Smartec ST-NC440B Network Controller

The Smartec ST-NC440B network controller is designed for four one-way or two two-way access points, four readers with Wiegand 26 and Wiegand 34 interfaces. Compatible with most codebase panels. Supports identification by card, card and code, card or code.

Specifications:

• The number of users is 30,000.
• The number of events is 100,000.
• The number of time zones is 256.
• The number of access levels is 256.

The controller is based on a 32-bit 400 MHz processor with Embedded Linux OS. It works under Timex control. Supports TCP/IP or RS-485 connection, the possibility of redundant communication.

Functionality:

• Control of four locks with NO and NC contacts.
• Unblocking on the first card.
• Access via multiple cards (the N-person rule).
• Support for the prohibition of double—pass - Antipassback.
• Pass code support under duress.
• Gateway mode (with reed switch connected).
• System freeze protection is a hardware watchdog timer.

Without a long-term connection to the server, the controller works offline while maintaining all functionality. It is equipped with 256 MB Flash memory and 32 MB RAM.

To increase security, the controller includes hardware protection measures against:

• Reverse polarity of the power supply.
• Overcurrent, voltage overload.
• Voltage overload across all communication ports.
• Voltage overload across all inputs/outputs.

The ST-NC440B is equipped with DIP switches for switching on the matching resistor and setting the device address in the RS-485 bus. It is equipped with indicators of the status of the lock relay, receiving and transmitting data via the RS-485 bus, the status of connection and data exchange via TCP/IP, and receiving data via the Wiegand interface.

Other ports of the controller:

• Inputs for connecting power to the controller and locks.
• Four lock relays.
• Four reed switch connection inputs.
• Four inputs for connecting exit buttons.
• Four additional inputs for connecting security sensors (smoke, gas, etc.) and detectors.
• Four additional outputs (depending on the software) for connecting alarm actuators, doorbell, etc.

The controller is supplied in a box case. The operating temperature range is 0 ° C... +55 ° C. Power supply — DC 12 V. Current consumption is up to 300 mA (excluding readers). The size of the controller is 218×106 mm, the box is 345×275×70 mm.
