IS404: Curtain detection, range 120m.
IS404H: Curtain detection,with heating,
range 150m.
Installation
Coverage zone (Fig. 1)
The detector reacts to fast and slow movements
of an intruder within the specified environmental
conditions. The detection capacity is, however,
reduced where there is only a slight temperature
difference between the intruder and environ-
ment or where weather conditions are extreme.
The reaction of the detector is most sensitive to
movements which are transverse to the cover-
age 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 ani-
mals must be prevented, e.g. by a fence.
For installations where the range of a detector
is not sufficient, subdivide the area to be moni-
tored into sections covered by several detec-
tors.
Note that the masking of the coverage zone
is not monitored.
Mounting (Fig.2)
The detector is to be mounted 2.5m to 4.0m
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 other-
wise condensation can form within the de-
tector.
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 limi-
ted 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 ar-
tificial background at the end of the range termi-
nates 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.
Wiring (Fig. 5)
The diagram shows the terminal block connec-
tions.
Programming
Sensitivity
The various settings of the IS404 are made by
means of multiple DIP−Switches on the printed
circuit board.
DIP1−DIP2 Sensitivity
IS404 IS404H DIP 1
60m 75m OFF
84m 105m OFF
Max. Max. ON
Software Software ON
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 rec-
ommended to reduce the range setting to re-
duce nuisance alarms.

Application guidelines

Mounting height
The IS404 is designed for mounting at heights
between 2.5 and 4.0 m above ground. The DIP −
Switch 4 is used to set the relative sensitivity of
all detection zones in function of the mounting
height as recommended below:
DIP4 Mounting Height
Low <3.0m
High >3.0m
If the mounting height is less than 2.5 m, a detec-
tion gap at app. 10 m distance may be observed
for fast movements. This is due to the overlap of
the three zones and resulting rejection of simul-
taneous signals.
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 prob-
ability of nuisance alarms caused by wind, mov-
ing vegetation or objects that have a thermal
contrast although usually weaker than a person.

ATD OFF
ATD ON
Internal Heater (IS404H only)
A regulated heater connected to the electronic
board and powered by the supply voltage of the
IS404H prevents the optical surfaces from fog-
ging or frosting and maintains the internal tem-
perature at optimal levels.
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 OFF
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 de-
tector housing.
Anti Vandal Function
The IS404/IS404H is equipped with a sophisti-
cated protection against vandalism. These de-
tectors can sense certain changes of their align-
ment 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, the detector determines its align-
ment position and stores the position value 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 (walk test), cleanli-
ness 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.
OFF
− After extreme weather conditions (storm,
ON
snowstorm, hail etc.), check the detector for
damage. Remove snow or dust from the detec-
tor window.
Accessories
Interface Module ISIF485B and Installation Soft-
ware
The Installation Software is very useful for align-
ment and signal check during setting up and rou-
tine maintenance. It will indicate the amplitudes
generated by wanted as well as unwanted tar-
gets and help setting the gain 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
OFF
information for installation and signal monitoring
ON
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 data 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.
