2.1.2 Determine the Hardware and Location

Determinewhichhardwaretouseandwhereitwillbeinstalled.Thisisthemostcrucialstep

in the preparation stage. First, determine how many access points, or doors, need to be

managedbytheaccesscontrolsystem. Theseaccesspointswillcontrolthesecurityofthe

facility,  and can limit the entry and exit to and from any given area of the building. After

deciding which doors need to be controlled, the user must also determine the level of

security needed at each door. There are many ways to manage each door, using different

resources. These resources include, but are not limited to: proximity readers, mag strip

readers, relays, and request to exits. A few common door configurations are described

below:



 OneSetofEFC301–TheBasicDoorEntryControl

The most basic configuration involves one EFC301 and an electric strik e. In this

configuration, a person presentsa card to the reader, and is either granted or denie d

access.Theelectricstrik eunlocksifthesystemgrantsaccess.Anothervariationofthis

scenario involves setting the system up to monitor whether the door is open, which

allowsthesystemtoprotectagainstproppedopendoors,ordoorsbeingheldopenfor

toolong.
