Ceiling sensor placement
1. 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 ceiling 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 ceiling sensor.
Assessing the individual characteristics of the environment is critical to achieving the best performance.
Poor coverage planning can dramatically reduce the performance of the system.
a. DO NOT mount the ceiling sensor or wall sensors in direct sunlight as it will greatly reduce performance.
b. The ceiling sensor must have a clear view of the coverage area and must be mounted parallel to the
floor to function optimally (figure 1). If drop lights are used in the room, wall sensors may be a better
option. Or, a drop mount* may be used to lower the ceiling sensor.
