Which alarm system is a local alarm that detects a fire and transmits an alarm on the immediate premises?

• A. Local
• B. Central
• C. Remote
• D. Audible only

Answer: (A)

Local alarms are designed to alert occupants on the premises without sending signals off-site. When detectors in a local system sense smoke or fire, the system triggers audible and/or visual alarms that are heard or seen within the building itself, providing immediate notice to people inside. It does not communicate with a monitoring company or a remote location. That on-site signaling is what defines a local alarm. In contrast, central systems send signals to a central monitoring station, and remote systems transmit to a location away from the premises. Audible-only describes the type of alert, not where the signal is transmitted.
