Why Detector Placement and Installation Matter

A smoke or carbon monoxide detector that isn’t placed correctly, isn’t properly powered, or hasn’t been tested in years provides a false sense of security. Illinois law requires smoke detectors on every level of the home, inside each sleeping room, and outside each sleeping area. Carbon monoxide detectors are required in any home with a fuel-burning appliance or attached garage. Battery-operated units meet the minimum requirement, but hardwired detectors with battery backup are more reliable, can’t be disabled by a dead battery, and in interconnected systems will trigger every alarm in the home simultaneously when one detects a problem. Five Star installs hardwired, interconnected detector systems that meet current Illinois code and provide the level of protection your household actually needs.

Carbon Monoxide: The Invisible Risk

Carbon monoxide is odorless and colorless, which means it cannot be detected by sight or smell. It is produced by any fuel-burning appliance in the home, including the furnace, water heater, gas dryer, stove, and attached garage. A malfunctioning furnace heat exchanger, a blocked flue, or a car left running briefly in an attached garage can elevate CO levels in the home to dangerous concentrations without any warning other than a functioning detector. This is not a theoretical risk, and a CO detector that is past its service life, typically five to seven years, may not respond reliably when it counts. Five Star replaces aging CO detectors and can assess whether your current placement provides adequate coverage for your home’s layout.

Combination Units and Smart Detectors

Modern combination smoke and CO detectors simplify installation and reduce the number of devices on the ceiling without compromising protection. Smart detectors add the ability to receive alerts on your phone when an alarm triggers, which is particularly valuable for vacation homes, rental properties, or any situation where the home may be unoccupied for periods of time. Five Star installs both standard and smart detector systems and will help you determine which type makes the most sense for your household.

When to Replace Your Detectors

Smoke detectors have a recommended replacement interval of ten years from the manufacture date, not the installation date. CO detectors typically need replacement every five to seven years. Many homes have detectors that have long exceeded these intervals without the homeowners realizing it. If you don’t know when your detectors were manufactured, checking the date stamped on the back of each unit is a quick way to find out. If they’re overdue, Five Star can replace the full set efficiently in a single visit.

Frequently Asked Questions
How many smoke and CO detectors does my home need?
Illinois requires a smoke detector on every level of the home, inside each sleeping room, and outside each sleeping area. Carbon monoxide detectors are required on every level of the home and outside each sleeping area in any home with a fuel-burning appliance or attached garage. If your home doesn’t currently meet these requirements, Five Star can assess your existing coverage and install what’s needed in a single visit.
Battery-operated detectors are standalone units that rely entirely on their batteries to function. Hardwired detectors are connected to the home’s electrical system with a battery backup, and when installed as an interconnected system, triggering one alarm activates all of them simultaneously. This is a significant safety advantage in larger homes where an alarm at one end of the house may not be audible in a bedroom at the other end. Hardwired interconnected systems are the standard Five Star recommends and installs.
Most CO detectors have a test button that confirms the alarm function is working, but this doesn’t verify that the sensor itself is still sensitive to carbon monoxide. CO detector sensors degrade over time regardless of whether the unit has ever alarmed. If your CO detector is more than five to seven years old, the sensor may no longer respond reliably even if the unit powers on and the test button works. Replacement on schedule is the only reliable way to ensure the sensor is functioning.
