The Telephone Line Drive Module (TLD-530) is
used to interface two (2) dedicated telephone line
circuits to the TLK-530 module. The TLD-530 line
driver module converts the RS-485 signals
received from the TLK-530 network interface
module to signals capable of being transmitted
over the telephone line circuits.One TLK-530
supports two channels so only one module is
required per controller for both single path and
redundant path star connections. The interface
allows for field configured baud rates and
supports distances of up 3,000 meters. Up to two
units can be fitted into a TLO/TLD Housing

ThornNet provides a true peer to peer
communications interface for up to 62, MINERVA
8, MINERVA 16E or MINERVA 80 fire controllers in
any combination and the ThornGraph, graphical
user interface. The units can be inter-connected
into a large network without the need for a host or
master controller. ThornNet is based upon a
combination of hardware and software that allows
MINERVA fire controllers (Nodes) to be linked
together. The ThornNet supports up to 61,380
analogue/addressable points, 4,960 zones and
over 7,000 digital I/0 points. The network co-
ordinates and distributes alarm annunciation and
supervises system operation. When connected to
the network, each MINERVA controller maintains
its full stand-alone features, functions and
capabilities.
Features
• LPCB approved
• A peer to peer network that does not use a
host or master controller.
• 62 nodes, 61,380 points, 4,960 zone capacity.
• Virtual Front Panel (VFP) enables an operator
to interrogate and control any MINERVA
controller from the keypad/display of any other
MINERVA controller.
• Bi-directional signalling.
• Open/short circuit isolation.
• Open/short circuit location.
• Events originating at any MINERVA controller
can be used as an input to event/action
processing of other panels to co-ordinate and
distribute systems control.
• System can be configured in the field using
Consys software.
• Failure of one node does not affect any other
node or communications between nodes. In
the event of multiple failures, nodes will
automatically re-generate into independent
fully functional networks.
• Automatic network re-configuration when a
previously failed node is restored to the
network.
• Up to 3,000 meters between nodes with
twisted/shielded cable.
• System will operate on standard 2 core MICC.
• MINERVA controllers may be grouped into
sub-nets where each panel is programmed to
inter-act only with other selected controllers.
• Plug-in module (TLK-530) easily connects a
MINERVA fire controller to the network.
• Data is re-generated at each MINERVA
controller and is sent out over the ThornNet as
new clean data. All degradation in received
data due to noise on a line, line attenuation, or
phase shifting is eliminated when the data is
re-generated.
• The ThornNet uses a token-passing, non
collision communication protocol for data
transmission.
• "Network zones" and "sectors" allow the
network controllers to be configured as a
single "seamless" system.
• ThornGraph, a P.C. based graphical user
interface, connects directly on to the network.
• ThornNet supports combinations of MICC,
twisted/shielded pair cabling, fibre optic
cabling, and dedicated telephone line.
• Multiple communication topologies bus or
ring.
The MINERVA ThornNet communications network
is a collection of network interface modules and
peripheral equipment that together form a
network.

The Fibre Optics Module (TLO-530) is used to
interface one fibre optic channel to the TLK-530
module. The TLO - 530 fibre optic interface
module converts RS-485 digital data current
pulses from the TLK-530 network interface
module to light pulses. The light pulses are then
carried over fibre optic cabling to another TLO-
530 where the pulses are converted back to RS-
485 digital data current pulses. Two TLK-530
modules are required per panel for redundant
path star connections and when using fibre optics
in both directions of ring and bus connections.
Two (2) type 62.5/125 fibres between controllers
(4 fibres when using redundant path star
connections) allow the interface to transmit
signals at 38.4 Kbs at distances as high as 4,000
meters between controllers.
Up to two units can be fitted into a TLO/TLD
Housing which has a chassis plate to
accommodate the units.

The key hardware component that makes the
network possible is the TLK-530 module. The TLK-
530 provides the electrical/mechanical means to
connect the components of the network to local
and remote network signalling circuits. Installation
of the TLK-530 is simplified with an edge
connector that plugs onto the main processor
board of the MINERVA controller. The TLK-530
provides RS-485 communications over a twisted
shielded pair as a standard configuration. The
distance between controllers can reach 3,000
meters at a speed of 38.4 Kbs using 18AWG
twisted shielded cable.
Fits within the MINERVA housing.
