OAC (Optional Alarm Contact)
The OAC is an optional alarm which can be assigned with one of several types of alarms. When the assigned alarm is activated, the alarm will display on
the P_SE embedded display. The OAC also has a physical contact which closes with the activation of the OAC alarm. Refer to the
for
the list of available OAC alarm assignments.
The OAC is configurable by assigning it an alarm type (assignment), and the contact behaviour (reset mode), which can made using one or a combination of
the below methods:
-
TPED

The physical contact mode is defined as either Auto-reset mode, or latching mode:
Auto-reset mode:
Contact will remain CLOSED for up to 500ms after the alarm deactivates, at which point it will OPEN automatically.
Latching mode:
Contact will remain CLOSED after the alarm deactivates, until the alarm is cleared via the P_SE embedded display or the TPED
