ProtegeGX DIN Rail Single Door System Controller


The Protege GX DIN Rail Single Door Controller is the central processing unit responsible for the control of security, access control and building automation in the Protege GX system. It communicates with all system modules, stores all configuration and transaction information, processes all system communication, and reports alarms and system activity to a monitoring station or remote computer.

Key Features:

Integrated Access Control

Providing a highly sophisticated access control solution with large user capacity and extensive features:

  • Utilize multiple access levels to manage users over scheduled periods and time zones
  • Assign door groups, menu groups, area groups, floor groups and elevator groups to an access level for flexible user management. Each user can have multiple groups in multiple access levels
  • Monitor and control users' area status throughout the entire system with hard and soft anti-passback configuration options
  • Multiple card presentation options allows the use of access control cards, tags or other credentials to arm and disarm areas associated with doors
  • Count users entering an area and arm the area when the count reaches a terminal number or deny access to users based on a maximum user count

Connectivity and System Expansion

Extending the Protege System with onboard local inputs and outputs allows convenient cost effective expansion without the increased cost of modules for simple system functions:

  • 2 monitored onboard inputs, each of which can be programmed for EOL (End Of Line), dual EOL, or direct contact
  • 1 high current Form C relays onboard
  • 1 integrated RS-485 reader ports
  • RS-485 connections support configuration for OSDP protocol
  • System expansion is achieved seamlessly by connecting additional expander modules

Output Follows Input Programming

The Protege GX system's advanced programming features provide endless opportunities for customized automation. Output follows input programming allows any output or output group in the system to be intelligently controlled by any input or input type. This has a wide variety of applications: from turning on lights and climate control when motion is detected, to unlocking a specific door with a key switch, or auto arming an area after a period of inactivity.

Programmable Functions

Programmable functions are special applications that implement logical control of outputs, doors, areas, and other devices:

  • Perform actions when a particular event or operation occurs, such as setting the room temperature based on the number of people in an area, adjusting internal lighting levels based on a sensor reading, or unlocking doors in the event of a fire alarm
  • Process logic functions to allow complex equations to be evaluated using internal memory data values and output status
  • Control of doors, areas, elevators and outputs can be easily programmed and managed


The Protege controller offers integration with a wide range of third party systems:

  • Link the Protege system with intelligent locking solutions through comprehensive world class solution partners including Salto, Aperio, and Cencon
  • High level interface for control of modern elevator systems
  • Integrated biometric identification systems provide superior user identification options
  • Other third party integrations such as building and lighting control systems

Integrated Arming/Disarming

Featuring advanced integration of arming and disarming solutions for control of hundreds of alarm areas:

  • Deny access to a user based on the status of the area and the ability for the user to control the area they are entering, in turn reducing false alarms
  • Implement vault control areas to manage time delayed access and unlocking of vault areas in banking facilities without the need for additional hardware control devices
  • Control access to a keypad using a card and PIN function, or allow card presentation to automatically log the user in at the associated keypad
  • Disarm an area associated with an elevator floor on access, or prevent the user from gaining access to the floor based on the area status associated with the floor
  • Arm large numbers of areas using area groups


RS-485 communication interface and a 10/100 Ethernet communications port provide a complete solution for system expansion, offsite monitoring, system communication and integration.

Multifunction Reporting Services

The controller incorporates a host of offsite reporting options:

  • Implement IP based reporting using onboard Ethernet and the ArmorIP protocol
  • Report alarms using Contact ID, SIA Level 2
  • Communicate with third party applications using ASCII or HEX directly from the controller

Ethernet 10/100 Connection

Onboard Ethernet communication allowing direct connection from a local PC or interconnection to an existing LAN/WAN:

  • Directly connect the Protege system across a LAN or WAN interface for high speed upload and download
  • IP reporting functionality using the ArmorIP protocol, Contact ID over IP, SIA over IP and full text reporting methods
  • Full 10/100 compliant network interface allows connection of the controller to all networks at the maximum capable signaling rate

Flexible Reader Support

Provides 1 reader ports, allowing the connection of up to 2 readers controlling 1 door.

RS-485 connections are configurable for OSDP protocol, offering additional security and adding scalability, flexibility and ease of implementation.*

* The ICT implementation of OSDP conforms to a subset of the OSDP functionality. For specifications and reader configuration, refer to AN-254 Configuring OSDP Readers.

Upgradable Firmware

Firmware can be upgraded directly from the Protege GX software.

*The Total Combined Current refers to the current that will be drawn from the external power supply to supply the Controller and any devices connected to the Controller's outputs. The Auxiliary outputs and Bell output 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.
