SES RPAUDIOHARN, AUDIO HARNESS, CAT/TECs
The SES RPAUDIOHARN is a replacement audio harness for the audio circuit used in select CAT and TEC telephone entry systems. In a telephone entry unit, the audio harness helps connect the board, speaker, microphone, or related audio components depending on the cabinet layout. When the harness is loose, corroded, broken, or pinched, the entry unit may still power up and place calls but have poor, one-way, noisy, or intermittent audio.
This part is intended for CAT and TEC applications that call for RPAUDIOHARN. It is not a universal SES audio cable, and it should not be confused with the TEC1A-specific RPT1AAUDIOHARN or microphone/speaker assemblies. Before replacing it, inspect the speaker, microphone harness, board connector, and cabinet for water damage. Many audio complaints come from more than one issue, so matching the harness and checking the related audio parts is important.

Technician Note
Audio complaints should be diagnosed as a circuit, not only as a harness. Check the speaker, microphone, board connector, telephone line or communication interface, and cabinet moisture before deciding which audio part has failed.
Before Ordering
- Match the harness part number and the SES product family before ordering.
- Compare connector count, terminal block style, wire routing, and board location against the original harness.
- Check for moisture damage, loose terminals, corrosion, pinched wires, or overheated connections inside the cabinet.
- Do not choose a harness by appearance only; similar SES harnesses may be wired for different boards or product generations.
- Label existing wiring before removal so the replacement harness can be installed in the same circuit location.
Professional Advisory
Harness replacement should restore the original wiring path, not change the way the entry system is powered or connected. Do not bypass protective devices, required safety inputs, fire access equipment, or gate operator controls. If wiring is burnt, shorted, or repeatedly failing, have the system inspected before replacing parts.
Important Ordering Warnings
- Do not substitute this CAT/TEC audio harness for the TEC1A-specific RPT1AAUDIOHARN unless SES documentation confirms it for the exact unit.
- If audio failure followed lightning, surge, or water damage, inspect the control board and audio components before replacing only the harness.
Product Questions
What does the SES RPAUDIOHARN do?
It is an audio harness used in the audio circuit of select SES CAT and TEC telephone entry systems.
What systems is RPAUDIOHARN commonly used with?
It is commonly listed for CAT and TECs where the SES parts diagram calls for the CAT/TEC audio harness.
No. RPT1AAUDIOHARN is listed for TEC1A, while RPAUDIOHARN is listed for CAT and TEC applications.
Can a bad audio harness cause one-way audio?
Yes. A damaged or loose harness can contribute to one-way, weak, noisy, or intermittent audio, although the speaker, microphone, board, and communication line should also be checked.
Should I replace the speaker or microphone at the same time?
Only if diagnosis shows they are damaged or degraded. The harness, speaker, microphone, and board connector should be inspected together.
