Professional Smoke & CO Detector Installation
From single detector replacement to whole-home systems, AMY Electric installs smoke and CO detectors to current NFPA 72 and LA fire code requirements. We ensure proper placement, interconnectivity, battery backup, and testing.
Hardwired Smoke Detectors
120V interconnected smoke detectors with 9V battery backup. Required in bedrooms, hallways, and on every level of the home.
Carbon Monoxide Detectors
Hardwired CO detectors with battery backup. Required near sleeping areas and fuel-burning appliances (furnace, water heater, fireplace).
Combination Smoke/CO Detectors
Single unit detecting both smoke and carbon monoxide. Saves space while providing dual protection.
Battery Backup & Power Failure
All hardwired detectors include 9V battery backup to maintain protection during power outages.
Interconnected Systems
When one detector sounds, all detectors in the home sound. Critical for early warning throughout the house.
Proper Placement & Spacing
We follow NFPA 72 guidelines: detectors in every bedroom, outside sleeping areas, and on every level including basements.
Smoke & CO Detector Installation Process
We evaluate your current detector placement, wiring, and needs. We provide a firm quote for the recommended installation.
Most detector replacements don't require permits. New circuits or panel work do — we handle all permitting with LADBS.
We shut off the relevant circuit, verify it's dead, and work using insulated tools and PPE.
Old detectors removed, new ones installed with proper wiring to box, interconnect wiring, and battery backup connected.
We test each detector individually, test the interconnect system, and show you the hush button and test function before we leave.
