A central station operator places one or more phone calls in an attempt to verify that a real alarm has occurred and not a false alarm. Typically the first call placed is to the alarm location and the operator asks for a Code Word if there is an answer. If there is no answer, depending on your dispatch procedures, the operator may try one or more additional phone numbers in an attempt to reach someone. If no contact is made, or you do not give the Code Word, the operator will dispatch the authorities. Local jurisdictions that utilize enhanced call verification (operator must place 2 phone calls before dispatching an alarm event) have found that it greatly reduces the number of false alarms.
