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).
Press Clock/Comm to toggle the operation modes.
* The ”Clock” or “Comm” LED will light to show which
mode the 2524 is currently in, and the display will
change, as described in the introduction to this
subsection.

This can be done while the 2524 is in either run mode.
Step 1. Type the station’s threedigit Architectural (di-
aling) Number.
m If the 2524 was in the Clock Run Mode, it will

number you dialed will flash in the “Station” win-
dow.
Step 2. Push Page.
np The 2524 will show “Page” in the “Station” window,
light the LED of the selected zone (or all of the
paging zones’ LEDs for an A&Page). connect the
intercom control panel to all the appropriate room
stations, then “beep” for you to start talking.
Step 3. When you have finished paging, press Reser to
end the page.
y The 2524 will switch back to the’clock Run Mode if
no call-ins are present.
Paging from a Remote Phone
This can only do an A&Page. Simply press the associ-

the page. hang up.
Distribute a Program
You can send an audio program to any stations d&red
when the system is idle (i.e., no paging, intercom commu-

Pressing the right cursor will bring up the next
station (according to the wiring) that is receiving the
program; when all have appeared on the display, the
“Station” window will show “000” and the 2524 will

in the “Station” window.
Step 3. To turn the programming on or off for an
individual station, press Program while its number is
displayed in the “Station” window.
* The “PM” LED will light when programming has
been selected, and go off when the programming has
been canceled.
Step 4. To end the program distribution, cancel it for

Monitoring
This function enables you to continuously listen to a
selected group of stations in order to detect any distur-
bance that might require a response. The 2524 momen-
tarily connects the intercom control panel to each station
in succession, and continues cycling through the stations
until you end this function.
Note that the 2524 programming determines which
stations are to be monitored, how long the 2524 will
pause at each one, and whether this function can be used.
Step 1. To surt monitoring the programmed stations,
press the right-cursor key (-+).
m The 2524 will sequentially connect the selected sta-
tions to the intercom panel. As each station is mon-
itored, its Architectural Number will be displayed in
the “StationW window.
