The Ceiling Mount Accessory is an optional accessory that allows CEL-FI QUATRA 4000 and CEL-FI QUATRA EVO
Coverage Units to be installed in suspended ceilings. The ceiling tile mount consists of two bracket halves that slide
together and secure using set screws, allowing the mount to adjust to different suspended ceiling grid sizes.

Lift the CU and Ceiling Mount Accessory assembly through the
ceiling opening and place it on the grid where it will be installed per
measurement in previous step.
The Ceiling Mount Accessory weight should rest only on the
grid frame, and no weight should be on the ceiling tile. Two
hanger wires or similar safety tethers are recommended, in case
the ceiling grid or mount should ever fail. Follow local building
requirements where necessary.
Connect the category cables (from the Network Unit) and server
antenna or server antenna coaxial cable to the CU.
Now secure the CU to the Ceiling Mount Accessory using the two
supplied ¼-inch Washers and ¼-20 x 5/8-inch Screws.
Using a suitable ladder or lift, remove a ceiling tile that is adjacent to
the tile where you wish to mount the CU. Measure the ceiling tile grid
width as shown in the diagram above.
