I have a situation where the customer purchased 1142 access points and now decided that they don't want them mounted below the ceiling tile (on the grid). This is a college housing environment so they've had issues with things being damaged, like smoke detectors and exit signs.
I haven't done the survey yet but I just want to make sure that there aren't any issues that might be a show stopper. Like putting this access point above ceiling tile and causing a fire code issue.
You should be good to go with the Ap's mounted above the ceiling tiles :) Keep them away from the students.
The 1140 series access point complies with UL 2043 for products installed in a building's environmental air handling spaces, such as above suspended ceilings.
Hope this helps!
