BOSCH LBB 4430/00 Call Station Basic Specs:

The call station basic can make manual or prerecorded announcements to any pre-assigned zones. The call station basic has a microphone on a flexible stem, a push-to-talk button, a speaker and a headset socket. The LBB 4430/00 can be extended with up to 16 keypads (LBB 4432/00 or LBB 4434/00), each with eight programmable keys. Extension with a numeric keypad (PRS-CSNKP) is also possible. The call station has a cardioid, supervised microphone on a gooseneck stem with good speech intelligibility.

A limiter and a speech filter improve intelligibility and prevent clipping of the audio. It has a volume control for the monitoring speaker and the headset. When it plays a chime or a pre-recorded message, the call station activates its speaker. When a headset is connected, it replaces the microphone and speaker. The call station has its own DSP and converts between analog and digital audio. The audio processing can include sensitivity adjustment, limiting and parametric equalization.

Up to 16 call station keypads can connect to the station via a serial communication link. The station provides the power for the keypads. Up to 224 priorities can be assigned to the call station. All configuration can be done via the Praesideo network controller. The call station is fully supervised and supports failsafe operation. Even if the Praesideo network controller fails, the call station is still able to put through emergency calls.
