Residential fire alarm systems are typically stand-alone smoke alarms. They detect smoke and sound locally in each unit, which makes them simple to install and cost-effective for homes. In many newer houses, several standalone units are interconnected so that if one alarm detects smoke, all sound, providing broad notice throughout the home, but the system is still composed of individual alarms rather than a centralized monitoring network. Central monitored systems, where signals go to a monitoring service, are more common in commercial buildings or large multi-unit dwellings and are not the standard for single-family residences. Heat detectors are used in places where smoke alarms might cause nuisance alarms, such as kitchens or garages, and are not the typical primary residential system. Photoelectric only refers to detector technology rather than the overall system type, and while photoelectric detectors are common, the everyday residential setup most often comprises stand-alone smoke alarms.
