SES RPT1ACOMM, INCLUDES NIC, MODEM, MUI, SERIAL PORT, TEC1A
The SES RPT1ACOMM is the full communication option board for compatible TEC1A telephone entry systems. It is used when the TEC1A needs network communication through a NIC, modem access, MUI line-sharing capability, and serial-port support in one board-level package.
This is the row to treat carefully when a customer is trying to restore remote programming, Ethernet/network communication, or a premium TEC1A communication option. It should not be substituted for the MUI-only board or modem-only board without checking the existing board label and model configuration. On older systems, communication issues may also involve phone service, network settings, surge events, wiring, or software setup rather than the board alone.

Technician Note
This is the most complete TEC1A communication option in this batch. Use it only where the unit and site programming method call for NIC, modem, MUI, and serial communication together.
Before Ordering
- Confirm TEC1A model and option package.
- Compare the existing communication board label and connectors.
- Verify whether the site uses Ethernet/NIC, modem, serial, or shared-line MUI features.
- Check network settings, telephone line condition, and surge history before assuming the board is failed.
- Back up or document programming before replacement whenever possible.
Professional Advisory
Network and telephone-entry communication repairs should be performed by an access-control technician familiar with SES programming software and site communication wiring.
Product Questions & Answers
What functions does RPT1ACOMM include?
It is written for TEC1A applications needing NIC/Ethernet, modem, MUI, and serial-port communication functions.
Is this the same as NIC3?
No. NIC3 is a network interface card for CAT and most TEC products. RPT1ACOMM is a TEC1A communication board package.
Can this replace RPT1AMUI?
Only if the TEC1A is being equipped for the full communication package. RPT1AMUI is the MUI-only module.
Does this board include reader inputs?
The row is focused on communication functions. If reader input is needed, compare the TEC1A 2-reader board option separately.
Why should the existing board be checked first?
TEC1A systems can have different option-card combinations. Matching the installed board avoids buying the wrong communication package.
