JA-120PW Bus combined PIR and MW motion detector
The JA-120PW is a component of the JABLOTRON 100 system.
It is used for the detection of human movement in building interiors.
The combination of PIR and microwave (MW) detection gives very
good protection against false alarms. When some movement is
detected by the PIR detector in a guarded place, the MW part is
activated and confirms the previous PIR activation. Only then an
alarm is triggered and is sent to the control panel. The detector
should be installed by a trained technician with a valid certificate
issued by an authorised distributor.
Installation
The detector can be installed onto a wall or in a corner of the
room. There should be no objects in motion (for example: curtains
above a heater) and no animals. There should be no obstacles in
front of the detector which might obstruct its view and it should not
be installed near metal objects (they could shield the MW field).
1. Open the detector cover by pushing the tab (7). Avoid touching the
PIR sensor inside (5) – you could damage it.
2. Take out the PCB – it is held by tabs (4). It is not necessary to
unplug the connector (2) for the MW part.
3. Punch through the holes for the screws and the cable in the plastic
base. The recommended detector installation height is 2.5m above
the floor.
4. Insert the bus cable and attach the plastic base to the wall using
screws (vertically, with the cover tab (7) facing downwards).
When connecting the detector to the system
bus, always switch the power off.
5. Put the PCB back and connect the bus cable to the terminals (1).
Testing the detector
Checks the function of both sensors using jumper (8) in service
mode. The jumper only works in service mode.
The PIR detector is equipped with a 110°/12m lens. Coverage –
see the next figure. Check the coverage with the jumper (8) in the
PIR position. Movement is indicated by a red LED.
The properties can be changed by using an alternative lens:
Designed for long corridors – with a working range of up
JS-7904
to 20m
Increased immunity cannot be used with this lens!
Equipped only with the upper beam covering 120
JS-7910
degrees / 12m and not covering the floor (can ignore
the movement of small pets on the floor)
Vertical curtain – it does not cover an area but creates a
JS-7902
Note: with a different lens, test whether the detector covers the area
correctly (a wrongly installed lens can cause detection errors).
detection wall (can be used to create a barrier and
report its breach)
The MW detector reacts to movement from a 1 m to 20 m range.
The detection range is set by a trimmer (10). This detector can
detect the movement of non-metal substances behind fixed
obstacles (behind a wall, flowing water in plastic pipes etc). It is
recommended to set the MW detection range to the same range as
the PIR detection range. Check the coverage with the jumper (8) in
the MW position. Movement is indicated by a red LED.

6. Proceed according to the control panel installation manual. Basic
procedure:
a. When the device is powered, the yellow LED starts flashing
repeatedly to indicate that the module has not been
enrolled into the system.
b. Go to the F-Link software, select the required position in
the Devices tab and launch enrollment mode by clicking on
the Enroll button.
c. Press the tamper contact in the detector (6) – the detector
is thus enrolled and the yellow LED indicator goes off.
7. Close the detector cover.
Detector internal settings
The detector properties can be set in the Devices tab of the
F-Link software. When at the detector position, use the Internal
settings button to open a dialog window where you can set:
Activation indicated by LED: disable* / enable movement indication
by a red LED. In service mode indication always works.
PIR immunity level: selection of immunity to false alarms.
Standard * combines very good immunity with fast sensor reactions
Increased is higher immunity with a slower reaction time and is only
used for problematic installations.
MW switching: determines the level of analysis performed by the
MW motion detector. Standard * combines very good immunity with
fast sensor reactions. Increased is higher immunity and provides a
slower reaction time.

After coverage testing of the PIR/MW parts of the
detector, disconnect* the jumper completely, then the
detector will react to the activation of both detectors.
