4.2.3.4 Plenum Mount (Above Dropped Ceiling)
The MR14 can be mounted to the T-bar grid above the tiles of a suspended 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. Securely attach the T-rail clips on either side of the T-bar box hanger to the suspended ceiling grid T-rails.
3. Connect a grounding wire (not included with T-bar box hanger) to the grounding hole in the bracket
mounting clip and to metal building structure. A grounding wire is required to comply with the U.S.
National Electric Safety Code.
4. Attach the bracket mounting clip (included with T-bar box hanger) to the center of the T-bar box hanger crossbar.
5. Attach the MR14 to the access point mounting bracket using a 6-32 screw and washer (not included with
T-bar box hanger) and the multi-purpose mounting hole on the back of the access point (referenced on p. 7.)
