And here's the take-away information...
"The International Association of Fire Fighters (IAFF) – the largest firefighters union in the U.S. and Canada – recommends photoelectric smoke detectors. During their 2008 conference, the IAFF adopted an official position recommending only photoelectric smoke alarms and stated that dual sensor alarms are no longer acceptable.
The technology used in ionization smoke detectors leads to a delayed warning in smoldering fires, which can lead to greater loss of life. Ionization detectors are also weaker in high airflow environments, so the delay may be even longer. Photoelectric smoke alarms are more effective at warning of smoke from smoldering fires and are less susceptible to nuisance alarms.
To be safe, the IAFF and other safety organizations recommend homeowners replace all ionization, dual sensor, and unknown alarms with photoelectric smoke alarms. To see our #1 recommendation for the best photoelectric smoke detector, jump back up to the top."
Thanks again, Dively. That gives me the information I need to move forward.
