General Information
The Two Functional Modes
As
its name signifies, the
ChronoCom
unit an perform
two distinct functions:
chronometric
(clock) and commu-
nications. Its master-clock functions Include keeping
time, controlling
different
events (e.g.,
ringing bells, turn-
ing lights and equipment on and off), and correcting
secondary clocks. Its
communiations
functions
Include
showing all-ins from
associated room
stations;
using its
dial pad for calling rooms, paging, and distributing a
program source; checking the
room-station
wiring for
faults;
and monitoring room stations.
event-zone activities, the day of the week, and the current
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 opentor.
Variations in
Equipment
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 all-in or its
numerical
keys are
used to dial a mom, the 2524
automatically
switches from
the Clock Run Mode to the “Comm” Run
Mode. When all
suchcommunications 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 all-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
all-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
opera-
tions the 2524 will run is the programming. For ample,
the 2524 will not even enter the “Comm” mode unless
that has been enabled. See the programming manual,
KI-1629, for complete information.
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
Because the
2524 displays little Information
in
the
“Comm”
Mode
and
automatically
switches to it for all-ins.
you should not normally switch modes manually. How-
ever, you will have to switch to the “Comm” mode before
you an
begin
certain “Comm” functions
(and
to
the clock
mode for its functions).
