EXAMPLE 1
Here the control unit is installed on the ground floor, in an off-centre positions, in a three floor building.
In this case the various architectonic infrastructures and the lack of "hostile" obstructions allow good transmission
signals from most of the sensors and the keyboard towards the control unit, good transmission levels from the
control unit towards the actuator but decrease both the self-powered siren command transmission signals and a
reception signal from one of the GW 20 477 movement sensors. GW 20 475 system status display module

SOLUTION 1
One option is to move the control unit to a central position on the first floor.
This solution maintains the previous quality of the signals from the sensors and the actuator, and now permits good
transmission levels from the control unit towards the self-powered siren and good reception from the GW 20 477
movement sensors, which were previously critical. To make things easier for the user, the position of the keyboard
on the ground floor is also moved without creating any signal problems.
