•Dual RACK DESPLEX interfaces will continue to use the “70” as the start
of the 9 digit account number. However, the second rack connected via a
separate Serial port will start all account numbers with “7A”. This is
important to note when you are adding text messages. Account “700104-
02” is not the same as “7A0104-01”
•User can also enter Zone 700702-01 (or 7A0702-01 for second rack
systems) when entering a zone specific message for the point being
monitored.
•The DESPLEX events can be routed to an Automation system via the
SYSTEM 3505/PRISM LX.
•The SYSTEM 3505/PRISM LX will display communications faults
between the DESPLEX racks and the Subscriber units.
•Just like the SCT product, the SYSTEM 3505/PRISM LX cannot advise if
a device is no longer connected if such disconnection occurred while the
SYSTEM 3505/PRISM LX was turned OFF, then turned ON when the
Subscriber or other parts of the system have been disconnected. This
feature can be incorporated into the product should the customer wish to
upgrade the overall capability of the DESPLEX/SYSTEM 3505/PRISM
LX communications.
•The SYSTEM 3505/PRISM LX must be equipped with sufficient MEM-
600 devices to accommodate all of the messages that the customer desires
to enter into the SYSTEM 3505/PRISM LX.
•The SYSTEM 3505/PRISM LX can accommodate the Two Man rule for
monitoring Subscriber units.
•A command mode is available which allows the user to interrogate the
DESPLEX from the SYSTEM 3505/PRISM LX for verification of various
conditions in the overall DESPLEX system. The command mode is an
option that needs to be added to the SYSTEM 3505/PRISM LX at
additional cost.
Two Man Rule
•The two man rule allows the SYSTEM 3505/PRISM LX provide a 45
second exit delay to any number of input devices at the Subscriber
location. This allows the user to Arm the subscriber unit, then exit the
facility via the Exit delayed zone(s) and the exit delay zone(s) will
arm after 45 seconds. While the event will be logged by the SYSTEM
3505/PRISM LX, it will Acknowledge itself and Not send the event to
the Automation system. However, if after the Exit delay expires, the
