JA-120PW Bus combined PIR and MW motion detector
JA-120PW Bus dual PIR and MW motion detector
1 / 2
MML51104
The JA-120PW is a bus 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
provides great immunity against false alarms. The detector works
like a classic PIR detector, however when PIR detects movement 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 takes one position in the system
and should be installed by a trained technician with a valid
certificate issued by an authorised distributor.
Installation
Given the principle and detection characteristics of the MW
detector, the best results can be achieved when the detector is
installed in a corner of a room. No moving objects (e.g. waving
curtains above a radiator) or animals should be in the detector’s
field of vision. There should be no obstacles in front of the detector
which could obstruct its view and it should not be installed near
metal objects (they could affect the MW field). It is also not possible
to install two and more detectors in an area where MW transmitters
could affect each other.

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) of the MW part.
3. Punch through the holes for the screws and the cable in the plastic
base. The recommended detector installation height is 2.5 m 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).
Always switch the power off before connecting
the detector to the system bus.
5. Put the PCB back and connect the bus cable to the terminals
(1).
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. In the next window, click on “
Scan/add new BUS devices”,
select the detector from the list and double-click on it to confirm
your selection. You can also enrol the device by pressing the
tamper contact in the detector (6). The yellow LED light will
shut down after successful enrollment.
7. Close the detector cover.
Note:
-
The detector can also be enrolled into the system by entering its
serial number (5) in the F-Link program. The serial number is on
a label with a bar code which is placed inside the detector (3).
All numbers shall be entered (example: 1400-00-0000-0001).
-
If you want to remove the detector from the system, delete it from
its position in the control panel.
Detector internal settings
The detector properties can be set in the
Devices
tab of the
F-Link software. Use the
Internal settings
button, on the same
position as the detector, to open a dialog window where you can
set following (factory settings are marked with*):
Activation indicated by LED:
disable* / enable
movement indication
by a red LED. Indication always works in Service mode
PIR immunity level:
determines a level of immunity to false alarms.
Standard*
combines basic immunity with a fast sensor reaction.
Increased
has stronger immunity with a slower reaction time.
MW immunity level:
determines the level of analysis performed by
the MW motion detector.
Standard*
combines basic immunity with
a fast sensor reaction.
Increased
has stronger immunity and
provides a slower reaction time.
Detector Testing
Check the functioning of both sensors using a jumper (8) when
the control panel is in
Service mode. Warning:
Confirmation of
activation by the MW detector can’t be carried out when the control
panel is unset therefore it’s not possible to fully test its function and
configuration.
The PIR detector
is equipped with a 110°/12m lens. Coverage –
see Fig 2. Check the coverage with the jumper (8) in the
“PIR”
position. Movement is indicated by a red LED.
Fig 2: Coverage characteristics can be changed by using an alternative lens:
JS-7904
Designed for long corridors - with a working range of up
to 20m
Increased immunity cannot be used with this lens!
JS-7910
Equipped only with the upper beam covering 120
degrees / 12 m and doesn’t cover the floor (can ignore
the movement of small pets on the floor)
JS-7902
Vertical curtain – it does not cover an area but creates a
detection wall (can be used to create a barrier and
report its breach)
After changing a lens, it’s necessary to test
whether the detector sufficiently covers the area.
The MW detector
reacts to movement from in a 1 m to 15 m
range. The detection range is set by a trimmer (10). In some cases,
the detector can detect movement of non-metal materials behind
fixed obstacles (behind a thin wall, a door, glass, flowing water in
plastic pipes etc.).
It is recommended to set the MW detection range the way
it won’t exceed the field of view of PIR. Testing is carried out by
placing the jumper (8) in the MW position. MW activation
is indicated by a red LED. Given the principle of MW, its coverage
characteristics may significantly differ depending on a size, shape
and facilities of the room in which the detector has been installed.
Especially regarding metal surfaces which cause reflection
or shielding of the signal generated by MW.
During installation, it’s always necessary to test
whether the detector sufficiently covers the area.
