Important - Read before commencing installation
Please read this instruction leaet thoroughly before commencing installation and ensure all
recommendations and advice are followed.
Install the ProReact EN Analogue Linear Heat Detection System accordingly to meet local and country
installation requirements.
For UL Listed installations, ProReact EN Analogue linear heat detection cable must be installed in
accordance with NFPA 70 & 72, NEC 760 (National Electric Code).
For EN54-22 approved installations, ProReact EN Analogue linear heat detection cable must be installed
in accordance with DIN VDE 0833-2 or country equivalent (such as BS 5839-1).
Installation of the ProReact EN Analogue Linear Heat Detection System should only be undertaken by
trained, qualied personnel.
Avoid allowing the detection cable to come in contact with any material which acts as a
heat sink. This may aect the activation of the cable in alarm situations.
Do not connect lengths of ProReact EN Analogue Linear Heat Detection cable in ‘T’
connections or spurs.
Do not paint the detection cable.
Do not place the detection cable under excessive tension.
Do not bend the detection cable at right angles. Refer to the minimum bend radius
value for each sensor cable type.
Avoid subjecting the detection cable to mechanical damage which could result in false
activation.
Avoid laying the detection cable in areas where heavy trac may result in the cable
being crushed.
Do not use ProReact EN Analogue sensor cable with dierent three letter codes on
the same zone. ProReact EN Sensor cables with dierent three letter codes must use
separate ProReact EN Analogue Composite Control Units.
Support the detection cable at a maximum of 0.5m (1.5ft) intervals.
Test the detection cable on the reel, before installation, using a multimeter.
Ensure the maximum ambient temperature of the application will not exceed the
allowed maximum application temperature for the chosen alarm temperature.
When protecting an area, ensure adjacent runs of detection cable are spaced at less
than or equal to the maximum allowed spacing detailed in the corresponding re
alarm system design standard.
Ensure the detection cable is not in contact with any material which may conduct
heat onto the cable. A silicone sleeve must be placed between the xing clip and
detection cable.
Ensure any cable glands used are tightened to form a secure, moisture proof seal
around the detection cable. Some applications may benet from silica gel packets in
the control unit and end-of-line enclosures to dry out any residual moisture.
Periodically test the ProReact EN Analogue Linear Heat Detection system to ensure
correct operation of the system.
Ensure between 1% to 3% of the ProReact EN Analogue sensor cable is accessible
post-installation to allow functional testing to be carried out

General Overview
Introduction
Thermocable’s ProReact EN Analogue Linear Heat Detection (LHD)
system comprises of ProReact EN Analogue Linear Heat Detection (LHD)
sensor cable, a ProReact EN Analogue Composite Control Unit and a
ProReact EN Analogue end of line unit. The system oers alternative
overheat protection in a vast range of applications and industries, from
power generation to oil and gas industries.
The ProReact EN Analogue technology oers separate Pre-Alarm and
Alarm outputs in order to maximise functionality, coupled with open
and short circuit detection and discrimination.
Ambient temperature compensation maintains alarm temperature
accuracy. The system is also resettable following an overheat or re
condition if the components are not exposed to temperatures above
the maximum recoverable temperature.
Using a zone or switch monitor, or input/output module, the
ProReact EN Analogue LHD system can easily be interfaced to
an addressable loop. Alternatively it can be directly connected
to the initiating zone of any conventional re alarm control panel
(as shown below).

Theory of Operation
The ProReact EN Analogue LHD system uses a heat sensitive cable to
monitor an area, critical equipment or the like, for an overheat or re
condition.
The ProReact EN Analogue Composite Control Unit continuously
monitors the resistance of temperature sensitive polymers within the
ProReact EN Analogue LHD cable. The resistance of the ProReact EN
Analogue LHD cable decreases as the temperature around the cable
increases. An abnormal change in resistance, due to an overheat
condition, along the cable triggers either a Pre-Alarm or Alarm on
the ProReact EN Analogue Composite Control Unit. The ProReact EN
Analogue Composite Control Unit can be interfaced to a conventional or
addressable re alarm system.
For the alarm temperature to be stable across a range of ambient
temperatures, the ProReact EN Analogue Composite Control Unit
measures the average ambient temperature across the entire cable and
dynamically adjusts the alarm threshold accordingly.
It is important therefore to ensure that the ProReact EN Analogue
Composite Control Unit is set up correctly and the cable resistance and
the average ambient temperature as shown on the ProReact EN Analogue
Composite Control Unit are as expected. See the Commissioning section
for more information about setting up a ProReact EN Analogue LHD
system.
Alarm Temperatures
The ProReact EN Analogue LHD system is designed so that an alarm will
be triggered when the temperature around a section of ProReact EN
Analogue LHD cable (equal to 3% of its total length) reaches a nominal
alarm temperature predetermined by the chosen setting on the ProReact
Composite Control Unit (as shown in Table 1).
The actual exposure temperature required to trigger an alarm will
be lower than the nominal alarm temperature (as shown in Table 1)
if a larger section of ProReact EN Analogue LHD cable is exposed
to an abnormal rise in temperature. Likewise, the actual exposure
temperature will be higher that the nominal alarm temperature
if a shorter section of ProReact EN Analogue LHD cable is exposed
to an abnormal rise in temperature.
When the sensor cable is installed and operated in hotter environments,
the sensor cable may need to be exposed to a higher temperature than
that required in a cooler environment in order to trigger an alarm for a
given setting on the ProReact EN Analogue Composite Control Unit. In
such circumstances, the ProReact EN Analogue Composite Control Unit
dynamically adjusts the alarm threshold to reduce the likelihood of false
alarms.
Refer to the “Application Temperatures” section for more information on the
typical and maximum application temperature for each controller setting.
Please refer to the charts on the following page for illustrative examples
of the expected temperature a given portion of Analogue LHD cable
must be exposed to in order to trigger an alarm by ProReact Composite
Control Unit setting.
Rate-of-rise activation
Note: for the Class A1I/A2I, 54°C and 64°C Alarm settings the control
unit will also trigger an alarm if approximately 2% of the sensor cable is
heated at more than 15°C per minute for longer than 3 minutes. This will
show as a rate alarm (see step 25 in the commissioning procedure).

Pre-Alarm Temperatures
The ProReact EN Analogue LHD system has an in-built Pre-Alarm feature that enables users to receive an early notication of a temperature increase before
an alarm is triggered. Users can take advantage of this additional functionality in several of the available settings. Table 2 presents the available Pre-Alarm
temperatures for selected settings. See the Commissioning section for more information about setting up a Pre-Alarm temperature.
Application Temperatures
In order to minimise false alarms and ensure the ProReact EN Analogue LHD system responds as expected, it is very important to make sure that the
chosen control unit setting for selecting the alarm temperature is suitable for use given the typical and maximum application temperatures that are likely
to be expected during normal operation in the installed environment. Refer to Table 3 below for the recommended typical and maximum application
temperatures for a given alarm temperature selection.

Mounting Instructions - ProReact EN Analogue Sensor Cable
For area protection applications, the ProReact EN Analogue Sensor Cable
should be mounted securely to the ceiling, or equivalent, above the area
requiring detection. A suitable xing method is shown in the Figure 7.
When protecting critical pieces of equipment the ProReact EN Analogue
Sensor Cable should be mounted in such a way as to minimise vibration,
accidental damage caused by impact or shock and to minimise heat
transfer from metal parts (for example).
Always ensure a silicone sleeve is placed between the
sensor cable and the mounting bracket or xing.
The recommended spacing between clips is 0.5m.
It may be necessary to place more supports around bends
or corners and other transition areas.
Avoid excessive tension in the sensor cable.
No greater than 50N.
Always use a reel stand or equivalent when unspooling
the sensor cable from the reel.

Area Protection
The ProReact EN Analogue LHD system is suitable for area protection
applications where the sensor cable is typically installed on the ceiling,
for example in a warehouse. The sensor cable should be installed with
a minimum distance between the cable and ceiling of 20mm. This is
especially important when the sensor cable is mounted to a uninsulated
ceiling where a warm boundary layer can develop and delay the
operation of the detector.
For DIN VDE 0833-2 compliant installations the maximum horizontal
distance from the sensor cable to any point on the ceiling is given as C in
Table 4.
Therefore the distance between two parallel runs of sensor cable (shown
as A in Figure 8 below) must not be greater than the distance shown in
Table 4. For Class A1I, the maximum ceiling height (h) is 9m (see DIN VDE
0833-2 section 6.1.5.3).
For BS 5839-1 compliant installations or UL 521 and NFPA 72 compliant
installations, the maximum horizontal distance between any point in a
protected area and the linear heat detection cable nearest to that point is
given as C in Table 5. This spacing is also in accordance with the spacing
detailed in the UL listing (see page 3) for UL 521 and NFPA 72 installations.
Note: for pitched ceilings a greater spacing may be allowed. Refer to BS
5839-1 Section 22.6 for more information.
Note: for UL 521 and NFPA 72 compliant installations, refer to section 17.6
of NFPA 72 for guidance when installing linear heat detection on pitched
ceilings or where obstructions may be present.
The recommended spacing between clips is 0.5m.
Ensure the spacing between adjacent runs of sensor
cable is in accordance with the recommended guidelines,
such as Section 6.2.7.12 of DIN VDE 0833-2, Section 22.6

Hazardous Area Installation
The ProReact EN Analogue Composite Control Unit is designed to be
connected to any standard re alarm control panel or addressable monitor
module. It is intended to be powered via the 24Vdc switched power output
which is interrupted when the control panel is reset or via a battery-
backed EN54-4 power supply for EN54 compliant installations or UL listed
power supply with a UTRZ category code for UL compliant installations.
The remote reset function allows the ProReact EN Analogue Composite
Control Unit to be reset from a remote point. In order to trigger a reset
supply 5 - 28Vdc (approx 2mA max) for at least 3s to the remote reset
input.
The ProReact EN Analogue Composite Control Unit includes a Modbus
RS-485 RTU/ASCII output. This can be used to read back additional
information from the ProReact EN Analogue system as well as the fault
and alarm status. For example, by reading the sensor cable ambient
temperature via the Modbus output, it is possible to use the ProReact
EN Analogue Composite Control Unit and Sensor Cable as a distributed
temperature sensor.
For installations in hazardous areas please refer to the ProReact Analogue
Hazardous Area installation instructions for suitable recommendations
and advice.

Typical System Wiring
The components of the ProReact EN Analogue LHD system should be connected in the manner shown in Figure 10.
Connect the sensor cable to the end-of-line unit rst then
measure the connections using a calibrated multimeter at
the other end without the cable plugged into the control
unit. The values should match those shown in Table 6.
The connection of the clear cores in the sensor cable into
the ProReact EN Analogue Composite Control Unit are
polarity sensitive. They must go in the correct order (as
shown below).
Make a note of the cable three letter code. Do not mix and
match sensor cables with dierent three letter codes on
the same control unit.
Take care to cut the shield wire back at the end-of-line unit.
Do not mount the end-of-line unit on a metal surface.
The calibration resistance is the value between the white core
and the clear core which is adjacent to the red core in the
sensor cable (as shown in Figure 10).
Record all the sensor cable serial numbers, the sensor cable
three letter reel code and the measured calibration resistance
on the label in the control unit (shown in Figure 10).
Figure 10: Typical System Wiring Diagram for the ProReact EN Analogue LHD System
Table 6. Expected resistance values during commissioning
Red Wire Resistance Red core to adjacent clear core Between 100Ω (0.10kΩ) to 2200Ω (2.20kΩ)
Calibration Resistance Clear core to white core Between 500Ω (0.50kΩ) to 9000Ω (9.00kΩ)

Useful information
Leader Cable
Leader (non-sensing) cable may be used between the ProReact EN
Analogue Composite Control Unit and the ProReact EN Analogue Sensor
Cable. Only leader cable approved for use with the ProReact EN Analogue
LHD system should be used between the ProReact EN Analogue
Composite Control Unit and ProReact EN Analogue Sensor Cable.
The ProReact EN Analogue junction box must be used to connect the
leader cable to the detection cable.
Low Temperature Considerations
ProReact EN Analogue Linear Heat Detection cable is suitable for use in
ambients down to -40°C (-40°F). Such conditions occur in cold storage
freezer warehouses and outdoors for example.
When installing LHD cable in low ambients or for use in low temperature
conditions careful consideration of the conditions and environment
should be undertaken.
If possible, do not install the LHD cable when the ambient temperature
is below -10°C (-14°F). The materials within the cable will become less
exible and are more prone to damage during installation. If the ambient
temperature is likely to drop signicantly after installing the cable take
into account linear shrinkage of the cable when attaching support
brackets. The cable can shrink in length by 1-2% at -40°C (-40°F).
A silicone sleeve insulator must be placed around the cable before
clipping into the support bracket. This prevents damage to the cable and
reduces the heat sink eect of the clip.
The minimum bend radius of the detection cable should be increased
to twice (2x) the specied value shown on page 12 to account for the
reduced exibility. The maximum distance between support brackets
should be no more than 0.5m (1.5ft) and it is important to support the
cable close to either side of any bend.
Ensure any junction boxes or other enclosures are waterproof and
suitable for the expected operating temperatures.
Refer to the Technical Specications for the minimum operating
temperature of each component in the ProReact EN Analogue
LHD System.
Joining Sensor Cable
It may be necessary to connect two or more lengths of analogue linear
heat detection cable together during installation or the lifecycle of
the system. For example, if the ProReact EN Analogue LHD cable gets
damaged or has exceeded the maximum restorable temperature of 125
°C (257 °F), the section can be removed and a new section spliced in its
place. Likewise, during installation two lengths of analogue linear heat
detection cable may be connected together to extend the zone or to aid
in physical installation of the cable. Only connect analogue linear heat
detection cables with the same three letter code together.
The ProReact EN Analogue Junction Box should be used to connect
two ends of analogue sensor cable together. The ProReact EN Analogue
Junction Box includes two cable glands and 5 connection terminals
mounted on a DIN rail. The 4 cores and shield wire should be connected
to the corresponding cores and shield wire on the adjoining cable using
the connection terminals.
When replacing a section of the detection cable
for any reason, the section including at least 3m
(10ft) either side of the damaged area should
be replaced.
Ensure any replacement cable used to splice in a
new length is the same three letter code as the
existing cable. Do not mix and match sensor cable
with dierent three letter codes on the same
control unit.
Ensure the total length of sensor cable after
joining is between the minimum and maximum
zone length (see page 12 for details).
The maximum length of leader cable between the
control unit and the sensor cable is 250m
Note: the use of leader cable between the control unit and sensor cable
is not VdS approved.

Commissioning
Before beginning to commission the system ensure that the installation of the control unit, sensor cable,
end-of-line module and any junction boxes have been carried out in accordance with the information
provided herein. Incorrect installation may result in unwanted alarms, faults or malfunction of the system
even after successfully commissioning the control unit.
1. If the control unit is being commissioned for the rst time the screen
will prompt whether the control unit is to be programmed using the
built-in display and SET and SELECT buttons. (Alternatively, selecting ‘No’
will continue and the screen will show “FAULT: NO SETUP”. The control
unit may be programmed with a laptop in this instance).
2. If “Yes” was selected in the previous step, enter the calibration
resistance. (See “Typical System Wiring” for how to measure the
calibration resistance). The value can be changed by pressing the SELECT
button to cycle through 0-9. Press SET to move to the next column in the
resistance reading.
3. After the values have been entered the control unit will prompt you
to double check the value. Press SELECT to change to “Yes” if the value
shown is correct and press SET to continue. Otherwise select “No” and
press SET to return to step 2.
4. The control unit will prompt to double check the zone length based
upon the entered calibration resistance. Press SELECT to change to “Yes”
and then press SET to continue. Otherwise select “No” and press SET to
return to step 2.
5. Enter the three letter code corresponding to the sensor cable.
The three letter code is printed on the reel label and once per metre on
the sensor cable. You should record the three letter code on the label
axed to the reverse of the control unit lid during commissioning
(see page 10).
6. Conrm the entered three letter code is correct. Press SELECT to
change to “Yes” and press SET to continue. Otherwise select “No” and
press SET to return to step 5.
7. If the installation is in a hazardous area, press SELECT to change to
“Yes” and press SET to continue. Otherwise select “No” and press SET to
continue to step 10.
