JS-20 LARGO,P.I.R. detector
MGD51208
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.
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
•
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).
•
Each detected movement will be indicated by the detector’s LED (if not
disabled)
•
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-7910
. 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.
Lens characteristic diagrams can be seen in documents supplied with
the lens or on the Jablotron website
