CURTAIN DIMENSIONS
3.2.2.1 GS-120 Basic System
The curtain dimensions are defined by the protected
height and the range (i.e. the distance between the
emitter and receiver units). The protected height must
be selected to suit the application. The minimum range
for all systems is 500 millimeters. The maximum range
for systems with 30mm or 70mm detection capability is
15 meters (50 feet).
All the dimensions relating to the curtain, for each of the
GS-120 systems are shown in
Figure 12
. The upper
and lower boundaries of the curtain are indicated by
arrows on the front window labels of each unit.
