The Europlex 3GS Integrated System
is based on it’s Intruder Alarm capabilities and structure. A number of
components make up the complete intruder alarm system, however the Control Panel
Should be considered as the HUB of any system. Two Control Panel is available in
two sizes. The Slim-Line controller comes complete with a 3 Amp power supply
unit and the enclosure is capable of accommodating 2 no. 17 Ah batteries. The
Standard Controller accommodates 2 no. 24 Ah batteries and comes complete with
an 8 Amp power supply unit. Both controllers House the same Control PCB and
provide the same software and hardware facilities.
As standard, the controller
provides for an 32 area Integrated Software and, through it’s ring-net
infrastructure is able to support 200 alarm inputs and provide 255 relay
outputs, where all inputs and outputs are addressable.
Three communication ports are
available for use with Modems, Pagers, Network interfaces and PC communication,
each independently operable. Additionally the controller provides for 8 no. on
board alarm inputs and provides for 4 no. relay outputs.
The system is expanded utilising
NODES. A node is an intelligent addressable device which enables expansion and
interaction with the 3GS controller. Four specific types of nodes are utilised
to expand the 3GS intruder alarm system: -
The I/O Node provides for 8 no.
Addressable Alarm Inputs and Provides 1 no. programmable Relay Outputs.
The Output Node provides 6 no.
programmable Relay Outputs.
The Remote Keypad Node Provides a
20 button, menu driven display interface to the alarm system as well as
providing for 2 no. Addressable Alarm Inputs and Provides 1 no.
programmable Relay Outputs.
The Encryption Node provides the
same features as the I/O Node, but with the facility to enhance the level of
security by utilizing encoded SMART PCB interfaces which may be located within
the detection device.
Up to 99 no. Nodes may networked
with the 3GS controller utilizing a fault tolerant Ring-net cable. In essence,
the system requires a loop of cable that commences and terminates at the control
panel. 4 core cables required for this loop, where 2 no. of the cores are used
for Data and 2 no. of the cores are used for DC power distribution.
Because 3GS Nodes are
self-addressing using Serial numbers instead of Programmable
switches, all or some of the inputs on each node may be used, without loss or
waste of the overall capability of 200 no. Inputs per control panel.
3GS utilises dual end of line
resistance for protection of each circuit, based on 2K2 resistance. In Addition
to the nodes previously highlighted, Europlex also are committed to support
previous sold products wherever possible. For this reason Europlex Technologies
Designed The LEM Node which enabled Aplex systems to be upgraded to the 3GS
System, hence allowing the user to take advantage of the new capabilities
offered by the 3GS.
Where a user is currently securing
his premises by and APLEX 16, 30 or 100 system, The Aplex control panel can be
replaced with the LEM Node. This device will be located on the 3GS Ring-net and
allow use of the existing APLEX cable infrastructure as well as all LEM’s
currently on line. It should be noted that specific guide-lines should be
followed and these are highlighted later on within this section.
Dependant on the amount of circuits
to be utilised by the system and the relevant current consumption by the nodes
and the detection devices, it may be necessary to boost the amount of power
available to be distributed around the Ring. For this reason Europlex provide a
range of intelligent monitored Power Supply Units for use with the 3GS system.
The Europlex 3GS System is
manufactured and designed to be compliant with current British Standards, BS4737
and BS 7042 and is suitable for installation within the UK by NACOSS and
similar organization recognized installers. Where Police response or regularity
restriction are not required, 3GS will provide a high security intruder alarm
system with remote or on site monitoring.
3GS is a fully modular system and
should other disciplines require to be added, at the time of installation or in
the future this is accommodated within the Control Panel based software.
When to use the LEM node!
The LEM node should be considered
as a 100 input, 50 Output node and is used to
replace the Aplex panel, whilst utilizing all cabling, LEMs, and resistors on
the existing
system. The node has an onboard PSU, and connects at any location on the 3GS
ring-
net.
It should be noted that Aplex
Keypads are not included in the above equation. This is
because the RKD node on the 3GS is an actual node and hence must sit directly on
the
ring-net.
When to use the LEM Node
To update from an Aplex system to a
3GS System, at minimal cost, utilising existing
cables and LEMs.
To increase the amount of Zones and
outputs provided by a fully laden Aplex.
To add additional features provided
by the 3GS, but not by the existing Aplex, such
as access control, radio PA and on-site paging.
When cables are out of reach and
economic factors prohibit the installation of new
cable infrastructure.
When NOT to use the LEM Node
If cables are in a poor condition
and distances exceed 800 meters in total.
If the Aplex installation is
unknown and locations of LEMs and cables are unclear.
If cable integrity is of an issue
and the fault tolerant ring-net attributes are required
for the whole system.
If only a few zones are being used,
it would be more economical to utilise 3GS
nodes than the LEM node for upgrade.
