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:
1.6.2.1
One Set of EFC301F (One Reader) – The Basic Door Entry Control
The most basic configuration involves one EFC301F (cont reader) and an electric
strike. In this configuration, a person presents a card to the reader, and is either granted
or denied access. The electric strike 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.
1.6.2.2
One Set of EFC301F (One Reader) + One Door Open Button – Control of Exit
Adding a door open button to the above scenario allows the system to control when to
allow people to exit through a door. The door open button equipment includes a
button which has to be pressed when a card holder exits, or a door sensor. The
equipment should be arranged on the secure side of the door.
