| Abstract | |||||||
|
This sensor is used to detect vibration, vandalism, destruction and theft. It measures acceleration along one axis. The sensor can be connected to a Sensor Input Component of an ELM system. Actions are defined by assigning relay components or alarms and setting proper thresholds. The power supply is done by the ELM system.
The sensor is contained within a case with two mounting holes.

| Set points |
Recommendations: Both set points should be set very close to the normal value given by the sensor. Usually an alarm line should be assigned to both set points. The latch mode should be used for the alarm. |
