Alarm Computation Details

This section contains details on how the system decides whether to go into alarms. The section is broken
down by the user chosen

Alarm Type

setting:

10.6.1

Hi Alarm

When the Alarm Type is set to Hi, if the sensor reading is greater than or equal to Alarm Threshold, the
station goes into alarm.

That station will go out of alarm when the sensor reading goes below Alarm Threshold minus Alarm
Deadband.

Hi alarm scenario:



System measures stage every 15 min



Hi Alarm threshold is at 2ft



Tx Alarm Interval is 5min



Once stage exceeds 2ft, the system sends out an alarm transmission



As long as stage is above 2ft, the system will send out alarm transmissions every 5min



Note how even though the measurement interval is 15min, the transmissions are fired off every
5min

10.6.2

Low Alarm

When the Alarm Type is set to Low, if the sensor reading is less than or equal to Alarm Threshold, the
station goes into alarm.

That station will go out of alarm when the sensor reading goes above Alarm Threshold plus Alarm
Deadband.

10.6.3

ROC Alarm

ROC stands for Rate Of Change. ROC alarms compare the current measurement reading with a past
reading. If

Alarm ROC Interval

Since Last Meas

, the past reading is the last scheduled reading made

according to

Measurement Time

and

Measurement Interval.

Alarm ROC Interval

Since Last Tx

, the past reading is the one that was included in the last alarm

transmission. If there is no past transmission, the first reading made after boot up is used.

If the absolute difference between the two readings (absolute of current reading minus past reading) is
greater or equal to the

Alarm Threshold

, the station goes into alarm.

The same station goes out of alarm if the absolute difference between the two readings (absolute of
current reading minus past reading) is less than the

Alarm Threshold

minus

Alarm Deadband.

Exception:

ROC alarms setup for

Since Last Tx

do not generate out of alarm events or transmissions.
