4.2.1.4 Plenum Mount (Above Drop Ceiling)
The MR24 can be mounted to the T-bar grid above the tiles of a drop ceiling using a 3rd party T-bar box hanger
(not included). The Erico Caddy 512A is recommended and is used in installation instruction illustrations.
Note: a UL2043-rated Ethernet cable should be used for a plenum installation.
1. Adjust the height of the T-bar box hanger crossbar to make sure there is adequate clearance between
the access point and the top of the ceiling tiles. Tighten the height adjusting screws.
2. Attach the bracket mounting clip (included with T-bar box hanger) to the center of the T-bar box hanger crossbar.
3. Attach the MR24 mount plate to the access point mounting bracket using a 6-32 screw, washer, and nut
(not included with T-bar box hanger) and the Above Drop Ceiling (Box Hanger) hole in the mount plate
(reference Mounting Template).
