3GS?
The 3rd Generation System, 3GS, is based on a patented
high security, fault tolerant ringnet offering flexibility
beyond the boundaries of any existing security control
system or access control system. The 3GS is capable of
integrating with building management systems and video
and audio verification systems. This, coupled with its
high security and self-diagnostic features, makes it the
most advanced system of its kind.
Cable Problems Solved
The system architecture consists of interconnected
elements called nodes , distributed in a ring configuration.
These nodes let you access the system to connect inputs,
outputs, operator keypad/display units, and so on. Power
may also be distributed from nodes to the devices
connected locally. The current system supports up to 100
nodes and a controller.
The benefits of this topology and associated control
protocol are immense. They impart to the system both
cable fault tolerance and self diagnostics. For example, if
a network cable, wired for fault tolerance, is damaged in
any way (for example, cut, shorted, or grounded) the
user suffers no loss of functionality – all inputs are still
monitored, all inputs can still be controlled, and all
keypads are still functional.
In addition, the location of the fault is indicated by the
system – cable tracing to locate the problem is no longer
necessary. In fact, accidental ringnet cable damage need
not cause false alarms. Intermittent cable faults, the bane
of many an alarm installer, can be isolated and treated.
No longer do multiplex cables mean complicated
problems.
Superior Communications
The availability of three serial ports (one RS232 9 pin
type and two TTL) provides significantly greater
communication capabilities.
For example, a LAN, remote PC, and a printer can all be
connected simultaneously.
Note
The Europlex 3GS+, ED2000, Panelman,
and Network XII are all 3GS compatible.
Ease of Installation
All system nodes are automatically configured, each
being assigned an ID number in sequential order. This
significantly reduces the time spent programming a
system.
Each node on the system is also self diagnostic. Any node
can be easily found (even above ceiling tiles or in
cupboards) using the unique audio node locator system.
This ensures that you no longer need to follow wires in
order to locate boxes for maintenance purposes.
Once a node has been located, it can be interrogated
using the revolutionary Europlex wireless Hand Held
infrared Terminal (HHT). Without opening the node
enclosure, full diagnostic testing can be performed
including power voltage and current measurement, input
and output status and operation, Ringnet
communications status, and much more.
Most of the fault-finding process of opening boxes,
moving wires, metering, re-positioning of wires and re-
closing of boxes, and management of associated tamper
conditions can be eliminated.
These are only some of the unique advantages of 3GS. A
reduction in both installation and maintenance time
means cost savings for installation companies, quicker
response to customers and less disruption of their
business.
System Integration
3GS offers unique and comprehensive integration of
access control, wireless and cable alarm capability on
one hardware platform. 3GS offers multiple
communication possibilities via its three serial ports. For
example, radio paging, LAN or WAN connectivity,
remote servicing via modem, and so on.
