Flush-Mount Housings; Preparing The Mounting Surface - GE Security Legend IP Installation Manual

Flush-mount housings

Flush-mount and pendant-mount housings require different preparation of the mounting surface and different
installation procedures of the housings. Follow the instructions given here for flush-mount housings.
CAUTION: The flush-mount housing is for indoor applications only. Do not expose it to moisture, or the unit may
be damaged.

Preparing the mounting surface

Following are the steps for preparing the mounting surface if you are mounting the housing directly into a solid
surface that does not require reinforcement. If the mounting surface does require reinforcement, first install a
GEA-113 T-bar ceiling panel or a GEA-114 T-bar support kit. Instructions for installing the GEA-114 are
available in this manual
to the instructions that came with the panel (1052914).
CAUTION: For all installations, heed these cautions:
• Complete all installation steps before supplying power to the dome.
• To ensure proper operation of a PTZ unit, install the mount level.
• 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,
page 9.
To prepare the mounting surface, see Figure 8 and do the following:
1. Mark the position and size of the housing pass-through hole on the mounting surface. The size of the
cutout for the pass-through must be 8-3/8 to 8-7/16 in. (21.27 to 21.42 cm).
2. Following all local codes, cut the housing pass-through hole.
3. Make sure that the facility cables (Ethernet and power, and if used, alarm, relay, and analog video and
data) for the dome comply with the recommendations provided in
4. Feed the facility cables through the housing pass-through hole in the mounting surface.
• Pull enough cable to make connections. You can always cut off unneeded length later.
• How many cables you have depends upon how many alarms and relays you are connecting in
addition to the Ethernet and power cables, and whether you will be installing cables for analog
data and video. See
