Wall Attachment Requirements - AT&T Merlin II Installation And Maintenance Manual

WALL ATTACHMENT
REQUIREMENTS
2-4 Preinstallation Requirements
The customer should have a backboard mounted at the
control unit site. If one is not in place, you may need to
attach a backboard to the wall. The backboard should
meet these specifications:
It should be made of 3/4-inch thick plywood.
It should be 4 feet wide by 2 feet high in order to
accommodate a basic control unit with an expansion
carrier and jack field. If ample wall space is available,
use a backboard that is 4 feet by 4 feet, regardless of
the system's size. This size provides enough space for
future expansion.
It should be attached to the wall with hardware that has
a combined pull-out force of at least 500 pounds.
Determine the type of mounting surface on which the
board is to be mounted, and refer to Table 2-1 for
recommended hardware.
