Fig. 5 Setting up the optical part
When the setting is complete, it is followed by another step – adjustment
of the receiver unit:

A permanently lit LED on the right indicates that the beam has been
interrupted (or wrongly adjusted). The better the beam reception, the
longer the breaks between the LED flashes. When the LED stops
flashing, continue looking for the ideal position indicated by the highest
voltage measured on the voltmeter.
Setting up the electronic part of the barrier
Both units are equipped with setting switches. The switch located on the side
of the units (on the optical part) allows barrier beam modulation frequency
adjustment from 1 to 4. This setting is useful only for a combination of
multiple JA-80IR barriers where a problem with interference might appear.
For more information see the original user manual or contact the
JABLOTRON ALARMS technical support service.
There is a DIP switch with five switches. The first two positions are used to
set the reaction time to an interruption of the beam. The shorter the time, the
more precise the interruption detection, but also the greater the susceptibility
to false alarms during worsened optical conditions (snow, fog, ...)

Fig. 6 Reaction time setting
It is possible to set a 2-minute sleep time after an alarm (beam
interruption) in order to save batteries. This setting is done by switching
switch no. 3 (receiver unit), or no. 1 (transmitter unit), as the case may
be, to the ON position. Switches 4 and 5 (receiver unit), or better 2 and
3 (transmitter unit) are set as a default and you should leave them in the
ON position for the correct functioning of the device.

Both batteries
(SAFT LSH20 lithium batteries)
should always be
replaced at the same time.

Fig. 8 Barrier function test
Perform a barrier test in three places (A B and C). 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.
Checking the status of and replacing batteries
The detector checks battery status automatically and if the batteries are
running low, it informs the system that they need replacing. The detector
remains fully functional. The batteries should be changed as soon as
possible (within 1 week). Use
SAFT LSH20 batteries exclusively
and
always replace both at the same time.
