BOSCH PRS-CSM Call Station Module (replaces LBB4433/00)

The BOSCH PRS-CSM is a professionally designed call station module that is used for making custom-made call stations, that comes along with the same functionality as the LBB 4430/00 Call Station Basic. The module is powered from the Praesideo network, but an external power supply is also possible to be connected. Two supervised control inputs are capable of accepting power supply status information from the external power supply. The PRS-CSM is capable to be extended along with up to 16 keypads (LBB 4432/00 or PRS-CSKPM), each comes along with eight programmable keys. Extension that comes with a numeric keypad (PRS-CSNKP) is also possible.
