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 familiar from the PVA-15CST , a dynamic EMERGENCY microphone such as the DBB 9081 can also be connected. The call station kit equipped with an illuminated LC display (122 x 32 pixels).
