Group Muting
In order to avoid acoustical feedback it may be desirable in certain
circumstances to mute speakers associated with adjoining stations when
making a paging call. This can be accomplished by interconnecting the “Group
Mute” terminals of each station in the group, and setting the speaker mute
jumpers on the circuit boards to the appropriate position.
See: Figure 5 - Electrical
Connections
Note: Putting the mute jumper of a station in the on position will mute the
associated speaker when the page button is pressed. If the jumper is in
the off position the speaker will not be muted when the page button is
pressed.
If group muting is used the associated speaker of any station in the group with
its mute jumper in the on position will be muted when a paging call is made
from any station in the group, including the associated station. Any speaker
associated with a station with its mute jumper in the off position will not be
muted when a paging call is made from any station in the group, including the
associated station.
Note: Paging calls
originating from stations
outside the group will be
heard regardless of the
position of the Mute
jumper.
If it is desired to bypass a station in a group, connect the group paging wires to
the PARK terminals of that station.
EXAMPLE OF GROUP MUTING
STATION "A"
PARK
SIGNAL CONDUCTORS
GROUP MUTE
OFF
STATION "B"
MUTE
JUMPER
MUTE
ON
STATION "C"
If the Group Mute Signal Conductors of station “B” are attached to the Park terminals, that station will
be bypassed and paging from stations “A” or “C” or any other station in the system will always be heard
over the loudspeaker associated with Station “B”, regardless of the position of the Mute jumper.
If the Group Mute Signal Conductors of station “B” are attached to the Mute terminals the condition of
the loudspeaker associated with that station will depend on the setting of the Mute On/Off jumper. If
the jumper is in the ON position the loudspeaker will be muted if a paging call is made from any of the
three stations. If the jumper is in the OFF position the paging call will not
be muted if a paging call is
made from any of the three stations.
Paging calls from outside the Group will always be heard, regardless of the position of the mute jumper.
