Commercial security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while household smoke detectors, also known as smoke alarms, generally issue a local audible or visual alarm from the detector itself.

How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor.
