Can a stand alone smoke detector be added to a building with a central alarm?
On One Hand: A Stand-Alone Smoke Detector Can Be AddedA stand-alone smoke detector can be added to a building with a central alarm. The smoke detector runs on batteries and functions separately from the central alarm. A stand-alone alarm may be needed in places such as closets or cupboards, where a central alarm may not detect smoke or fire.On the Other: Stand-Alone Detector Won’t Trigger Central AlarmThe stand-alone smoke detector will not trigger the central alarm if it goes off, because it is not part of the centralized system. Also, the stand-alone detector will only provide advanced notice of smoke or fire to a localized area. Persons in that vicinity would then need to trigger the central alarm to alert the rest of the building.Bottom LineA stand-alone smoke detector can enhance a central alarm system by providing faster alerts of smoke or fire in isolated places in the building.
