                    Control lighting in classrooms

                     

                     

                     

                    Value proposition

                    Main drivers

                    • The training room fluorescent lights must come on when the presence of students in the room is detected, but only when the natural lighting is insufficient.
                    • They must go off when the natural lighting is sufficient or as soon as the room is empty, leading to energy saving.

                     

                    Value proposition

                    • Automation ensures up to 20% energy savings.
                    • Additional energy saving potential can be gained by including the heating or air conditioning in the system: example by using night economy when no movement is detected.

                     

                    Differentiation factors

                    Thanks to the CDP ARGUS presence detector's lighting control, which is dependent on movement and brightness, only classrooms which are actually in use will be lit.

                    • The maximum switching current per relay:

                       10 A, AC 230 V, cos phi 0.6

                       Incandescent lamp max. 2300 W

                       Halogen lamp max. 2000 W.

                    • The diagram shows the TT earthing system used in France:

                       The earthing system must be appropriate with the regulations in force in the country where the lighting is in use.

                     

                    Main Energy Efficiency characteristics

                    • The CDP ARGUS allows the lighting to be set from 10 to 1000 lux
                    • It detects the slightest motions within a radius of 14 metres at a mounting height of 2.5 metres
                    • Thanks to the 2 relay outlets not only the lighting but also the HVAC can be controlled with just one device
                    • You can also manually switch the lighting ON and OFF at any time using a pushbutton.
