GB Infrared Motion Detector
For installation and operation of this unit, please refer to
the diagrams and drawings of these operating instruc-
tions. You will find them on the reverse of the Dutch ver-
sion.
1 Applications
The passive infrared motion detector S-230A has been de-
signed for application in video monitoring systems and alarm
systems. It is suitable for indoor use only. To allow various
applications, the detector is supplied with four interchangeable
Fresnel lenses (wide angle, tele, pet, curtain). The alarm out-
put can be adjusted to NC (normally closed) contact or NO
(normally open) contact. Tampering actions on the unit are
detected by means of an anti-tampering housing contact.
2 Safety Notes
The motion detector corresponds to the directive for electro-
magnetic compatibility 89 / 336 / EEC.
The motion detector is suitable for indoor use only. Protect
it against humidity and heat (admissible ambient tempera-
ture range 0 – 40 °C).
For cleaning only use a dry, soft cloth. Never use chemicals
or water.
Never touch the surface of the sensor [(5) in fig. 7] when the
housing is open, otherwise the sensor might be damaged.
If the motion detector is used for other purposes than orig-
inally intended, if it is not correctly installed or connected or
not repaired in an expert way, no liability for any damage will
be accepted.
If the motion detector is to be put out of operation perma-
nently, take it to a local recycling plant for disposal.
3 Mounting of the Lens
The motion detector is supplied with four different lenses. For
distinction, each lens is provided with a number: See figures
1 to 4 (upper diagram: top view, lower diagram: side view) and
the table at the bottom of this page.
The wide angle lens (No. 1) is installed in the factory. For
mounting a different lens, proceed as follows:
1) Unscrew the unit, remove the front cover.
2) On the inside of the front cover (see fig. 5), the lens (2) and
a fixing frame (1) on top of it are locked into the lens sup-
port (3). First remove the frame, then carefully remove the
lens underneath the frame from the support.
3) Carefully push the selected lens into the support with the
smooth side outwards so that it locks into place under-
neath the two plastic ridges of the support and the protrud-
ing part with the lens number perfectly fits into the recess
of the support.
4) Place the fixing frame over the lens and carefully push it
into the support so that it locks into place.
3.1 Using the curtain lens (lens 4)
According to the fact whether the reflector [(4), fig. 7], situated
above the sensor [(5), fig. 7], is used or whether it is removed,
there are two possibilities of coverage for the curtain lens:
Curtain A: The reflector remains on the PCB. The coverage
area is limited in height (fig. 4 a).
Curtain B: The reflector is removed. The coverage area is
extended in height (fig. 4 b).
To adjust Curtain B, proceed as follows:
1) Release the screw on the right of the PCB [(6), fig. 7] and
remove the PCB from the rear side of the housing.
2) To unlock and remove
the reflector, slightly
squeeze together the
reflector's locking pins
on the rear side of the
PCB with your fingers or
with small pliers and
push them upwards.
3) To protect the sensor against reflections of the compo-
nents on the PCB, place the supplied rubber ring over the
sensor until stop.
Important note for using the curtain lens:
If the front cover is reinstalled after making the connections
and adjustments, it must be installed on the rear side of the
housing, turned by 90° to the right, i. e. for screwing down the
two housing parts use the drill hole [(7), fig. 7].

4 Installation

The motion detector can be installed on an even surface or in
a corner. It should be located in such a way that the person
releasing the alarm is moving across the monitoring zone of
the detector. The minimum mounting height is 2 m (lenses 1,
2, and 4) or 1.3 m (lens 3) above the ground.
Important note concerning the mounting location!
To eliminate the risk of false alarms as far as possible, the
motion detector must not be subjected to draft or great tem-
perature variations. Therefore, it should not be adjusted to win-
dows, outside doors or heat sources such as radiators, ovens,
uncovered incandescent lamps, etc. or placed next to them. In
any case, also avoid direct sunlight on the motion detector.
1) Unscrew the unit, remove the front cover.
2) Release the screw on the right of the PCB [(6), fig. 7] and
remove the PCB from the rear side of the housing.
3) On the rear side of the housing, carefully pierce the prede-
termined breaking point "d " (see fig. 6) for the cable inlet
by means of a suitable tool.
4) From the remaining six predetermined breaking points, se-
lect those two which correspond to the respective mount-
ing location and pierce them by means of a suitable tool:
predetermined breaking points "a" for installation on an
even surface (wall or ceiling)
predetermined breaking points " b" for installation in a
corner (beween two side walls)
predetermined breaking points "c" for installation be-
tween the ceiling and a side wall
5) Pull the connecting cable through the cable inlet and fix the
rear side of the housing with two screws and dowels via
the two drill holes.
Note: Instead of the screws, the motion detector can also be
installed by means of the supplied adhesive strip.
5 Connecting and Adjusting the Motion
Detector
Prior to connecting the detector, switch off the alarm control
panel. For connection and adjustments of the unit see fig. 7.
1) By means of the plug contact " P3 " on the PCB, the alarm
output, i. e. the two central screw terminals of the terminal
strip, can be alternatively adjusted to NO (normally open)
or NC (normally closed):
jumper positioned on one pin only (fig. 7 a):
relay output is "normally open" (NO)
jumper positioned on both pins (fig. 7 b):
relay output is "normally closed " (NC)
2) According to the adjustment of the alarm output, connect
the two central screw terminals " N.O. / N.C. ALARM " to an
NO or NC line of the alarm control panel.
3) Connect the two left screw terminals " N.C. TAMPER " to
the anti-tampering line of the alarm control panel. This line
detects tampering actions on the motion detector: As soon
as someone tries to open the housing, the anti-tampering
contact will open the circuit, and an alarm is triggered.
4) Connect the power supply (9 V to 16 V ) to the two right
screw terminals "+" and "-". The correct polarity must be
observed in any case.
5.1 Adjusting the range
The range of the detector is adjustable by means of the two
scales from 1 to 5 on the PCB. The table below indicates the
recommended scale setting for the desired range.
To adjust the range, displace the PCB vertically upwards or
downwards [if the PCB is mounted, release the screw (6) first]
in such a way that the pointers (8) of both scales are on the
mark of the corresponding scale setting.
Example: In fig. 7 the PCB is positioned in such a way that
the scale setting is "1", i. e. with a mounting height
of 2 m, the maximum range for the wide angle lens
(lens 1) is 5 m, for the telelens (lens 2) 12 m.

1 Wide angle
zone 2

2 Tele
zone 2

4 Curtain
Important! The range depends on the selected mounting
height. If the detector is installed e. g. at a height of 2.5 m,
approx. 10 to 15 % must be added to the range indicated in the
table. On the other hand, if the mounting height is 1.8 m,
approx. 10 to 15 % must be deducted.
5.2 Pulse counter
By means of the plug contact "P2" on the PCB, the motion
detector can be adjusted in such a way that it counts one or
two pulses.
Operating mode "1 pulse"
An alarm is triggered if a person is moving across one of
the monitoring sectors.
To adjust this operating mode, position the jumper on one
pin only of " P2 " (see fig. 7a).
Operating mode " 2 pulses"
An alarm is triggered only if a person is moving across two
of the monitoring sectors (higher protection against false
alarms).
To adjust this operating mode, position the jumper on both
pins of " P2 " (see fig. 7 b).
Note: When using the curtain lens (lens 4), adjust the operat-
ing mode "1 pulse".
6 Functional Test
1) After connecting and adjusting the detector, fix the PCB in
the housing by fastening the screw (6). Replace the front
cover (when using the curtain lens, turn the cover by 90° to
the right) and screw it down.
2) Apply the operating voltage. After approx. 1 minute, the
detector is ready for operation.
3) To test the function of the detector and to check if the
coverage angle and the range have been correctly se-
lected, slowly walk across the monitoring zone. Repeat this
from various directions while observing the LED (9):
If the operating mode "1 pulse" is adjusted, the LED
lights brightly when a movement is detected.
If the operating mode " 2 pulses" is adjusted, the LED
lights dimly when a movement is detected. It does not light
brightly until a second movement is detected.
4) To prevent unauthorized persons from spying out the moni-
toring zone, the LED can be switched off after the func-
tional test. For this purpose, open the front cover (Atten-
tion: With the alarm control panel switched on, an alarm is
triggered via the anti-tampering contact when the housing
is opened!), remove the jumper from plug contact " P1" on
the PCB and position the jumper on one pin only of the
plug contact (see fig. 7a).
