Smoke detectors on power supply
- 5 smoke detectors
You connect a smoke detector that works on the power grid to an existing power source in your home or office. With a smoke detector connected to the power grid, you never have to deal with empty batteries. What you should pay attention to is whether the smoke detector has backup batteries. These ensure that the smoke detector still functions during a power outage.
