7 Design notes for induction loops
For assembly and inspection, see page 61, chapter 8.4.
Please observe following points when dimensioning the induction
loops:
Induction loops respond only to metal. The mass is thereby not
important, but the size of the loop's surface, which will be
covered by the metal part is.
The induction loops must not respond to persons or objects with
a small metal portion like a bicycle for instance.
Safety loops must secure the danger area underneath the
barrier arm throughout the entire length.
Opening loops must be installed right in front of the safety loop.
The maximum distance between safety loop and opening loop
must be not greater than max. 3.28 ft (1.0 m).
