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 observe EN 50131-2-2 the tab must be secured by the supplied screw.

 

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.
