- All First Alert CO alarms are rigorously tested to meet UL standards
The advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes.
Because CO evenly distributes itself, it's important to have a CO detector on every level and in every bedroom of your home. This easy-to-use alarm features a digital display that shows ambient temperature as well as peak CO levels. The detector's stylish design looks great on top of a dresser or table.
Q: Does this work the same if plugged into a surge protector?
A: Thank you for your question. This unit is not a plug in alarm and runs off of a 10-yr sealed battery.submitted byFirstAlertProductExpert - 3 years agoBrand expert
Q: How many PPM before this detects CM?
A: Thank you for reaching out. First Alert’s carbon monoxide alarms are designed to alarm before there is an immediate life threat. Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and exposure times as described below. They are measured in parts per million (PPM) of CO over time (in minutes). CO Level: 70 PPM, Alarm Response Time: 1 to 4 hours. CO Level 150 PPM: Alarm Response Time: 10 to 50 minutes. CO Level: 400 PPM, Alarm Response Time: 4 to 15 minutes.submitted byFirstAlertProductExpert - 3 years agoBrand expert
