JA-83M - Wireless Magnetic Door/Window Detector 

The JA-83M is designed to detect opening windows, 
doors etc. It can be installed onto most plastic or 

 

wooden frames.

The JA-83M detector is suitable for indoor installations only.

Installation should only be undertaken by technicians holding 
a certificate issued by an authorised distributor. The detector 
must not be exposed to bending or other deformation, as it 
may become damaged. 

Choose the suitable place for detector’s installation. The 
detector reacts to the removal of its magnet unit. The 
electronics should be installed onto the non-moving part 
of windows or doors, and the magnet onto the moving 
part. Avoid locating it directly on a metal frame as metal 
influences the functioning of the magnetic sensor and radio 
communication.

Installation - Overview

1. Open the detector cover by pressing the tab in (Fig. 1).

2. Screw the rear cover to the solid part of the door/window. 
The marks A and B show the right position of the magnet. 
(Fig. 3)

3. Attach the magnet to the moving part of the window. The 
standard magnet in a plastic housing opposite the A arrow 
and the small round magnet against the B arrow. Its distance 
from the detector should be as small as possible when the 
door/window is closed. In the picture Fig. A and Fig. 6 are 
shown the reaction areas for magnets in millimeters in three 
axes of movement and on the non-magnetic / magnetic 
surface. Note: Use the supplied plastic spacer to compensate 
for possible height difference for magnet A.

4. Pair the detector to an actuator/receiver. Check the 
actuator’s manual for more information. The RF wireless 
signal is only transmited when the battery is inserted. 
Note: To pair a detector after having already connected a 
battery,  first  disconnect  the  battery,  then  press  and  release 
the tamper sensor to discharge any remaining charge to get 
the device ready for pairing.

5. Mount the front cover onto the rear part.

6. Test the detector’s function.

7. The tab can be fixed using supplied screw (Fig. 2).

8. Programming of the detector to switching receiver see 
overleaf.
