Non franchement.. autant aux USA qu'en Chine, ils sont tous d'accord avec cette définition :
NOTICE:Magnetic contact NC Normally Close definition:
Form A is Normally Open without the energizing force applied (the magnet in this case).
The closed sensors, loops or zones referred to on alarm systems are with the energizing force applied. Form A + magnet = closed sensor.
