2.1.1 Obtain a Floor Plan
Obtain a floor plan of the building in which the access control system is to be installed.
Obtaining a floor plan helps the installer determine what components need to be
installed, and where. It also is essential in determining the length of cable needed to
connect readers to the controller. A floor plan can be a blue print of the building, a
design, or simply a drawing of the facility. Any document showing the footprint of the
building can be used. The dimensions are important to note, especially when
determining cable lengths. A floor plan may be obtained from your local city hall.
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 NAV Controller+ One Reader – The Basic Door Entry Control
The most basic configuration involves one NAV controller, a 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.
•
One Set of NAV Controller+ 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.
