TSA-3A TELEPHONE SUPERVISORY ADAPTER

DESCRIPTION
The TSA-3A is used to provide a simple and inexpensive method of connecting supervisory monitoring equipment to the handset circuit of a telephone. It is usable on most telephone styles which have a standard modular handset or headset jack. It provides isolated and attenuated microphone (MIC) level output.

INSTALLATION
The TSA-3A is supplied with cables and connectors which have been wired to meet most standard applications. It can be customized to meet unusual requirements. Consult your place of purchase if cables are required with non-standard lengths, connections, or circuitry. On the back of this instruction sheet is a drawing that shows a typical installation.

1. Unplug the handset cord from your telephone set and plug it into the jack on the TSA-3A adapter.

2. Plug the short TSA-3A cable into the handset jack on your phone. Your telephone should now function normally as you have simply connected a short extension into the handset cord.

3. The long TSA-3A cable can now be connected to your supervisory equipment (cassette recorder, monitor amplifier, etc). The TSA-3A couples the handset audio through an isolation transformer and attenuation circuitry so that you will be able to monitor conversations on the phone at microphone level. Both sides of all conversations on the handset or headset that is plugged into the TSA-3A can be monitored. If your telephone does not use standard connections, the unit may have to be re-wired so that the recorder is connected to the correct wires.

If your monitoring equipment interferes with the operation of your phone in any way, or if your monitoring equipment is not designed to be connected to your telephone in this manner, a different means of interconnection may be required.

4. Locate a convenient spot on your phone to mount the TSA-3A. Insure that there is enough slack in the cables so that they can be easily un-plugged, if required, and that it will not interfere with the operation of the phone. Use the double stick foam tape and cable ties which are included with each TSA-3A to attach it to your phone.
