WARNING: Changes or modifications to this product not expressly approved by
the party responsible for compliance could void the user’s authority to operate this
equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or tele
vision reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
-
-
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and receiver.

FOR UNITS EQUIPPED WITH AN INTERNAL MODEM (24A715M)
NOTICE: This equipment complies with Part 68 of the FCC Rules. On the mounting
panel of this equipment is a label that contains, among other information, the FCC Regis
tration Number and Ringer Equivalence Number (REN) for this equipment. If requested,
provide this information to your Telephone Company.
The registration jack USOC for this equipment is (RJ-11). An FCC-compliant telephone
cord and modular plug is provided with this equipment. This equipment is designed to
connect to the telephone network or premises wiring using a compatible modular jack,
which is Part 68 compliant. See installation instructions for details.
-
The REN is useful to determine the quantity of devices that may be connected to the tele
phone line. Excessive RENs on the telephone line may result in the devices not ringing in
response to an incoming call. In most, but not all areas, the sum of REN of all devices
should not exceed five (5). To be certain of the number of devices that may be connected
to a line, as determined by the total REN, contact the local Telephone Company.
If your telephone equipment (Modem) causes harm to the telephone network, the Telephone Company will notify you in advance that temporary discontinuance of service may
be required, but if advance notice isn’t practical, you will be notified as soon as possible.
You will be advised of your right to file a complaint with the FCC if you believe it is
necessary.
Your Telephone Company may make changes in its facilities, equipment, operations,
or procedures that could affect the operation of your equipment. If they do, you will be
given advance notice so as to give you an opportunity to maintain uninterrupted service.
This equipment may not be used on public coin service provided by the Telephone
Company. Connection to party lines is subject to state tariffs. (Contact your state public
utility commission or corporation commission for information.)

General Information
This installation manual covers the Model 24A715 and 24A715M Master Clocks. Both
clocks are installed and programmed in similar fashions. The main difference between
the clocks is the 24A715M is equipped with a built-in modem capable of communicating
with a PC, or for synchronizing with the NIST Atomic Clock. Both clocks have eight cir
cuits that can be programmed to ring bells or activate circuits for up to 99 seconds, and/or
synchronize the time on three types of clock systems (any two manufacturing brands of
clocks listed in Appendix B, plus compatible RS-485 time synchronization devices). You
can program up to 512 events to activate single or multiple circuits on a given day and
time. The 24A715M can also connect to a PC running Microsoft Windows
tional MasterLink™ software available from Lathem.
Unless otherwise specified, “master clock” refers to both units in this document.
The master clock can be programmed with these functions:
• User password
•
Date and time
•
Clock types to synchronize
•
Manual bell control (example: sounding a fire alarm)
•

Using the Installer’s Hooks to Hang the Display Below the Backbox
When mounting the clock in either semi-flush or surface installations, the hooks on the
back of the display unit mounting plate can be used to hang the display unit below the
backbox to allow access for circuit testing and programming. See Figure 1-2.
To use the hooks:
1. Remove the two screws securing the display unit to the backbox.
2. Lift the unit up and away from the backbox, leaving the ribbon cable attached. Two
rivets at the bottom of the cover will prevent you from lifting it straight up.
3. If you have a semi-flush installation, remove the green communications connector
plug from the back of the display unit. This allows the unit to sit flat against the wall.
4. Swing up the two hooks on the back of the unit and hook them over the bottom edge
of the backbox. You now have access to the key pad for making program changes or
manually activating the circuits, and access to the relay and connector blocks inside
the backbox.

Rack Mounting
The two L-shaped brackets and the box cover supplied with the master clock can be used
to install it in a standard 19-inch (48.3 cm) rack. See Figure 1-3 on page 1-7.
To rack mount the clock:
1. Place the master clock on its back with the display unit facing up and the key pad to
the right.
2. Remove the two screws securing the display unit to the backbox.
3. Lift the display unit up and away from the backbox. Two rivets at the bottom of the
cover will prevent you from lifting it straight up.
4. Unplug the ribbon cable from the back of the display unit to disconnect the power
supply.
5. Detach the display unit from the wall mount plate by removing the four screws on the
back of the display unit. (IMPORTANT: Do not lose these screws. They are a specific
length so they do not interfere with the circuit board inside the display unit. Using any
other screws to attach the display unit to the case will void any warranty.)
6. Remove the rectangular knock out near the top of the power supply. See Figure 1-3
on page 1-7.
7. Using the four screws removed in step 5, attach the display unit to the bottom of the
power supply. To assist you, there are holes opposite the four screw holes where you
can fit a #1 Philips screwdriver with an 8-inch (20.3 cm) blade.
8. Reconnect the ribbon cable from the power supply to the display unit.
9. Remove the two screws from one side of the display unit, then use them to attach an
L bracket to the side of the unit. See Figure 1-3 on page 1-7. Repeat to attach the
other bracket to the other side.
10. Mount the unit in the rack.
11. Wire the clock before attaching the box cover. See Wiring the Master Clock on
page 1-8.
12. Attach the cover to the power supply using four 6-32 screws. Two of these screws

Wiring the Master Clock
This section provides instructions on wiring the power source, secondary clocks, and sig
naling devices to the master clock. It does not cover the connection of the optional
modem, a computer, any RS-485 devices, and a power source for the optional remove
schedule selector. Instructions for those devices are provided in Appendix C.
Stranded wire is recommended for use inside the power
supply box, as it allows a firm connection to the quick
connect terminals. There is also less chance of stranded
wires interfering with the components on the relay board.
If solid wire must be used, join the stranded wire to the
solid wire in another box.
The master clock is supplied with quick connects. These
should be attached to the wires as necessary so that the
wiring can be connected to the terminal blocks as shown
in Figure 1-4.

into the Terminal Block
—WARNING—
Failure to properly connect the ground wire
can increase interference and cause
unsafe operating conditions.

Wiring Procedure
Figure 1-5 on page 1-9 shows terminal blocks P1 through P4, located on the PCB in the
power supply backbox. Follow the steps below the figure to wire the clocks, power
source, and signaling devices to the master clock.
Notes:
•
Circuits CKT1 through CKT4 designate bell controls. Circuit pairs CKT5/CKT6
and CKT7/CKT8 can function as clock synchronization circuits or as bell controls.
•
MOVs (Metal-Oxide Varistors) protect all relay contacts.
•
Voltage-select jumpers connect to terminal block P4 for 120Vac operation. For
clocks that must run at 220/240Vac, remove the 120V jumpers and install one
jumper wire for the 240V selection. The system will automatically adjust for oper
ation at 50Hz or 60Hz at either voltage. Also see Terminal Block P4 on page C-2.
•
Some clock setups may require external diodes or MOVs. See the wiring diagram
for your type clock (see Appendix B).

Master Clock Terminal Blocks
1. Wire the power source to P4 as shown in either Figure C-1 or C-2 on page C-2.
Note:
The master clock is shipped set up for 120Vac operation. To wire it for 220/240Vac,
change the jumper settings as shown in Figure C-2.
—WARNING—
DO NOT turn on AC power, and keep the
power/relay unit’s toggle switch OFF until you
complete the rest of the wiring in this section.
—WARNING—
Applying 220/240Vac power to a system not
set up for that voltage level can severely
damage the electronic parts.

2. Wire the secondary clocks to P1 and/or to P2. See Wiring Secondary Clocks on
page B-2 for complete instructions.
Note:
You may need to add external metal-oxide varistors (MOVs) or diodes to synchronize
a specific clock type. See the clock wiring diagrams in Appendix B.
3. Wire the signaling devices to P3. See Typical Signal Device Wiring on page C-3.
Note:
If the master clock is not connected to any secondary clocks, signaling devices can be
wired to P1 and P2.
4. Although the master clock is fused internally to protect its electronics, the incoming
AC line must also be fused as required by your local electrical code. Dukane recom
mends connecting the unit to a dedicated 10-amp circuit.
5. Turn the toggle switch in the power supply to the ON position.
6. Complete any mounting steps in the previous section, Mounting the Master Clock
on page 1-2.
-
Synchronizing Non-Compatible Clocks by External Pulse
The master clock can synchronize to other systems if necessary. For example, you have a
non-compatible time clock that cannot be synchronized by the master clock, but it has a
built-in bell ringer. By shorting terminals 7 and 8 on terminal block P4, or terminals 6
and 7 of the communications terminal on the back of the display unit, the master clock
will immediately reset to 00:00 (midnight). If you can program the other device to close
its circuit at 00:00 (midnight) then the two systems will remain reasonably in sync.
—WARNING—
DO NOT apply power to the external
pulse-sync terminals. Simply close
the circuit for 1–5 seconds.

Setting Up the Master Clock
Once the master clock is installed, it is ready for programming. This chapter covers the
programming instructions needed to set the master clock for operations.
Note:
To completely clear the clock of all settings and reset the master clock to its factoryshipped configuration, press the following number sequence on the master clock key
pad: 355379768274. This clears all programmed schedules and reinitializes the
master clock.
Programming Relays
If the master clock will control one type of secondary clock, relays #7 and #8 on terminal
block P1 are used for this purpose. If the master clock will control a second clock type,
relays #5 and #6 on terminal block P2 are used for those clocks. See Table 2-1.

Here are some possible ways to program the master clock relays:
•
Eight bell zones that can last from 1 to 99 seconds. Use this setup if the master clock
will not be used to synchronize secondary clocks. (Note: The maximum closure time
provided by this master clock is 99 seconds. Closures longer than 99 seconds will re
quire an external latching relay. This is not provided by Dukane.)
•
Six bell zones and one wall clock synchronization control. Use this setup if the master
clock will only synchronize one type of clock in one string.
•
Four bell zones and two wall clock synchronization controls. Use this setup if the mas
ter clock will synchronize two clock types, or if there are two strings of clocks
(typically 20 to 35 clocks to a string).

Programming Functions
This section explains how to put the master clock in program mode and configure the
necessary functions to get the master clock running. For definitions of all functions, key
pad commands, and the bell test, see Section 3—Function List.
The master clock is normally in clock mode, displaying the date and time. To access pro
gram mode, press [#] on the key pad. Pressing [*] stops programming so you can re-enter
a setting or quit.
Entering the Password
The administrative password provides access to both advanced functions and user functions.
The user password only provides access to user functions.
The factory-programmed user password is 000000, and can be changed (see page 3-6).
User passwords are explained further in the Master Clock User Guide, document
427-07-00047.
The factory-programmed administrative password is 332537, or DEALER (as spelled out
on a telephone key pad). It cannot be changed.
Note:
To keep the administrative functions secure, only give this guide to authorized personnel.
The following shows the key sequence to enter the password, and the resulting clock
display:
