Smoke & Carbon Monoxide Detector
Installation in Sonoma County

Smoke & CO Detection That Meets California Code

Working smoke and carbon monoxide detectors are the cheapest life-safety insurance in your home — and the most commonly neglected. Battery-only units get disabled when they chirp, older detectors quietly age past their rated life, and many Sonoma County homes were built before interconnected hardwired detection was required. When one alarm can't trigger the others, you lose the early warning that matters most at night.

Eleos Electric installs and replaces hardwired, interconnected smoke and carbon monoxide detectors throughout Windsor, Santa Rosa, Healdsburg, Rohnert Park, Petaluma, Sonoma, and Sebastopol. We place every unit to current California code, wire them so they all sound together, and add sealed battery backup — so your home is protected and ready for sale or transfer.

Detector Services We Provide

Hardwired Interconnected Detectors

We wire detectors together so that when one senses smoke, every alarm in the home sounds. This interconnection is required in new construction and major remodels, and it's the single biggest upgrade to your family's overnight warning time.

Combination Smoke/CO Detectors

Combination units protect against both smoke and carbon monoxide — the colorless, odorless gas produced by furnaces, water heaters, and attached garages. We install combo detectors where code and good practice call for them.

Detector Replacement & Upgrades

Smoke detectors have a service life of about ten years from their manufacture date, and CO detectors even less. We replace aged and chirping units with modern sealed 10-year detectors so you're not climbing ladders to change batteries.

Whole-Home Detector Wiring

For new construction, additions, and rewires, we design and install a complete interconnected detection system positioned to code on every level and in every required location.

Rental & Commercial Compliance

We bring rentals, ADUs, and commercial spaces into compliance with detector requirements so landlords and owners meet their obligations and pass inspection.

California Smoke & CO Requirements

California requires smoke alarms inside every bedroom, outside each sleeping area, and on every level of the home, including basements. Carbon monoxide alarms are required outside each sleeping area and on every level of any home with a fuel-burning appliance, fireplace, or attached garage. Detectors are also required to be present and working at the point of sale or transfer of a property.

Beyond placement, age matters: most smoke detectors are only rated for about ten years, after which their sensors degrade. If you can't remember when yours were installed, they're likely overdue. We check the date on every existing unit and tell you honestly what needs to be replaced — no upsell on detectors that still have life left.
