When the setting is complete, it is followed by adjustment of the receiver
unit:
Fig. 5 Setting up using a multimeter
A permanently lit LED on the transmitter/receiver indicates that the beam has
been interrupted (or wrongly adjusted). The better the beam reception, the
longer the break between the LED flashes – see fig. 8, LED 2. When the LED
stops flashing, continue looking for the ideal position indicated by the highest
voltage measured on the voltmeter (see fig. 5). The ideal measured value
should be
higher than 2.4 V
.
Setting up the electronic part of the barrier
Both units are equipped with settings switches. Each barrier has specific
beam modulation so that´s why several barriers can be installed near each
other. The barriers cannot influence each other.
There is a DIP switch on the receiving unit with six switches. It is possible
to set the beam modulation (the setting has to be the same on the receiver
as on its partner transmitter). For beam modulation setting see figure 6. For
examples of installations, see the original manual in the delivery pack. It is
possible to set a 2 minute sleep time after an alarm (beam interruption) in
order to save the batteries. The setting is done by switching switch no. 3 to
the ON position. The auxiliary output is set by DIP no. 4.
Don´t change
this
setting, it ensures the correct triggering of the fault status. DIP switches no. 5
and no. 6 determine the reaction sensitivity. See options for settings in fig. 7.
Note:
If the beam strength is reduced (less than 50%) for more than 20 s,
it triggers a fault and a report is sent to the control panel.

Testing
Perform the barrier test in three places (A, B and C – next to both the units
and in the centre). The setting is completed only if the barrier reacts
successfully in all three positions. You should also check the signal
transmission to the system control panel. Only then is it possible to put back
the unit covers and secure them and then perform the final test.
Fig. 8 Barrier function test
The indication LEDs on the units (fig. 8) have the following functions when
the tamper is unlocked:
Alarm (1)
indicator lights when the beam is interrupted.
Level indicator (2),
the better the beam reception, the longer the break
between the LED flashes.
Low Battery (3)
indicators flash if the batteries in the unit are discharged.
Always replace both (all) batteries at the same time. (SAFT LSH20 lithium
batteries).
Power (4)
indicator- lights when the transmitter unit works.

Replacing the batteries
The detector checks the battery status automatically and if the batteries
are running low, it informs the system. The detector remains fully functional.
The batteries should be replaced as soon as possible (within 1 week). Use
SAFT LSH20 lithium batteries
and always replace all at the same time. If it
is needed to increase the lifetime of the batteries you can add two more
batteries. Then you have 4 batteries in one unit.
