Sentinel Pro Installation and Setup Guide
Table High
: The Table High value is used to define the upper range (20mA) of your 4-20mA sensor.
Alarm Delivery Enable/Disable
: When Enabled, alarm messages will be delivered, if set to Disabled
alarm messages will not be delivered.
Recognition Time
: This is the length of time that an alarm condition must be present before a valid
alarm exists and message delivery is started.
Alarm Hold Time
: When an alarm occurs, the
Alarm Hold Time
will latch the alarm condition for the
programmed time period, thus preventing redundant alarms from sending additional notification mes-
sages. This is useful for alarms that are likely to trip several times within a short time period, such as
motion detectors.
Return to Normal Enable/Disable
: This feature instructs the Sentinel Pro to send a message when a
zone input has changed from an alarm condition back to a normal condition. Anyone who received the
original alarm message will also be sent the Return-to-Normal message.
Alarm Reset Enable/Disable
: This setting enables or disables the Alarm Reset Feature. The Alarm Reset
feature is used to re-send alarm messages in the event that a fault condition is not corrected in a timely
fashion. If an alarm continues to exist for the duration of the programmed Reset Time (see below) the
alarm will reset (reactivate) and the alarm message delivery process will begin all over again. This is an
optional feature.
Alarm Reset Time
: This is the time allowed for an alarm’s fault condition to be corrected before the
Sentinel Pro resets (reactivates) the alarm and begins the message delivery process all over again. It is
recommended that this be set to no lower than 30 minutes to prevent numerous messages from being
sent.
Datalogging Mode
: The Sentinel Pro has two modes of data logging for each zone: Continuous or
While In Alarm. In Continuous mode the unit will log the value of the input on a fixed time interval
all the time. The Normal Interval sets the logging rate while the value is within the normal range. The
Alarm Interval sets the logging rate while the value is an alarm condition. By choosing the While In
Alarm mode you can choose to have the unit only log values when it exceeds the alarm limits.
Alarm Datalog Interval:
This is the interval that data will be logged while the input is beyond the pro-
grammed alarm limits. (Note: this is regardless of the programmed Alarm Recognition Time).
Normal Datalog Interval
: This is the interval that data will be logged while the input is within the pro-
grammed alarm limits. To maximize the available memory for datalogging, set the Datalog Interval for
each zone to multiples of each other. For example, Zone 1 can be set to 10 minutes, Zone 2 to 30 min-
utes, Zone 3 to 60 minutes, etc…
