Setting the jumpers at the slave - VdS shunt lock

Jumper B1

Jumper connects B1.b and B1.c: Activation slave beeps after activation release (acknowledgement of activation request by activation master)
Jumper connects B1.b and B1.a: Activation slave beeps when burglar alarm system pulls pin 29 on the activation master to ground (VdS-compliant: Acknowledgement of activation by burglar alarm system)

If jumper B2 is inserted, the range of the internal antenna is maximised. The range of the optional external antenna remains unchanged.

You limit the range of the external antenna with an aluminium sleeve (see Connection of the external antenna at the slave (optional)). In this case, set the jumper.

Using the external antenna without an aluminium sleeve is not VdS-compliant (see VdS requirements).

Do not plug in jumper B3.
