Mount AP433e above a Suspended Ceiling (Plenum)
Use the optional T-bar box hanger mounting kit to mount the AP433e above
suspended ceiling T-rails (Figure 12, AP433e Mounted above a Suspended
Ceiling Face Down). The installation attaches the T-bar box hanger to the ceiling
rails and then the AP433e attaches to the T-bar box hanger. Note that an AP433e
mounted above the ceiling has about 2-3 dBm less RF coverage than an AP433e
mounted under the ceiling.

The AP433e with the metal enclosure exposed meets the requirements for fire
resistance and low smoke-generating characteristics required by Section 300-
22(C) of the National Electrical Code (NEC) for installation in a building’s
environmental air space.

You may need to modify thicker tiles to support this installation.
Warning!
Any Fast Ethernet (FE) cables installed in air-handling spaces should be suitable
under NEC Article 800.50 and marked accordingly for use in plenums and air
handling spaces with regard to smoke propagation, such as CL2-P, CL3-P, MPP
(Multi Purpose Plenum), or CMP (Communications Plenum). Use Ethernet cable
that meets the requirements for operating in plenums and environmental air space
in accordance with Section 300-22(C) of the NEC.
