Battery-powered Smoke and CO detectors can be placed anywhere and run on replaceable batteries (usually 9-volt or AA) or sealed lithium batteries. Hardwired detectors need appropriate wiring for power that’s typically observed only in newer or refurbished homes. Plug-in detectors get a continuous flow of power from a terminal.

Most smoke and carbon monoxide detectors resemble each other, so you might think they are the same. Not exactly. To ascertain the model you need, discard the sensors in your home from their mounts. If wires are attached to them that run into the wall or ceiling, you require hardwired detectors. If there are no cables, then you need battery-powered detectors.
