Someone could make a lot of money making smokes that come in various colors.

I agree. This is not the first time I've had this request.

Again, if they made the enclosures so that one could remove the electronics and paint... :roll:

Have you ever seen a faded white ceiling?

:cool:

I have seen many faded (yellow) smoke detectors. I had one in my house for 22 years I finally changed it last year- it worked but it was almost totally yellow-- no we don't smoke.

Some brands of commercial smoke detectors turn yellow even in smoke free workplaces. :mad:

But smokes have a 10 year life expectancy.

There was a component in the plastic that reacted & turned yellow in the presence of fluorescent lighting. The closer the smoke detector was to the fluorescent tube, the yellower it got. Smokes on the same job in unlit closets remained white.....

Planned obsolescence?

I imagine the 'Do Not Paint' is part of the listing because the risk exists of partially or completely blocking the vents with a sloppy paint job.

A flush mount smoke detector would be a bad idea. Air flow is the reason. The detection response time would be slower. This means a higher smoke concentration in other areas before the flush mount unit would trigger.

This is based on test results at UL in the early 60s. This was not based on a flush mount test, but on comparisons of different smoke detectors, their air flow, and response times.

I dont think either of the links provided by Bob or Marc show a truely "flush mount" design. They both protrude to some degree from the finished surface. I also dont think a company like Kidde would throw a product onto the market like that without intensive testing of design and function.

I removed the guts and painted a smoke in my house. It was a system type smoke and easy to do, though.

Let the heckling begin......
