Overview
SA-1773 Central Processor

The Smart Access model SA-1773 Central Power Processor interfaces with model SA-1606 Door Units, model SA-1930 Input-Output devices and model SA-1936 Graphic Display Panels utilizing a two (2) wire multi-drop communication line. When interfaced, the system becomes a powerful Multiple Door access control system featuring distributed processing. Distributed processing, where immediate decisions about granting or denying access are made at the individual door, is superior to a centralized system where all decisions are made at the main CPU. Thus, degraded mode does not exist in the event of the CPU or link failure.

The model SA-1773 Central Power Processor can accommodate up to 64 devices on a two (2) wire communication line. Additional devices can be attached utilizing the SA-1920 Repeater. The Central Power Processor has a twelve (12) button numeric keypad, a Liquid Crystal Display (LCD), a high speed communication port and a parallel printer port. Programming of single doors, or blocks of doors is fast and easy thanks to the LCD prompts. With a printer connected, activity for all doors or selected doors may be logged as it occurs. The Central Processor can store transactions in its internal buffer, thus eliminating the possibility of lost messages even under heavy traffic conditions. Further, if the link with any of the connected devices on the two (2) wire communication line is broken, the central processor will advise the operator and when the device comes back online, handle all incoming message processing.
