1. Push and hold (for at least 1 second) the “Listen Level” button until
the panel indicates it is in “Call Signal” mode.
The call signal will be sent each time the selector with that label
assignment is pushed down and will remain so until the call-signal
mode times out (about 5 seconds).
Call signals can be issued to any talk label assigned to a panel’s
talk/listen selectors. If more than one label is assigned to a selector, all
labels will receive the signal. If a label is a fixed group, the entire group
will receive the call signal. If the label is a party line, then every panel
listening on the party line will receive the call signal.
Remote Telephone Line Release
This function is available only if specifically enabled in the
configuration program. To hang up a telephone interface left off the
hook:
1. Push and hold the “Listen Level” button for at least 1 second to
activate the call-signal mode.
2. While holding the “Listen Level” button, press the talk selector of the
desired telephone’s label.
3. Release the “Listen Level” button.
Note: In addition to hanging up the telephone interface, this will
deactivate any talk/listen selector set to the interface from
anywhere in the system.
Listen Labels Button
The “Listen Labels” button displays listen labels on the front panel and
any display expansion panel (XPL-12 or XPL-22) connected to the
panel. Momentarily pressing and quickly releasing the button will
cause all panels to display the listen labels assigned to the selectors. If
the listen and talk labels are the same, then there will be no change.
When this function is active the green LED next to the “Listen Labels”
button will be lit. To exit this mode momentarily press and release the
“Listen Labels” button again. The panel displays will return to their
normal state and the green LED next to the “Listen Labels “ button will
be extinguished.
Panel Upgrade Facility
If a panel firmware upgrade is downloaded to the matrix by ECS with
the “Panel Prompt” option set the panel user will be asked whether the
firmware upgrade should be applied. The panel will display the
message “UPGRD TO VER nnnnn YES NO” on the display, with each
word as a label (nnnnn is the version number). The panel keys will
flash indicating an upgrade is available. This prompt will be displayed
when the upgrade is available if the panel is online, or when the panel
goes online if it is offline when the upgrade is downloaded to the
matrix.
