IS390: Volumetric detection, range 21 m.
IS390H: Effective volumetric detection,
range 27 m.
Installation

• The
detector
reacts
to
movements of an intruder within the specified
environmental
conditions.
capacity is, however, reduced where there is
only a slight temperature difference between
the intruder and environment or where weather
conditions are extreme.
• The reaction of the detector is most sensitive to
movements which are transverse to the
coverage zone.
• The coverage zone is limited by walls and
other objects. The following points shall be
noted to obtain optimum sensitivity and reduce
false alarms.
−Align the coverage zone so that it is bounded
at the end by a reference which is as uniform
as possible (floor, wall).
−Align the detector so that a potential intruder
has to pass through the complete coverage
zone.
−There should be no large objects within the
coverage zone, which, for instance, could
move considerably due to wind gusts (large
branches, bushes, high grass).
−The inadvertent intrusion of people and
animals must be prevented, e.g. by a fence.
• For installations where the range of a detector
is not sufficient, subdivide the area to be
monitored into sections covered by several
detectors.
Note that the masking of the
coverage zone is not monitored.
Mounting (Fig.2)
The detector is to be mounted 2.5 m to 4.0 m
above the ground
−either by screwing to a stable surface
or
−strapping to a stable pole.
The cable inlets must not be changed.
Do not seal the cable inlets because

If the cable diameter is too small,
reinforce the cable using insulating
tape.
Alignment of detector
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 detector should be aligned so
that a natural or artificial background at the end
of the range terminates the field of view.
For details refer to fig. 3
The monitored area must then be
checked by a walk test. Refer to
"Walk test" section.

Programming
Sensitivity
The various settings of the IS390 are made by
means of multiple DIP−Switches on the printed
circuit board.

The 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.

Application guidelines
Adaptive threshold decoding (ATD)
The background noise is constantly averaged
and used to adjust the threshold levels for the
alarm. This special feature is reducing the
probability of nuisance alarms caused by wind,
fast
and
slow
moving vegetation or objects that have a thermal
contrast although usually weaker than a person.

IS390H
Unlike the IS390, the H version offers a 25%
greater effective region, an optimised infrared
filter through the silicon window and controlled
heating which prevents the lenses from fogging
up or freezing.
Walk test
Doing walk test using the ISWT41, in HW mode
the DIP−Switch 5 needs to be set to 'on'. After
the walk test, the 'test' mode needs to be
switched 'off'.
DIP5 Walk Test

Test ON
Important: The transmitter ISWT41−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 needs to be placed straight in the
detector housing.
Anti Vandal Function

These detectors can sense certain changes of
their alignment from the original position as set
during the installation. A change of the detectors
alignment generates a permanent alarm until the
detectors alignment is back in its original position
or until the position has purposely been reset.
After the turn−on time of typ. 60 seconds from
power on, the detector determines and stores its
alignment position (only with detector cover
closed).
After opening and closing the cover with the unit
powered
on,

after 5 minutes again without having the detector
in permanent alarm state.
The anti vandal sensor can be reset with a
power off−on (60 seconds).

Maintenance
Check the detector regularly (at least twice a
year)
for
correct
functioning
cleanliness and security of attachment.
−Clean the detector window only with a soft
cloth. Do not use solvents.
−Check the inside of the detector for humidity
and correct sealing of the cover.
−After
extreme
weather
snowstorm, hail etc.), check the detector for
damage. Remove snow or dust from the
detector window.

amplitudes generated by wanted as well as
unwanted targets and help setting the sensitivity
control correctly during walk tests and also show
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 needs to have a different
address (ID) The RS485 standard requires a bus
topology. To ensure proper communication, the
dataline must be terminated on both ends. The
ISIF485B features a built−in termination resistor.
The input cable is 5.0m long and is terminated
with a RJ12 connector fitting into the test socket
on the electronic board of the detector.
