Bosch IR270TLSNi/RB Installation Seite 3

H The detector reacts most sensitively to movement which proceed at right
angles to the coverage zones (the direction of the arrow in figures 1 and 2).
H The detector's coverage area is limited by any solid objects.
H The detector is designed to achieve optimal response sensitivity and a high
level of false alarm suppression. Nevertheless, you are recommended to
take note of the following points (see also figure 10):
− Do not direct the zones at sources of heat or cold, nor at points subject to
strong sunlight or fast changes in temperatures and humidity.
− In the antimask range (0.5m), prevent intensive movement in Real Time
above doors and wardrobes.
− Direct the zones towards uniform references. Zones which are directed
towards heaters (including floor heating equipment) can reduce the prob-
ability of detection of movement.
− If it is impossible to avoid positioning the detector above heaters, you
must keep them at a minimum distance of 1.50m away!
H The integrated breakage/removal contact and the «real time» antimask sur-
veillance system mean that security against tampering satisfies the highest
requirements. What is more, all the functions of the entire detector (includ-
ing the detection sensors) are constantly monitored.
Installation
The detector is intended for use in inside rooms.
Do not remove the printed circuit board from the detector. There is a dan-
ger that it may be damaged!
1. Open the detector (figure 3).
2. Mount the detector on a stable vertical surface.
− Select the height (h) above the floor according to figure 1 or 2.
− Corner mounting and 45° installation (right / left) are possible without any
accessories (see figure 4A).
− Detector must be inclined at an angle of 2° when mounting above 3m in or-
der to detect crawling intruders and to ensure the detection range (see fig-
ure 4B).
− The cable is introduced through one of the knock-out points A (see figure 5).
3. Wire the connections as shown in figure 7.
4. For strain relief on the connection cable, pierce the lug B (figure 5) and fix
the cable with a cable cleat.
5. Select the desired settings as shown in the section on "Programming".
6. Replace the cover, screw it down with the screw provided, and close the
screw cover (figure 3).
Detector breakage/removal monitoring Figure 6
If the detector is forcibly removed from the mounting surface, a sabotage
alarm is triggered.
For this, the detector base must be secured with an additional screw.
Functions
Detector function monitoring (self-test)
A self-test is always carried out when the supply voltage is applied. The detec-
tor is also equipped with a periodic self-test.
A malfunction (such as a sensor failure) is indicated as a disturbance and with
walktest ON the red LED is flashing.
Antimask surveillance
When masking is performed which restrict the motion detection, an antimask
signal is outputted, and during walktest, the masking indicator (flashing red
LED) is activated.
To ensure reliability of operation, detector covers must be replaced if they
have been sprayed. Cleaning them is not enough.
Sensitivity of antimasking surveillance
− Standard
Recommended setting to detect masking.
− High
This setting enables faster and more sensitive masking detection for very
high risks.
Depending on the masking material, the range of the antimask surveil-
lance is approximately 0.20m.
Antimask surveillance function
− Real time
The antimask signal follows the state of the detector. Masking will only be
indicated as long as the detector is masked. This is the setting recom-
mended by the manufacturer.
− Latch
Once the antimask signal is activated, it is retained (stored) on self-hold until
it is reset by carrying out an antimask surveillance reset.
Antimask surveillance reset
− Variant1 via LSN−Bus
With masking present, switch over to walktest ON:
− Remove the masking and trigger the motion alarm;
− Switch back to unset, and the antimask surveillance will then be re-initial-
ised.
− Variant 2
Restart due to voltage cut.
The detection area must be checked after every reset or restart.

Parameterization
The detector is parameterized using the corresponding LSN control unit para-
meterization software. Detection sensitivity can be set according to the follow-
ing table.

Commissioning
1. After commissioning the detector linked to the LSN, wait for at least 1 min-
ute until the detector is ready for operation.
2. Activate the walktest in order to test the coverage area.
3. Cross the area monitored in an upright position at about 1 step per second
in the direction of the arrow (figure 1 or 2) and stand still. Alarm evaluation (dis-
play) can take up to 3 seconds!
Upon alarm display, wait until the LED has extinguished again. Only then re-
peat this procedure throughout the entire coverage area.
The detector must trigger an alarm even when you cross the zones at the
edge of the coverage area.
Sealing the detector
Figure 3
If sealing of the detector is prescribed, apply an adhesive seal over the gap
between the base of the detector and the cover.
Maintenance
Check the function of the detector regularly (at least once per year) − carry out
a walktest, check for dirt and inspect the fixture.
Troubleshooting
Detector does not react
− Check LSN voltage and polarity.
− Check whether the mirror is inserted.
Permanent or temporary alarm
− Track down any sources of alarm in the coverage area, remove sources of
alarm.
− Check evaluation mode.
− Change the position of the detector.
Insufficient range
− Check the mounting height and inclination of the detector (fig. 1 or 2).
− Walk at right angles to the coverage (active) area!
− Check the IR window for soiling.
No Antimask signal
− Check the parameterization.
− Carry out an antimask surveillance reset and check the coverage area.
− Change detector
Permanent Antimask signal
− Is the detector totally or partially masked? Remove masking.
− Carry out an antimask surveillance reset and check the coverage area.
− Change detector
Options
Curtain mirror IRS272 Figure 2
The IRS272 curtain mirror has overlapping active zones forming a monitored
area to provide secure monitoring against intrusion. At installation heights
above 3m, mount the detector with a downward inclination of 2°.
Changing the mirror:
Remove the wide-angle mirror from the cover using a No. 1 screwdriver (Fig.
8) and replace it with an IRS272 curtain mirror.
H Use the sensitivity settings «High values», «Standard» or «Increased sta-
bility».
Check the mirror for soiling and damage. Do not touch the pyrosensor!
Mounting bracket IRUM20, IRUM30 Figure 9
The mounting brackets IRUM20 (wall-mounting) and IRUM30 (ceiling mount-
ing) enable the detector to be rotated through ±45° and tilted through
+10°/–15°.
H The monitored zone can differ from that shown in Fig. 1 or 2, depending on
local conditions and the setting of the mounting bracket.
