PIR Motion Detector
GB
Please read these operating instructions carefully
prior to installation and keep them for later reference.
1 Applications
The motion detector PIR-990 (passive infrared) is
specially designed for applications in alarm systems
and video surveillance systems. When a movement is
recognized, the alarm contact will open or close
(selectable). An integrated 3.9 kΩ resistor can be used
for terminating an alarm loop. The sensitivity is
adjustable in such a way that no alarm will be trig-
gered when pets are passing the surveillance zone
(pet immunity). The detector is protected by an anti-
tamper contact (7) which will notify the alarm control
panel when the housing is opened.
2 Important Notes
This unit corresponds to all required directives of the
EU and is therefore marked with
The unit is suitable for indoor use only. Protect it
G
against dripping water and splash water, high air hu-
midity, and heat (admissible ambient temperature
range –10 °C to +50 °C).
For cleaning only use a dry, soft cloth; never use
G
water or chemicals.
Never touch the surface of the IR sensor (8) when
G
the housing is open; the sensor may be damaged.
No guarantee claims for the unit and no liability for
G
any resulting personal damage or material damage
will be accepted if the unit is used for other purposes
than originally intended, if it is not correctly installed,
or if it is not repaired in an expert way.
If the unit is to be put out of operation defini-
tively, take it to a local recycling plant for a
disposal which is not harmful to the environ-
ment.
3 Mounting
The recommended mounting height is 2 m to 3 m.
G
The mounting place should not be exposed to
G
vibration, direct sunlight or draughts and not be
close to heat sources (e. g. radiators).
Choose a mounting place where the person trig-
G
gering the alarm will move at right angles to the
lens (2).
1) Remove the screw (3) and open the housing.
2) The motion detector can directly be mounted flat to
the wall, in a corner of the room or via the movable
bracket BR-990 available as an accessory. For
fixing the detector to the bracket BR-990, use the
two holes (4). Drill open other knockout holes on
the rear part of the housing which will be required
for fixing and for cable entry. To allow access to the
knockout holes, slightly push the latch (9) to the
right and remove the PCB, if required.
3) Lead the connection cables thought the hole
selected and, if necessary, through the bracket into
the housing. Then screw the rear side of the
detector to the bracket or to the wall.
4) Reinsert the PCB, if required, and lock into place.
5) When the mounting bracket is used, screw it to the
wall or ceiling and align the motion detector to the
surveillance zone.

4 Connection to the Alarm Control Panel
First set the alarm control panel out of operation to
ensure that no alarm will be triggered. Then connect
the detector via the screw terminals (6):
1) Connect the two terminals TAMPER to the anti-
tamper loop of the alarm control panel (in series
with further anti-tamper contacts).
2) Connect the terminals COM and NC for the alarm
loop to the corresponding connections of the alarm
control panel. For the last detector of an alarm loop,
the internal 3.9 kΩ resistor can be used instead of
an external terminating resistor (see specifications
of the alarm control panel). In this case, connect the
terminals COM and 3.9k instead.
A terminating resistor will define the quiescent
current for monitoring the line. In case of a devia-
tion, the alarm control panel will be able to trigger an
alarm.
3) Connect the voltage supply (9 – 16 V ) to the ter-
minals POWER (polarity as desired), but do not
.
switch it on yet.
5 Adjustments and Functional Test
1) The lens (2) will divide the area under surveillance
into 64 zones. Use the jumper J1 (11) to define
whether an alarm will already be triggered with
movement detected in 2 zones or only after move-
ment detected in 4 zones.
To prevent alarm triggering by small animals (up
to approx. 15 kg), rearrange the jumper J2 (11) from
NORMAL to HARSH.
2) The control VR1 (10) allows to adjust the sensitivity
and thus the range of the sensor. Set the control to
mid-position first, then adjust it after the functional
test, if required.
3) Use the jumper J3 (11) to define whether the alarm
contact will act as an NC (normally closed) or NO
(normally open) contact (
control panel).
4) For a functional check, close the detector with the
housing cover and switch on the power supply.
After approx. 30 s, the LED (1, 5) will stop flashing
and the detector is ready for operation.
5) Walk across the surveillance zone in different
directions while observing the LED which will light
up when a movement is recognized.
6) Finally perform a functional test when the alarm
control panel is armed.
