The security secret word (also known as the central station passcode) is used in alarm situations when the central monitoring station calls the emergency contact(s) to verify an alarm. It validates that the person answering the telephone is authorized to take the call.
When an alarm is sent to a central monitoring station, they will attempt to contact you to verify that a true emergency is occurring. When you answer, the operator will ask for your secret word as an additional verification.
