USI IoPhic Smoke & Fire Alarm

Keep in mind that despite the word, “IoPhic” this is NOT a dual sensor alarm. It uses an ionic sensor, but modified with proprietary technology to add some of the benefits of photoelectric.

never mind.

Currently $19.22 FSSS/Prime at Amazon. Previous woot discussion (we had some fun in that thread).

Oh come on, Woot. Give us something we don’t actually need!

Just got 4 new ones from my fire department for free last month. Including batteries. Granted they’re not this model, but they work, and they were free.
