JA-83P wireless PIR motion detector 2 PTS1_MLK510xx
The JA-83P wireless PIR motion detector
The JA-83P is a component of Jablotron’s OASiS alarm system. It is designed
to detect human body movement inside buildings. The detection pattern can
be modified by optional lenses. Detector immunity has two selectable levels.
The battery-powered detector communicates via OASiS radio protocol.
Installation shall only be undertaken by technicians holding a certificate issued
by an authorized distributor. The detector can be installed on a flat wall or in
the corner of a room. Avoid objects rapidly changing in temperature, such as
electrical heaters, gas appliances etc. being positioned within its detection
area. Moving objects with a temperature close to that of humans such as
curtains moving above a radiator, and pets should also be avoided. Detectors
should not face windows or spotlights or be near fast-moving air e.g. near
ventilation fans or open windows or doors. There should also be no obstacles
blocking the detector’s “view” of the protected area. Keep the detector away
from metal objects which could interfere with radio communication.
1. Open the detector cover
by pressing the tab (5).
Avoid touching the internal
PIR element or damaging
the antenna.
2. Remove the PCB which is
held by an internal tab (3).
3. Punch screw holes
through the rear plastic
cover – for a flat wall (1) or
for a 45° (corner)
installation (4)
4. At least one screw should
penetrate the tamper-
sensitive section (2).
5. Screw the rear cover onto the wall, about 2.5 metres above the floor
(vertically, with the tab down).
6. Return the PCB to its original place.
7. Leave the battery disconnected and the cover open and then follow
the control panel or receiver manual. The basics of enrollment are:
a. Enter enrollment mode on the control panel by keying in “1” in
Service mode.
b. Install a battery into the detector to activate enrollment.
c. Exit enrollment mode by pressing “#”
8. Close the cover and the tab can be finally fixed using the supplied screw.
To enroll a detector after having already connected a battery, first
disconnect the battery, and press and release the tamper sensor (11) to
discharge any remaining charge to ready the device for enrollment. After
installing a battery into the detector, allow three minutes for stabilisation.
During this period the LED is continuously lit.
The detector can also be enrolled by entering its serial number – the last
eight digits of the bar code (7)
To comply with EN-50131-2-2 the battery must be secured in the holder
using the supplied clip and the front cover tap must be fixed using the
supplied screw.
DIP switches
DIP switch 1 Selection of
immunity to false alarms.
The NORM (OFF) position
combines very good
immunity with fast sensor
reactions. The HIGH (ON)
position gives increased
immunity with a slower
reaction time and is only
used for problematic
The most frequent cause of false alarms is bad detector positioning.
DIP switch 2 The DEL (OFF) position provides entrance & exit delays for
detectors installed in a building entrance. The INS (ON) position allows the
detector to instantly trigger alarm activation if the control panel is armed. This
setting only has an effect if the detector has a natural reaction assigned to it
in the Oasis control panel. It also has no effect when used with a UC-8x or AC-
8x receiver.
Testing the detector
15 minutes after closing the detector cover, the indicator shows detector
activation. The strength and quality of detector signals can be measured by the
control panel in Service mode.
5 minutes / 1 minute sleep time
To save battery energy, the detector switches to battery-save mode 15 minutes
after its cover is closed. During battery-save mode the detector still always watches
out for movement. The first movement detected is then signalled to the control
panel instantly, and for the next 5 minutes the detector ignores any further
movement. After these 5 minutes, the detector then returns to watching out for
movement until re-triggered. The sleep time can be shortened to 1 minute by
pressing the tamper switch during battery installation. Not pressing the tamper
switch gives a sleep time of 5 minutes.
Battery replacement
The detector monitors its battery voltage and if too low, a transmission is sent to
the control panel to inform the installer or user. The detector continues to function
and shows each detected movement with a flash of its LED. Battery replacement
should not be delayed by more than two weeks. This should be done by a
qualified technician with the control panel in Service mode.
After battery replacement, the detector needs about 3 minutes to stabilise
during which its LED lights continuously. After the LED has stopped
indicating, test the detector’s functioning.
If a partly discharged battery is inserted then the LED starts flashing for one
minute. Then the detector will work but the Lo Bat signal will be sent to the
control panel.
Expired batteries should not be thrown into the garbage, but disposed of
according to local regulations.
Removing the detector from the system
If a detector is removed, the control panel announces the removal. The
detector has to be deleted in the control panel before intentional removal.
Detection characteristics
The default lens supplied covers an angle of 120° and a distance of 12 metres.
The area is covered by three beams as shown in the following picture.
Top view
Side view
The characteristics can be changed by using optional lenses:
JS-7904 Suitable for long corridors. The middle beam covers 20 meters.
Only employs an upper beam with a 120° angle and a 12 metre
range. Ignoring the floor eliminates the effect of the movement of
small pets.
Has a vertical beam forming a wall-like detection barrier which
triggers the detector if someone walks through it.
Note: After changing the lens, test that the desired area is protected. Incorrect installation of the
lens can disable detection.
