Floor Tracking Message – Floor tracking messages, when the floor tracking option is
selected, are generated only for floors whose associated output is exclusively
enabled by the elevator access grant, i.e., it is not co-enabled by public access or by
direct output control. A floor tracking message is generated for each elevator input
that:
 Experiences a transition from the open into the closed state during the
elevator access time.
 Is in the closed state at the time a valid badge is presented.
The floor tracking messages includ
es the badge’s number and badge holder name of
the last person to present a valid badge at the reader, and the floor name of the
pressed button.
Override – Wh
en the reader terminal in the elevator cab is overridden, all of the
associated outputs relays are energized by the public access feature. This means, that
there will be no floor tracking messages generated. Except for local cardholder
override, all modes of reader override are applicable to elevator terminals, i.e.
override per timezone, per panel system override and per the “Unlock All Doors”
command from the server.
Executive Privilege –
Badges with executive privilege enable all floors of the
elevator per elevator access grant.
Performance Considerations
The more readers and input/output terminals are installed at a single CK721-A, the
longer the system response time gets. Also, care has to be taken not to exceed the
power supplies’ capabilities when all output relays are energized at once. The
theoretical limit per CK721-A is set to 16 elevators with 128 elevator buttons
combined. The practical limits are determined by the desired response times.
Cabinet Access Control
Cabinets are readers associated with a set of output points and an optional set of
input points. The field panel interfaces with a bank of cabinets using output points to
unlock cabinet doors, and input points to monitor the status of cabinet doors.
The panel may grant access to a cabinet by unlocking the corresponding door when a
badge is pres
ented at a reader installed in the cabinet definition.
The cabinet access control gives you the ability to assign cardholders the access to
various cabinets and doors in your
facility, through their access groups.
Cabinets are assigned doors and door groups, then
these doors and door groups are
included in access groups which are assigned to cardholders.
Cabinet readers cannot be overridden
by a Local Cardholder Override or a Timed
Override, and do not allow the Auxiliary Access input to grant access to any doors.
Also, panel card events cannot be used on cabinet readers.
