Smartec ST-NC240B Network Controller

The Smartec ST-NC240B network controller is designed to control two one-way or two two-way access points with identification by card, card and code, card or code. Supports the connection of four readers with the Wiegand 26 and Wiegand 34 interfaces. Compatible with most codebase panels.

Specifications:

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

The controller is built on a 32-bit 400 MHz processor, Embedded Linux OS. It works under Timex management. Supports communication redundancy, TCP/IP connection or RS-485 bus.

Functionality:

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

In offline mode, the controller works for a long time without connecting to the server. It is equipped with 32 MB RAM and 256 MB Flash memory.

To ensure increased security, the controller has hardware protection against:

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

The ST-NC240B is equipped with indicators for transmitting and receiving data over the RS-485 bus, the status of connection and data exchange over TCP/IP, data reception via the Wiegand interface, and the status of the lock relay. It is equipped with DIP switches for switching on the matching resistor and setting the device address in the RS-485 bus.

Other ports of the controller:

• Inputs for connecting power to the controller and locks.
• Two lock relays.
• Two inputs for connecting exit buttons.
• Two door position sensor inputs.
• Two additional inputs for connection of security sensors (fire, gas, smoke, etc.) and detectors.
• Two programmable additional outputs for connecting alarm actuating devices, doorbell, etc.

The controller is supplied in a box case. Operating temperatures are 0 ° C... +55 °C. Power supply — DC 12 V. Current consumption without readers is up to 300 mA. The size of the controller is 160×106 mm, the box is 345×275×70 mm.
