Protege DIN Rail
2 Door Reader Expander

Extending the Protege system with local inputs and outputs from the Reader Expander allows for a convenient, cost effective expansion and the added benefit of dual functionality on door monitoring inputs.

• 8 high security inputs can be used to perform system monitoring, alarm and automation functions. All 8 inputs have preassigned functions that are processed by the reader expander for door control. Each function can be enabled individually.
• 6 open collector outputs can be used within the system for the management of controllable devices such as relays, lighting and building automation.
• System expansion is achieved seamlessly by connecting additional expander modules
• Address configuration is achieved using the address programming feature of the Protege System Controller.

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.

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

Featuring advanced integration of arming and disarming solutions for control of hundreds of alarm areas, the module allows a user to arm and disarm an area from an input associated with a door:

• 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
• Repeated presentation of an access card can arm an area associated with the entry or exit direction of the door being accessed
• Arm large numbers of areas using area groups

Utilizing the latest flash technology and high performance communication mediums, the firmware can be updated via the Protege interface.

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