One Smoke Detector in the Wrong Location Won't Save You
Most people think smoke detector installation means buying a unit at a hardware store and screwing it into the ceiling. In Signal Hill, code-compliant smoke detection systems are more than that — they're interconnected, location-specific, and tied to hardwired power with battery backup.
When one alarm triggers, every alarm in the building should trigger. That's the interconnection standard that actually saves lives. And it requires an electrician, not a stepladder.
