What is the difference between a smoke alarm and a smoke detector?
According to the National Fire Protection Association (NFPA) a smoke alarm is “a single or multiple station alarm responsive to smoke.” In simple terms, residential smoke alarms contain a sensor and alarm in each individual unit. They define a smoke detector as “a device suitable for connection to a circuit that has a sensor that responds to a physical stimulus such as heat or smoke.” Commercial smoke detectors are the sensors that detect the presence of smoke or heat and initiate an alert from a separate alarm device.
