Installing the housing
With the surface prepared and/or the mount now installed, install the housing.
To install a flush-mount housing, see Figure 13 on page 18 and do the following:
1. Remove either conduit knockout (side or top) in the housing.
2. Hold the housing up near the housing passthrough of the mount or cutout.
3. Connect a steel safety cable, if required by local codes.
a. Obtain a steel safety cable of 0.125 in. (3 mm) maximum diameter that complies with local codes.
b. Snip off the nipple that opens access to the safety cable clip.
c. Feed your safety cable through the exposed hole.
d. Secure one end of the safety cable into the safety clip surrounding the exposed hole inside the housing.
e. Secure the other end of the safety cable to the building superstructure.
4. Feed the facility cables through the conduit hole of the housing. Allow enough cable length to make
connections. Figure 9 on page 13 shows how the cables run through the housing.
5. Attach the housing to the mount or ceiling by screwing the housing tabs open and down.
CAUTION: All flush-mount installations must have a fan. If you are installing a flush-mount housing that does not
have a fan, see
Fan installation on page 19.
CAUTION: For safety, the mounting surface, hardware, and procedure used for securing the dome must support
the weight of the dome, mount (if used), cables, and any structural or environmental vibration
according to local codes. See
Table 1 on page 4.
