CHAPTER 3
Basic Intercom Operation
Keys and Displays
• Keys that are assigned for talk or talk+listen are indicated
using UPPER CASE letters in the alphanumeric displays
above the keys.
• Keys that are assigned for listen-only are indicated using
lower case letters.
• For momentary activation of a key press and hold the key.
Then, release it when finished.
• For latching operation, tap the key; it will turn ON and
remain ON. Tap the key again to turn it OFF when finished.
NOTE: For lever keys only: You can independently activate
talk and listen by tapping up or down.
Talk and Listen Indicators
The talk and/or listen indicators turn green when a key is activated, depending on the key’s assignment. For example, if the key
is assigned for talk, but not for listen, only the talk indicator will turn green when the key is pressed; if the key is assigned for
talk + auto-listen, both indicators will turn green when the key is activated. If there is no key assignment, they will not activate.
The talk indicator also provides some other indications, as follows:
Continuous red “in use” indication: an “in-use” indication is provided for IFB and ISO keys. An “in-use” indication is also
provided for keys that are assigned to destinations in remote intercom systems (when your intercom system is equipped with
optional trunking). If another keypanel is currently talking to any of these destinations, and you have a key assigned to the
same destination, the talk indicator in that key will light red to indicate “in-use”. If you activate the key and it turns continuous
green, this indicated that you and the other keypanel operator are both talking to the destination. If the indicator flashes green
when a key is activated for an IFB or a remote destination, this indicates that the other keypanel has a higher priority and you
cannot talk to that destination at the current time.
Red flashing “incoming call” indication: If the talk indicator in a key starts to flash red, this indicates that the destination
assigned to that key is calling you. Activate the key as described above to talk back.
