Local activation suppression (optional) - VdS shunt lock

You can prevent activation of an activation slave by switching a potential-free contact between pin 12 and pin15. If the contact is closed, activation cannot be performed locally (from this activation slave). The activation behaviour of other activation units remains unchanged.

You can use this behaviour to ensure that a activation of the alarm system is only possible from the outside even without separate antenna (see Activation units with button, without separate antenna).
