Question

smoke detector position


are smoke detectors any less effective when they are positioned high on a wall than when they are on the ceiling?

Generally you would want them at the highest point in the room. That is where the smoke is going to go, but if they are all flat ceilings, the code around here is that they have to be installed on the ceiling or within 1' of the ceiling.

definitely within a foot. but i was thinking more because of the detector facing sideways rather than down

Valid question but if you think about it, if there was smoke/fire it would be unlikely that it would originate directly under the detector. The smoke would rise to the ceiling, then spread out either completely engulfing the ceiling mounted detector or entering the detector from the side.

If it was mounted to the wall, the smoke would spread either engulfing it or entering from the face, top, bottom, or sides. Really no difference.

If you are still unsure read the booklet that comes with the detector. Some may have restrictions, but I haven't run into them.

I had an extra one and had none mounted in the kitchen at the time. I set it on top of the kitchen cabinets. Worked fine there. It would go off even before we saw any smoke. Wife used it as a way to tell when something was done. LOL Just kidding!!!!!! But it was easy to move to another location when it did go off due to the oven putting out a little smoke. Kinda handy.
