OUTLET BOXES. Where flush-mounting switches
are used, single-gang outlet boxes will be installed. In
installing such boxes, make certain to place them in a
location that permits personnel to operate the switch
while communicating via the room speaker. The normal
height (above the finished floor) for room switches is
approximately four feet, while speakers are normally
placed at a height of about seven and one-half feet.
SOLDERING INSTRUCTIONS
SOLDER.
Do not use acid-core solder or acid paste.
Make all solder connections with standard
60/40
resin-
core radio solder. Do not apply excessive heat. Solder-
ing irons or guns from 75 to 200 watts will provide
ample capacity.
GROUNDS.
Do not connect cable shields to earth
ground or to convenient metal objects.
It
is important to
connect cable shields only as shown in the wiring
diagrams.
