How to test DS-100 before use?
1.Lighted cigarette: Place the detector near cigarette smoke.
2.Smoldering paper: Light a piece of paper, extinguish the flame, and let it smolder. Place the detector and smoldering paper in a sealed, non-flammable container (such as a glass jar).
Why does the screen dim? Is my device still working?
To save power, DS-100 dims the screen after 5 minutes of inactivity, but the device does NOT SHUT DOWN and CONTINUES to detector CO levels in real time. Press function button to wake up the screen.
Why does the device sometimes fail to detect CO?
Not all combustion generates enough carbon monoxide to trigger detection. In well-ventilated areas or during complete combustion (e.g., a gas stove’s blue flame or a car engine running smoothly), CO levels may be too low for the detector to activate.
Why can’t DS-100 detect carbon dioxide (CO2)?
DS-100 detects carbon monoxide (CO), not carbon dioxide (CO2). CO is a colorless, odorless, toxic gas produced by incomplete combustion. CO2 produced during complete combustion is generally harmless unless it is present in very high concentrations.
Can DS-100 replace a fixed household CO alarm?
DS-100 is a portable detector that is ideal for travel, camping, or cars. It provides supplemental protection for the home, but it cannot completely replace a fixed carbon monoxide alarm that meets residential safety standards.
