INTERCOM KEY OPERATION
Momentary vs. Latching Operation
For momentary key activation, press and hold an intercom key. For latching operation, tap the key
to turn it on, and tap it again to turn it off.
NOTES
• If the LED next to a key does not turn on when the key it activated, this means the key is not
currently assigned.
• The electronic latching feature (DIP switch 5) must be enabled in order to use latching. See
Section 2 for details.
Intercom Key Operation for Different Types of Key Assignments
Basic Talk and/or Listen Key Operation: The down position activates talk (if assigned). The up
position activates listen (if assigned). Talk and listen may be latched on or off independently by
tapping up or down.
NOTE
The following paragraphs describe special types of key assignments called special functions.
These types of key assignments can only be set up using the ADAMedit or ZEUSedit software,
and they are described in detail in the software help file. To find out if a key has a special function
assignment, you can display the key's assignment as described under “Displaying Key
Assignments”. If a special function is assigned to a listen key, you will see AF, or AL, etc. when
you display the key assignment.
Talk+Auto-follow (AF) Listen Key Assignment: This key assignment works the same as the
basic talk/listen key assignment: The down position activates talk, and the up position activates
listen. Talk and listen may be turned on or off independently by pressing up or down.
Talk+Auto-listen (AL) Listen Key Assignment: The down position activates both talk and
listen. However, only the talk LED will turn on. If talk is on, you cannot turn off listen. If talk is
off, you can turn listen on independently by pressing up.
Talk+Auto-mute (AM) Listen Key Assignment: The down position activates talk. And, if listen
is on, it automatically turns off until talk is released. When talk is off, listen may be turned on
independently by pressing up.
Talk+Auto-reciprocal (AR) Listen Key Assignment: The down position activates talk. Listen
is always on and continuously monitors whatever is assigned to the talk position.
All Call (AC) Talk Key Assignment: When a talk key is assigned as an All Call key, it operates
only as a switch to turn on or off all talk keys to the left of the All Call key. These other talk keys
will then activate according to the way they have been assigned. Note that will also affect any
listen keys that have been assigned with special functions. For example, an auto listen key will
also activate if its corresponding talk key has been activated by an All Call key.
