Positioning a ceiling sensor
A ceiling sensor is designed to ‘see’ the entire room at once, and so can often fill in any gaps in reception by the
main receiver. Use the following guidelines when installing a dome sensor:
Mentally divide the room in half, with the main receiver contained within one half
Use a piece of tape to mark a spot on the ceiling that is centered within the other half of the room -- This is
where you will install the dome sensor
Position ceiling sensor on
the ceiling, centered in
the half of the room
opposite the receiver

Ceiling sensor placement
Single ceiling sensor placement conditions:
– walls and floors light colored (white or beige)
– less than 50% window to wall area
– rooms no larger than 50’ x 50’ (2500 sq. ft.) typical
– rooms without obstructions

Planning sensor placement
Your FrontRow Pro receiver has a powerful built-in sensor -- often sufficient to serve your entire classroom. The
walls or design of some classrooms may not allow for the direct transmission and reflections of infrared light that
your active learning system relies on. That’s why it’s a good idea to plan for external sensors.
