AJAX Fire Protect User Manual

The location of the detector depends on its remoteness from the hub, and
obstacles hindering the radio signal transmission: walls, floors, large
objects inside the room.
Check the Jeweller signal level at the installation location
If the signal level is low (one bar), we cannot guarantee the stable
operation of the detector. Take all possible measures to improve the quality
of the signal. At least, move the detector: even a 20 cm shift can
significantly improve the quality of signal reception.
If the detector has low or unstable signal strength even after moving, use
a ReX Radio signal range extender.
Install the detector at the ceiling in the highest point where hot air and
smoke are concentrated in case of fire.
If there are any beams at the ceiling, protruding by 30 or more centimetres
from the ceiling level, install the detector between every two beams.
Installation procedure
Before installing the detector, make sure that you have selected the optimal
location that follows the guidelines of this manual!
