Car Park 3 – General installation

2 Install the bases
Before installing the SBPSUSLxx sensors, you must install the base holders. The bases must be
fixed in a hard and straight surface.
Notice: rubble, sand and grass cannot be used as surface.
The bases must always be installed on the ceiling.
If water and snow are covering the surface, the sensor cannot detect the car. If a car is covered with
snow, the sensor cannot detect the car.
Be sure to mount the base correctly so that the sensor points towards the car park bays.
When the base holder is used with the SBPSUSL45 lane sensor, it must be mounted on the ceiling
or in a rail with an angle of maximum ± 5° degrees vertical deviation and ± 2° degrees horizontal
deviation from the ceiling surface. See the picture below:
When the base holder is used with the SBPSUSL vertical sensor, it must be mounted on the ceiling
or in a rail with an angle of maximum ± 5° degrees vertical deviation from the ceiling surface. See
the picture below:
Both type of sensors sends out a 40 kHz ultrasonic signal, and that the receiver inside the sensor
must to be able to detect the returning signal without problems. If the angle exceeds the maximum
deviation value or the surface is of poor quality, the signal can be interrupted and the sensor red
LEDs start flashing.
