Occupancy sensors in door frame

I have a school system that is replacing all of the toggle switches with occupancy sensors. Almost all of their switches are installed in the frame between the door and sidelight.

Anybody installing sensors in these locations? The senors are 1.68" wide. the frame is 2" outside to outside.

They understand the limitations of this type of sensor. I am only concerned with acceptance by the electrical inspector and code official.
 
Door sensors is the intent to be used for security system or fire protection of opening or closing doors. There exit many different regulations for user in occupancy of different types for instance 'I' Institutional as in health care where egress of a fire for safety or ensure closure between zones between building with multiple occupancy or 'M' mercantile where they may be used in conjunction with badge readers
 
but how are the existing toggles in the door frame ?

I don't think OP has "door sensors" but rather toggle switches somehow installed in the door frame. He wants to replace their function with occupancy sensors that turn on lights when sensing occupants instead of something (that can be lighting, security, egress, etc.) that is triggered whenever the door opens.

If I am correct on this one suggestion I have is to leave the switches and install occupancy sensors on the ceiling or wherever else works. Can even put them in series with the occupancy sensor if you have a need to darken a room while occupied - which does happen in classrooms of a school.

I think you read the op correctly but for some reason you chose to ignore this part....

are these regular wall switches installed in a frame without a junction box behind them?

a code compliant solution is a wireless pico switch, and a lutron ceiling mounted occ sensor.
the pico will fill in the hole, and have no wiring.

you'll have local control of the lights, and occ sensor for energy code compliance,
depending on what that looks like for you.

you can also do it with a nLight npod device, and have multi scene control if
you need that. you'll need to fish a cat 5 down the frame.

i'm preferable to the nLight system, but lutron will be cheaper.
