Remote I/O RF Door Expansion Board
Product Code: SEB-721
Key Features
– On-board RF receiver.
– Can utilise up to 4 buttons
– Transmitters can be uniquely linked to an individual
– 16 units can be connected per door controller
– Robust RS-485 controller communication
– 4 Digital Inputs
– 2 Relay Outputs (Potential free/Powered output)
– Rotary coded address switch for easy addressing
Installation
The SEB-721 offers a seamless integration with both the SDC-650 and SDC-620 Controllers, providing an expanded and flexible access control solution that can be tailored to meet the unique needs of your organization.
Communication with the SDC-650 or SDC-620 Controllers is seamless, facilitated by the RS-485 Reader Network through the onboard connector. Each device is assigned a unique device address via an onboard rotary switch. Once communication is established, the SDC-650 or SDC-620 Controller will detect the device and indicate this connection status on the controller LCD display in the configuration section. Managing access control configurations for doors, readers, and more becomes effortless using the intuitive SACS software.
For a trouble-free installation experience, diagnostic LEDs are strategically placed close to their relevant terminals, providing valuable support and guidance. End-of-line resistors can be effortlessly integrated into the RS-485 Reader Network circuit using the indicated jumpers, eliminating the need for external terminating resistors.
The dual-mode relays can be set as powered outputs or potential-free relays (using the indicated jumpers), for you to easily switch any lock or electrical device, ensuring maximum control and flexibility over your access control infrastructure.
Operation
The SEB-721 Remote I/O RF Door Expansion Board operates by connecting to the RS-485 Reader Network ports on the SDC-650 Multiple Door Controller or SDC-620 Wiegand Controller and expands the remote input, output and access control capabilities of the Controller. Once connected and configured, the SEB-721 can receive inputs from external devices, such as door contacts or motion sensors, and send outputs to devices such as locks or buzzers.
In addition, it facilitates the use of RF Remote Transmitters for controlling access at the remote location.
About the product
About the Product
The SEB-721 Remote I/O RF Door Expansion Board is an advanced addressable expansion device designed to extend the Input and Output capabilities of the SDC-650 Multiple Door Controller and SDC-620 Wiegand Door Controller. The device connects directly onto the RS-485 Reader Network of the controllers, providing additional I/O functionality and enabling the use of code-hopping or rolling-code 433MHz RF remote transmitters as an alternative to traditional proximity card or biometric readers.
The SEB-721 can be used as a remote door controller, allowing inputs and outputs to be positioned closer to the access point. This helps reduce potential voltage drops when the controller is installed further away from the door, while also providing a practical solution for remotely located access points requiring additional I/O control.
Featuring 2 relay outputs and 4 programmable digital inputs, the SEB-721 offers a flexible and versatile solution for a wide range of applications. The device can also operate as a remote connection point for additional I/O requirements, enhancing the overall flexibility of the access control system.
The integrated RF module allows users to operate access points using code-hopping or rolling-code RF remote transmitters. Each remote can support up to 4 buttons, with each button capable of being assigned a different function, providing greater control and convenience.
Using remote control access instead of proximity cards or biometric readers provides additional flexibility, especially for access points such as automatic gates, vehicle barriers, and areas where adequate weather protection is not available. Unlike standard gate remotes, the SEB-721 records all access transactions, ensuring improved security monitoring and user accountability.
Remote transmitters are allocated to users through the SACS software in the same way as RF tags or biometric templates. This allows full access management capabilities, including scheduling, anti-passback, and zone control, from a central location.
The SEB-721 supports up to 30,000 or more remote users and can control up to 4 access points, making it an ideal solution for organisations looking to expand their access control capabilities with a flexible, reliable, and transaction-based remote access solution.
