JS-20
„LARGO“
P.I.R. detector
This P.I.R. motion detector is
used to protect interiors. It
detects any movement of
objects with a temperature close
to that of the human body.
The signal from the sensor is
electronically analyzed. This
ensures that the detector
provides excellent sensitivity
and at the same time false
alarms are basically eliminated.
The detection analysis rate can
be adjusted to increase its
immunity if the JS-20 is installed
in a problematic location.
The standard lens in the
detector can be replaced with an
optional corridor or pet immune
lens. Extra terminals (GBS) can
be used to facilitate wiring of the
detector
.
The JS-20 distinguishes itself
with excellent RF immunity.
It can be mounted on a flat wall
or in a corner.

Environment
II. – general indoor, (EN 50131-1)
Operating temperatures
-10 to +55 °C
Security level
grade 2, EN 50131-1
Complies with the essential requirements of: 89/336/EC EMC Directive -
Protection concerning electromagnetic compatibility when is used for its
intended purpose. Original of the conformity assessment can be

, section Technical support.
Installation
This detector is designed for indoor applications. It can be mounted on
a flat wall or in a corner. Do not place the detector close to any
heating/cooling vents or near any other object that often change
temperature. The detector must have an unobstructed view of the
protected area.
1.
Open the cover of the detector
(press in the plastic tab on the bottom
part of the detector’s housing with a screwdriver).
2.
Remove the PCB
by pressing the flexible tab inside the housing.
3.
Punch through the pre-formed holes
for cables and screws.
4.
Attach the housing to the wall
(2.5 meters above the floor).
5.
Return the PCB into the rear housing
and connect the cable wires to
the terminals.
6.
Attach the cover
.
Note:
Avoiding touching or scratching the PIR sensor!

Jumpers
LED
the LED indicator can be disabled by opening this jumper
DETECTION
by opening this jumper you can set a higher rate of analysis
and increase the immunity of the detector. This setting is
suitable for problematic locations with sudden temperatures
changes or electromagnetic interference. Reaction of the
detector will be slightly slower in this setting.
Detector testing
x
After switching on the power, wait for 1 minute. During this period the
detector initializes and stabilizes its parameters (LED will be on if not
disabled).
x
Each detected movement will be indicated by the detector’s LED (if
not disabled)
x
Confirm that the detector covers the protected area as you expected.
Lenses
Standard lens
that is supplied with the JS-20 Largo detector covers an
area of 120 degrees / 12 meters.
For special applications other lenses can be used. Optional lenses for
long corridors and areas with small animals are supplied separately.
The Pet lens
is marked
JS-7906
. This lens prevents animals
smaller then 40 cm to be detected by the detector. The working range of
this lens is reduced to 7 meters. It is recommended to test this lens
carefully with the animal when installing the system, in order to prevent
false alarms.

The Corridor lens
is marked
JS-7904
. The working range of this
lens is 25 meters long and only 3 meters wide. It is recommended to test
the detector’s sensitivity carefully when installing it into a corridor.

The curtain lens
is marked
JS-7902
. By using this lens the PIR
detector's working range is restricted to a "curtain". After using this lens, it
is for example possible to secure part of a room etc. During the
installation it is necessary to test the working range very carefully.
