TSA-3SB — Telephone Supervisory Adapter with Switch & Beep

The TSA-3SB is used to connect your Omnicron recorder to a specific telephone set. It can be used with both single and multi-line telephones. The unit has a BEEP tone generator to remind you that your conversation is being recorded and an ON-OFF switch to disable recording.
The TSA-3SB is supplied with cables and connectors that have been wired to meet most standard applications. Both the volume and interval of the BEEP tone are adjustable.
1. Unplug the handset (or headset) cord from your phone and plug it into one of the two jacks on the adapter ("A" on the drawing below).
2. Using the short cable which was supplied with the TSA-3SB, plug one end of the cable into the handset jack on your phone and the other end of the cable into the remaining jack on the TSA-3SB adapter ("A" below). Your telephone should now function normally since its handset has been reconnected through the TSA-3SB.
3. The TSA-3SB can now be connected to your Omnicron recorder. Connect the cable with the small plug labeled REM to the REM (Remote) jack on your recorder ("B" on the drawing below). Connect the other cable with the plug labeled AUX to the AUX (Auxiliary) jack on your recorder ("C" on the drawing below).
4. Locate a convenient spot on your phone to mount the adapter ("A" on the drawing below). Insure that it will not interfere with the operation of the phone. Use the double stick foam tape and cable ties which are included. The TSA-3SB should be placed near your phone so that you can operate its ON-OFF switch and see the recording light when using the phone.
5. Plug the AC power adapter ("D" below) into a suitable wall outlet.


TSA-3SB Typical Installation photo

With the TSA-3SB’s ON-OFF switch in the "ON" position it feeds the audio from your telephone handset to your recorder. It detects when the recorder is recording and generates a BEEP tone which is fed to the handset of your telephone. With the switch in the "OFF" position, audio is removed from the recorder so that it will not record your conversation and the beep will stop after a short delay. Operate the recorder as outlined in its owners manual.
The BEEP tone circuit senses that your recorder is recording through the cable that is plugged into the recorders REM jack. The BEEP can be eliminated either by disconnecting the REM cable or unplugging the AC power adapter. The green light on the front of your TSA-3SB will be lit whenever you are recording and the BEEP circuit is active.


On the bottom of the TSA-3SB is a switch for setting the BEEP tone to either a high level for older style telephones, or to a lower level if it is used with new style telephones.
The "HANDSET TYPE" switch is accessible through a hole on the bottom of the unit. If the BEEP is extremely loud, slide this switch to the "NEW STYLE PHONES" position. If you do not hear the beep, or it is very weak, set it to the "OLD STYLE PHONES" position. The volume of the BEEP can also be changed by adjusting the "BEEP LEVEL" calibration adjustment which is accessible through a hole on the bottom of the unit.
A calibration adjustment on the bottom of the unit can be used to change the interval between beeps. The beep interval should be set so that the beeps occur every 15 seconds.
If the unit fails to work, recheck all connections and test your recorder to see that it is operating properly. Telephone assistance is available from your place of purchase, or directly from Omnicron Electronics at the phone numbers listed below.
