Figure 6.1

Figure 6.2

The Plena Call Stations must be used in combination with the system pre-amplifier LBB 1925. Both call stations

have a loopthrough connection to add an additional call station. The 6-zone call station (LBB 1946) has the

possibility to send a message to one zone, a group of zones or all zones. The all-call call station (LBB 1941) can only

send a message to all zones.
