SES RPK4DR Four Door Wiegand Input Module for CAT and TEC Systems
The SES RPK4DR Wiegand input module is a four-reader expansion/service module for compatible SES CAT and TEC entry systems. Where a property uses a CAT or TEC panel for both telephone entry and controlled credential access, this board helps support multiple Wiegand reader points through the SES controller. It is used in access-control layouts where more reader inputs are needed than a smaller two-door module can provide. The module must be selected carefully because reader capacity, controller generation, software, credential format, and relay/door assignments all affect whether the system will operate correctly. It should not be treated as interchangeable with RPK2DR or unrelated relay expansion boards.

Technician Note
Four-reader expansion depends on more than the board. Reader wiring, door relays, credential database, software capacity, and CAT/TEC configuration all need to match the intended door layout.
Before Ordering
- Confirm the SES controller supports RPK4DR/OPTK4DR.
- Verify four-reader capacity is required and supported.
- Check reader voltage, Wiegand format, facility code, and credential programming.
- Compare existing board number, cable, and connector layout.
- Do not substitute for RPK2DR unless the door count and controller programming support the change.
Important Ordering Warnings
- Adding reader capacity may require system programming and should be tested at every door or gate after installation.
Professional Advisory
For telephone-entry, access-control, camera, relay, or communication-board service, disconnect power where required and use a qualified access-control technician when wiring, board replacement, network setup, or field programming is outside the installer's scope. Do not bypass required gate, door, or life-safety devices.
Product Questions and Answers
What does RPK4DR add to an SES system?
It provides four-door Wiegand reader input capability for compatible SES CAT and TEC systems.
Is RPK4DR an exact replacement for RPK2DR?
No. It is a different module intended for four-reader applications, while RPK2DR is for two-reader applications.
Can this be used with card readers and keypad readers?
It can be used with compatible Wiegand output devices when supported by the SES controller and programming.
Does it include readers?
No. It is the input module only unless a supplier package states otherwise.
What is the most important fitment check?
Confirm the CAT/TEC model, board generation, door count, Wiegand format, and software/controller capacity.
