Alarm Relay Operation

Both normally closed (NC) and normally open (NO) alarm contacts are provided. These refer to the alarm state.
Under normal conditions, the NC contact is closed and the NO contact is open. When an alarm condition is
present or the door contact is open, the NC contact will open and the NO contact will close. System power
failure will give an alarm condition.
