Activation units with button, without separate antenna - VdS shunt lock

The combination with a button allows operation without separate antenna, where activation is only possible from the outside. For each activation unit there is one opening button on the outside and connects pin 13 (activation master) or pin 12 (activation slaves) with ground potential, thus preventing activation.

Activation is only possible if the button on the outside is pressed and the user simultaneously activates his transponder. Since the button is located on the outside, it is ensured that the user is no longer in the secured area.

Activation master

With activation masters, the deactivation acknowledgement is suppressed as long as pin 13 is connected to ground (see also Global activation suppression (optional) and Connections of the activation master).

Use an opening button to connect pin 13 to ground potential. Also do not plug jumper B2 to maximise the range.

A Schottky diode decouples the deactivation line. It is only required if activation slaves are used.

Activation slaves

For activation slaves, connect pin 12 to ground to prevent activation on this activation master (see also Local activation suppression (optional) und Connections of the activation slave).

Use an opening button to connect pin 12 to ground potential. Also do not plug jumper B2 to maximise the range.
