submitted by Dorothy - 7 years ago
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.
