7.11.3 Latch disable
This function prevents talks to any label from latching. If a latch-disabled label is assigned
to a selector key, the key can only access the label for as long as the operator physically
holds down the key. A latch-disabled port’s label can be included in a fixed group or
partyline without automatically latch disabling the entire fixed group or partyline.
7.11.4 Local ISO
This function enables a panel or interface as a local ISO destination of the source panel or
interface. When the source activates a talk to any of its local ISO destinations, that talk is a
private, two-way path. All other talk paths from the source are interrupted. All existing talk
and listen paths between the source and the destination are interrupted, except for other
ISO talk paths. When the source terminates the talk, the destination’s audio paths resume;
when all ISO paths to the destination are deactivated, the destination’s audio paths return
to their previous states. If more than one panel activates an ISO path to the destination,
both sources can talk and listen to the destination. For ISO talks to also interrupt listens at
the source, check the ISO Interrupts All Other Listens box in the Matrix Preferences ISO
and IFB tab.
Note: If the destination of an ISO is a panel then Eavesdropping must be enabled in Global
Settings (Advanced Settings section) in order to activate the panel microphone if it is not
already activated. If the destination is not a panel but a device such as a four-wire port
Eavesdropping does not need to be enabled for the destination device.
7.11.5 Local IFB
This function enables a panel or interface as a local IFB destination of the source panel or
interface. When the source activates a talk to one of its local IFB destinations, that talk is a
private, one-way path. All existing talk and listen paths to the destination are interrupted,
except for other IFB talk paths. When the source terminates the talk, its audio paths
resume. When all IFB talks to the destination are deactivated, the destinations audio paths
return to their previous states. If more than one panel activates IFB talks to the same
destination, both sources are heard by the destination. For IFB talks to also interrupt talks
at the source, select the IFB Interrupts All Other Talks From Source Panels button in the
Matrix Preferences screen from the System screen.
Note: The level of the interrupt can be set using Local Advanced.
7.11.6 Route monitor
Enable monitoring of an audio route. This creates a key that is available for assignment
from Panel Programming. When the key is pressed, audio from the required crosspoint is
routed to the panel with the key.
This allows panel C to monitor audio between ports A and B when Route Monitoring
between A and B is enabled.
7.11.7 Mute relay
This function enables a specific interface label to activate the source panel’s mute relay
when the talk key for that interface is activated. The mute relay is a general purpose relay
whose contacts are connected to the Miscellaneous DB-15M connector on the panel’s rear
panel. It is commonly used to mute a control room monitor speaker, but it can also be put
to other uses, such as turning on a light or unlocking a door.
