Protege DIN Rail
8 Port F/2F Reader Expander


The Protege Half DIN Rail 8 Port F/2F Reader Expander provides sites using legacy end-of-life Casi-Rusco hardware, and those operating F/2F card readers, with a seamless migration path to the Protege GX system.

  • 8 reader ports using the F/2F protocol
  • No rewiring of existing readers required
  • Simply unplug the existing Casi-Rusco Secure Perfect/Picture Perfect or GE/Micro5 reader connection and fit to the Protege F/2F Reader Expander
  • Monitor door position contacts and Request to Exit devices over standard F/2F protocol


Many existing Casi-Rusco Secure Perfect, Picture Perfect and GE Micro-5 systems require replacement or upgrade as the platform reaches its end of life. Installations can be large (10,000+ doors) which makes replacing the entire system cost prohibitive. The Protege 8 Port F/2F Reader Expander is a cost effective solution giving integrators the ability to take over these sites without the need to replace/rewire existing readers.

  • Replacement product is mounted into existing security hardware enclosures
  • There is no need to re-wire the system as it uses the existing wiring to card readers and other devices
  • Allows continued use of existing cards, saving the time, cost and inconvenience of replacing cards

Installation simply involves removing the circuit boards and card cage from the existing Casi-Rusco enclosure. DIN Rail mounting strip is then installed inside the enclosure, and the replacement Protege hardware modules connected. This provides a more robust solution than that offered by other providers which simply replace the circuit boards and continue to use the outdated and fragile card cage.

Beyond leveraging your existing investment, moving to Protege GX provides a scalable solution that expands with your business. The modular design and scalable licensing model makes Protege GX suitable for everyone – from small single door systems right through to large multi-national corporations. Modular expansion allows the system to grow with you and proves to be very cost effective as you only add Expander modules and optional functionality as you need.

Device power is supplied from a 12VDC input. Ultra low current requirements ensure cost-effective power distribution.

A single RS-485 communication interface port used for all network communication functions and interconnection to other modules.

* The Total Combined Current refers to the current that will be drawn from the external power supply to supply the module and any devices connected to the module's outputs. The reader voltage outputs are directly connected via electronic fuses to the N+ N- input terminals, and the maximum current is governed by the trip level of these fuses.

** Wiegand and RS-485 readers are NOT supported on this module and cannot be connected. To connect a Wiegand or RS-485 reader, use the reader ports on the Protege Controller and/or Reader Expander modules.
