Should a CO detector be UL certified?

24 November 2018

Yes. A UL certified CO detector will meet established criteria for high quality alarms. A UL certified device will only alert after levels have increased to over 30 ppm and will alert more frequently as higher thresholds are reached. Also, a UL certified device’s alarm will be at least 85 decibels to ensure the alarm can be heard from at least 10’ away.
