SYSTEM DESCRIPTION
A. The KellyTube Cash Secure Pneumatic Tube System shall
be 2.25", 3", 4", 6", 8" and 4"x7" oval (as required). Aluminum
single tube vacuum/pressure type, as manufactured by Kelly
Systems, Inc. of Chicago, IL and shall provide dedicated
service between designated stations. Stations shall be located
in the following areas as shown on the drawings, with service
as follows:
VAULT/CASH ROOM TO AND FROM
B. Carrier transmission is accomplished by a central power
unit which shifts between vacuum and pressure operating
modes. The central power unit shall be free-standing type
which is located in the Vault/Cash Room or can also be located
remote from the central station.
C. The System is designed for operation only while a carrier
is in transit between stations, and when carriers have been
queued for dispatch, all controlled by the PC computer.
The System is designed to transport one carrier per operating
cycle at an average speed of 25 feet per second.
D. To dispatch a Carrier from a Sub Station, open the Station
Door and place the Carrier on the Station Pad. Depress the
Send Pushbutton, then close and latch the Station Door.
Vacuum will then propel the carrier to the Central Vault
Station, after which the system will automatically turn
off. If the System is in use when a dispatch is desired,
the Cashier may still initiate a transaction as described
above, and the System Computer will automatically dispatch
the Carrier when the current transaction has completed.
E.
To dispatch a Carrier from the Central Vault/Cash Station,
open the Vault/Cash Station Door and place the Carrier on
the Station Pad. Close and latch the terminal door, select
the desired Sub Station from the destination menu on the
Computer Monitor using the arrow keys, then press Enter.
The Power Unit will dispatch the Carrier on pressure to
the Sub Station and will then automatically turn off. The
Real-Time details of the transaction are displayed on the
Computer Monitor and are fully viewable by Vault Personnel
during the transaction.
F. All Sub Stations are down-delivery full-access type,
complete with reinforced polycarbonate door. The Doors are
hinged and reinforced with a metal frame. All Sub Stations
are key lockable and have an integral Send Pushbutton and
Indicator Lights. Sub Stations can be wall, floor or counter
mounted, and must maintain a clean appearance throughout.
G. The Kelly Systems Cash Secure Pneumatic Tube System is
fully expandable with the addition of Diverters and Stations
without requiring modification or replacement of existing
equipment or control software.
1.3 SYSTEM SOFTWARE DESIGN
A.
The Control Software and System Features were designed based
on the specific requirements for secure cash handling and
monitoring. To this end, the System was specifically designed
with an easy to use computer with a full color 15 inch monitor
and keyboard. This provides a very understandable, menu
driven operator interface, as well as, allowing for easy
programming changes as needed or requested.
B.
With a full 15 inch display Monitor in plain English, the
display incorporates user hints of how to use the system,
shows real time progress of transactions, and provides audible
and bright color visual displays of system and user errors
with instructions on how to correct these faults. (If the
customer chooses to provide phone or internet connection
to the P.C. then remote diagnostics and maintenance are
possible.)
C. A large Usage History with time and date stamp and transaction
details is incorporated in the Software. Due to the sometimes
critical nature of transaction details, the Software automatically
stores and maintains full information for the last 10,000
transactions. This Transaction History can be displayable
on the screen or output to a printer and can be set to print
any selectable Transaction range.
D. The System will queue transaction requests from all Sub
Stations. When the System is busy with a current transaction,
a Sub Station or multiple Sub Stations may still initiate
their own transactions which the Software will monitor.
As a transaction completes, the Software will automatically
begin the next transaction, initiating each queue in the
sequence in which they were entered. Due to the importance
of Vault/Cash Room transactions, the Vault/Cash Room may
interrupt the queued sequence with a priority dispatch.
When the Vault/Cash transaction is completed, the queued
Carrier dispatches automatically resume.
E. A clock programmable System Purge is supplied to send
any Carriers
inadvertently left in Sub Stations at closing time to the
Vault/Cash Room Safe. Vault/Cash Room personnel can set
the time they want this function performed (e.g. 1:00 AM)
or may disable this function at their discretion.
F. The System Software also provides for a quick transition
from the Day Mode to the Night Mode. When Vault/Cash Room
personnel are present, the System is normally in a Day Mode
which allows for Sending Carriers to the Sub Stations and
Recieving carriers in the accessible Vault Station. When
Vault Room personnel are not present, the System can be
switched to protective Night Mode with the press of a button
on the Keyboard. Carriers from the Sub Stations will then
deliver into a locked Vault. A Password is then required
to switch back to Day Mode which must be entered on the
keyboard. This keeps unauthorized personnel from switching
the Sytem from a protected Night Mode to Day Mode. A clock
programmable Night Vault/Cash mode is incorporated in the
Software to automatically switch the System to Night Mode
at a predetermined time, in the event the last Vault/Casy
personnel for the day forgets to do so.
G. A Carrier Present feature is included so that the Vault/Cash
Personnel can easily see which Sub Stations have carriers
present in them. This is helpful when a money till is called
for, but not promptly removed from the Sub Station. The
Vault/Cash personnel can see this and make a judgement as
to whether to retreive this back to the Vault/Cash Room.
The Retrieve function is controlled at the Vault/Cash Room
so calling out to the Sub Station is unnecessary. This feature
is also useful if the Vault/Cash innadvertently sends a
carrier to the wrong Sub Station.
H. All Send/Receive Stations are equipped with non-contact
highly reliable optical sensors. Thru beam infrared optics
are highly reliable eliminating problems associated with
mechanical contact switches.
I.
All Send/Receive Stations are equipped with Key-Lockable
Doors. This, together with the high strength polycarbonate
doors allow visual recognition of a carriers presence, while
affording strong theft protection.
J.
Sub Stations can easily be disabled through the Software
so that carriers can not be inadvertently or deliberately
sent to inactive Sub Stations. Thru the menu driven configuration,
the Vault/Cash Room can easily turn off a station that is
not being used. This function is password protected.
K. The Software provides Purging of Stations or the entire
System to check for Carriers. The System Maintenance Menu
allows the Vault/Cash Room to Purge any Station individually,
or all Stations sequentially. Either type of Purge can be
cancelled at anytime. Station Purges can be done in either
vacuum or pressure modes.
L. System diagnostics and maintenance are provided to insure
all System equipment is operating properly. The System Maintenance
Menu allows Vault/Cash personnel to position and operate
Diverters, Blower, Air Shifter and Vault Shifter directly
from the keyboard. These maintenance features are invaluable
in serving maintenance needs over the phone. Diverters can
also be moved with vacuum applied to clear Carriers that
may get caught in Diverters. Again, these features are operated
from the keyboard in the Vault/Cash Room.
a. All electrical components are connected with industry
standard RJ45 networking for quick and easy connection of
components. The data runs on U.S.standard 485 protocol.
The System uses distributed 24 volt power so there is no
need for 120 volt power supplied anywhere except in the
Vault/Cash Room.
N. The System Software keeps track of transaction timing
cycles. If a carrier is not delivered to a Sub Station or
the Vault/Cash Station in the requisite time, the System
will automatically apply more time and begin looking for
the Carrier and any System errors. If the Carrier still
does not reach its destination, an error alert will be displayed
and an audible alarm will sound in the Vault/Cash Room.
An error specific message will be displayed with error correction
options for clearing the error. These messages are all displayed
in clear, easy to understand English.
1.4 MATERIALS AND INSTALLATION
