Which statement about a local alarm system is true?

• A. It notifies authorities immediately
• B. It requires central monitoring
• C. It sounds locally and does not automatically notify authorities
• D. It relies on internet alerts

Answer: (C)

Local alarm systems are designed to on-site alert people and deter intrusion without automatically calling for help. Their main function is to trigger the siren and any on-site indicators when a sensor is activated. They don’t have a built-in mechanism to notify police or fire departments unless they’re connected to a central monitoring service, which would move them beyond “local only.” So the statement that it sounds locally and does not automatically notify authorities captures this behavior. If you need authorities alerted automatically, you’d use a monitored system or add a monitoring service, which is a different setup from a pure local alarm.
