Relocating A Smoke Detector


The job I am talking about, involves installing a return air box, in the hallway. Problem is, the only viable location for the box is where the smoke detector is. So, the thought is we need to move the smoke detector.

My question is, what would be a good place to reset it. On a wall ? further down the hallway, further from the bedrooms? Closer to the bedrooms? There are already smoke detectors in the bedrooms in question.

Anyways, I was hoping somebody could give me an idea of a decent place to reset the smoke detector, as code requires a 3' distance from the return box.

Closer to the bedrooms should be OK. I believe code is one detector outside the vicinity of the bedrooms. But has to be more than 3' from a bath door.

There's code requirements and then there's manufacturer requirements.
Check the model number and download their installation requirements.
There are limits as to how close you can be to wall/ceiling intersection.

Smoke should not be installed closer than 3' from any supply air diffuser or return vent.

2015 IRC:

R314.3 Location.
Smoke alarms shall be installed in the following
locations:
1. In each sleeping room.
2. Outside each separate sleeping area in the immediate
vicinity of the bedrooms.
3. On each additional
story of the dwelling, including

basements
and habitable attics and not including crawl
spaces and uninhabitable
attics. In dwellings or dwelling
units
with split levels and without an intervening
door between the adjacent levels, a smoke alarm
installed on the upper level shall suffice for the adjacent
lower level provided that the lower level is less than
one full
story below the upper level.
4. Smoke alarms shall be installed not less than 3 feet
(914 mm) horizontally from the door or opening of a
bathroom that contains a bathtub or shower unless this
would prevent placement of a smoke alarm required by

Section R314.3.


As others said, manufacturer's listing will override the code. "Immediate vicinity" is somewhat up to your inspectors discretion, so check with him/her if you think it'll be an issue.
