Mercury Introduces Its Next-Generation SIO Modules that Extend Integration Capabilities, Enhance Cyber Security, and Provide Seamless Upgrades

Long Beach, CA – February 7, 2018 – Mercury Security, a global leader in OEM access control hardware and part of HID Global, today announced its powerful new family of MR Series 3 Serial Input/Output (SIO) modules that extend integration capabilities, enhance cyber security and provide seamless upgrades for existing Mercury-based deployments. The next-generation SIO modules are built on the Authentic Mercury open platform and provide OEMs, channel partners and end customers the flexibility to choose the controller configuration that best fits their needs.

“Mercury has long been the pioneer in driving open solutions for the access control industry and the new MR Series 3 SIOs are an extension of our commitment to providing customers with value-added products that are built for the future," said Matt Barnette, President of Mercury Security.  “Scalable and designed with cyber security in mind, this addition to our Authentic Mercury product line is ideal for security-conscious organizations seeking to take full advantage of the latest industry standards and technologies to create more trusted, scalable and connected security systems.”

The modules introduce a new level in cyber security with an embedded crypto memory chip that provides a secured layer of encryption to onboard sensitive data. They also support OSDP and Secure Channel Protocol for enhanced connectivity, device management and extended applications such as biometric-focused applications. In addition, support for the federal government profile (FICAM) makes it possible to expand the controller architecture and streamline the implementation of government systems. Lastly, partners and end customers can benefit from the modules in new access control systems or they can be used for seamless plug-and-play upgrades from Mercury’s existing MR series controllers.

The product family includes four serial SIO modules that enable system expansion of Authentic Mercury intelligent controllers as part of Mercury’s distributed architecture.

  • The MR50 enhanced SIO single-card reader interface panel is designed for expansion of a single door.
  • The MR52 dual-card reader interface panel with on-board flexibility connects security devices to a Mercury intelligent controller.
  • The multi-device MR16OUT door interface panel is dedicated to point control and monitoring.
  • The MR16IN interface is for status annunciation and alarm monitoring applications.


The MR Series 3 Serial (SIO) modules feature Mercury’s new “red board” design and are available through the Mercury partner network. Click here for more product information.
