D21 Intrusion Detection Sensor
D21 disturbance sensors measure movement or the kinetic energy released within a structure when it is disturbed. They then signal an alarm event when certain pre-set parameters are exceeded.
In addition to Gallagher D21’s disturbance-measuring properties, this cost-effective sensor has a built-in tilt-measuring capability that monitors any angular change in the position of the sensor body.
The disturbance sensor guards against physical intrusion attempts or the moving of valuable assets. It can be applied both indoors and outdoors on fences, building cladding and roofs.
