At what ppm does this alert at? I heard the reason you need a different one for camping is lower ppm. Thanks.


Thank you for your question, Ruby. If the alarm is exposed to 400 ppm of CO, It must alarm between 4 and 15 minutes. If you have additional questions please don’t hesitate to reach out to us at First Alert at 1 (800)-323-9005.
