The receiver sensitivity adjustment starts by going up to 100%, and then the
output power is increased to 100%. Additional output power is provided if
necessary to cover the distance, and the said levels are reduced when an
automatic alignment process takes place. The air quality at this point has to
remain at 0%.
8. Press Enter to confirm the beam pre-alignment and settings, press the right
button and enter a manual alignment mode.
The Firebeam detector searches for the far wall of the building. In case of
installations with short distances, FireBeam will stop raising the infrared beam
intensity. In such cases, you can press Enter to confirm the alignment, and then
press the right button and Enter to enter a manual adjustment mode.
Caution: If a free radius of 50-cm is impossible, and the detector beam is
obstructed by objects, the IR intensity will stop increasing and the beam
alignment will be stopped when the beam conducts a wrong calculation, as in the
case of striking the far wall. In this case, the obstacle has to be removed or the
detector location/alignment have to be adjusted. The following figure presents an
example for an obstacle in the beam path.
Obstacles next to the upper part of the beam will interfere with the alignment
process, therefore you must make sure there is no solid object close to the beam
path.
Ensure a free range along the beam of 1.50-m from the reflector ends.
If the wall on which the reflector is placed is shiny or made of glass, a surface in
the size of 1-m. made of a non-reflecting material like MDF, has to be installed on
it to allow correct operation.
Manual alignment
At the completion of pre-alignment of the beam, enter a manual alignment mode.
