Elevator Control
Floor Select Elevator Control
WinDSX fully supports Floor Select
Elevator Control and is capable of providing full elevator security. There are
two ways the WinDSX System can secure the Elevator.
The simplest method is to
disable the Car-Call Buttons on the common level or ground floor so that the
Elevator cannot be accessed until a valid card is used that enables the
car-call button. The upper or secured floors have free access to the elevators.
This requires just one reader and one relay output for each car-call button on
the floors that need to be individually secured.
The next method is to disable
all or particular Floor Select Buttons in each Cab. A reader is placed in those
cabs and presenting a valid card enables the Floor Select Buttons the user is
authorized for. This restricts all passengers to the floors that their access
code allows.
The typical system utilizes a
card reader in each elevator cab. The DSX System can be configured and
programmed to automatically secure and unsecure any
or all Floor Select Buttons in a cab individually, by time and day. Once a
Floor Select Button is secure, it requires the passenger to use their access
code or card at the reader in the cab before the select button will operate and
light when pressed.
The passenger's access code
determines which Floor Select Buttons are to be enabled for them to press. This
restricts the passenger from selecting buttons that correspond to floors they
are not authorized for.
If the elevator system is so
equipped, it is possible to receive a contact closure from the elevator
equipment to indicate and record which Floor Select Button is pressed. The
Outputs from the elevator equipment connect to one of the inputs on the DSX
panel to record which Floor Select Button the user pressed and to reset any
additional buttons that may have been enabled by the user's access code. This
keeps a tag-along from pressing a Floor Select Button that someone else's code
enabled. Floor Select Monitoring is facilitated by assigning the inputs to a
reader as shown below. This enables the Floor Select Elevator Reports in
History to show who pressed what Floor Select Button in a secure cab.
Car Call Monitoring
Car Call Buttons can also be
enabled and disabled by time and day and enabled by a user at a reader or
keypad in close proximity to the elevator on all restricted floors. Any
combination of car call and floor select restrictions may be designed and
implemented to meet the specific access needs of the user. With the flexibility
that code linking gives the System, each user's access code can enable
different floors and devices, depending on where, or in which cab, time of day
and day of week, the code is used. Floor select elevator control can always be
overridden at the PC.
Floor Select and Car Call
Buttons are secured by the Time Zones assigned to the DSX outputs they are
interconnected with. Up to four Time Zones can be assigned to each output. This
provides up to four secure periods per day for each button. This also allows
some floors to secure at different times than others, which is especially
useful in multi-tenant buildings. Some floors such as the ground floor do not
always need to be secured. Typically there is at least one floor select button
per cab that everyone has access to.
Linking Levels are used to
determine cardholder access to the Floor Select and/or Car Call Buttons. The
Access Level still determines which reader or keypads and at what days and
times the cardholders card will be granted access.
Once the cardholder is granted access, their Linking Level determines which
Floor Select and /or Car Call Buttons will be enabled for the user to press.
Linking Levels are managed
through the WinDSX software with a simple but
flexible approach. Every output is placed in a Linking Group by itself and
given a name such as “East Elevator Cab - Floor 2” “…Floor 3” and so on. When
defining a Linking Level using the WinDSX Linking
Level Manager, shown below, first select the reader or keypad the card holder
would be using and then select each Linking Group (Floor Select Button) to be
activated (enabled) when their code is used at that reader. The Linking Groups
selected are those that correspond to the Floor Selection and/or Car Call
Buttons this Cardholder should have access to and permission to push. Then
within the same Linking Level definition, select the next reader this linking
level should work at, such as the next elevator cab, followed by all of the linking
groups that should be activated from an access granted at that reader.
Elevator Control Output Linking Level Manager
Each Output in the Linking Group
has a Time Zone that determines what times and days the output will activate
when linked to. This provides a means to give different cardholders or even the
same card holder different windows of access, (defined by time and day), for
each Floor Select Button.
The following describes the materials needed for Elevator Control with
the DSX System:
One DSX-1042 /1022 Controller
for every two readers required. The DSX-1020 Controller provides 1 reader and
is efficient when the controller is located on the elevator cab instead of the
control or equipment room. Also needed to complete the interface is one relay
output for every Floor Select and Car Call Button to be secured. Use any of the
following or combinations thereof to achieve the correct number of outputs and
readers.
DSX-1042 Intelligent Controller (2 relays) (2 readers)
DSX-1022 Intelligent Controller (4 relays) (2 readers)
DSX-1020 Intelligent Controller (2 relay) (1 reader)
DSX-OX4 Output Extender (4 relays)
DSX-1043 Output Controller (16 relays)
The DSX-OX4 and the DSX-1043 Output
Extenders can be connected to DSX-1042, and DSX-1022 Controllers. Only one
extender per panel is allowed. Readers attached to the DSX-1042 and 1022
Controllers can activate relays on any controller or output extender in the
system. This operation is indicative of the Global Code-to-Linking Logic
feature available with the WinDSX System.
Location Partitioning for Elevator Control
Floor Select Elevator Control should
be partitioned into a Location separate from the door controllers. In a large
system with high traffic Floor Select Control and Monitoring should be grouped
so that each of the risers – Low, Mid, and High should
each be a separate location as well as any parking structures. Designing the
system in such a manner allows for orderly additions and upgrades.
