Deactivation unit without activation unit - VdS shunt lock

If the alarm system continues to be operated using a conventional key, no activation units are required. A relay contact is required on the burglar alarm system, which is closed when the alarm system is activated.

  1. Connect the power supply to the deactivation unit.
  2. Connect pins 13 and a ground connection (e.g. pin 15) to the relay contact of the alarm system (potential-free closing contact).
  3. Connect any existing bolt switch contact to pins 12 and 15 (see also Optional bolt contact evaluation (global activation suppression)).
  1. If the alarm system is activated, pin 13 is pulled to ground. The reaction is the same as a deactivation request from an activation unit: The deactivation unit deactivates its locking device.
  2. It is no longer possible to operate the locking device when the alarm is activated.
