General Information
The Two Functional Modes
As its dual name signifies, this unit can perform two
distinct functions: clock and communications. Its master-
clock functions include keeping time, controlling different
events (e.g., ringing bells, turning lights and equipment on
and off), and correcting secondary clocks. Its communica-
tions functions include showing call-ins from associated
room stations; using its dial pad for calling rooms, paging,
and distributing a program source; checking the room-sta-
tion wiring for
faults;
and monitoring room stations.
schedule. In the “Comm” Run Mode, only the “Comm” LED
will be lit; the “Station” window will be dark unless it is
displaying the number of a room that is calling in or is in
communication with the system operator.
Variations In Equipment
-i
Which operations a given 2524 will run depends in part
upon what other equipment is in the system. The most
obvious example is the “Comm” mode, which requires such
items as a Director intercom control panel, speaker relay
panels, and room speakers. As you go through this manual,
you may find it helpful to place a check mark next to the
operations that apply to your system, or to cross out those
that do not apply.
As soon as it detects a call-in or its numerical keys are
used to dial a room, the 2524 automatically switches from
the Clock Run Mode to the “Comm” Run Mode. When all
such
communications have ended, the 2524 automatically
switches back to the Clock Run Mode.
Exception: If you manually switch from the “Comm” to
the Clock Run Mode while a call-in is displayed, the 2524
will not return to the “Comm” Run Mode until you switch
it back manually. The 2524 will continue to signal waiting
call-ins with a “beep,” but you will not be able to answer
them from the 2524 until you switch it back to the “Comm”
Run Mode.
Variations in Programming
The other major factor that determines which operations
the 2524 will run is the programming. For example, the
2524 will not even enter the “Comm” mode unless that has
been enabled. See the programming manual, KI-1629, for
complete information.
Because
the 2524 displays little information in the
“Comm” Mode and automatically switches to it for call-ins,
you should not normally switch modes manually. However,
you will have to switch to the “Comm” mode before you
can begin certain “Comm” functions (and to the clock mode
for its functions).
Changing Run Modes
When the 2524 is in the Clock Run Mode, the “Clock”
LED remains lit and its displays show the time of day, any
event-zone activities, the day of the week, and the current
