Installation Guide
2.4.3 Above the Ceiling (Plenum) Installations
An above the ceiling installation requires placing the Access Point above a suspended ceiling and installing the
provided light pipe under the ceiling tile for viewing the rear panel status LEDs of the unit. An above the ceiling
installation enables installations compliant with drop ceilings, suspended ceilings and industry standard tiles from
.625 to .75 inches thick.
NOTE
CAUTION
The mounting hardware required to install the Access Point above a ceiling consists of:
• Light pipe
• Badge for light pipe
• Decal for badge
• Safety wire (strongly recommended)
• Security cable (optional)
To install the Access Point above a ceiling:
NOTE
1. If possible, remove the adjacent ceiling tile from its frame and place it aside.
2. If required, install a safety wire, between 1.5mm (.06in.) and 2.5mm (.10in.) in diameter, in the ceiling
space.
3. If required, install and attach a security cable to the Access Point's lock port.
4. Mark a point on the finished side of the tile where the light pipe is to be located.
Both the AP7131 and AP7131N are Plenum rated to UL2043 and NEC1999
to support above the ceiling installations. To ensure UL compliance and
proper Access Point operation within the Air Handling Plenum, the
Access Point must be installed with the bottom surface of the unit in
contact with the unfinished surface of the ceiling tile. This will facilitate
the positioning of the light pipe (described in the following pages)
through the ceiling tile.
Do not mount the Access Point directly to any suspended ceiling tile
with a thickness less than 12.7mm (0.5in.) or a suspended ceiling tile
with an unsupported span greater than 660mm (26in.). Fit the Access
Point with a safety wire suitable for supporting the weight of the
device. The safety wire should be a standard ceiling suspension cable
or equivalent steel wire between 1.59mm (.062in.) and 2.5mm (.10in.)
in diameter.
Remove the Access Point's facade and antennas before installing in an
above the ceiling orientation. The Access Point is not certified for an
above the ceiling installation with its accessories installed.
