Software Installation
Procedure
• Connect the detector to power and connect the interface module to the
detector’s test socket or the terminal block, as defined in annex 1.
• Connect the output of the interface module with the serial COM port of
the PC.
• After double clicking on the Setup_PROXX.exe the software will be
installed on your computer (xyz indicates the software release version V
xy.z).
• Once installation is complete, the new folder ‘PRO’ has been created
and includes the following subdirectory and files:
Ini – Folder: Contains the necessary detector Ini-files. Each detector
model requires its specific Ini-file.
PRO.cfg-file: Contains specific data relevant to the display structure,
logo on bitmaps etc. (do not delete).
PRO.exe-file: Installation program for set-up and signal display.
• As soon as the PRO.exe program is started the following additional
folders are created:
Bmp-Folder: Contains all pictures of the analog signals taken by
pushing the take picture button in the scope function of the program.
Dat-Folder: If the debugger or statistics-function has been activated
and a file name has been defined a data-file will be created.
CFG-Folder: Contains configuration of a particular detector. When
saving the settings of a detector a dialog opens that asks the user for a
corresponding filename. Upon entering in the appropriate name and
selecting OK, the software saves the parameters in a file in the “CFG”
folder.
For additional Information or ordering of additional Ini-files please contact
the manufacturer.

Annex 3: Installation Software
Introduction
The installation software is available as an accessory for alignment, setting
up and fault finding. It can be used for remote programming and
verification of all detectors connected to the same RS485 data bus and is
recommended for verification of all installations, in order to optimise the
performance of the detectors. If more than one detector is operated over
the same communication link it is necessary that the detectors have
different addresses (IDs).
For operation with a standard PC an RS232 to RS485 converter is required.
The interface box IF 485B is available as an accessory.
Application of the Installation Software
The installation software is a most useful tool for remote programming and
for checking the alignment of the detectors. It greatly facilitates the
optimisation of an installation to suit a particular site.
Independently of the position of DIP–Switches 1 and 2 (hardware or
software settings) the program is capable of displaying the actual parameter
settings, as well as the analog signals of the selected detector.
For remote programming purposes DIP–Switches 1 and 2 have to be
switched to on-on position (software settings). Now all parameter settings
can be altered with the software.
The software is particularly helpful in situations where a detector is
operated under conditions near the recommended operating limits of height,
detection range and target speeds. The information supplied by the PC
display should be used to monitor the detection performance of the detector
and make adjustments if required.
Depending on the site’s animal activity, vegetation moving in the wind
and/or other sources of disturbance, it is possible that unwanted alarms
occur. Monitoring and interpreting the information supplied by the
installation software will help find the best solution, either by adjusting the
alignment and/or settings of the detector or by removing disturbance
sources from within the field of view.

Annex 2: Two Way Communication RS485
Introduction
The PRO-250H is equipped with a RS485 interface for two-way
communication between the detector and a PC or other control device. This
communication link is used for detector set-up and remote adjustments as
well as for signal monitoring.
It can either be used temporarily for installation or permanently wired for
remote access to the detector from the control room. RS485 can
accommodate up to 32 detectors on the same data bus with a maximum
bus length of 1000 m – provided the detectors have all different IDs and the
data link is properly terminated.
There is no terminating resistor built into the detector. The last detector on
the bus, on the opposite side of the IF485B interface module, also needs a
terminating resistor of 120 Ohm. This can be accomplished by adding a
resistor between the wires RS485A and RS485B.
Temporary Connection for Installation and Configuration
For this, the use of the interface module IF 485B is recommended (refer to
Section 17.1 - Interface Module IF 485B and Installation Software for
details). The test socket carries V+, GND and the two RS485 ports A and B.
The detector must be opened for access to the test socket and closed again
after the adjustments.
Installation and Configuration for Permanent Wiring
For permanent connection of the RS485 communication link to a control
room the two RS485 ports A and B are also accessible on the terminal
block. The connector board contains all components required for protection
of the communication link.
In this mode it is not only possible to do all adjustments and signal
monitoring remotely from the control room but also eventually to use the
RS485 link for alarm signalling.
When planning to use the PRO-250H in this configuration, please consult
the manufacturer for details about the protocol definitions.
For the RS485 communication bus it is recommended to use twisted pair
wiring to avoid disturbance signals.

Overview
The PRO-250H is a highly sensitive passive infrared detector designed for
detection outdoors with a narrow, curtain-shaped differential field of view.
They incorporate microprocessor-controlled signal processing, including
signal shape analysis, adaptive threshold level by feedback of
environmental effects, temperature compensation and rejection of
disturbance signals.
Sensitivity adjustments are done with DIP–Switches for each individual unit,
to alter the required detection range in order to adapt to the specific needs
of an installation.
In addition to the hardware settings, adjustments can be made in a two way
communication mode and signals displayed on a PC screen by using the
optional installation software and RS485 communication interface module.

• Any liability for direct or indirect damage resulting from the use of the
PRO-250H as a detection device is explicitly disclaimed.
• The information in this product manual is based on testing of samples
taken at random from production and believed to be representative,
E&OE (Errors and Omissions Excepted).
20.0 Wiring the Alarm Outputs
If used with a product that supports tamper detecting inputs, the PRO
detector can be connected to signal both cover tamper and alignment
tamper.
The product (eg Xtralis ADPRO AFT) should have the alarm input
configured as Dual-End-of-Line Normally Closed. The PRO detector should
be wired as below:
1.0 Mounting and Installation
The mounting structure should be stiff enough and resistant to significant
deflections in windy conditions. Movement of the PRO-250H caused by
vibrations or other movements will result in swings of the field of view
covered by the PRO-250H and could cause disturbance signals. These
unwanted signals may lead to an increase of the alarm threshold level,
which reduces the detection probability, or in certain cases can lead to
unwanted alarms.
As an original accessory the mounting bracket AD 653 is available.
The clamp around the body of the PRO-250H should be positioned
approximately half way between the front window and the back cover
to avoid slight deformations of the body near the seals at each end.
CAUTION: It is very important that the back cover of the PRO-250H
is securely tightened. It is not sufficient to close the
cover only to the point where the O - ring starts to rub
against the inner wall of the housing. It must be
tightened to the point where it cannot be closed further
with reasonable force when using a lever such as a
screw driver in the groove. There will then be hardly any
gap between the cover and the housing (considerably
less than 1 mm).
The cable entry assembly should not be changed without authorisation
by the manufacturer. It is specifically designed to allow air entry and exit so
that the inside of the PRO-250H is always at atmospheric pressure. This
prevents moisture being sucked into the PRO-250H by a drop in internal
pressure, likely to happen when rainfall rapidly cools down a unit warmed
up in the sun.
The nut on the cable entry assembly should be tightened to clamp the cable
in place with the nylon grip. If the cable diameter is too small to be held by
the grip, insulation tape should be wound around the cable to increase the
outside diameter to a suitable size.
2.0 Hardware / Software Mode of Operation
The PRO detectors can be operated in two modes of operation:
• Hardware mode: The configuration and operation is managed by
DIP–Switches on the PRO detectors. This particularly applies to the
Sensitivity Settings. Note that some configuration changes can only
be made through the installation software.
• Software mode: Through the installation software and an RS 485
connection, the configuration and operation is managed through
software settings. The detectors store their configuration locally in
non-volatile memory.

Installation Manual Xtralis ADPRO PRO-250H Xtralis ADPRO PRO-250H Installation Manual
2 Doc 14866_01 Doc 14866_01 11
3.0 Connecting the PRO-250H
For the definition of the connector board and terminal block refer to
Annex 1: Electronic Board and Terminal Block for details.
3.1 Alarm Signalling
There are three types of alarm signalling from the PRO-250H:
• one SPST potential-free relay contact
• an RS485 two way communication link (refer to Annex 2: Two Way
Communication RS 485 for details).
• 3 individual optocoupler outputs for short, medium and long range
alarm identification.
With the factory default setting, the relay contact opens on alarm. The
output logic and function can be changed using the installation software.
During turn-on time, the relay output is in the alarm state.
3.2 Cover Tamper Switch
To detect attempts to open the PRO-250H, a tamper switch is fitted for the
rear cap. Its contact opens when the cap is unscrewed and it should be
connected in series with the normally closed relay contact.
3.3 Electronics Supply
The PRO-250H can operate on either a 10.5 – 30 VDC or 24 VAC supply. If
using a DC supply, ensure that polarity is correct when connecting power to
the electronic circuit. Protective circuitry will withstand a short period of
inverse polarity, but damage will result if this is not corrected quickly.
3.4 Anti-Tamper Output
To detect if the PRO-250H has been moved, an alignment detection sensor
is located in the unit. If the PRO-250H is moved, the open collector
transistor will activate. The transistor is open circuit in its default non-tamper
state.
4.0 Field of View
The PRO-250H has two curtain-shaped fields of view with independent
detector channels for short, medium and long range detection. The vertical
opening angle is approximately 70° resulting in an uninterrupted curtain
starting at approximately 1.3 m with the PRO-250H mounted at 4.0 m
height and aligned for a maximum detection range of 150 m (refer to Figure
1 – Side View of PRO-250H detection zone).
18.0 Maintenance
The detector has been designed to be virtually maintenance free but the
following precautions are recommended:
1. Visual inspection of the front window for accumulation of dirt on
the outer surface or damage at intervals of approximately 6 months. Clean
the surface with a paper tissue and avoid rubbing dirt into the surface. Use
the same precautions as for a camera lens.
2. Visual inspection of the inside for ingress of water is
recommended at intervals of 6 to 12 months or whenever the unit is opened
for adjustments or tests. Make sure that the sealing gasket is in place
before closing the cover tightly again.
3. Inspection is recommended following extreme conditions such
as snow storms, sand storms, hail etc. to make sure that nothing has been
damaged and the sensitivity is not reduced by accumulation of snow, sand
or dirt on the front window. Snow or dust in front of the window should be
removed by hand or by using of a soft instrument (e.g. a cloth covered
wooden stick).
19.0 General Comment on the PRO-250H
• Despite the advanced design and state-of-the-art features of the PRO-
250H it is in the nature of a Passive Infrared Detector that an absolute
detection probability and freedom from nuisance alarms cannot be
achieved, masking of the PRO-250H cannot be excluded.
• Detection is a function of thermal contrast, speed and size of a target
crossing the field of view. Contrast conditions can vary significantly in
the course of the day and year.
• Detection depends also on the sensitivity settings, the exact aiming and
the prevailing weather conditions, as well as the nature of the target
and background.
• The detection pattern and frequency response of the PRO-250H has
been optimised for the detection of human size targets crossing the
field of view in an upright position at speeds in the range of 0.2 - 5.0
m/s (0.6 - 16 ft/s).
• Detection of slow moving targets at long range may become uncertain
under weak contrast conditions. It is strongly recommended to limit the
zone length to less than the nominal range when human targets moving
at the minimum specified speed need to be detected with high
probability.
• Animals or crawling people may or may not be detected depending on
their size, speed, contrast and distance from the PRO-250H.
• It is therefore strongly recommended to combine the PRO-250H with
an alarm verification such as CCTV or a second system using other
physical means of detection (e.g. VMD).

17.3 Pole Mount Hardware AD 653
5.0 Alignment
The detection range of a PIR detector is not limited but a function of size,
speed and temperature contrast of a target against its background. The
PRO-250H should be aligned so that a natural or artificial background at the
end of the desired detection-range terminates the field of view.
Vertical alignment is optimal when the upper edge of the field of view is at
1.5 to 2.5 m above ground at the end of the required detection range,
provided that the field of view is properly terminated.
Coarse alignment can be done visually by looking along the groove on top
of the detector. This line of sight corresponds to the upper edge of the
detection pattern.
Where the detection range has to be limited, a terminating screen can be
used to avoid detection of targets beyond the desired range.
Note: Adverse environmental conditions may reduce the maximum
detection range.
5.1 Typical Vertical Alignment for a required detection range of
150 m
The PRO-250H should be aligned vertically so that at least the lower half of
a person standing upright at the maximum required range will be within the
field of view (refer to Figure 1 – Side View of PRO-250H detection zone
below).
Figure 1 – Side View of PRO-250H
5.2 Typical Horizontal Alignment
Horizontal alignment should be done in a way to avoid unwanted signals
being generated by targets (branches, bushes, fences) likely to be moved
by wind (refer to Figure 2 – Top View of PRO-250H below). Movement
within the field of view will reduce the sensitivity of the PRO-250H by
increasing the alarm threshold level and may lead to unwanted alarms.

Figure 2 – Top View of PRO-250H
6.0 Sensitivity Settings
The various settings of the PRO-250H are made by means of multiple DIP–
Switches on the connector board for varying required detection ranges and
mounting heights.
DIP–Switches 1 and 2 are for sensitivity setting, depending on the
required detection range. If the maximum required range is less than the
nominal range of the detector, it is recommended to reduce the range
setting to reduce nuisance alarms.
Switch 1 and 2 Range
off – off 75 m
off – on 105 m
on – off Max (*)
on – on Software Settings (**)
(*) Factory Setting
(**) With the DIP - Switches 1 and 2 both set to “on”, the overall sensitivity is 100%
factory setting but can be changed with the installation software.
If the sensitivity is adjusted with the installation software, the programmed
value will remain active following a power off.
Operation of the PRO-250H with overall sensitivity set to more than 100% is
not recommended in outdoor applications, as the nuisance alarm rate could
increase significantly.
The PRO-250H is designed for mounting at heights between 2.5 and 4.0 m
above ground. The seventh DIP–Switch is used to set the relative
sensitivity of all detection zones in relation to the mounting height, as
recommended below:
Switch 7 Mounting Height
off “Low < 3.0 m”
on “High > 3.0 m” (*)
(*) Factory Setting.
17.0 Accessories
17.1 Interface Module IF 485B and Installation Software
The installation software is very useful for alignment and signal check
during setup and maintenance. It indicates the amplitudes generated by
wanted as well as unwanted targets and helps setting the gain control
correctly during walk tests and also shows the magnitude of disturbance
signals. The installation software is to be installed on a PC; an interface
module is required to convert RS232/USB to RS485. The information for
installation and signal monitoring is displayed on the screen of the PC.
If more than one detector is connected to the same RS485 communication
bus, each detector must have a different identification number.
The RS485 standard requires a bus topology. To ensure proper
communication, the data bus must be terminated on both ends. The IF
485B features a built-in termination resistor.
The interface module IF 485B is available as an accessory and is pre-
configured and equipped with the necessary connectors to be operated with
any detector of the PRO Series.
The input cable is 5.0 m long and is terminated with a RJ12 connector fitting
into the test socket on the electronic board of the detector.
The connection to the PC’s COM port is with a standard 3.0 m RS232 or
with a 1.8 m USB cable (supplied with the IF 485B).
17.2 Cordless Walk Tester CT 45
The cordless walk tester, CT 45, is an accessory for checking the detector
alignment remotely. During a walk test it indicates a detector alarm with a
beeper and an LED. The walk tester CT 45 consists of a transmitter
(CT 45-T) and a receiver (CT 45-R). For more information, refer to section
8.

Installation Manual Xtralis ADPRO PRO-250H Xtralis ADPRO PRO-250H Installation Manual
8 Doc 14866_01 Doc 14866_01 5
During the initial period of operation it is strongly recommended that walk
tests are repeated and signals monitored under various weather conditions
such as high and low temperatures, wind fog, snow, rain etc. to obtain
comparative data and information on the effects of environmental conditions
on detection and nuisance alarm probabilities for this particular site. Fine-
tuning of the detector based on this data by changing the sensitivity settings
may optimise the performance.
14.0 Internal Heater
A regulated heater connected to the electronic board and powered by the
supply voltage of the PRO-250H prevents condensation on the optical
surfaces and maintains the internal temperature at optimal levels.
15.0 External Sensitivity Adjustment via RS485 Data Bus
If DIP–Switches 1 and 2 are both set to “on”, the detection performance
can be adjusted via the RS485 two way communication port. The range
sensitivity of the PRO-250H can be set to between 75 m and maximum. In
addition to this, the overall sensitivity can be fine adjusted using the
software sensitivity slider.
The external sensitivity adjustment may also be used if overall sensitivity
has to be changed at certain periods of the day or year depending on the
prevailing thermal contrasts. Walk tests in the actual environment will
determine the optimum settings.
16.0 Signal Processing
The sophisticated signal processing ensures optimum performance and
reliability of the detector.
The background noise is sampled and averaged over a large number of
cycles, giving a noise dependent value for the alarm threshold and to start
the adaptive signal shape analysis whenever a certain amplitude is
exceeded.
If the threshold has temporarily been increased by high background noise
or repeated movements in the field of view, the exponential decline of the
threshold level to its original value will take approximately 1… 2 minutes
from the end of the event.
Once the threshold level value has been exceeded, the microprocessor
starts its signal shape analysis routine whereby a number of interdependent
parameters are calculated and analysed.
Only if a signal meets all the predetermined criteria an alarm will be
generated.
If the mounting height is less than 2.5 m, a detection gap at approximately
10 m distance may be observed for fast movements. This is due to the
overlap of the three zones and resulting rejection of simultaneous signals.
7.0 Adaptive Threshold Discrimination (ATD)
The background noise is constantly averaged and used to adjust the
threshold levels for the alarm. This special feature reduces the probability of
nuisance alarms caused by wind, moving vegetation or objects that have a
thermal contrast, although usually weaker than a person.
Each signal exceeding a certain minimum value will activate the ATD and
increase the threshold levels of the corresponding channel, depending on
its strength. Signals generated by a person moving within the specified
speed range, however, are fast enough for detection.
Repeated movement of any kind within the field of view is therefore
activating the ATD, reducing the overall sensitivity. This has to be noted
particularly when walk testing the PRO-250H following installation.
DIP–Switch 3 is used to activate or deactivate the ATD.

(*) Operation of the PRO-250H in this mode is possible but not recommended in
outdoor applications as the nuisance alarm rate could increase significantly as a
result of turbulences.
(**)Factory Setting.
Note: When walk testing the unit, the alarm threshold level will increase as
a result of the signal generated by the target and decrease exponentially in
time after the event. To make sure that original sensitivity is reached, wait
for at least three minutes between each crossing or disable the ATD
function by setting DIP–Switch 3 to “off“.
If the Installation software is used for monitored walk tests and DIP–
Switches 1 and 2 are set to software settings (on – on), the threshold level
can be kept to its nominal value by changing the configuration of the ATD to
“off“ for this test.
Note: DIP–Switch 4 has no function in this detector model.
8.0 Test
When doing a walk test using the CT 45 (refer to section 17.2), in HW mode
DIP–Switch 5 must be set to “on“ or when operating the detector in SW
mode the “test” mode must be set to “on“. After the walk test the “test”
mode must be switched “off“.

Important: The transmitter CT 45-T of the cordless installation tester has to
be placed within the housing with the detector cover closed and securely
tightened. The antenna of the transmitter must be placed straight in the
detector housing.

9.0 Anti Tamper Feature
The PRO-250H is equipped with sophisticated protection against
tampering. It detects misalignment of a detector from its original position,
defined during installation and commissioning.
A change of the detector position generates a permanent alarm until the
detector’s alignment is back in its original position or until the position has
purposely been reset. When using the alarm management with RS485
communication a tamper alarm will be identified separately.
The transistor and/or relay may be configured via software to activate. By
default, the transistor only activates for a tamper.
After the turn-on time of typically 30 seconds from power on, the detector
determines and stores its alignment position (only with the detector cover
closed).
After opening and closing the cover with the unit powered on, the detector
determines its alignment position and stores the position value after five
minutes again without having the detector in permanent alarm state. During
this time the anti tamper sensor can be reset with a power off-on. When
using the PRO software the anti tamper sensor can be reset by means of
setting the tamper reset function in the setting window.
During normal operation, resetting the anti tamper sensor after the
detector’s position has been changed, can be done either remotely with the
PRO program (takes app. 10 seconds) or a power cycle (30 seconds).
Hardware Mode
When operating the detector in the HW mode, the anti vandal function is
activated by setting DIP–Switch 6 to “on“.

Software Mode
Operating the detector in the SW mode, the anti tamper function is
activated by means of setting of the corresponding parameter in the
settings dialog of the PRO software to “on“. By default, the anti-tamper
function is enabled.
Note: DIP–Switch 8 has no function in this detector model.
10.0 LED
The electronic board is fitted with a dual LED, which has a red and green
colour side. This can be monitored during installation while the cover is
open.
• The red LED indicates whether the detector is in alarm state
• The green LED flashing at 2 Hz frequency indicates the detector
ready state.
• During the turn-on time, the red LED is on.
11.0 Alarm Management
The PRO-250H features an alarm management function over RS485
communication. All the detectors connected to the same data bus provide
all the information relevant to an alarm in a two-byte string. For further
information please contact the manufacturer.
12.0 Alarm Time
Alarm time and count per event is determined by the duration of the
detected event and depends on the shape and amplitude of the alarm
signal. Individual alarm pulses have a minimum time of approximately 2.5 s.
13.0 Internal Temperature Compensation
The PRO-250H is detecting radiation differences of a target against its
background. In the course of the day and year the contrast of a person will
vary considerably and affect the signal strength. To compensate for this
contrast variation, the PRO-250H has internal temperature compensation
with maximum sensitivity at approximately 30°C (where the contrast of a
human target is weakest) and gradual reduction at higher and lower
temperatures.
CAUTION: When installing a unit, the internal temperature may take
up to 30 minutes or more to stabilise to the actual
external temperature. Sufficient time should be given to
the PRO-250H to reach the correct internal temperature
and sensitivity before performing walk tests.
