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
Press Clock/Comm to toggle the operation modes.

(however, it will not run any events that were
skipped).
Manual Zone Activation
This function can be used to activate any “Zone-Outputs”
desired (except those used for correcting clocks). Depend-
ing upon what is wired to the selected outputs, the result
could be sending time tones or activating lights and equip-
ment. This manual activation can be used to send a special
signal or to test the system.

Test All Speakers
.
This function enables one person to check, unassisted,
whether all the room speakers are operating. It activates all
the zones (except those used for clock corrections) for a
limited number of seconds (determined by the Clock Mode
5 programming) and automatically repeats the test every
minute.
Step 1. Push Manual, then Funct.

when they are
used for “Comm” functions. A special stick-on label, sup-
plied with the clock, lists both sets of names. These names
are also listed in the smaller table at the back of this manual.
Answering Call-ins
Step 1. The person at the room station places a call-in
by pressing the call-in push button there. Some rooms may
have two push buttons: one for normal call-ins, and one
for priority (emergency) call-ins.
)aThe 2524 will automatically switch to the “Comm” Run
Mode and flash a “C” (regular Call-in) or a “P” (Priority
call-in) plus the station’s number in the “Station”
window. It will “beep” every 10 seconds for normal
call-ins or every two seconds for priority call-ins, It
will queue all priority call-ins ahead of normal call-ins;
within each group, it will queue the call-ins in the
order that they were placed. The “Sched” window will
show the number of call-ins waiting (from l-9); if
there are more than nine, it will show “E” (“Exceeds
nine”).
Step 2. Press the Answer key when the call-in is
displayed in the “Station” window.
NThe 2524 will connect the station to the intercom
control panel.
Step 3. Press Reset to end the communications.
v If more call-ins are present, the 2524 will display the
next one in the queue; otherwise, it will switch back
to the Clock Run Mode.
Answering from a Remote Handset
Step 1. Lift the handset from the hook switch.
‘BThe 2524 will connect the handset to the station.
Step 2. To end the call, hang up.
x The 2524 will disconnect the station. If there is a call-in
waiting, the 2524 will signal this. Otherwise, the 2524
will return to the Clock Run Mode.
Cancel All Call-ins
This would usually be done only if there are spurious
call-ins or if a technician wants to clear the system before
testing it.

individual station, press Program while its number is
displayed in the “Station” window.
v 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
each station currently receiving the program. (Use the right
cursor arrow to run through all the stations currently
receiving the program, and use the Program key to turn
off the programming for that station.)
Step 5. To exit this mode (whether or not the program
is running), press Reset.
‘BThe 2524 will return to the Clock Run Mode.
Monitoring
This function enables you to continuously listen to a
selected group of stations in order to detect any disturbance
that might require a response. The 2524 momentarily
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 start monitoring the programmed stations,
press the right-cursor key (+).
x The 2524 will sequentially connect the selected sta-
tions to the intercom panel. As each station is moni-
tored, its Architectural Number will be displayed in
the ‘Station” window.
Note: If a call-in comes in while the 2524 is monitoring,
the unit will “beep” and display a “C” or a “P” in the “Sched”
window. To answer the call-in, first exit the monitoring
function.
Step 2. To stop scanning and remain connected to one
of the stations, press Enter when its number is displayed
in the “Station” window.
)) The intercom panel will be in communication with
the selected station. To resume scanning, exit (Step 3),
then begin afresh (Step 1).
Step 3. To stop monitoring, press Reset.
)) The 2524 will return to the Clock Run Mode (or the
“Comm” Run Mode, if there is a call-in).
Manual Supervision
The supervision function checks the speaker wiring of
selected stations for defects (a short or a break in the
wiring). The 2524 can be set to automatically run this check
every hour. You can also run this check manually at any
time, The 2524 programming selects the rooms to be
checked and enables this function.
