4.3 Connect the call stations
Figure 4.3
You can connect 2 Plena Call Stations directly to the system pre-amplifier. To connect up to the maximum of 8 call
stations you must use a loop through connection. The loop through can contain both types of call stations.
4.4 Connect an emergency input line
Figure 4.4
You can use this input for emergency announcements and/or signals. This channel has the highest priority and is
always transmitted to all zones. The emergency line has it's own volume control on the rear, this volume is not
affected by the master volume. If a priority microphone, call station, emergency input or trigger input is activated,
the Call Active relay is closed and the override contacts of the selected loudspeaker zones are activated.
