2524 Master Clock Installation
Associated Equipment
This list is representative only. The 2524 is designed to be
highly flexible. Therefore, it is not practicable to list every
possible application in this manual. What is listed, the attached
wiring diagrams, and the descriptions of the outputs should
cover most applications and give you some ideas for working
out special installations.
Print-out Explanation
<Zones 1234 The event occurred on Zones 1,
12:45PM 9-30-92 2, 3, and 4 at 12:45 p.m. on
9/30/92.
< Time 0O:OO:OO A synchronization command

Clock Equipment
Secondary Clocks: The 2524 can correct all of Rauland’s
secondary analog and digital clocks. It can also correct all of the
widely distributed clocks from other manufacturers (seethe list
and the wiring diagrams at the end of this manual). Finally, you
should be able to program a special correction code for virtually
any other clocks that are not handled by the standard codes.
Gnd: This is a circuit common, which also serves as the
ground.
+5V: This output can be used as an auxiliary power supply
(5 VDC, l00mA). Its most common application is to power a
2417 Correction Adapter Module, which is used with the “DIG"
output (explained next).
Clock Power Supplies: Rauland’s 2415 24-VAC and 2416
120-VAC Power Supplies can handle up to 25 secondary clocks
per unit. To power more than 25 digital clocks, refer to the wiring
diagrams at the end of this manual.
DIG: This output sends serial data pulses that can be used to
control digital secondary clocks. This application requires one,
but can drive up to five, 2417 Correction Adapter Modules.
Buffers: The 2524’s outputs each have a relay that can handle
up to five amperes of current at up to 120VACor 30 VDC. Should
the equipment you connect to a given output require more
power, you can accommodate it by using buffers. The 2418 AC
Buffer can switch up to 10 amperes at 110VAC, and the 2419 DC
Buffer can switch up to five amperes at 60VDC(the higher voltage
is needed by minute-impulse clocks). Wiring two or more buffers
to split the load increases the total load that the output can
handle.
GND: A chassis ground, which also serves as the circuit
common. It should be used when connecting a 2417 Correction
Adapter Module to a 2524.
OUTl-OUT8: These eight pairs of screw terminals are for
the relay contacts, to which you can connect signaling devices,
secondary clocks, equipment, or relay panels. Each relay is
normally open, can handle up to five amperes of current at 30
VDC or 120 VAC, and has an arc-suppression circuit connected
across it.
2417 Correction Module: This is used to enable the 2524’s
“DIG” output to control a power supply with up to 25 digital
secondary clocks. Using this module can free output terminals
for device control.
-GND-: These three screws on the far right are for connect-
ing the unit to 120-VACpower. The middle terminal is for chassis
ground, and the two outer (-) terminals are for the hot and
neutral lines.
Output Terminals
In the following descriptions, the 2524’s rear terminals are
described in order, from left to right, asviewed from the rear of
the chassis.
The following terminals are used when the 2524 controller is
used in the communications mode of operation. Refer to the
2524 ChronoCom Installation manual (KI-1628) for more in-
formation on these terminals.
In-Gnd-Out: These four wire-wrap terminals (there are two
“GND" pins) can be wired to a standard RS-232 cable and
connected thence to a computer or a modem for remote pro-
gramming, or to a serial printer to provide a log of event
executions (seethe sample log below). For the wiring to the cable,
seethe attached KM0991.
In: Connecting another master clock here enables it to
control the time in this unit. When the 2524 receives a valid
synchronization signal from another Rauland master clock, it
changes its time to 12:01 a.m.
RP1: Used to adjust for priority calls in ChronoCom systems.
A Amp: The connection of the main power amplifier.
Music Amp: The connection of a music amplifier.
Answer: Used to answer call-ins with a remote phone. (Note:
not available on TL systems.)
LCD (Z, +, -): The output used to drive a remote VFD display
or an LCD Sidecar Display.
Reset: Used to reset the system after an all-page or an
intercom call. (Note: not available on TL systems).

Installation
Jumpers
Before enclosing the unit in a rack, make sure that its internal
jumpers are set the way you want them. The Baud-rate jumper
affects only a computer that can be connected for diagnosing
and programming the 2524 (using the optional T2524 Diagnos-
tic Program). If you want to “disable” the programming (to
prevent future tampering), you’ll have to program the 2524 with
the jumper in the “EN” (“enable”) position before changing the
jumper to the “DIS” setting and enclosing the unit (see the
clock-programming manual, KI-1733). The jumper locations are
shown in the attached drawing IL0341.
Rack Mounting
The 2524 is designed for mounting in a standard 19-inch rack.
No special treatment is required if other equipment is mounted
next to it.
Step 1. Locate 31/2inches of rack space where the 2524 will
be mounted. Slide the four supplied #10 Tinnerman clips over
the mounting holes in the channel rails. (If the channel rails
holes are tapped, do not use these clips.)
Step 2. Prepare the mounting screws by placing a black flat
washer and then a fiber washer over each one (all supplied).
Step 3. Position the 2524 in the rack, align its front-panel
mounting holes with the Tinnerman clips, and use the four
prepared machine screws to secure it to the channel rails.
Wiring
Follow the attached wiring diagrams and refer asnecessary to
the earlier descriptions of the terminals and accessories. What
follows here are a few helpful details.
Screw-Terminal Cover
To access the screw terminals, remove the shield from the
bottom of the electrical box that is attached to the rear of the
chassis (on the right, as viewed from the rear). Remove the two
sheet metal screws, then disengage the cover’s tabs from the slots
in the 2524’s chassis by sliding the cover to the left and then
pulling it straight back. Reverse this process to re-secure the
cover.
For a permanent installation and to protect against shock
hazard, run the 120-VAC wires through conduit attached to one
of the cover’s knockouts. If you are running both high- and
low-voltage wires, use separate conduits and knockouts. For any
low-voltage wires run in conduit, use the knockout nearest the
Zone/Output terminals. The 120-VAC wires should be 14-AWG or
heavier-gauge, and they should have an added six-inch loop
inside the cover.
Signaling Devices and Equipment
The attached KM0987 shows how signaling devices and
equipment can be connected for each zone. If two or more
signaling devices are required for a given zone, they can be
connected in parallel and share the connections to the relay
terminals for that zone. For loads that exceed the built-in relays’
rating, install 2418 or 2419 Buffers (see“Associated Equipment”
in the earlier part of this manual).
The 2524 can activate these devices for up to 59 seconds or
“latch” them on for any number of minutes, up to a week. For
more information, refer to “Clock Mode 5” in the 2524 clock-
programming manual, KI-1733.
Correctable Secondary Clocks
The 2524 can simultaneously correct two different types of
secondary clocks through its Zone/Output terminals and Clock
Mode A programming. The tables and “Figure” drawings at the
back of this manual show how to hook up virtually every
widely-distributed secondary clock. It is also possible to make a
custom code for a clock (in Clock Mode B programming).
Use the secondary-clock table to find the associated drawing
for each type of clock. The drawing will tell you the standard
code and show the wiring needed.
If only one correction code is used, then Out 7 and Out 8 must be
used to connect the secondary clocks. Out 7 will send out the
“X" corrections, and Out 8 will send out the "Y" corrections.
If a second correction code isprogrammed, the secondary clocks
for this code must be connected to Out 5 (for the “X’ corrections)
and Out 6 (for the “Y” corrections).

2524 Master Clock Installation
Separate Telecenter@ Systems
i .... The 2524 can be wired to a Telecenter system and cause the
latter to send the tones. In this arrangement, the Telecenter
software defines the zones. Telecenter V systems have eight zones,
so the 2524 can control them individually. In contrast, Telecen-
ter 5500 systems provide only its first four paging zones for time
tones. On a TC5500 system, the 2524 also synchronizes the
system clock.
Use the appropriate table below for the wiring. Note that the
“A” side of each Zone/Output terminal used is connected to the
corresponding zone input on the Telecenter system, but the “B”
sides are jumpered together and connected to a common on the
Telecenter system.

3. Use 22-AWG tinned cable for all connections.
4. Do not connect the TCIV ribbon cable to the 2524.
5. * Usually the 2524’s “Zone/Output” terminals are used for
correcting secondary clocks and so are not available for connec-
tion to a Telecenter system.

those Zones ring, or (c) not ring at all.
Telecenter System 21
Seethe Telecenter System 21 drawings manual, Kl-1767.
Turning on the 2524
When power is applied to the 2524, it displays “0” in the
“Mode” window, the current time in the “Time”window, and a
flashing “P’” (to indicate that there was a power failure) in the
“Sched” window. The unit comes up in the Clock mode of
operation. Push any key to stop the flashing “P.”
Note: When the clock is turned on for the first time or at any
time when the battery was “disabled,” the “Time” windows may
show random numbers. In this case set the date and the time
(Clock Modes 1 and 2-see KI-1733).
7/96 Page 5

Functional Descriptions
This section explains the way the 2524 operates some special
features. The regular operations are explained in the section on
the individual outputs, above.
First, the 2524 will activate the Telecenter system’s time tones by
1. Activating the appropriate “Zone/Output” relays.
Music Events
A clock event can specify that a time tone be followed by one
to fifteen minutes of music. The 2524 handles this in two
different ways, depending upon whether or not it is using
speaker relay panels.
Next, the 2524 ends the tones and sends out the music (or other
program source) by:
2. Deactivating its “Zone/Output” relays.
3. Switching the Off Bus to the music source’s output.
With Separate Telecenter@ Systems
Finally, the 2524 ends the event by:
In this case, Clock Mode E programming specifies “0” for
the number of SC25s, and its outputs are connected to a
Telecenter system to provide time-tone signals. Since the 2524’s
ribbon cable does not connect to the speaker relay boards, it
cannot send music to individual rooms or to zone circuits.
However, it can control the music output terminal on the rear
of the 2524 and activate it during the programmed music
duration of each event on the 2524 Master Clock. An external
DPDT relay may be connected to this terminal and can switch a
dedicated music amplifier to the “Off’ Bus on any one speaker
relay panel (TC4130) or to all speaker-relay panels in the system.
4. Disconnecting the Off Bus from the output of the music
source.
As Controller of Telecenter 1100
Communications Systems
Music during class change is a built-in feature of the 2524
controller in Telecenter 1100 systems. For each programmed
event, the music can be sent out to any or all zones for 1 to 15
minutes. Music may also be sent to any desired room by dialing
the program from a keypad.
