System Design Information

Below are descriptions and examples of properly planned and designed systems. To the right are supporting download links for specifications. 

System Layout and Design

One aspect of Designing a System is the initial footprint. How the system is started can affect how efficiently it grows in a logical and organized manner. These brief overviews will try to show several examples of initial application footprints based on system size and growth expectations.

Small to Medium System with moderate growth.
In this application there is typically 1 computer to start with. This one Host PC operates the entire system. In some cases this may increase to include one to three client PCs. There is typically one location to start with comprised of one master controller which operates the first two doors. As more secure doors are required additional controllers are simply added to the existing location. In some cases there may be a few more buildings that are added to the system. Each of these is added as a new location more than likely in the same location group sharing the existing card holders.

Large system such as Hospitals, College Campuses, or Large Facilities with major growth potential.
In this application there is a Comm Server PC for system communications, a SQL Server PC for the shared database, and one or more Client PCs for the actual users of the system such as security and database administrative personnel. Typically these applications start with 10 - 20 doors and grow to 3 - 400 doors or more easily. In these situations there should be a multiple location approach starting at the beginning of the system construction. There should be at least one location for the Parking Structures, one for the Elevators (if performing elevator control) and one for each architectural division of the property. This is typically determined by how the customer refers to their building; by floor or by wing or other. This allows for future growth to be efficient and simple. With this approach each location has major growth potential, quick response, distributed intelligence and operability, and certainly organizational efficiency. When designed in this manner it easy to find a door or alarm point amongst hundreds or thousands of others. Its easy to build and maintain access levels and perform other system support.

Widely disbursed system with Hundreds of buildings such as sub/relay stations or stores with few doors in each.
In this application there are many locations scattered around the country or state. Each location may have just a few doors. The emphasis is there are many locations and not so many doors in each location. In this situation instead of having hundreds or thousands of Locations we would deploy PC Master. PC Master would communicate with up to 63 different buildings and keep them all under one location. So there could be a separate PC Master for each region, district, county or state. All controllers in that area would all operate under one location through its respective PC Master. This keeps the system processing requirements distributed but organized.
