of the processor system via watchdog circuit
• Non-volatile FLASH memory for configuration data

The call station is processor-controlled, and equipped with extensive monitoring functions. Line monitoring for the CAN bus and for audio transmission allows line interruptions and short-circuits to be detected and indicated to the user. The microphone, PTT button, alarm button and key switch monitoring allows line interruptions and short-circuits to be detected and reported.

The call stations can be configured quickly and easily using IRIS-Net. A graphical and dialog-based user interface allows the user to define all button functions, priorities, options, and other properties.
