C Positioning ceiling and wall sensors
Combining external sensors is ideal for complete coverage of odd sized or oversized rooms with or without non-
reflecting or obstructing walls. Use the following guidelines when installing ceiling and wall sensors:
– Mentally divide an odd-shaped room into sections as shown. The receiver and ceiling sensor should cover
the larger sections of the room and the wall sensor should cover the alcove or smaller section.
– For larger sized rooms greater than 2500 sq. ft. we recommend using external wall sensors only (up to six
wall sensors maximum) for optimum room coverage in IR challenging room environments.
– Use a piece of tape to mark a spot on the ceiling that is centered within one half of the large section of the
room – this is where you will install the ceiling sensor
– Use a piece of tape to mark a spot for each of the wall sensors. The spot you choose should be:
– on a wall, as close to the ceiling as possible
– in a position that can “see” the entire section
Ceiling sensor and wall sensor placement conditions:
– odd-shaped rooms with alcoves, bays or sheltered areas
– large sized rooms greater than 50’ x 50’ (2500 sq. ft.) and less than 50’ x 60’ (3000 sq. ft.)
– rooms with obstructions, dark-toned walls and ceilings
– rooms with greater than 50% window to wall area
