Which description best matches a local alarm that sounds only within the premises?

• A. Zone Noncoded
• B. Central Station
• C. Auxiliary
• D. Protected Premise Local Alarm

Answer: (D)

The key idea is where the alarm signal is heard and who is alerted. When an alarm sounds only on the premises, it means there’s no transmission to an off-site monitoring service or central station. That’s exactly what a Protected Premise Local Alarm describes: an alarm system that produces audible (and sometimes visual) notification inside the building for occupants without sending a signal to a monitoring organization. It’s purely local protection. The other terms describe different signaling arrangements. Central Station means the alarm signal goes to a monitoring center, not just to people on-site. Auxiliary refers to a signaling setup that involves an additional monitoring or supervisory path, not limited to on-site notification. Zone Noncoded describes how a specific area or zone is coded within the system, not where the alarm is audible.
