Library Security Pedestal 2
22/62 Revision 4.2 July 2008
4.3.3 Installing the Pedestal
Once the L-SP2 will be powered, the photoelectric sensor will emit a red light beam. To
precisely align the sensor and the reflector, an orange LED is present on the back of the
photoelectric sensor. When the orange LED is continuously on, the sensor and the reflector are
perfectly aligned.
Figure 6: Photoelectric sensor
On the contrary the orange LED is blinking, and then you have to adjust the photoelectric sensor,
so that the red light beam is centered with the opposite reflector. This operation is achieved using a
white paper to clearly see where the red light beam is pointed at. When perfectly centered, the
orange LED will continuously be ON.
Special attention must be taken for the 2 pedestals positioning:
 They must be positioned face to face
 They must be parallel
 They must be aligned
 The orange LED must be continuously ON when powered
Then the 2 pedestals can be secured to the ground.
A good positioning will ensure the red LED beam to be reflected by the reflector as shown below.
