First Alert BRK Hardwired (with Battery Back-Up) Ionization Interconnected Smoke detector 6 -Pack
I have installed these in several new houses. When a vacuum or other high amperage device is plugged in and turned on some of the detectors will go off. This is happening in multiple houses, how do we prevent this?
