LBB 4410/00 Network Splitter
 The network splitter is used in a network to provide two branches from the main cable run. It can use an external DC power supply, or it can use the power supply from the network controller. The unit automatically switches to the local power supply unit when it is connected to it, reducing the power drain on the main network.

LBB 4414/00 Fiber Interface With Full Address
The unit interfaces glass fiber optical cable with plastic fiber optical cable, and supports redundant wiring topology.
|
 | |
LBB 4414/10 Fiber Interface Without Address
The fiber interface is used in conjunction with the system installation to convert from plastic optical network cable to glass optical fiber and vice versa.

LBB 4440/00 Supervision Control Board
The board controls the communication between the Praesideo system and the loudspeaker or loudspeaker line supervision boards. The LBB 4440/00 is the supervision control board, monitoring multiple supervision-slave boards (LBB 4441/00 and LBB 4443/00), which are mounted inside the loudspeakers on the line.
|
 | |
LBB 4441/00 Loudspeaker Supervision Board
The board monitors the integrity of a loudspeaker. It works together with the LBB 4440/00 Supervision Control Board. The speaker status is communicated to the LBB 4440/00 via the existing loudspeaker cable.
|
 | |
LBB 4442/00 Line Supervision Set
The Praesideo system uses a unique loudspeaker line monitoring principle, which requires no additional cable. The loudspeaker line itself is used to communicate with the supervision-slave installed at the end of the loudspeaker line. The LBB 4442/00 contains the master and slave device for supervision of a single loudspeaker line.
|
 | |
LBB 4443/00 End of Line (EOL) Supervision Board
The board monitors the integrity of a loudspeaker line. The boards work together with the LBB 4440/00 Supervision Control Board to monitor the status of the loudspeaker line and all of its branches. The line status is communicated to the LBB 4440/00 via the existing loudspeaker cable.

PRS–FINMO Fiber Interface
The PRS-FINMO is the same as the LBB 4414/00, except that it accepts monomode glass optical fiber instead of multimode glass optical fiber. However, this does not increase the maximum permitted cable length of a Praesideo network.
