Intercom Key Operation
Basic Intercom Key Operation
The upper button of an intercom key is on continuously (if assigned). The lower button activates the
talk (if assigned). If there is no talk assignment for an intercom key, the talk button will not activate. If
there is no listen assignment, the listen button will not activate.
For momentary activation of a key, press and hold the key. Then, release it when finished.
For latching operation (if enabled), tap the button; it will turn on and remain on. Tap the button again to
turn it off when finished.
Note : Latching may be turned off for the entire keypanel by setting DIP switch 1 on the keypanel to
the “closed” position. Latching may be disabled for individual keys on a keypanel using AZedit or the
latching menu (Menu>KeyOption>Latching). Click the KP button in the AZedit toolbar to open the
Keypanels / Ports setup screen. Select the intercom port where the keypanel is connected. Place a
check mark in the check box marked “D” for any keys where you want to disable latching. Be sure to
send your changes to the intercom system.
Operation of Intercom Keys with Auto Functions
Note : Assignment of keys with auto functions is described in the programming sections that follow.
Descriptions of the auto functions are also contained in the Glossary.
Operation of keys with auto functions is as follows:
Talk + auto follow
Talk and listen can be activated separately. The listen assignment listens to whatever is assigned to
the talk key.
Talk + auto listen
Both talk and listen will activate when talk is activated.
Talk + auto mute
Listen will turn off when talk is activated.
Talk + auto reciprocal
Listen will always be on, and talk may be turned on or off.
Talk + auto table
If an IFB talk key has an auto-table listen assignment, talk and listen can be independently activated.
The listen key listens to whatever is defined as the IFB Listen Source for the IFB that is assigned to
the talk key. For an assignment other than IFB, auto-table acts like auto-follow.
Note : A full explanation of the auto-table feature is beyond the scope of this manual. For further
information, search for IFB in AZedit help, then read the topics IFB Auto-Table Description and IFB
Setup Procedures.
All Call Key
Activating the key will also activate all keys to the left of it (up to, but not including another all call key).
Talk + DIM
If a point-to-point key has the DIM function as a level 2 talk assignment, activating the key will cause
the crosspoint levels to diminish for any other intercom ports that are currently listening to the same
destination and that are in the same DIM table.
Note : A full explanation of DIM tables is beyond the scope of this manual. For further information,
search for “dim table” in AZedit help.
