Circuit Behavior
This command determines whether the circuit stays open or closed when
no alarms are active. The opposite behavior occurs for an active alarm con-
dition. Default is normally open. Choose normally open if you want the
Alarm Output data logger to leave an electrical device OFF unless an
alarm condition occurs. Choose normally closed if you want the Alarm
Output data logger to leave an electrical device ON unless an alarm condi-
tion occurs. Normally open mode conserves console or Envoy battery
power.
Note: This command only affects the output tab that is currently selected.
Default
Press this button to restore the data entries to their default values. You must
still hit OK to save the settings in the data logger.
Output
Select the appropriate tab (Output 1 - 4) to configure the alarm settings for
each output.
For each output, select the first parameter you want to test. (If using the
“Minus” check type, you will need to select a second parameter after you
select the Minus check type.)
Then, select what type of test condition you want to check it against:
• A Greater Than or = (or high alarm) checks whether the current value
is greater than or equal to the value entered.
