Notes
Scenario 1 — Hollow metal entrance door only
Your facility has two metal entrance/exit doors. You wish to
allow employees and the public full access during business
hours (from Monday through Friday 8:00 am to 6:00 pm).
Both doors will be programmed with an unlock/relock sched
-
ule to make sure the doors are automatically unlocked during
these hours. This unlock/relock schedule will be set to work
with a "First Card" mode, meaning the doors will not unlock
(via the schedule) until a token is presented from a valid card-
holder. Outside of those specified hours and on weekends,
only employees should have access to the entrance/exit
doors. The definition of who needs access to the main
entrance/exit doors only needs to be updated when new
employees arrive or employees part with the company. Your
site could have magnetic stripe locks, dual-validation or prox-
imity type locks.
You will need NT500 locks and the NT500 System software to
set up this type of access system. To set up this access system
the use of hardwired door controllers (AC512IPB or AC512B)
is not required. Definition of access for the entrance/exit
doors during business hours and on weekends can be
achieved through use of time mode profiles, door mode pro-
files, and access groups. Once you establish the appropriate
profile relationships in the software, this information can be
downloaded to the lock hardware at each door via a PDA
using the NT500 Transport software or via a laptop computer.
New employees can be issued cards for access as necessary
and this information can also be updated via PDA using the
NT500 Transport software or laptop.
Scenario 2 — Glass/aluminum entrance doors with
overhead door and computer door
Your facility has two glass/aluminum entrance/exit doors that
you wish to allow full access to the public and employees
from Monday through Friday 8:00 am to 6:00 pm. Both doors
will be programmed with an unlock/relock schedule to make
sure the doors are automatically unlocked during these
hours. This unlock/relock schedule will be set to work with a
"First Card" in mode, meaning the schedule will not go into
place until a token is presented from a valid cardholder. Out-
side of those specified hours and on weekends, only employ-
ees should have access to the entrance/exit doors. The
