Figure 55 - Selecting the alarm severity
9.4.1.5
Comparison operator and value
The Comparison field is used to select the operator for creating the alarm strategy. The alarms are
looking for “
t
rue” statements and will alarm when the condition described is in the true state. The value
field is used with the operator to determine if the point being monitored is in the alarm condition.
Digital inputs are compared to 0 for OFF and 1 for ON. Thus, to create an alarm when the digital input
has an ON status, you would compare the input > (greater than) 0 or you could compare the input =
(equal to) 1, or input
≠
(not equal to) 0. Analog sensors such as temperature and humidity, use the
greater than (>) value or the less than (<) value for alarm condition determination. An example would
be if the zone temperature sensor is greater than 80 degrees. Alarm values are entered as integer
numbers.
