Installation Considerations
Signal distance varies depending on the location of the MOSAIC FIREFLY. Those installed
above ground or through plastic lids generally transmit the greatest distance.
The material of a pit or vault lid greatly affects the transmission range. For example, a
transmitter has a greater range sending from a pit with a plastic lid than a cast iron lid. A
FIREFLY mounted under any type of lid is subject to flooding. Since water impedes RF
transmission it is best to mount through the lid using a Lid Lock.
Lids with holes of a diameter of roughly 1 ¾ inches make it possible to mount the MOSAIC
FIREFLY through the lid. This can increase transmission range significantly and protect against
loss of signal due to flooded pits. It is not recommended to install FIREFLYs under iron or
metal lids as RF performance is degraded.
Complete field installation of a MOSAIC FIREFLY takes five to ten minutes, depending on the
meter location and mounting application.
If the lid has a hole for the unit, use the Lid Lock, Lid Lock adapter, and appropriate washer.
Ensure that enough space exists between the meter box lid and the ground for the MOSAIC
FIREFLY to fit. If not, remove some of the dirt from the bottom of the meter. Do not over-
tighten Lid Locks.
Some meters may be located in such a manner that they require the addition of repeaters to reach
the mesh.
Some areas of your service territory may not have the density to warrant the use of the mesh -
your project manager will alert you to these areas where units can be placed into a drive-by
mode.
Profile data uses more mesh bandwidth and as such can require the use of additional repeaters
and/or Gateways.
The system requires ongoing maintenance - make sure to have the proper equipment and training
to maintain the system after your installation contractor leaves.
Do not attempt to repair or trouble-shoot equipment without the proper equipment and training.
