A New Fix For Ionization-type Smoke Alarms?

Tue Jul 26, 2011 3:06 am

As I have stated in a previous thread, I have been opposed to ionization-only smoke alarms due to their ineffectiveness at detecting slow smoldering fires compared to photoelectric or dual sensor alarms.

However, it looks like Universal Security Instruments (USI, the #3 player in the smoke alarm industry behind Kidde and BRK/First Alert) has come out with a new patented ionization technology known as IoPhic:
http://www.universalsecurity.com/iophic.htm

According to USI, the new IoPhic models are more effective than dual photoelectric/ionization models at sensing both fast flaming as well as slow smoldering fires, yet costs less than competing photoelectric-only models. USI also claims it is less prone to false alarms than a standard ionization smoke alarm.

This looks like it could be a good solution, however, as with any claims by a company, it should be taken with a grain of salt. Also, some will still be uncomfortable with the americium that is used in any type of ionization alarm. Since this is a closed patent by USI, neither Kidde nor BRK are allowed to come up with competing models using the same technological improvements, otherwise it would violate USI's patents.

For our new house in Gilbert, since it will have Kidde alarms, we just bought a Kidde PI2010 dual-sensor hardwire alarm (brands must match when interconnecting). However, the house that my brother lives in has USI alarms (one photoelectric, the rest ionization), and maybe if one of those ionization alarms fails or breaks a new IoPhic model would be an option.

What does anyone think about this?

I think that you should have an assortment of available alarms to keep your family safe. I do not care for the Ionization alarms myself, as I previously stated. I have both photo-electric and Ionization types. One cannot be too careful when it comes to fire, especially with children in the home.

One thing I am curious about is whether or not these USI IoPhic alarms will get approval in the four states that require photoelectric or dual-sensor alarms. Maine, Massachusetts, and Vermont require photoelectric, while Iowa requires dual-sensor. I think someone on YouTube should try the Aquarium Test on one of these alarms to see if it works as advertised.

And for heaven's sake, replace your batteries in your detectors once you have them. There have been many fires in homes where there were smoke detectors and either the batteries were dead or the people in the home have disconnected them!

Preferrably, buy a lithium battery where you don't have to replace it for many years.
