The LBB 4438/00 Call Station Remote with the same functionality as the basic call station LBB4430/00, but it uses CAT-5 cable for its connection to the Praesideo network. It connects one-to-one to the call station interface LBB4437/00, which is part of the optical Praesideo network. The CAT-5 cable, carrying digital audio and control data, can be as long as 1 km. The length of the CAT-5 cable extends the span of a Praesideo network considerably. The LBB4438/00 can be extended with up to 16 keypads LBB4432/00 or LBB4434/00, each offering 8 configurable keys. The remote call station is powered by the call station interface via the CAT-5 cable, but a local power supply connection is also provided for long distance use with many keypads. The remote call station is fully supervised and complies with IEC60849. Even in the case, the Praesideo network controller would fail, the remote call station is still able to do emergency calls.

There are four types of power amplifier units in the Praesideo product range. These differ in the number of amplifier channels per frame and the power ratings of the individual amplifier channels.

The types of power amplifiers are as follows:
  • LBB 4421/10 1 x 500 W Power Amplifier
  • LBB 4422/10 2 x 250 W Power Amplifier
  • LBB 4424/10 4 x 125 W Power Amplifier
  • LBB 4428/00 8 x 60 W Power Amplifier

The power amplifiers are equipped with amplifier monitoring and change-over relays. The amplifier provides short-to-ground and short-circuit detection functions. If an end-of-line supervision card is plugged in, the loudspeaker lines are also monitored for open circuits. The pilot tone for the monitoring is generated by the power amplifier itself. The power amplifiers are equipped with audio processing facilities for each amplifier channel. The power amplifiers can be connected to the network line directly. Ambient microphone connection enables output level adjustment for maximum intelligibility.
