General Information
Description
The Rauland 2524 is a multi-function Master Clock and
Communications Control Center. As a master clock, it will
synchronize virtually any kind of secondary clock and
control up to 350 “events” (such as sending tone signals
or turning lights and equipment on and off). As an
intercom controller, it adds control of room-switching
functions and display functions to Director III intercom-
control panels.
Manuals
This manual tells how to program the 2524 for both
clock and intercom functions. The first section gives the
basic programming procedures. The “Clock Modes A-F”
section explains the programming for the general settings
needed by the unit, whether it is used only as a master
clock or also as a control unit for communications. The
last two sections deal with the clock and intercom func-
tions, respectively.
Generally, the Clock Modes A-F, especiallyClockMode
A, should be done before the numerical modes. Refer also
to KI-1628, 2524 Installation, and KI-1630, 2524 Opera-
tion.
Following the text are four tables that list all of the
programming functions. Also attached are awork sheet for
devising a special clock-correction code and charts for
planning the system programming.
Power-up
When the 2524 is turned on, its displays normally
appear as follows: the “Mode” window reads “0” (Run
Mode), the “Time” window shows the current time, the
“Sched” (“Schedule”) window shows a flashing “P” (to
indicate that the power was off), and the “Clock” LED lights
(to show the unit is set for clock operation). Push any key
to stop the flashing “P.”
The “Sched”window will show the number of the
schedulecurrently in use.
Note; If the battery was “disabled” (see IL0341 in
KI-1628), the “Time” display may be random. In this case,
set the date and time (Clock Modes 1 and 2).

Programming Summary
This section gives the procedures for accessing, chang- Mode 4. The remaining modes may be programmed in any
ing, and entering programming information. order.
Access to Programming
.
After this summary, there is a section on planning. Then
the three groups of programming modes are explained.
The alphabetical modes (A-F) are explained first, because
this group affects both clock and intercom operation;
moreover, these settings are usually entered during setup
and left that way, except for the annual holiday and
Daylight Savings Time changes. The other clock and the
intercom modes follow in that order,
To begin programming, the clock must be in the Clock
Run Mode (“0”).
Step 1. Enter the Security Code (Funct 2524 that is,
press in succession the Funct, 2, 5, 2, and 4 keys):
Disabling Programming
Jumper J2 on the main circuit board of the 2524 can
prevent any programming changes from being effected.
Although the displays would still change as a user entered
different values, these changes would not be recorded in
the EEPROM and so the old settings would remain in effect.
The only changes that could be effected from the front
panel would be the time and date, and not even these
could be changed from a computer running the T2524
Diagnostic Program and connected to the 2524’s serial
port.
The “0” in the “Mode”window willflash, meaning
thatyoucanselect aprogrammingmode.Ifyoupause
more thanfive secondsbetweenkeystrokesor enter
invalid keystrokes, the clock will display “‘Err0,”
‘beep,”and, after a moment,revertto theClockRun
Mode.
Step 2. To select the Clock Modes, skip to Step 3. To
select the “Comm” modes, push the white Clock/Comm
button,
The "Comm”LEDwill light steadily,a “1”willflash in
the “Mode”window, and a "P” will appear in the
“Sched”window.
As viewed from the front of the 2524, J2 is near the
right rear comer of the circuit board, near the four-pin
header of the serial port. J2 has three pins and a sleeve
jumper that slides over two pins. To disable the program-
ming, place the sleeve jumper over the middle and rear
pins (the “DIS” setting). To enable programming, place the
sleeve jumper over the middle and front pins (the “EN”
setting).
Note: Once you select intercom programming, you can
only select those “Comm” modes. To select the clock
modes, you have to first exit to the Clock Run Mode, then
begin again with Step 1.
Step 3. To select a numbered mode (l-9, type in its
number; to select a letter mode, press Funct while you
type the corresponding number (“1” for “A,” “2” for "B,”
etc.).
Caution Accessing this jumper require removing the
top cover of the 2524, which, in turn, entails removing the
power connections on the rightmost rear screw terminals
(as viewed from the rear). Be sure to turn off the AC power
going to the unit before beginning. Follow the directions
in KI-1660 when reconnecting the power.
The numberor letteryou selectedwill showsteadyin
the “Mode” window. You can now either enter a
different modeor commence programming.
General Methods
Sequence
Important: Before entering clock events (Clock Mode
3) or editing them (Clock Mode 4), you should enter any
clock-correction codes (Mode A), because each code takes
up two outputs that are not, consequently, available for
events. The 2524 will not allow you to enter an event for
a zone that is taken up by a clock code. Should you enter
events for zones that you subsequently take up with a
clock code, the 2524 will not erase them. However, it will
not activate events in clock-code zones, and these zones’
LEDs will not light when you review the events in Clock
Flashing, whether in a window or an entire group of
LEDs, marks the spot (field) in the programming that will
be affected by your entries. We refer to this flashing area
as the “flashing cursor.”
Step 1. When you are in the desired mode, use the
cursor keys (t and -+) to move to the desired window or
LED group.
Step 2. Use the digit keys to enter the desired program-
ming. Keys l-8 toggle the individual “Zones” and “Days”
LEDs on and off.
Step 3. Use the orange Clear key to restore a field’s
previous setting (except in Mode B, where it is used to

enter the entire series of numbers). When you are sure all
the entries for the mode (or individual event) are correct,
press the orange Enter key.
a Thenewprogramming will bestored in the clock’s
memory,and the “Time” window and any involved
LEDS will light steady, to showyour final entries. If
you enter invalid data, such as “13"for the month,
the2524 will ‘beep”andflash theleft-mostfield that
bad an error (for timesand dates,the2524 typically
revertsto thelast valid entry). Correctthatfield and
press Enter, which will causethe2524 to recordthis
change and check for any othererrors.If itfinds one,
it willflash thatfield.
Note: In Modes 1 and 2, the 2524 will automatically
advance to the next mode after you press Enter.
Exiting
To quit programming, return the cursor to the “Mode”
window and type a “0” (Clock Run Mode). Alternatively,
do nothing for one minute. In either case, the 2524 will
return to the Clock Run Mode.
Planning
Information Needed
Because of the interrelation between the wiring and the
programming, a good deal of programming-related plan-
ning was required for the installation. You need the
following information from that planning:
4 What is connected to each “Zone/Output” terminal
(secondary clocks, equipment, etc.).
4 What, if any, secondary clock codes are needed; if
two are used, which is needed for Outputs 5 and 6,
and which for Outputs 7 and 8.
4 How many relay panels are connected (0-20).
4 Whether there is an audio program source that can
be used for clock events (“Music”).
4 Whether there is a tone generator for clock tones.
From the customer, you need to find out:
4 The desired schedules for clock events, including
holidays.
4 The desired zones for clock events and intercom
paging.
4 The dates of the holidays and other special days for
which a special schedule is desired. (You also need
to know the dates for the changes to and from
Daylight Savings Time.)
4 The calling (“Architectural”) number that should be
programmed for each room station (typically the
same as the room number).
4 Which rooms should be included in the monitoring
function. (When this function is activated by the
operator, it continuously cycles through the selected
stations, so that the operator can listen for any
unusual sound that signals a need for action.)
Most of this information can simply be entered in one
or two steps and, accordingly, will be explained in the
appropriate “Modes” section of this manual. The events
and the paging zones require more planning.
Planning Charts
Completing the charts attached to the end of this manual
is an important part of planning. This will help you
organize the programming, make it easier to enter the data,
give the user helpful information, and simplify later pro-
gramming changes. When you are finished, provide copies
to the users and keep a set for your own files.
Zones Chart
When the 2524 is wired and used like a conventional
master clock, you can easily figure out how its zones can
be used. Any output connected to secondary clocks or to
equipment can serve only them.
However, wiring the 2524 to speakers via relay panels
introduces a second type of zone, which is determined by
the software in “Comm” Mode 2. Although these two types
of zones work independently in some respects, they are
closely interrelated:
l These software zones are used for both events and
paging; thus, a page sent to Zone 4 will include
the same speakers as a clock-tone event.
l The eight zones are tied in with the 2524’s
“Zone/Output” terminals. For example, if Outputs
7 and 8 are used for a clock-correction code, you
cannot use Zones 7 and 8 for events (e.g., for
sending clock tones via speakers).
l To have clock tones via speakers, the correspond-
ing output terminals must be wired to the tone
generator, in order to activate the tone signals.
This eliminates the use of clock events via speak-
ers in any zone whose corresponding output
terminal is used for correcting clocks or control-
ling equipment.
l It is possible to have paging zones when the
corresponding outputs are used for clock-correc-
tion codes. However, since the output terminals
Page 4 6/94

2524 Master Clock and Intercom Controller Programming
are tied up, they cannot channel tones or music
to the speaker zones.
- All of these factors are summarized in the following
table. Note that only one of the listed combinations can
be active in a zone at a time. The first four zones have only
two choices because clock-correction codes can only use
Outputs 5-8.

The “Duration” (Clock Mode 5) tells how long an event
will continue: 1-59 seconds for tones, or “00” for latched
events (an event with “00” duration holds the affected
zone’s relay closed until another event, which does not
include that zone, is executed). The “Description” is for
the programmer and user. For example, a zone could be
described as an area (“West Wing”), a classification (labo-
ratory classes), atime (evenings, week-ends), or afunction
(outside lights).
Stations Chart
This is needed only when relay panels are controlled
by the 2524. Although the chart primarily deals with
intercom functions, the “Paging Zones” entry directly
affects clock tones sent to the speakers.
Physical Number: This refers to specific terminals on
the relay switching panels. The first terminal on the first
panel is “001,” the first terminal on the second panel is
"026," and so on. The system uses these numbers to keep
track of each station (e.g., to determine which station is
calling in, or to determine which relay to close to connect
the operator with a station). The only way to change a
station’s Physical Number is to wire it to different terminals.
Architectural Number: This is the number the user
will enter on the 2524’s keypad in order to call the room.
The 2524 locks up the corresponding Physical Number to
carry out the desired communications function.
Users typically want the room number for calling, but
any three-digit number can be used. Make sure that you
do not assign the same number to more than one station.
Paging Zones: Each room can be assigned no zones
or from one to eight zones in any combination. Assigning
a zone to a station means that the latter will receive both
paging and clock events for that zone.
Monitor: Giving a station this feature means that it will
be included when the 2524’s monitoring function is en-
abled (see also “Comm” Modes 3 and 4). When activated
in the “Comm” Run Mode, the monitoring function mo-
mentarily connects the control panel to each selected
station in succession, so that the user can listen for
disturbances or unusual sounds. The length of time that
the 2524 remains connected to each station is determined
by “Comm” Mode 4.
Note: This function is not available for CCOM systems
using CTLl.
Supervision: This setting determines whether or not a
station will be included when the 2524’s supervisory
function is activated. This function scans the selected
stations for wiring faults. When activated in “Comm” Mode
3, the function automatically runs every hour; it can also
be manually activated at any time.
Program: Each room can be set up to automatically
receive music or other audio programs whenever they are
run. This setting is made in the intercom operating mode,
and so is described in the 2524 operation manual, KI-1630
(see the subsection “Distribute a Program” under “‘Comm’
Mode”).
Note: Clock tones, pages, and calls to an individual room
will override the program function to all rooms. As soon
as the clock tone or intercom activity ends, the program-
distribution will resume.
The Events Chart
This chart contains the most columns and will typically
have the largest number of entries. In order to fill it out,
you first have to fill out the charts explained above.
An “event” is simply the automatic closing of a “Zone”
output terminal and the pulling in of relays on optional
speaker relay panels.
6/94
Page 5

2524 Master Clock and Intercom Controller Programming
The circuit closure on an output, in turn, is used to
control external devices connected to the clock. The
output may activate for a programmed time between one
and 59 seconds (to ring bells, for instance), or it may be
left on until it is turned off again by another event at a
different time (to control lights or heating equipment, for
instance).
this is the one selected in Clock Mode 6 and displayed in
the “Sched” window. However, the regular schedule will
be overridden by a holiday schedule (Clock Mode C).
The pulling in of panel relays enables clock tones or an
audio program to be sent to room speakers.
Zones: To decide which zones to place each room in,
you must understand how zones work (see the “Zones
Chart” subsection) and know the customer’s needs (which
rooms are to receive pages together, which will receive
clock tones together, etc.).
Entering an event requires five pieces of information:
the time and the days when the event will take place,
which “Zone” outputs will be activated, which schedule is
involved, and, if music or other audio programming is
desired, how long it should play.
Note that a zone must also be selected in Clock Mode
6. An event will be executed only in the zones that have
been entered in the event andselected; however, such an
event could still turn off an ongoing latched event in an
active zone (see the “Important” note further on in this
subsection).
“Event No.“: This column is for your reference only-to
keep track of the number of events, etc.; it is not pro-
grammed into the clock.
Time: If you are using the 12-hour display format, be
sure to indicate “AM” and “PM”; if you are using the
24-hour format, leave the “AM” and “PM” columns blank
but use “13"-“23” for the “PM” hours and “00” for the
Midnight hour. Use this chart for your own and the user’s
convenience: should you subsequently change modes, the
clock will automatically adjust the times for the events.
Thus, if you are more familiar with the 12-hour mode, you
can enter everything that way and then change the clock
to the 24-hour mode.
The distinctive feature of event zones is that they use
the 2524’s “Zone” output terminals, whether or not relay
panels are involved. To send tones to speakers, the system
must include atone generator. Because the “Zone” outputs
are needed for clock corrections (except for digital clocks
wired to the 2524’s “DIG” output), the number of event
zones available for use is reduced by two for every clock
code that is programmed into Clock Mode A.
Latching events effectively monopolize a zone. You
must give their zones a duration of “00” in Clock Mode 5.
Important: Latched events will end upon the execution
of any subsequent event that does not include their zones.
This could be a regular event or a special “no zones” one
whose sole purpose is to end latched events.
You may schedule multiple events for the same time.
For example, you may want different types of events in
different zones but starting at the same hour of the day, or
you may want to vary the types or sequence of events on
different days of the week.
Exception: When there are two or more events that will
execute at the same time, only one of them needs to
include the zone for the latched event.
Days of the Week: You may program each event to
occur on one to seven days of the week, in any combina-
tion of days.
Music: This should only be selected for speaker zones.
Besides having relay switching panels, the system should
also be equipped with the necessary program-distribution
equipment (e.g., a Director master control panel, a tuner
and cassette player, and an appropriate Rau1and power
amplifier).
Schedule: Enter a number from “1” to “8” and add a You can select a duration of one to 15 minutes. After

Clock Modes A-F
As was explained earlier, these general settings, espe-
cially Mode A, should be entered first. Before beginning
here, you should fill out the charts, as explained in the
“Planning” section.
Mode A (Preprogrammed Clock Codes)
Outputs 5-8 can be used individually to control clock
events or in pairs to correct secondary clocks. Each type
of secondary clock has its own sequence of correction
signals (frequency, duration, etc.); see KI-1628, the 2524
installation manual, for an extensive listing of secondary
clocks and the correction codes they require. Two of these
codes can be used simultaneously in the 2524. Digital
secondary clocks can be controlled by the 2524’s Dig
output; this arrangement does not use up either a Mode A
code or any event-zone outputs,
Note: The 2524’s standard codes should correct all of
the widely distributed secondary clocks and most of the
others. You should be able to accommodate virtually any
clock by entering a custom code for it in Mode B, below.
Step 1. After entering the programming function, press
Funct while you type 1 to select Mode A.
--
0 Thelefthalf ofthe “Time”window will dsiplaythefirst
correction code,and the right half will display the

up correction is disabled, or "E” ifitis enabled(see
Step3).
Step 2. Use the right cursor key (+) to select the “Time”
window.
If only onecorrection code is needed, enter its two-digit
code (e.g., “07”) in the left “Time” window, and enter “00”
in the right “Time” window. In this case, Out 7and Out8
will be used for correcting the clocks.
If a secondcorrection codeis needed, enter it (for Out
5and Out 6) in the right “Time” window.
Ifyou donotwant any code, press Clear to change both
entries to “00.”
You can also use Clear if you make a mistake and want to
re-enter the codes.
- As soonasyou entera digit, it will replacethecorre-
spondingdigit in the “Time” window, and the "Zone”
LEDswill turn off
Step 3. Press + to move to the “Sched” window. Push
Funct to toggle between the “E” (enabled) and “d” (dis-
abled) setting for immediate time correction. When this
function is enabled, the 2524 will send corrections to the
secondary clocks immediately after the restoration of
power after a power failure; when the function is disabled,
the 2524 will only send corrections at the regular times
(hourly and 12-hour).
Step 4. Press Enter to record your changes.
The “Time”and “Scbed”windows will showsteady,
and the “Zone”LEDswill light toshowwhich outputs
are now available. However, if the 2524finds an
invalid codeentry, it will “beep”and keepthecursor
on the “Time”window.
Mode B (Custom Clock Code)
This mode is used to program a correction routine for
a secondary clock that does not match any of the 2524’s
standard codes. You can enter up to two sets of seven
integers. The first set consists of Integers “01” through “07,”
and the second set consists of Integers “08” through “14.”
Creating a Custom Code
Find out the precise correction requirements of your
special secondary clock. This includes such items as the
on and off times for correcting the time, whether there is
more than one clock motor involved, and the output or
outputs on the 2524 to which the clock is wired. Use the
“Custom Code Work Sheet” at the back of this manual to
establish the 2524 programming for the clock. After enter-
ing this programming into the 2524, keep this work sheet
with the other installation documents for future reference.
Entering the Custom Code
Step 1. After entering the clock programming modes,
select Mode B by holding in Funct while you press 2.
A “b” will appearin the ‘Mode”window, and theleft
“Time”windowwill display “01,“wbicb indicatesthat
thenumberin theright window istbefirst integer for
thecustomcode.
Step 2. Push + to move the flashing cursor into the
right “Time” window.
Tbe twodigits in that window willflash.
Step 3. Type in the first two-digit number from your
work sheet, then push Enter.

The left “Time” window will increment to the next
number,and the right window willfinish thecurrent
entryfor that integer.
Note: For integers that need to be designated asminutes
or seconds (bytes 4, 6, 11, and 13, push Funct to toggle
between minutes and seconds (the “PM” LED lights for
“minutes”). When the setting is satisfactory, press Enter
Step 4. When you have finished with this mode, push
Clear to enter your code into the EEPROM.
All the custom-codesettingswill beentered, and the
“Time”windows will showthefirst integer.
Step 5. Go to Mode A and enter “21” as one of the
correction codes. Be sure to select it as the first or second
code in accordance with your work sheet.
Mode C (Holidays and Time Changes)
This mode is used to enter the dates for the holidays
and Daylight Savings time changes.
Step 1. After entering the clock programming modes or
finishing in another mode, select this mode by holding in
Funct while you press 3.
A "C”will appearin the “Mode”window.
Step 2. Press + to move the “flashing cursor” to the
“Time” windows.
The “Time”windows willflash.
Step 3. To select a day for a special schedule or an
automatic time-change, type two digits for the month and
two more for the date (MMDD). Press + to move the
cursor to the “Sched” window.
The “Time”windows will go steadyand the “Sched”
window willflash.
Step 4. Make one of the following entries:
Todisableall eventson that day: Type “0.”
To selecta special schedulefor that day: Type in the
schedule’s number (1 through 8). Whether or not the
schedule is selected in Mode 6, it will automatically run
on this date.
Torepeat a holidayscheduleonconsecutive days: After you
enter a schedule number, as explained in the preceding
paragraph, the Schedule window will go steady and the
“Music” LED will flash. If you want the holiday schedule
you just entered to run for more than one day, type “1.”
The left “Time” display will show “du” (“duration”).
Type in an integer (from 1 to 15) to specify how many
consecutive days you want this holiday schedule to run.
This option is useful Forvacation periods.
Toadvancethetime onehour at 2 a.m.: Press Funct and
1 to enter “A” (“Advance”) in the “Sched” window.
Toturn backthetimeonehour at 2 a.m.: Press Funct and
6 to enter “F” (“Fall” or “fall back”) in the “Sched”
window.
Step 5. When you are satisfied with your entries, press
Enter.
The 2524 will check your entry for a valid date; if
it finds an error, it will flash your entry in the
“Time” windows. If you entered a “duration” value
(to repeat a holiday schedule), the program will
check it for validity, too. If it finds an error, it will
“beep” to indicate an error, continue displaying
“du” in the left “Time” window, and flash the right
“Time” window. If you did not enter a duration
value or if the program does not find any errors, it
will store this holiday event and flash the “Time”
windows again, signaling that it is ready for an-
other entry.
Mode D (Edit Holiday events)
This mode isused to review, edit, and delete the holiday
and time-change events entered in Mode C.
Step 1. After entering the clock programming modes,
select Mode D by simultaneously holding in Funct while

Step 4. When you are finished programming in this
mode, move the flashing cursor to the “Mode” window
and select another programming mode or enter “0” to
return the 2524 to the Clock Run Mode.
Mode E (Relay Panels, Comm
Activation)
.
,
This mode has three settings. The first tells the 2524
how many “SC” relay panels (TC4110, TC4130, or TC4131)
are connected to it. The second tells the 2524 whether or
not it should activate its communication functions. Unless
this operating mode is activated here, the 2524 will not
receive call-ins, make calls, do paging, or even enter the
“Comm” mode. The third setting determines whether or
not the 2524 will handle call-ins.
--
Important: Be sure to enter the correct number of relay
panels. If, for example, you specified “20” but there were
only two, the 2524 would operate correctly but more
slowly, because it would waste time trying to work with
non-existent relay panels: checking them for call-ins, trying
to pull them in for paging, etc. On the other hand, if you
were to specify fewer relay panels than there actually are,
the 2524 would ignore call-ins from the higher-numbered
panels, and you would not be able to call rooms connected
to them. If no relays are connected to the 2524, leave the
intercom function disabled (the factory setting) to prevent
an operator from entering the “Comm” Mode, which
blanks out the clock information from the front panel.
Step 1. After entering the clock-programming function,
hold in Funct while you press 5.

play theappropriate number, and the “Scbed”win-
dowwill show “H.”
Step 3. To simultaneously delete all events (both regular
and holiday), move the flashing cursor to the “Time”
windows, push and release the Funct key, type “2524,”
then press Enter.
Note: It does not matter which kind of events is currently
displayed, since this procedure will erase both kinds at the
same time.

Mode 5 (Zone Duration)
This mode is used to program the length of time
(duration) that each zone’s relay will close when it is
activated by an event. Two kinds of events are set up here:
regular, short-duration events like sounding a bell tone,
and latched events, which turn on a relay and leave it on
until another event turns it off. Latched events are used for
controlling such things as lights and equipment for heating
and cooling. Note that the duration for music or other
program material is set as part of the event itself in Mode
3.
Note: A holiday entry will execute the events in its
selected schedule even if they have not been selected in

return the 2524 to the Clock Run Mode.
Mode 6 (Activate Zones and
Schedules)
This mode determines which zones and schedules are
active. Unless a zone is “turned on” in this mode, it will
not run even though it is included in a regular event that
the 2524 executes. For example, if a regular event included
Zones 1-4 but only Zone 3 was activated in Mode 6, the
2524 would only carry out this event in Zone 3.
Only one schedule can be active at a time, and only
those regular events that have the currently selected
schedule will be executed.

the 2524, To enter this mode from any programming mode,
type a “0” while the “Mode” window is flashing. Note that
the 2524 will automatically revert to the Clock Run Mode
from any programming mode after one minute of inactivity
(no button is pushed).
.
Communication Modes
Before beginning here, you should have filled out the
programming charts, asexplained in the “Planning” section
of this manual. You should also have performed the clock
programming modes, especially Mode A.
Entering the "Comm" Modes
Step 1. Enter the programming function in the usual
way, by typing in the security code (Funct 2524).
QA “0” willflash in the "Mode”window.
Step 2. Press the Clock/Comm (upper right) key once.
0 The"Comm”LEDwill light and the “Clock”LEDwill
go out, indicating that the 2524 is in the intercom
function. The“Mode” window willflash “1.”
Step 3. Enter the number of the desired “Comm”
programming mode (other than “1”).
Note: Once you have entered the “Comm” function, you
can access only the “Comm” programming functions. To
program clock functions, you must first return to the “Run”
Mode, which will automatically return the 2524 to the
Clock Run Mode.
Mode 1 (Room Numbers)
This mode is used for entering the “Architectural Num-
ber” for each room that can be called. This is the number
that the user “dials” on the 2524’s keypad when calling the
room, and it is the number that appears in the “Time”
windows when the room calls in. We designate this
number “Architectural” because many users find it conven-
ient to assign the room number for this purpose.
Step 5. To change the Architectural number, type in the
new one (any number from “001” to “899 for an active
station, “000” for any unused Physical Number). Push Enter
to store the new Architectural Number.
0 i%e “Sched”window will change to “P" and the
“Station”window will showthene.xt-highestPhysical
Number
The 2524 uses a set of “Physical Numbers” that corre-
spond to the room wiring. In this programming, you assign
an Architectural Number to each Physical Number that has
an intercom speaker. The 2524 then refers to an internal
table of Architectural and Physical Numbers so that it
knows which relay to activate and which number to
display.
Step 6. Repeat Steps 3 through 5 for each number you
want to check or change. When you are finished, use the
left cursor (t) to move back to the “Mode” window, Enter
a different number to program in another “Comm” mode,
or enter “0” to return the 2524 to the Clock Run Mode.

Mode 3 (System Options)
This mode is used to activate optional features of the
unit. Monitoring and supervising have already been ex-
plained, in “Comm” Mode 2.
TC4200 Display
This optional Vacuum Fluorescent Display will normally
show the time and date. In this mode, you can program
the 2524 to display either normal or priority call-ins, both
types, or neither. When there are no call-ins, the display
will resume showing the time and date. Note that this
programming option does not affect the 2524’s front-panel
display.
Automatically Connect Priority Call-ins
This function causes the 2524 to automatically connect
a priority call-in to an optional intercom control panel. If
this function is not selected, a priority call-in will be
signaled at the 2524 and the control panel, but the user
will have to press a button to establish communications

Mode 4 (Monitoring Duration)
The monitoring function has already been explained
under in the “Planning” section of this manual. This setting
--’ determines how long the 2524 will remain connected to
each station as it cycles through the stations selected in
“Comm” Mode 2. Note: This function is not available on
CCOM systems using CTLl.
Step 1. If necessary, enter the “Comm” programming
function. When the “Mode” window flashes, type in “4.”
0 7he “Mode”window willflash “4,” the left “Station”
window will read “du” (“Duration") and the right
“Station” window will showthecurrent setting.
Step 2. Press the right cursor (+> to flash the right
“Station” window. You may type in any number of sec-
onds, from “01” to “15.” When the desired value appears,
push Enter.
0 7%e“Mode” window will flash, and the “Station”
window willlight steadilywith “du”and the valueyou
entered.
Step 3. Enter a different number to select another
“Comm” programming mode, or enter “0” to return to the
Clock Run Mode.
Mode 5 (Call-in Sensitivity-)
This mode is used to adjust Pot RP1 on the 2524 for
-- call-in sensitivity; you must do this before activating the
call-scanning function in Mode E.
Step 1. Select a station to use For this adjustment.
Temporarily install a 1500 R resistor across its call-in wires
(its “T” and “G” terminals on the rear of its relay panel).
Step 2. If necessary, enter the “Comm” programming
mode. When the “Mode” window is flashing, enter a “5.”
0 me “Mode”window willflash a “5,“and the “Station”
windowswill display “000.”
Step 3. Press +.
Q The“Station”windowswillflash.
Step 4. Enter the three-digit Architectural Number of
the selected station. If you enter a wrong number, push
Clear and return to Step 2. When the desired Architectural
Number flashes in the “Station” windows, press Funct.
0 7&edisplay will "freeze” with Mode5 and theArchi-
tectural Number .Thissignifies that the unit is con-
tinuously scanning thestation.
Step 5. Face the back of the 2524 and locate RP1: its
dark blue thumbwheel can be accessed near the left end
of the terminal slot, just to the right of the four-pin
wire-wrap terminal.
Step 6. Use a small, flat-blade screwdriver to turn this
pot completely counterclockwise. Then slowly turn it back
clockwise until the 2524 starts to “beep.” Mark this position
on the pot.
Step 7. Resume moving the pot clockwise until the
beeping stops, Mark this position on the pot, too.
Step 8. Move the pot back to the middle of your two
markings. Remove the resistor from the call-in wires.
Step 9. Push Clear
Q 7he“Mode”window willflash “5, ” and the “Station”
windowswill show “000” steadily.
Step 10. Enter a “0” to return to the Clock Hun Mode.
Step 11. Have someone send normal and priority
call-ins from a nearby and a distant station. If necessary,
try a different setting between your two markings on RP1.
Mode 0 (Run)
When the 2524 is in the Run Mode (“0”), the
Clock/Comm button will toggle the unit between the clock
and communications modes. Normally, there is no reason
to select the communications mode. Whenever a call-in
comes in or the user dials a number, the 2524 will
automatically switch to the communications mode, and
then switch back when all communications have ended.
Putting the 2524 in the “Comm” mode when there arc no
calls in progress will blank the front-panel displays (except
for the “Mode” window).

Work Sheet for Custom Secondary-Clock Code
’ The way you enter this number during programming
will determine whether the 2524 interprets it asminutes or
seconds: after typing the number, press Enter for seconds
or Funct for minutes.
l * You must coordinate three factors to direct a seven-
number block to a particular clock or motor in the clock:
4 You must wire the clock to a particular relay (Out 5,
Out 6, Out 7, or Out 8).
4 In Mode A, you must enter the Custom Code aseither
the first correction code (the only choice when only
one code is used) or the second code. The first
correction code controls Out 7 and Out 8, and the
second code controls Out5 and Out 6
4 Use the seventh number of the block to designate
the odd or even relay.
Note: Although Mode A and the seventh number in
the block each designate two possible relays, in com-
bination they designate only one relay. For example,
choosing the second code in Mode A limits the relay
choice to 7 or 8; entering a “2” in the seven-number
block designates Relay 6or 8. Only Out 8 matches both
these designations.
Example
The following table shows how the correction code for
Rauland analog clocks (regular Correction Code 1) would
be set up as a special code. This is done for illustration
only; you would not usually need to enter a regular code
as a special code (the only exception would be entering

a simple standard code for each seven-number block, in
order to get two corrections in a single code and thereby
free up two output terminals).
Commentary:
Entry 1: “80” = hourly correction.
Entry 2: “00” = start the correction pulse during the
“zero” minute.
Entry 3: “00” = start the correction pulse on the “zero”
second.
Entry 4: “25” = close the relay for 25 seconds per pulse.
Entry 5: “00” = only one correction pulse.

Entry 6: “00” matches Entry 5: no time between pulses, “00” seconds. The difference here is that we are using the

Entry 9: “00” = start the 12-hour correction during the
“zero” minute. Entry 12: (Like Entry 5.)
Entry 13: (Like Entry 6.).
