Work to be done before installationGC 304 R
3.2 Positioning the sensor
The GC 304 is used as an activation sensor for automatic doors.
à The sensor must be mounted above the door in the case of sliding,
curved sliding, folding and revolving doors. Ideally, the ow of people
will walk directly towards the sensor. If the scanning area does not cover
the entire opening width or if the ow of people from dierent direc-
tions is to be expected, several GC 304 R sensors can be used.
à In the case of swing doors the sensor must be mounted on the hinge
side above the swivelling axis.
