C. DETERMINATION OF THE NUMBER OF LOOP TURNS
WARNING :
For conformity reasons, in any situation, the antenna factor defined as the loop surface multiplied by the number of turns
should not exceed NA = 20
For example, if L=2m, Ea=1m and the number of turns=4, then the NA = 2x1x4 = 8 < 20.
Find hereafter the recommended values for the turns :
Area
< 3 m
3 - 5 m
6 - 10 m

C. RELAY CONFIGURATIONS (Dip Switch #3)
The loop A activates the relay A and the loop B activates the relay B. With the dual loops in combined mode the relay A
provides the presence detection and the relay B provides the movement direction
