Open/Close Contacts
The defaults that can be set for Open/Close contacts differ from the Temperature and
Humidity settings.
Normal State
Normal state specifies the condition in which a contact is considered to be in a Normal,
Non-alarmed state.
Devices such as smoke alarms and air conditioning units often have normally open con-
tacts. To receive alarm indications from these types of units would cause alarms to be
issued when a monitored contact closes.
Setting normally closed in the case of a rack or cabinet door would cause an alarm con-
dition when the door was opened.
Trigger Type
The trigger type defaults for Open/Close sensors are specified here.
The three available options for trigger types are:
Level
Level triggering is the default mode. When an input physically transitions from a Normal
to Non-Normal state, an alarm is triggered. However, the alarm persists only while the
input remains in a Non-Normal state. When the input returns to a normal state, the alarm
is cleared.
