WTHR-TV in Indianapolis conducted an aquarium test to show the dramatic difference between ionization and photoelectric smoke alarms. Inspired by a similar demonstration by the World Fire Safety Foundation, investigative reporter Bob Segall shows why smoke alarms with photoelectric technology are a much better option for detecting slow-burning smoky fires, which kill hundreds of people in homes and apartments each year. This news report first aired on WTHR-TV July 30, 2007.

@firealarmfreak5 CO alarms must measure the CO concetration over time. In the US must comply with the the UL 2034 standard. The standard requires the following:
At 70 parts per million: Unit must sound alarm within 60-240 minutes
At 150 parts per million: Unit must sound alarm within 10-50 minutes
At 400 parts per million: Unit must sound alarm within 4-15 minutes
So in the aquarium test, the alarm had to sense on of the levels for a given period before it alarmed. Hope that helps.

The issue with the slow response of ionization smoke alarms is a well documented issue. 95% of all US/Canadian homes have ionization alarms installed. The survival rate in a typical residential fire is only 40%. Photoelectric alarms have roughly a 96% survival rate. Around 20% of the time, an ionization alarm will never sound. Ionization alarms are also notorious for nuisance trips when cooking and are 8x's more likely to be intentionally discabled.

@PinkJazzX Maybe it is rigged how could you tell from this, anyone who says this is a fair test is a liar, why not put both detectors in at the same time? because that would be fair test?

It took over 8 minutes for the CO detector to go off?
