Smoke detector going off due to humidity??

[Michael Roberson]

A customer of mine today, said that his smoke detectors went off last night @ 4:00 am (with no fire thank God). He has a humidistat and he said it was at 95% relative humidity in his house at that time. He is a firefighter, so he is very fire conscious, and asked me if it was the humidity, and I have NEVER heard of anything like it...

Any imput???

Happens all the time. Here is a link to read up on.

Why would anyone have 95% humidity in their house unless they live in New Orleans? That's nuts!!!

Anything that 'unbalances' the circuitry, specifically smoke, will set the alarm on ionization. The calls I mostly get, is clients calling me about the smoke detectors in unfinished spaces, in the dead of winter. Cold air can block the particles too.
