Protege GX DIN Rail
System Controller (IP Only)


The central processing unit responsible for the control of security, access control and building automation in the Protege GX system. The controller 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.

  • 2 doors (4 readers)
  • 8 multi purpose inputs
  • 1 monitored bell output
  • 2 Form C relay outputs
  • 4 low current outputs


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

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:

  • 8 monitored onboard inputs, each of which can be programmed for EOL (End Of Line), dual EOL, or direct contact
  • 2 high current Form C relays onboard
  • 2 integrated reader ports, independently configurable for Wiegand or RS-485 operation
  • Bell/Siren output onboard with fully monitored operation
  • System expansion is achieved seamlessly by connecting additional expander modules

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

ICT controllers are cyber secure, supporting emerging cybersecurity requirements through advanced security features. 

With secure encrypted communication, resilience to outages, secure storage of security parameters and no universal default passwords, ICT controllers are inherently designed to protect devices, networks and data from unauthorized access.

Mandatory cybersecurity regulations on connected devices are defining requirements in terms of data & cryptography, logical security, system management and privacy protection. 

ICT controllers feature essential requirements of newly introduced standards and legislation aimed at regulating the Internet of Things

Equipped with a factory loaded HTTPS certificate, ensuring a secure encrypted web connection straight out of the box. The default certificate provides automatic TLS encryption of data transmissions, secure identity authentication, and message signing
to assure data integrity.

Provides 2 reader ports that can be independently configured for either Wiegand or RS-485 reader operation, allowing the connection of up to 4 readers controlling 2 doors.

Choose Wiegand readers for compatibility with all standard access control systems, or RS-485 for fast, secure communication.

RS-485 readers provide the added benefits of being easier and more cost effective to wire and deploy, and allow for direct integration with Protege systems, enabling you to make changes on the fly once readers are installed. RS-485 also allows for longer cable runs and offers a simpler firmware update process.

OSDP protocol configuration in RS-485 offers additional security and adds 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.

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

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 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

The controller incorporates a host of offsite reporting options:

  • Implement IP based reporting using onboard Ethernet and the ArmorIP protocol
  • For complete peace of mind, set up multi-channel reporting using a combination of local ethernet and 4G network (via the Protege DIN Rail Cellular Modem).
  • Communicate with third party applications using ASCII or HEX directly from the controller

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

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 expander and any devices connected to its outputs. The Auxiliary outputs are directly connected via thermal resettable fuses to the N+ N- input terminals, and the maximum current is governed by the trip level of these fuses. The Bell output is connected in the same way.

** Each reader port supports either Wiegand or RS-485 reader operation, but not both at the same time. If combining reader technologies, they must be connected on separate ports.
