Smoke and Carbon Monoxide Detector Installation in Seattle

Smoke and carbon monoxide detectors are essential for protecting your home and complying with local fire codes. Mirsky Electric provides professional installation, inspection, and maintenance to ensure your detectors are properly placed, fully functional, and code-compliant.

Our Smoke and Carbon Monoxide Detector Services

Whether you need a new installation, routine testing, or a system upgrade, Mirsky Electric’s team of licensed electricians ensure your smoke and carbon monoxide detectors provide reliable, code-compliant protection to keep your home safe.

New Installations

We install hardwired and battery-operated smoke or carbon monoxide detectors that comply with Seattle fire codes. Our team determines the best locations for new detectors to ensure complete coverage and seamless integration with your home’s electrical system.

Inspection & Testing

Detectors can fail due to dust buildup, dead batteries, or wiring issues. We conduct comprehensive testing and inspections to check battery life, sensor performance, and system wiring and confirm your alarms are operational. Our electricians will also ensure each detector is positioned for optimal functionality. 

Upgrades & Replacements

Smoke and carbon monoxide detectors have limited lifespans. If your system is outdated or malfunctioning, we’re here to provide expert recommendations and professionally install upgraded units.

Battery-Operated to Hardwired Detectors

Upgrading to hardwired detectors enhances safety by providing continuous power and ensuring alarms remain functional even if a battery fails. We specialize in converting battery-operated systems to hardwired ones, ensuring your home meets Seattle’s latest fire safety standards.

Smart Detector Integration

Smart smoke and carbon monoxide detectors provide real-time alerts and remote monitoring through your smart home system. These advanced systems integrate with your home automation system and notify you immediately—whether you’re home or away—ensuring you can act quickly in case of smoke or carbon monoxide detection.

Carbon Dioxide (CO₂) Detectors

For properties requiring indoor air quality monitoring, we install CO₂ detectors to track carbon dioxide levels in enclosed spaces. Unlike carbon monoxide detectors, CO₂ monitors do not detect toxic gas leaks but help maintain safe and breathable indoor environments.

Heat Detectors

We install heat detectors in areas where traditional smoke alarms may trigger false alarms due to cooking fumes, dust, or humidity. Unlike smoke detectors, heat detectors respond to rapid temperature increases, making them ideal for kitchens, garages, attics, and mechanical rooms.

Natural Gas Detectors

We provide natural gas detector installation to help protect homes from methane, propane, and other combustible gas leaks. These detectors offer early warnings of a potential gas buildup from appliances like stoves, furnaces, and water heaters, reducing the risk of fire hazards and carbon monoxide exposure. 

 

Seattle Smoke and Carbon Monoxide Alarm Requirements


Seattle follows Washington State building codes (WAC 51-51-0314 and WAC 51-51-0315) for smoke and carbon monoxide alarms in residential properties and applies when upgrading or replacing detectors in new construction, remodels, rental properties, and existing homes.

Smoke Alarm Requirements
 

Every residence must have smoke alarms installed:

    • Inside each sleeping room (bedroom).
    • Outside each sleeping area, in hallways leading to bedrooms.
    • On each level of the home, including basements.
    • Away from air vents, windows, or doors.

For new construction and significant remodels, smoke alarms must be:

    • Hardwired with a battery backup.
    • Interconnected, so if one alarm activates, all alarms sound.

Older homes undergoing updates that require a permit must bring smoke alarms up to current code requirements.

Carbon Monoxide (CO) Alarm Requirements

 

CO alarms are required in homes with:

    • Fuel-burning appliances (e.g., gas stoves, furnaces, fireplaces, water heaters).
    • Attached garages where exhaust fumes could enter living spaces.

CO alarms must be placed:

    • Outside each sleeping area, in hallways leading to bedrooms.
    • On every floor, including basements.
    • Inside bedrooms with fuel-burning appliances or direct access to an attached garage.

For new construction and remodels, CO alarms must be hardwired with battery backup and interconnected if multiple alarms are installed.

Rental Property Requirements
 

Landlords must install and maintain working smoke and CO alarms in rental properties. Tenants are responsible for replacing detachable batteries but cannot remove or disable alarms.

Why Professional Alarm Installation Is Essential

Installing smoke and carbon monoxide detectors may seem straightforward, but Seattle’s fire codes require hardwired alarms with battery backup in new construction and remodeled homes. A licensed electrician must install them to ensure they function correctly and comply with the code.

At Mirsky Electric, we take fire safety seriously, and thus we provide code-compliant installations to prevent penalties and failed inspections.

    • Correct detector placement for full home coverage and optimal protection.
    • Reliable wiring and battery backup to ensure alarms work even during power outages.

Our team ensures your smoke and carbon monoxide detectors meet all local fire safety regulations, giving you peace of mind that your home is safe, compliant, and fully protected.

FAQs – Smoke and Carbon Monoxide Detector Installation in Seattle

Do smoke and carbon monoxide detectors need to be professionally maintained?

While you should test alarms monthly and replace batteries as needed, professional inspections ensure proper wiring, placement, and functionality. A licensed electrician can also identify outdated or malfunctioning units that may not provide full protection.

Are combination smoke and carbon monoxide detectors a good option?

Yes, combination detectors provide fire and CO detection in a single device. However, placement is crucial, so be sure to have them installed according to manufacturer recommendations for proper function.

Do smart smoke and CO detectors work during power outages?

Yes, smart detectors with a battery backup will continue functioning even if the power goes out. These models can also send alerts to your phone or smart home system, ensuring you stay informed even if you’re away.

What should I do if my smoke or CO detector keeps chirping?

A chirping alarm typically signals a low battery, but it could also indicate a sensor nearing the end of its lifespan; dust or debris interfering with the unit; or a malfunction requiring replacement. If replacing the battery doesn’t resolve the issue, a professional inspection may be needed.

Can I install a smoke or CO detector near my kitchen?

Yes, but it should be installed at least 10 feet from stoves and ovens to prevent false alarms. Heat detectors can be used in kitchens instead of smoke alarms, as they detect rapid temperature increases rather than smoke.

What’s the best type of smoke detector for my home?

There are two main types of smoke detectors:

  • Ionization smoke alarms: Respond faster to fast-flaming fires (e.g., paper or grease fires).
  • Photoelectric smoke alarms: Better at detecting slow, smoldering fires (e.g., upholstery or electrical fires).

For best protection, experts recommend using both types or a dual-sensor alarm.
