access controller

Description

It supports 6,**0 card holders, with RS**5 interface, can be networked with *9 controllers, and can be connected with W*6 and RS**5 readers, with the distance of transmission of 1KM. NT2 (two-door controller) and NT4 (four-door controller). With **5 bus, *9 sets of NT2 or NT4 controllers can be connected into a control network to manage **6 door areas at most, with **2 card readers. The system adopts advanced modular architecture, with each control working independently, and capacity can be expanded easily. Selected modules can integrate the functions of attendance, charge, parking lot management, lift control, and patrol, etc., compatible with multiple types of front-end input devices. The board adopts SMD mounting technology, high precision components, mature and reasonable circuit design and reduced separate devices, and uses large-scale integrated circuit, thus guarantees the safety and stability of the whole system. Each controller supports up to 6,**0 card holders. It is connected with a password keypad card reader, which provides excellent safety for entering and existing control, and has the threefold anti-passback function, which makes the door control management more scientific and perfect.
