Questions & Answers
- Just a few of the most frequently asked questions. As
featured in the June 2007 Issue of Security Products...
Q: You
have recently introduced the Fault Tolerant (FT™) Controller.
What is this product and how will it improve access control,
alarm monitoring and output control systems?
A:
The Fault Tolerant controllers are the next generation of controllers, designed
to greatly improve system integrity and reliability. Our definition
of integrity is to provide an “online” security network
without any system degradation, even during the loss of communication,
hardware or firmware failure.
Q: How
is it possible to increase the reliability and the responsiveness
of security systems and networks using this product?
A:
We’ve developed a system that automatically enables itself
to be dynamically reconfigured, eliminating “failed” components
from the system. If there is a loss of primary communications, we provide
an optional communication path to “reconnect” back to the
host and remaining controllers. This self-healing technique is called “Real-time
Dynamic Network Architecture” (RDNA). The alternate
communication path can be “land line” or wireless, which
ever is best. Upon a hardware or firmware failure, current controllers
just fail. Whereas PCSC FT
controllers provide 100% backup operations if one should fail, another
simply takes over its duties. As long as there is at least
one functioning FT controller the system will operate without any security
degradation.
Q: What
are the main enhancements that make the Fault Tolerant system
work so well?
A:
The FT system utilizes the capabilities of 32 bit CPU and Ethernet
topology to provide a higher level of computing and communication integrity.
We incorporated a self-healing architecture allowing automatic
reconfiguration upon communication or hardware failure.
Q: Why
did PCSC develop a new “controller" architecture?
A:
There have been no new innovations within the Access Control industry
in a long time. The controllers have become faster, include the latest
communication techniques and incorporate the use of many card technologies
but essentially today’s controllers function like they did over
20 years ago. During our design process, we wanted to develop something
that was truly innovative. We wanted to design features for the “Next
Generation” of controllers to be useful for integrators as well
as end users. Our design goals were to provide high “Reliability” and
the most “Flexible” system configuration architecture to
meet today’s industry demands. We wanted to develop a system
that created the least amount of impact to the end user during a failure.
The design that best fit our goals was the “Fault Tolerant
Architecture” for
access control and alarm monitoring. “Fault Tolerant” architecture
is not new to the PC world but is not available in access controllers,
until now.
Q: What
makes this, the “Next Generation” of controllers?
A:
PCSC’s “Fault Tolerant” (FT) series provides the
next logical evolution in controller development. The FT architecture
provides a self healing architecture for communications and controller
hardware failures. The FT architecture provides full security during
primary communications failure or hardware failure. We call the automatic
self healing process, “Real-time Dynamic Network Architecture” or
RDNA. During a “failure”, the system will automatically
reconfigure its network and continue to process access decisions, alarm
and other transactional information to and from the host system, LiNC-NET.
The System provides Primary, Secondary, Tertiary or even Quandary communication
ports for communication backup. You would have to loose all 4 communication
ports before you had a “communication failure”. We offer
a variety of communications topologies like LAN, ZigBee wireless, WiFi
and PoE. Not only is the communication redundant, the controllers operate
in a redundant mode, utilizing Peer to Peer communications to maintain
the status of the network and database. If one MC fails for any reason,
its duties are automatically transferred to another MC. If the secondary
MC fails, another MC will automatically cut over to take over the failed
controllers duties. As long as there is at least one operational MC,
the system will continue to offer 100% security!
