CONTROL PANEL LOCATION
The control panel should be located in the control panel part of the object. The central
location of the control panel usually provides good communication with all wireless
detectors. See drawings 9 and 10.

The radio waves are attenuated by walls and other obstacles. Lowest attenuation have
wallboards and wooden frame. Medium attenuation have light concrete and brick walls.
Reinforced concrete and metal latticed plaster have the greatest attenuation. The drawing
11 shows the signal loss through various different types of materials. (
NOTE:
the figure is
simplified, only for illustration – remember that radio waves propagate multidirectionally).
