Frequently asked questions

Are hardwired smoke detectors better than battery-only? +

Yes. Hardwired detectors are interconnected—if one senses smoke, every alarm sounds. They also have battery backup for power outages. Georgia code requires at least one hardwired unit per level; we recommend combo smoke + CO for bedrooms and hallways.

How much does it cost to hardwire all my alarms? +

Installation runs $120–$250 per device (typically 4–6 units per home). We run new circuits, label them clearly, and test each alarm. Battery backup is included. Most homes invest $500–$1,500 for full coverage.

Do interconnected smoke alarms require a permit? +

No separate permit needed if you're adding to existing circuits. However, new 120V circuits for alarms must be pulled with your electrical permit if rough-in requires drywall patching. We handle the paperwork and inspection.
