B. Master/Slave Wiring
Using an additional TMS-12A configured as a slave, up to 24 lines can be sequenced. In the master/slave
configuration, all recordings, statistics, remote access and answer protocols are handled independently between
master and slave.
To enable a TMS-12A to be a slave unit, set switch 12 to the up position, “SL” will be displayed on the display. The
slave lines will be displayed as lines 13 - 24 on the master TMS-12A,TMS-RDMA or the LM-24D. The pins shown
below must be tied together for master/slave operation.

1. NIGHT mode - Incoming calls will be answered on three rings, the night announcement will be played, and
then the call is released.
2. DAY(3) mode - Incoming calls will be answered on three rings, the answer announcement will be played
and then the call will be placed on hold.
3. DAY(5) mode - Incoming calls will be answered on five rings, the answer announcement will be played
and then the call will be placed on hold.
2. Remote Programming
Notes: If switch 1 on the front panel of the TMS-12A is in the down position, the ring delays for Touch Tones 7 and 8 will be
5 and 3 respectively. If switch 1 is in the up position, these Touch Tones will set the ring delays to 2 and 1 respectively. If
you neglect to dial Q1before hanging up from the remote mode, and the TMS-12A line 12 position is connected to PABX
extension or a loop start CO line that does not provide disconnect supervision (CPC), line 12 will not be released from the
TMS-12A until ten minutes after you have hung up. In the Off mode, the TMS-12A will still answer line 12 but will not play an
answering message.
Notes: If you neglect to dial Q1before hanging up from the remote mode, and the TMS-12A line 12 position is connected to
PABX extension or a loop start CO line that does not provide disconnect supervision (CPC), line 12 will not be released from
the TMS-12A for ten minutes after you have hung up. In the Off mode, the TMS-12A will still answer line 12 but will not play

1. To eliminate confusion in key system applications, disable the ringer or program the attendant’s phone not to
ring. The TMS-12A will provide common audible if installed near the receptionist.
2. On incoming calls, the TMS-12A will provide a single warble tone every 4 seconds.
3. Once a line is answered by the TMS-12A, a double warble tone is provided.
4. Warble volume can be adjusted by the potentiometer (marked WARBLE) on the back panel of the TMS-12A.

an answering message.
3. Automatic Night/Day Mode
The TMS-12A will change into the Night answer mode
(switch 7 down) or Off mode (switch 7 up) when 9 - 15 volts
AC or DC is applied across pins 25 and 50.
a. Automatic Timer
For a manual Night answer mode (switch 7 down) or Off
mode (switch 7 up), add a contact closure from the
PABX or a switch at the receptionist’s desk.
b. Night Service Contact Closure
An “A” will be displayed and except for statistics, front
panel switches are disabled on the TMS-12A while in the
auxiliary Night/Off mode. See the diagram to the right.
For automatic Night/Off mode, add a programmable
timer (Radio Shack part # 61-1065 or equivalent) and a
9-15 volt AC or DC power supply. See the diagram to
the right.

In any mode of operation other than remote programming, statistics for Calls Abandoned, Calls Answered, and
Inbound Calls can be viewed.
1. Hold in the data switch, the display will show the current statistic total for the item highlighted by the LED (ABN,
ANS or INB).
2. To select the next statistic, momentarily release, then depress the data switch, and the next statistic item will be
highlighted.
3. The statistics can be reset to zero by depressing the reset button on the front panel of the TMS-12A.
Notes: This will reset the microprocessor and statistics only, the recorded messages will not be lost. However, any
calls holding in the TMS-12A will be dropped. This reset should only be done at a time when the TMS-12A is not
processing calls.
To adjust the playback volume of messages, turn the potentiometer on the front of the unit (marked VOL) clockwise
to increase the volume or counter-clockwise to decrease the volume as shown below. This will change the volume
for all announcements.
The TMS-12A ships with 32 seconds of high fidelity recording capability. Forty seven seconds of recording time is
possible at a lower fidelity by placing protocol switch 4 in the up position. A total of 2 minutes of high fidelity or 3
minutes of lower fidelity recording is possible with the addition of the Viking DRAM-1M (Fax Back Document 055)
memory expansion kit. For faster call processing, make your answer and pacifier announcements short.

Operation
In the DAY(3) or DAY(5) mode of operation, the TMS-12A will answer on the number of rings programmed (1, 2, 3
or 5) as explained in Programming, section B. This allows your receptionist to answer the phone first, if she is
available. After answering a call, the caller will hear the recorded greeting message. While this message is playing,
no other calls can be answered, but all calls that have met the ring delay will be answered as soon as the message
is finished. It is advisable to keep this message as short as possible. After the greeting has played, the caller is
placed on hold and the line that the oldest call is holding on will be displayed on the front panel of the TMS-12A or
on the optional TMS-RDMA remote display (see section D. Options, below). The call may then be released to the
receptionist by picking up that line. Note: Only the oldest call may be released. When the oldest call has been
released, the line that the next oldest call is holding on will be displayed.
While holding, and if recorded, a “Pacifier” message will be played approximately every 30 seconds.
If a call has been holding for longer than 4 seconds, the TMS-12A or TMS-RDMA will produce a double warble tone
audible signal (hold reminder tone) every 4 seconds.
A. Day Mode
In the NIGHT mode, the call will be answered after the programmed ring delay, the night message will be played
and the call will be disconnected.

If the TMS-12A does not release the call to the key system or PABX, follow steps 1 - 3. Note: This is usually
caused by high line current from the C.O. or PABX when the system is located close to a central office.

1. Measure the voltage across tip and ring when the key system or PABX has seized the line. The voltage must be
less than 11 volts for the TMS-12A to recognize that the key system or PABX has gone off-hook and that it
should release the line.

The SQRG-12 Sequential Ring Generator is designed for applications where more than
one person answers incoming calls, or in locations where the TMS-12A front panel
display is not visible. The SQRG-12 eliminates confusion about which line to answer
next by only ringing the oldest call to the key system or PABX.
In some applications it is desirable to have the SQRG-12 ring all calls that are ringing
lines or calls that are holding on the TMS-12A. This is required in many PABX
applications and some key system applications to prevent call crashing (glare) problems

section B).
