Installation and Maintenance
1 Introduction
The P IR is a highly sensitive Passive Infrared Detector designed for detection outdoors with a wide angle,
volumetric differential field of view. It incorporates 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 in function of 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 RS 485 communication interface module.
2 Mounting and Installation
The mounting structure should be stiff enough and resist to significant deflections in windy conditions. Movement of
the PIR caused by vibrations or other movements will result in swings of the field of view covered by the PIR 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.
The stainless steel bracket is ideally suited for wall mounting (using screws). For pole mounting the original
accessory is available (pole mounting bracket with two strap bands for poles up to 4 – 16 cm in diameter). For
further information please refer to 16.2.
• It is very important that the cover of the PIR is securely tightened. It must be tightened with the two screws to
the point where it cannot be closed further with reasonable force. There will then be hardly any gap between
the cover and the bottom part of the housing (considerably less than 1 mm).
The detectors are fitted with two cable entry assemblies of M16. The nut on the cable entry assembly should be
tightened to clamp the cable in place with reasonable force. If the cable diameter is too small to be held properly,
insulation tape should be wound around the cable to increase the outside diameter to a suitable size.
3 Connecting the PIR
For the definition of the electronic board and terminal block see appendix 19.1.
Alarm Signalling
There are three types of alarm signalling from the P IR:
• one SPST potential-free relay contact
• one open collector transistor output
• an RS 485 two way communication link (see appendix 20 for details)
With the detector in factory setting the relay contact opens and the transistor switches to low resistance on alarm.
Output logic and function can be changed using the installation software.
During turn-on time the relay output is in alarm state!
Cover Switch
To detect attempts to open the detector, a switch is fitted for the cover. Its contact opens when the cover is opened.

4 Field of View
The P IR has a wide angle, volumetric field of view with differential detection areas. The nominal ranges refer to the
table below.
Definition PIR-018 PIR018H
Nominal Range 50 m (165 feet) 60 m (200 feet)
Width at Nom. Range 3.3 m (11 feet) 3.9 m (13 feet)
5 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 PIR should be aligned so that a natural or artificial background at the end of the
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.
Alignment can be done visually by looking along the grove on the top of the detector. This line of sight cor responds
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 wanted range.
Typical vertical alignment for a required detection up to nominal range.
The PIR 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 (see Fig. 1 below).

Typical horizontal alignment
Horizontal alignment should be done in a way to avoid unwanted signals being generated by tar gets (branches,
bushes, fences) likely to be moved by wind (see Fig. 2 below). Movement within the field of view will reduce the
sensitivity of the PIR by increasing the alarm threshold level and may lead to un wanted alarms.

Note: The width of the zone at ground level near the detector is in the order of 1.6 m (5.5 ft) edge to
edge when the detector is mounted in 4 m (13 ft) height. This means that special care has to be
taken when mounting a detector onto a wall and aiming along the wall in order not to pick up
disturbances caused by air turbulences along the wall.
