5.4. ALARM SETTINGS
The SiteWatch™ laser has four types of alarms, zone alarms, reference point alarms, time/heartbeat alarms and
weather alarms. All alarms are designed for network communication, but the built-in relay can also be used.
5.4.1. Zone alarms
Zone alarms are standard alarms for object detection. Up to 20 zones can be created and each zone can have
individual settings and alarm actions.
1. Open the Alarm settings tab.
2. Press ‘+ Add zone’ to create a new alarm zone. Input fields will appear on the right.
3. Enter a zone name.
4. Under ‘near distance’, enter the distance at which the zone should start.
5. Under ‘far distance’, enter the distance at which the zone should end.
6. Click ‘Add alarm’ to save the settings.
The laser sensor also oers advanced alarm settings. These settings can be used to adapt the zones for special pur-
poses. We recommend to thoroughly verify the function of the alarm zone if these settings are changed.
7. Press ‘Advanced settings’ to show the additional settings options.
8. Sensitivity: use the sensitivity bar to adjust the detection sensitivity. High sensitivity levels can be used for appli-
cations where highest detection is necessary. This may also increase the probability of false alarms. Low sensitivi-
ty can be used where the objects are big and slow (for example: detection of boats).
9. Delay: allow a zone alarm to react if an object has stopped in the zone. Enter the time for which an object must
stay in the zone before the alarm is activated. Default value is 0 seconds, maximum is 120 second (2 minutes).
10. Timeout: the time before a zone alarm resets once an object has been detected. This can be used to avoid extra
alarms from objects that may create multiple detections (for example: masts on a boat). Default value is 0 sec-
onds, maximum is 120 seconds (2 minutes).
11. Speed limit: enter a speed limit which an object must travel before the alarm is activated. Enter in meters per
second.
Repeat the steps above for each new zone.
To edit a zone, press the zone name.
To remove a zone, press ‘Remove’ next to the zone name. The zone and all actions for the zone will be removed.
