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.
