Description of functions - VdS shunt lock
In alarm-secured objects, a false alarm is triggered if the alarm system has already been activated externally and someone inadvertently enters the secured area. An external activation takes place, for example, through burglar alarm systems (EMA).
The VdS block lock function 3066 (VdS number G 101 160) blocks the locks during activation and thus prevents false alarms. No extensive work on the door or door frame is required.
The block lock function always consists of at least two components:
Activation units | Deactivation units |
|---|---|
Deactivation units are used to switch the alarm system. You require at least one activation unit for external activation and deactivation. If you want to activate or deactivate from several locations, you need one activation unit for each location. Transponders that are authorised on the activation unit in the locking plan can activation and deactivation. There are activation masters and activation slaves. The activation master can activate the alarm system with a potential-free contact. The activation slaves send a request for activation to the activation master, which then activates the alarm system. The activation slaves can activate the alarm system internally if they are connected separately to the internal activation connection of the burglar alarm panel. | Deactivation units prevent the doors from being opened accidentally. You need one deactivation unit for each door to the secured area. The deactivation units are installed next to the doors to the secured area. When the alarm system is activated, the doors cannot be opened inadvertently even with an authorised transponder. |
