What distinguishes a smoke detector from a smoke alarm?

The distinction between a smoke detector and a smoke alarm primarily revolves around their functionality and interconnectivity within a safety system. A smoke detector often refers to a device that detects smoke and is usually part of a larger, interconnected home safety system. When smoke is detected, it sends a signal to a central system, which can then alert occupants either audibly or visually as well as notify emergency services in some advanced systems.

On the other hand, a smoke alarm is typically a self-contained unit that triggers an alarm locally when it detects smoke. While it serves the same fundamental purpose of warning occupants about smoke, it does not have the capability to communicate with other devices or systems. This is important in terms of giving effective alerts throughout a larger building or home in case of a fire.

This understanding highlights how interconnected systems can provide enhanced safety and responsiveness compared to standalone units.
