
Enabled - Indicates whether magnetometer is enabled for use. Enabling magnetometer
performs a calibration to zero the current coordinate values.

Trigger Thresholds - used to configure the device’s sensitivity. Merely rotating the unit or
moving it along any axis (for example, 6 to 12 inches) may be enough to trigger an alarm with
thresholds at the minimum values. Setting the thresholds at the maximum values will prevent
alarms from occurring under normal circumstances. However, unusual circumstances, such as
setting a strong magnet on the unit, may still trigger an alarm
- x-axis - alarm trigger threshold for x-axis. Default = 50 range : 25 - 2000
- y-axis - alarm trigger threshold for y-axis. Default = 50 range : 25 - 2000
- z-axis - alarm trigger threshold for z-axis. Default = 50 range : 25 - 2000
NOTE
None of these numbers for coordinates or thresholds has meaningful units. They are just values
that are all relative to each other. A value of 50 cannot be equated to a specific number such as
6 inches.
In the CLI to view this, enter configuration mode and execute the following command:
% show system tamper-detection magnetometer | details
enabled false;
trigger-thresholds {
x-axis 50;
y-axis 50;
z-axis 50;
}
Configuring
Set trigger thresholds and enable the device. This will start the calibration process. Use the Web UI as
show above, change the values, enable the device and press
Save .
On the CLI issue the following;
% set system tamper-detection magnetometer trigger-thresholds x-axis 25
% set system tamper-detection magnetometer trigger-thresholds y-axis 25
% set system tamper-detection magnetometer trigger-thresholds z-axis 100
% set system tamper-detection magnetometer enabled true
