• A. Conventional system
• B. Addressable system
• C. Pre-signal system
• D. Local system

Answer: (C)

This item tests how alarm signaling can be staged so staff can verify a fire before everyone is alerted. A pre-signal system sends the initial alarm only to attended, central locations such as department offices, control rooms, or fire stations. This lets on-duty personnel hear and assess the situation before occupants are alerted. If the event is confirmed or the situation requires it, the system can then trigger the full alarm for the entire area. This approach helps reduce false alarms and unnecessary evacuations in large or complex buildings. A local system would only sound at the triggering device, and conventional or addressable terms describe device organization and identification, not the staged central signaling behavior.
