Locking element with counterpart and door contact

VdS C Door locking element with counterpart and opening detector

Well protected, inevitably false alarm-proof: The motorised locking element with opening detector prevents entry into an armed area and triggers the intruder alarm when the door is broken open.


Rule out alarms due to incorrect operation

No authorised user should unintentionally enter an area in the building that is monitored by an armed intruder alarm system. This is effectively prevented if all doors to the security area are equipped with the motorised locking element including its counterpart. This means that the door can only be opened after the system has been disarmed.

Inevitably user-friendly & secure
The motorised lock is activated and deactivated by the electronic control via the intruder alarm system. If the IAS or wired alarm system is armed, the door is locked. If the alarm system is disarmed, the door is unlocked. Thus, with the VdS C certified locking element, the intruder alarm system forces the user to take action before entering.

Fits in doors made of metal, plastic, wood and glass
The locking element is suitable for installation in plastic, wooden and metal door frames. With the surface-mounted housing available, the locking element can also be used with glass doors without any problems.

Reports forced entry
The locking element knows its status (open, closed) via lock monitoring and reports forced opening of the door to the alarm control panel.
