3.12.1 ALARM
Stations are able to notify alarm condition by sending SMS and/or starting a
CSD call to the controller PC.
Measurement results downloaded from any station include therefore
information of any alarm occurred during the monitoring activity.
Depending on the local laws, the place of installation, the climatic conditions,
the availability of sunlight and the duration of measurement, certain alarms
should be enabled for the control and proper operation of the field monitor.
In addition, if the station is installed in what is defined as a "sensitive"
locations as regards electromagnetic fields, the alarm for exceeding the
threshold defined by law should be enabled to ensure control almost in real
time.
Any alarm notification can be set on a dual threshold, with reference to the
occurrence of an event (OUT): i.e. exceeding a threshold; and upon
regaining normal conditions (IN).
OUT: enabled (ON pressed) or disabled (OFF pressed) notifies you of an
alarm in the following cases:
1.
On exceeding a threshold setting for attention (Warning)
2.
On exceeding an alarm threshold (Alarm);
3.
When battery voltage is too low (threshold is factory preset) or too high
4.
When one or more field probe parameters is faulty;
5.
On exceeding the temperature limit inside the field monitor;
6.
When the data memory is almost full
7.
When the external container is opened.
Whenever an alarm occurs, the GSM modem will remain on for 30
minutes to enable the operator to send an SMS message and query the
station and download the data.
IN: enabled (ON pressed) or disabled (OFF pressed) notifies you that
normal conditions have been restored.
When the monitoring station is off, the alarms are shown as off when
the station is switched on again.
