Call Signals
To activate a call signal:
1. Push and hold (for at least 1 sec.) the Listen Level selector until the
panel indicates it is in Call Signal mode.
2. Push down the talk selector with the desired label.
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 sec.).
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 selector for at least 1 sec. to activate
the call-signal mode.
2. While holding the Listen Level selector, press the talk selector of the
desired telephone’s label.
3. Release the Listen Level selector.
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.
