Why do alarm monitors use authentication codes?

• A. They are used with trained/authorized alarm monitors to ensure alarm monitors are authorized and not under duress
• B. To encrypt data
• C. To identify the facility
• D. To track shift changes

Answer: (A)

Authentication codes verify that the person operating the alarm system is a trained, authorized monitor. When a code is entered, the system checks it against a secure list, grants access only to those approved, and logs who activated or changed settings. This ensures only legitimate operators can control the system and provides an audit trail for accountability. Some codes can also serve as a discreet distress signal, allowing the operator to indicate danger without tipping off a threat. This is why the main purpose is validating identity and authorization and, in some cases, enabling safe signaling under duress. Encryption, identifying the facility, or tracking shift changes aren’t the primary roles of these authentication codes, which is why they aren’t the best fit here.
