- 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. » Watch more WTHR 13News:Watch Live and On-Demand Videos on WTHR | Indianapolis, Indiana | wthr.com

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.
@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.

Find out more at: www.SmokeAlarmWarning.org Australian legislation (Queensland and the Northern Territory) and legislation in Zealand and some U.S. States mandates the use of photoelectric smoke alarms. Many authorities advise photoelectric alarms as being "better" but for legal and political reasons are not allowed to warn that there is anything wrong with ionization alarms. However, in 2016 Commissioner Greg Mullins, the most senior fire official representing all fire brigades across Australia and New Zealand went public stating that "ionization smoke alarms should be banned". See him warning on Australian TV and discover why ionization smoke alarms should be banned: www.SmokeAlarmWarning.org

So people should buy photoelectric smoke detectors AND carbon monoxide detectors.
Yes, but you can get one device that does both. You don't need two separate devices. The ones that I have in my house also interconnect so that I can hear an alarm in my bedroom on the 2nd floor when there is CO or smoke in the basement 2 floors below me.
