INSTALLATION
This installation should be made by qualified service
personnel and conform to all applicable local codes
Warning: Do not mount the Parapet Mount
in an inverted position.
7.1
Wind Loading
The following information on Effective Projected Area (EPA)
is provided to assist the installer in making sure that the
installation of the Parapet Mount will meet local codes with
regard to wind loading. Other dimensions that may be
needed can be found in the instructions for the individual
dome or housing.
MT9230 Parapet Mount
EPA = 1.15 sq. feet
In general, it is recommended that the Parapet Mount and its
associated camera unit not be installed in locations where
wind speed is expected to exceed 100 mph (including gusts)
or where a total wind load of 60 lb. (27 kg) is expected
unless extra support and stabilization are provided.
If additional stabilization of the Parapet Mount is required or
desired, it may be achieved using guy wires and a stainless
steel eye bolt (not included). An attachment point for the
eye bolt is provided at a threaded hole with 1/4" - 20
threads. Remove the cap screw (see Figure 1) installed at
the factory and replace it with a stainless steel eye bolt.
Avoid too much tension in the guy wires so as not to
increase the downward load on the Parapet Mount beyond
the rated load.

7.2 Mounting Hardware
Mounting hardware has not been included. The mounting
hardware must be selected to work with the type of wall to
which the unit will be mounted.
CAUTION:
a. For a secure installation use a minimum of six 3/8
inch (10 mm) diameter fasteners, three on each
side of the mounting bracket. Use stainless steel
fasteners.
b. If bolts are used, they should extend through the
mounting surface and be secured with flat washers,
lock washers and nuts on the opposite side. Each
bolt must have a minimum pull-out strength of 600
pounds (275 kg).
c. If studs are used, they should be anchored in
concrete or welded to a steel backer plate. Each
stud must have a minimum pull out strength 600
pounds (275 kg).
d. If the wall mount is attached to wood or to a
blind structure (with no access to the rear), each
fastener must have a minimum pull-out strength
of 600 pounds (275 kg).
7.3 Tools Required
• Standard screwdriver.
• 9/16 inch wrench or socket.
• 16 mm wrench or socket (if using metric fasteners).
• 5/32" or 4mm Allen wrench (if wind load stabilization is
desired).
• Thread sealant or pipe tape.
• Other tools as needed for preparing the mounting
surface.
7.4 Parapet Wall Installation
1.
Determine the location of the unit on the wall. Choose
a location to allow the mounting bracket to be placed as
close as possible to the top of the wall. This will allow
the best chance for the dome to clear the wall when it is
swung into position and for maintenance.
CAUTION: Allow enough room below the
mounting bracket for routing the camera and
control cables.
2.
Using the wall mounting bracket as a template, position
the bracket in the desired location and mark the hole
locations on the wall. (see Figure 2). Use a minimum of
six fasteners (three fasteners for each side of the
mounting bracket).
3.
Prepare the mounting surface for the type of fasteners that
will be used by drilling holes or mounting anchors, etc. as
required.
4.
Apply a good quality sealant around each hole, anchor or
stud at the mounting surface (see Figure 2).
5.
Install the mounting bracket and tighten all fasteners
securely.
6.
Insert the pipe arm into the mounting bracket until it
bottoms.
7.
Feed all electrical and control cables through the pipe
arm and out the bottom of the mounting bracket. This
