5. Secure the housing to the T-bar.
Clamp the housing to the T-bars by snapping a T-bar
clip (c) over the raised edge of the housing and the
T-bar. Center this clip along the edge. Repeat for
each side of housing.
6. Connect one end of the safety chain to the
housing, with opposite end secured to a
ceiling member.
Wrap safety chain (d) around a strong ceiling
member while attaching it to itself using an S-hook
(e). Using a second S-hook (e), attach the other end
of the chain to one of two eyelets on the housing.
!
WARNING!
Keep chain as taut as possible! Close
ends of each S-hook!
DO NOT use sprinkler or fire control
system when securing the safety
chain!
7. Feed cables through a hole in the side of the
housing.
Feed video and multiconductor cables through one
of the two holes in the side of the housing and
reinstall the adjacent ceiling tile. The housing is now
ready for chassis installation (go to “Chassis
Installation,” page 2-8).
Pendant Mount Installation
The following methods show you how to mount the
dome’s base directly to the surface of a hard ceiling
(sheet rock) or I-beam using a pipe as a pendant.
Standard Pendant Mounting
This procedure explains how to mount the dome’s
housing to a section of pipe extending downward
from the ceiling. After completing this procedure,
go to page 2-8 for chassis installation.

Remove the flange and drill four .64cm (1/4”) holes
to required depth.
For each hole, screw two nuts onto the anchor bolt
provided, with two threads of the second nut
extending over end of bolt (b) to prevent damage to
bolt threads.
