The Protectowire FiberSystem 8000 has been designed for use as a
linear heat detection system using state-of-the-art fiber optic sensing
technology. The system consists of Type PFS Fiber Optic Sensor
Cable and the PTS Controllers with related software. The PTS
Series Controllers can be configured for various alarm criteria and
can be connected to an approved fire alarm control panel using
relay inputs and outputs. The system is specifically designed for
high risk commercial and industrial hazards that demand high reliability and customized system features.
Protectowire's distributed temperature measurement is based on
the proven Raman-Optical Time-Domain-Reflectometry (OTDR)
technique. An optical laser pulse propagating through the sensor
fiber gets scattered light back to the transmitting end, where it is
analyzed using a patented code sequence measurement concept.
The backscattered light is spread across a range of wavelengths.
Some of these wavelengths are affected by temperature changes
while others are immune. The intensity of the Raman signals is a
measure of the temperature along the fiber. By very accurately measuring the difference in the signal intensity of the backscattered
light an accurate temperature measurement can be made.

The local position of an alarm temperature is determined by
measuring the arrival time of the returning light pulse similar to a
radar echo showing the distance of a car or plane. This enables the
FiberSystem PTS Controller to provide an exact location of a fire
or hot spot anywhere along the sensor's length. Temperatures are
recorded as a continuous profile. The system is also capable of
providing graphical representation of the fire size and direction of
fire spread based upon the length of sensor in alarm.
System Design F eatures
Each PTS Controller is provided with four (4) programmable optically decoupled inputs, and forty four (44) programmable voltage
free outputs (one trouble relay output and forty three alarm relay
outputs) for reporting to a main fire alarm panel. The trouble relay
is normally closed and the alarm relays are normally open. Reverse
logic can also be programmed. The resulting ability to switch
between these two states provides several options for the user. For
example, the output can be used to operate external audible signals
or warning lamps.
• RDY - Switches on after booting as readiness indicator.
• ALARM - On when the temperature value measured on the
corresponding measuring channel exceeds the predefined alarm
Fiber Optic Sensor Cable:
Protectowire PFS Series Fiber Optic Sensor Cable has unique
advantages over other types of detectors, especially when difficult
installation factors or severe environmental conditions are present.
When used with a Protectowire FiberSystem 8000 PTS Controller,
temperature measurement on the Sensor Cable takes place at periodic intervals to provide a continuous temperature profile.
The sensor cable consists of a non-metallic or stainless steel tube
with an outside diameter of 1.2 - 1.8 mm (.05 - .07 inches). In the
The system can be integrated easily into your management platform (e.g. SCADA systems) by either directly communicating
over Ethernet (TCP/IP) using SCPI (Standard Commands for
Programmable Interface), or Modbus RS232, RS422, RS485 and
TCP/IP. Also optionally available is a relay extension module that
can trigger up to 256 relays per channel. The relay extension module is used to extend the forty four (44) standard embedded relay
outputs provided in the PTS Controller.
System Architecture
Controller: The PTS Controller is housed in a NEMA 1(IP20)
type enclosure. The Controller contains the system operating software, transmitter, receiver, and digital processor.
• Transmitter: This unit contains the laser and its control. Its
function is to generate the laser light by means of a semiconductor laser diode, and to control its overall operation.
• Receiver: This unit contains the entire optical design including
coupler and optical receiver. Its function is to couple the laser
light generated in the transmitter module to the sensor cable
fiber. Additionally, the back-scattered light returned from the
sensor fiber is distributed to the individual measurement channels,
converted optically/electrically and amplified.
• Digital Processor: The digital processor controls the overall
operation of the Controller and the temperature measurement
process. Based upon the data it receives, the unit calculates the
temperature profile along the sensor cable, controls alarm
processing based upon stored zone definitions, manages the
integrated four (4) inputs and multiple outputs, and communicates over the serial interface or via Ethernet.
tube are two independent color-coded quartz fibers. Depending
upon the model selected, the tube is clad with a layer of stainless
steel wire or Aramid yarns. The sensor's core is then sheathed in
a flame retardant jacketing material to a diameter of 4 mm
(.16 inches).
System Configuration:
• Power supply and a power source in compliance with UL
requirements (10 to 30 VDC).
• The fiber optic sensor cable with PTS Controller shall be
connected to a listed or approved fire alarm control panel
through up to forty four (44) potential free contact outputs.
Alarm and trouble conditions are conveyed by this means
(43 alarm, 1 common trouble).
• Alarm confirmation of the fire alarm control panel occurs by
means of up to four (4) opto-decoupled Controller inputs.
Alternatively, this can also take place by means of a computer
(if connected).
• The Controller can be connected to a PC by USB or LAN. This
allows system parameterization to be carried out and measurement information to be read and displayed.
The Controller is provided with active system status indicators,
color display, one (1) power disconnect switch, and one (1) reset
switch mounted inside the enclosure. The LED visual indicators
are grouped into four functional categories and signal the following
Operating Modes: Standard PTS Controllers are configured to
operate as a Single Channel Single End device. In this configuration, if a fiber break caused by fire or mechanical damage should
occur, the monitored area after the fiber break would be lost, and
would no longer be capable of initiating an alarm.
• TX/RX - Indicates communication activity between the PTS
and controlling computer.
When a Multi-Channel Controller is utilized, it incorporates additional optical connectors. These connectors allow the device to
operate in a Multi-Channel Single End mode, or a Multi-Channel
Closed Loop mode.
• FAULT - Indicates the PTS has an error or "trouble" condition.
In a Multi-Channel Single End configuration, the Controller performs single ended measurements on two or four separate fibers
thus providing distinct detection "channels." In the Multi-Channel
Closed Loop operating mode, the sensor cable is installed in a loop,
and the Controller performs measurements from both ends of the
fiber. If a break should occur in the fiber, the entire sensor cable
length continues to be monitored from both directions thus ensuring detection over the entire length of the sensor cable up to the
point of the break.
Zones: A single length of sensor cable can be partitioned into different "zones" for various requirements (e.g. equipment shutdown,
ventilation, and extinguishment release). Zones can be defined as
desired and even overlapped, increasing system control capabilities.
All FiberSystem 8000 PTS Controllers provide up to 256 alarm
zones per channel. Individual alarm parameters and outputs can be
assigned to each zone. The PTS Controllers also provide the ability
to localize fire location with great accuracy. This ability is particularly useful for connecting the Controller to a control panel with
extinguishing release capabilities.
(16 - 33 ft.); Size 3 = 10 to 50m (33 - 164 ft.); Size 4 = 50 to
100m (164 - 328 ft.); Size 5 = 100 to 500m (328 - 1640 ft.).
Direction of Fire Spread: Most fires have a dominant direction of
spread caused by such factors as air current, construction, or
combustibles. By knowing this propagation direction, the counter
action of the emergency services can be directed to the less hazardous side of the fire. The visualization software provides three
different options for determining the direction of fire spread.
• No direction - localized.
• Toward the PTS Controller (beginning of the sensor cable run).
• In the direction away from the PTS Controller (toward the end
of the sensor cable run).
In the case of a sensor cable closed loop set-up, the "Point of
Return" needs to be set to ensure that the propagation direction is
displayed correctly.
Alarm Resetting: Resetting an alarm condition on the PTS
Controller is done by using one of the four input contacts, the
internally mounted reset button, or via the PTS Configuration software.
Configuration Software is provided with each FiberSystem 8000
Controller. This software can be easily adapted to specific customer
requirements, and offers numerous options for displaying and processing the recorded alarm and temperature data. The software
makes it possible to create multiple zones along a single length of
sensor cable, select multiple alarm initiating criteria, provide unique
alarm visualization graphics, and to configure zone related alarm
generated outputs for event handling.
Interface Solutions
The FiberSystem 8000 can easily be integrated into SCADA
Systems, direct process control or external connections to fire alarm
control panels. The following special order accessory products can
be used to extend the standard PTS interfaces:
Alarm Initiation: Temperature measurement on the sensor cable
by the PTS Controller takes place at periodic intervals known as
the measurement cycle time. An alarm is triggered at the end of
the measurement cycle if any one of the following alarm criteria is
exceeded in a zone:
• Maximum temperature per zone.
• Temperature difference between a measurement location and the
zone average (zone differential).
• Temperature development per zone in terms of time (time
differential / rate-of-rise).
Unlike conventional systems, these freely programmable alarm settings are user selectable and can be adapted individually by zone
depending upon the specific requirements of the application.
Different alarm sensitivities on the same sensor cable run allow precise and selective initiation of counter measures.
Fire Size: The PTS Controllers have the unique ability to provide
information on the size of the fire by displaying relevant information in the visualization software. Fire size parameters can be
individually set for five different sizes during parameterization.
Default values are: Size 1 = < 5m (16 ft.); Size 2 = 5 to 10m
Interface Box for Modbus: This device provides access via the
Modbus protocol over RS232, RS422, or RS485, as well as over
TCP/IP. The Modbus protocol offers, complete temperature trace
data, each alarm parameter per zone, and several status conditions
like fiber break.
Through a virtual host concept, the data is available for each sensor
(channel) as a Modbus unit. This means that only one unit is
required even for multiple channel operation. Ten thousand register
holdings and three thousand register coil definitions can be flexibly
assigned for each Modbus unit.
Relay Control: When the application requires the use of more
than the forty four (44) embedded relay outputs of the PTS
Controller, a Relay Controller Set should be used. In combination
with the Relay Extension Set it is capable of controlling up to 256
relay outputs per channel. Each relay output can be flexibly
assigned to any defined alarm condition.
The Relay Controller Set includes:
• Power Supply (More than 128 relays requires a second power
• Pre-programmed Relay Controller
• One (1) digital output module, one (1) end module
• Eight (8) relays
The Relay Extension Set adds another Digital Output Module and
eight (8) relays. As an example, to offer forty-eight relays, one Relay
Controller Set and five Relay Extension Sets would be needed.
