BIU 130 Bus Interface Unit

The Naztec Model BIU 130 Bus Interface Unit links the TS-2 Controller Unit to the Cabinet I/O. It is responsible for controlling load switches, providing dimming, receiving and isolating pedestrian calls, analyzing detector faults, time-stamping detector calls, and providing detector resets. By design, the BIU is free of operator contorls. The BIU performs its I/O functions based upon a pre-wired card rack address.
