BOSCH LBB4430/00 Call Station Basic

BOSCH LBB4430/00 Call Station Basic

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

A limiter and a speech filter are improving the intelligibility and preventing the clipping of the audio. It comes along with a volume control intended for the monitoring speaker and the headset. During the time it plays a chime or a pre-recorded message, the call station is activating its speaker. During the time a headset is connected, it is capable of replacing the microphone and speaker. The call station comes along with its own DSP and is converting it between analog and digital audio. The audio processing are capable to include sensitivity adjustment, limiting and parametric equalization.

Up to 16 call station keypads are capable to connect to the station with the use of a serial communication link. The station is made for providing the power for the keypads. Up to 224 priorities are capable to be assigned to the call station. All configuration are possible to be done with the use of 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.
