PROTECTOWIRE® linear heat detector
Protectowire Linear Heat Detector is a proprietary cable that detects
heat anywhere along its length. The sensor cable is comprised of two
steel conductors individually insulated with a heat sensitive polymer.
The insulated conductors are twisted together to impose a spring
pressure between them, then wrapped with a protective tape and
finished with an outer jacket suitable for the environment in which the
Detector will be installed. Protectowire is a fixed temperature digital
sensor and is therefore capable of initiating an alarm once its rated
activation temperature is reached. At the rated temperature, the heat
sensitive polymer insulation yields to the pressure upon it, permitting
the inner conductors to move into contact with each other thereby
initiating an alarm signal.
In all places with severe environmental conditions such as:
cable trays
power distribution
street and railway
tank farms
flammable liquids
Cable types
The Detector’s product range consists of four distinct types of cable. Each designation identifies a specific
outer jacket material which has unique characteristics that have been selected to accommodate the widest
range of installation environments.
EPC consists of a durable flame retardant vinyl outer jacket. This series is best described as multi-purpose and
is well suited to a wide range of both commercial and industrial applications. The outer jacket provides good
all-around performance for most installations. It features low moisture absorption, resistance to many common
chemicals, and excellent flexibility at low temperatures.
XCR Fluoropolymer Jacket utilizes a high performance fluoropolymer jacket. This detector is specifically
designed for use in applications where extreme environmental and product performance criteria must be met
XLT Vinyl Polymer Jacket is a unique detector that has been designed for use in cold storage facilities and other
applications that require a low alarm activation temperature. This detector has been UL and FM tested to
TRI-WIRE Dual Temperature Vinyl Jacket is a unique dual temperature detector which is capable of initiating
separate pre-alarm and alarm signals once each of its rated activation temperatures is reached.

SecuriSens® ADW 511 A
Fires and explosions cause sharp increases in ambient temperatures:
the warmed air expands. Securiton used this simple physical principle
in this development of the SecuriSens ADW heat detector. The device
quickly and reliably detects even the slightest increase in temperature,
and is indispensable in harsh environments – those involving corrosive
gases, extreme humidity, high temperatures or contaminated air.
Installing SecuriSens ADW can protect lives, prevent damage and
reduce insurance liabilities. Thousands of customers around the world
benefit daily from the high degree of safety provided by this fast fire
detection system. Such effective fire protection is easy to achieve,
made possible by the use of user-friendly programming and evaluation
routines, combined with a maintenance-free and failsafe operation.
The SecuriSens ADW 511A is a linear rate-of-rise and maximum
temperature detector and works on the principle of the change in
volume of gases when there is a change in temperature. It consists of
a copper sensor tube of up to 130m in length (stainless steel or Teflon
tubes are available for use in particularly difficult environmental
conditions, available upon request) and a detector case. Pressure is
artificially created in the sensor tube, with a fully electronic pressure
sensor constantly measuring the absolute pressure in the tube, with a
microprocessor carrying out the evaluation. The sensitivity of the ADW
511A can be set via a PC using software, with disturbance factors
such as weather-related variations in temperature being filtered out.
Damage to the sensor tube is also recognized, by means of a precisely
defined surplus pressure being created in the sensor tube by means of
a test motor and a pressure pump. The ADW 511A's very robust
construction makes it particularly suitable for use in hazardous areas
(tunnels, hazardous areas, industrial applications ...). Product versions
ADW 511 A Ex I and Ex II are ready for hazardous EX areas.

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 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.
Unique zoning capabilities. A single length of sensor can contain up
to 256 zones.
Multiple alarm initiating criteria by zone.
Programmable custom operating logic.
Capable of continuous temperature monitoring.
Graphic display of temperature profile, fire size, and spread using
computer interface.

SecuriSens® LIST line-type heat detector
Fire detection with SecuriSens LIST heat detectors
Fire detection with SecuriSens LIST heat detectors begins where all
other detectors reach their limits. Dust, heat, smoke, exhaust fumes
and other interference factors have a significant impact on detecting
fires when using conventional fire detectors. However, it is exactly
under such difficult conditions that the fire risk is so great and it is
vital to ensure quick and reliable detection – such as in tunnels,
industrial facilities, power plants and car parks. With the SecuriSens
LIST line-type heat detectors, we provide systems that can enable
the rapid localisation of a fire – even when used in harsh, aggressive
environments. SecuriSens LIST detects incipient fires in record time.
The sensor cable contains highly sensitive addressed sensors whose
response behaviour can be programmed individually. The sensor
spacing in the cable can also be selected individually, meaning you can
then set up a monitoring system that is tailored exactly to the
specific risk profile of your object and the local installation regulations.
You can then profit from extremely precise, rapid and reliable fire
Two systems, one principle for maximum safety
The SecuriSens LIST system with SEC 20 sensor cable ensures
maximum safety in tunnels and when monitoring large areas. The
SecuriSens d-LIST system with SEC 15 sensor cable is primarily used in
industrial facilities and when monitoring smaller areas. Both systems
are the result of a wealth of specialist expertise. Evaluation of the
sensor data is made according to the maximum temperature behaviour
and differential behaviour. In doing so, proven evaluation algorithms
minimise the risk of false alarms. Configuration is tailored exactly
according to your requirements. You can specify the detection areas
easily with independent alarm thresholds as well as individual pre-signal
thresholds. Every second counts when reacting to an emergency, which
is why the systems have transparent communication without any
friction losses. They offer interfaces to superordinate systems and open
data protocols, such as Modbus or IEC. The temperature values and
events are visualised on the cable terminal processor or the PC. The
SecuriSens LIST systems also open up interesting options in terms of
dimensioning several cable terminal processors can be networked with
one central master.
The sensor cable – intelligence from start to finish
Robust, clever and precise – the SEC 15 and SEC 20 electronic sensor
cables impress thanks to their alertness, reliability and practically
unlimited possibilities. Their measuring points record the temperature
at a resolution of 0.1 °C. The functionality of all sensors is permanently
checked by the cable terminal processor so that uninterrupted
monitoring of your object is ensured. With their sophisticated design,
the sensor cables offer the best possible conditions for extremely
long-term use. The closed aluminium shielding protects against
damaging EMC influences. The halogen-free outer sheathing is flame
retardant according to DIN EN 60332 and extremely durable. The
sensors still work reliably, even when the temperature reaches a
maximum of 120 or 200 °C for short periods. Cable strain relief is
provided on the fill material surrounding the two-wire or four-wire ribbon
cables. Another positive aspect is that these clever cables are
maintenance-free and can be repaired quickly and easily in the event of
