Can a combination smoke and carbon monoxide alarm replace two separate alarms?

Yes. A combination smoke and carbon monoxide alarm provides protection from both smoke and carbon monoxide in a single device. When installed in the proper locations, they can simplify maintenance while reducing the number of alarms needed throughout your home.

Are combination smoke and carbon monoxide alarms required in Missouri?

Many Missouri homes are required to have smoke alarms, and carbon monoxide alarms are recommended or required in homes with fuel-burning appliances, fireplaces, or attached garages depending on local building codes and the age of the home. We can evaluate your home and recommend the appropriate alarm locations for your situation.

How long do combination smoke and carbon monoxide alarms last?

Most combination smoke and carbon monoxide alarms should be replaced every 10 years, although some models have different replacement intervals. We always recommend checking the manufacturer's replacement date and replacing alarms before the sensors expire.

Do combination smoke and carbon monoxide alarms have backup batteries?

Yes. Most hardwired combination alarms include a backup battery that keeps the alarm operating during a power outage. Battery-operated models rely entirely on their internal batteries, while many newer models feature sealed 10-year lithium batteries that do not require annual battery replacement.

Can I upgrade my existing smoke alarms to combination smoke and carbon monoxide alarms?

Absolutely. Many homeowners choose to replace older smoke alarms with combination units to improve protection and reduce the number of devices installed throughout the home. Our technicians can determine which locations are best suited for combination alarms.

Will all of my combination alarms sound if one detects smoke or carbon monoxide?

If your alarms are properly interconnected—either hardwired or wirelessly—yes. When one compatible combination alarm detects smoke or carbon monoxide, every interconnected alarm throughout the home will sound, providing earlier warning no matter where the emergency begins.

What's the difference between a smoke alarm and a combination smoke and carbon monoxide alarm?

A smoke alarm detects smoke from a fire, while a combination alarm detects both smoke and carbon monoxide. Combination alarms provide two important life safety functions in one device, making them a popular choice for modern homes.

Where should combination smoke and carbon monoxide alarms be installed?

Combination alarms should be installed according to the manufacturer's instructions and current safety recommendations. Common locations include outside sleeping areas, on every level of the home, and in or near bedrooms where appropriate. Our technicians evaluate your home's layout to ensure proper placement for the best possible protection.

Do combination smoke and carbon monoxide alarms require maintenance?

Yes. Combination alarms should be tested monthly, kept free of dust and debris, and replaced when they reach the manufacturer's end-of-life date. During our annual inspections, we test each alarm, verify proper operation, inspect backup batteries, and confirm the entire system is functioning correctly.

Yes. We install combination smoke and carbon monoxide alarms that provide two forms of life safety protection in one professionally installed device.

Do hardwired carbon monoxide detectors have batteries?

Yes. Most hardwired carbon monoxide detectors include backup batteries that continue protecting your home during power outages.

Why is my carbon monoxide detector chirping?

A chirping carbon monoxide detector may indicate a low battery, an expired sensor, maintenance is required, or the alarm has reached the end of its service life.

Are wireless carbon monoxide detectors reliable?

Yes. Modern wireless interconnected carbon monoxide detectors are designed to provide dependable communication and whole-home notification without requiring new electrical wiring.

Can carbon monoxide detectors detect natural gas leaks?

No. Carbon monoxide detectors only detect carbon monoxide. They do not detect natural gas, propane, or other combustible gas leaks. Separate gas leak detectors are required for those hazards.

Do you inspect carbon monoxide detectors?

Absolutely. We inspect, test, clean, verify expiration dates, and evaluate placement to ensure your carbon monoxide protection is working properly.
