Installing The Housing And Cables; Flush-Mount Housings; Preparing The Mounting Surface - GE Legend Installation Manual

Installing the housing and cables

There are three basic mounting styles: pendant, wall, and flush. A pendant-mount lowers a dome from a
ceiling, a wall-mount extends a dome from a wall, and a flush-mount raises a dome's bubble even with a
ceiling. See Figure 4. This document provides the instructions for all mounting styles.

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. For step-by-step instructions for preparing the surface for the
GEA-114 T-bar support kit, see
T-bar ceiling panel, refer to the step-by-step instructions that came with the panel (1052914).
For all installations, heed these cautions:
CAUTION CAUTION
• 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
To prepare the mounting surface, see Figure 5 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 (data, video, power, and alarm/relay) 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 video, data, and power cables, and if you will be installing an Ethernet cable for
flash upgrades. See
