The JA-80PB wireless PIR
motion/glass-break detector
The JA-80PB is a component of Jablotron’s Oasis 80 alarm system. It
consists of two independent detectors which occupy two separate
enrollment addresses in the control panel. The motion detector uses a PIR
sensor. The glass-break detector uses the analysis of air pressure
variations combined with the characteristic sound of glass breaking. The
product is designed for internal use in buildings. The battery-powered
detector communicates via OASIS radio protocol.

Installation
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. Within the detection range of the PIR sensor
avoid the presence of objects rapidly changing in temperature, such as
electrical heaters, gas appliances etc. 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.
Because of its sensitivity to air pressure changes and sounds it should not
be located close to air conditioning or ventilation outlets. There should be
no sources of vibration or audible sounds in the protected area. 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.
Warning: The most frequent cause of false alarms is bad detector-
positioning
Do not arm this detector if there are any people or pets moving within the
protected area.
1. Open the detector cover by pressing the tab and disconnect the
cable to the module located in the front cover.
2. Remove the internal PIR module held by an internal tab.
3. Punch screw holes through the rear plastic cover. At least one
screw should penetrate the tamper-sensitive section.
4. Screw the rear cover to the wall, about 2 metres above the floor
(vertically, with the tab down).
5. Return the PIR module to its original place.
6. 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 in the PIR detector to activate its enrollment.
c. Install a battery in the glass-break detector and then connect its
cable to the PIR module. This will activate its enrollment to the
next vacant address in the control panel. This means that the
glass-break detector enrolls after the PIR does.
d. Exit enrollment mode by pressing “#”
To enroll a detector after having already connected batteries, first
disconnect the batteries, and press and release the tamper sensor to
discharge any remaining charge to ready the device for enrollment. After
installing batteries into the detector, allow two minutes for stabilisation.
During this period the LED is continuously lit.
PIR module DIP switches
NORM / HIGH: selection of immunity to false alarms. The NORM position
combines very good immunity with fast sensor reactions. The HIGH
position gives increased immunity with a slower reaction time and is only
used for problematic installations.
INS / DEL. DEL provides entrance & exit delays for detectors installed in a
building entrance. INS allows the detector to instantly trigger alarm
activation if the control panel is armed. This DIP switch (INS/DEL) only has
an effect if the detector has a natural reaction assigned to its address in
the Oasis control panel. It also has no effect when used with a UC-8x or
AC-8x receiver.
Glass-break module DIP switches
DEL / INS selects the reaction of the control panel if glass-breaking is
detected. DEL provides entrance & exit delays and is recommended for
detectors installed near a building’s entrance door. INS allows the detector
to instantly trigger alarm activation if the control panel is armed. This DIP
switch (INS/DEL) only has an effect if the detector has a natural reaction
assigned to its address in the Oasis control panel. It also has no effect
when used with a UC-8x or AC-8x receiver.
PIR / GBS: This selects whether PIR or glass-break triggering is shown by
the LED. Changing this setting only has an effect during the first 15 minutes
after closing the cover (test mode).
Note: Although both detectors are located in one housing, they do act
independently. Each one has its own address. Each one also has its own
selectable reaction via DIP switches in the detector or in SERVICE mode
on the control panel.

Testing the detector
15 minutes after closing the detector cover, the LED shows PIR or glass-
beak detector triggering according to what was previously selected by the
PIR/GBS DIP switch during test mode. The strength and quality of detector
signals can be measured by the control panel in Service mode.
With the DIP switch in position PIR, short LED flashes indicate the
processing of movement triggering the detector. Long flashes show that
movement detection is being signalled to the control panel.
With the DIP switch in position GBS, the LED flashes very briefly when air
pressure changes occur, e.g. a soft knock on a window. A long flash
indicates triggering by breaking glass and the transmission of a signal to
the control panel.
Testing and adjusting the glass-break sensor:
Using a suitable tool or a hand protected by gloves, one by one, knock
all the windows that should be under the detector’s protection. A
visible deformation of the glass should occur but without any damage.
The deformation of glass causes a change in the air pressure of the
room which makes the LED on the detector flash quickly. The DIP
switch must be in the GBS position.
Sensitivity to air pressure changes can be adjusted by a potentiometer
on the glass-break sensor PCB located inside the front cover of the
detector. Turning clockwise increases sensitivity. Avoid selecting too
high a sensitivity as this can cause a short battery lifetime.
The complete function of the glass-break detector can be tested with a
GBT-212 glass-break simulator. After knocking the glass, this
simulator will automatically generate the characteristic sound of
breaking glass to create the conditions for detector triggering.
If there are any devices in the detector’s protected area generating
sound such as air conditioning, heating, fax machines, refrigerators,
etc., check that they are not triggering alarms by emitting sounds like
breaking glass.
Detection characteristics of the PIR sensor
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.
Side view Top view
The characteristics can be changed by using optional lenses:
JS-7904
Suitable for long corridors. The middle beam covers 20
meters.
JS-7906
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.
JS-7901
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.
5 minute/1 minute PIR sensor sleep time
To save battery energy, the PIR sensor part of the detector switches to
battery-save mode 15 minutes after the cover is closed. During battery-
save mode the PIR sensor 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 PIR sensor ignores any further movement.
After these 5 minutes, the PIR sensor 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. This sleep time has no
effect on the glass-break sensor which is always ready to trigger a
glass-break alarm.
Auxiliary alarm input
There is an input terminal in the
detector which, among other
things, can be used to detect open
doors or windows. Open circuiting
the input has the same effect as
movement in front of the detector
The maximum allowable cable
length to connect a normally-
closed sensor to the terminal is 3
metres. Short circuit these
terminals if the input is not used.
Detection characteristics of the glass-break sensor
The directional response of the glass-break sensor has near spherical
characteristic and it is possible to detect breaking glass up to 9 metres
away as can be seen in the below diagram. The size of glass should be at
least 60 by 60 cm. For smaller sizes the detection range can be shorter.
Only breaking glass forming part of the walls within the protected area can
be detected. All kinds of glass can be protected including windows covered
with unbreakable folio.
Warning: This type of detector is not suited to sensing holes being cut
through glass by glass cutters. For this reason, valuables near
windows should be covered by PIR sensors.

Battery replacement
This detector has two batteries inside whose condition is regularly
checked. If any of the batteries has expired, then the user or installer is
informed. The detector continues to work and each movement in front
of the detector is shown by a brief LED flash. The batteries should be
replaced within two weeks by a qualified technician in SERVICE mode.
After battery replacement the detector needs two minutes to stabilise
during which the LED is permanently lit. After battery replacement test
the functioning of both sensors. 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 from its two addresses in the control panel
before intentional removal.
