GENERAL DESCRIPTION
The SAFETSIGN, both single and double, consists of a sign with two hinged outer
panels which close over a center panel or open to display a sign face. The display
interval can be controlled manually, by a sensor device, or a remote signal, or with
a conventional clock timer. More than one sign may be operated from a single
electrical source.
SIGN FACE
The sign face is composed of reflective sheeting or non--reflective film. Message,
border, and background color conforming to the manual of uniform traffic control
devices.
OPERATION
SAFE T SIGN is designed to function under
a wide range ct environmental conditions
including rain, snow, wind, and temperatures
from -40° F to 140° F. Heavy ice or snow
accumulations may temporarily prevent
sign operation, but will not damage the
motor or drive mechanism. Sign will not be
dambged if the side panels are manually
forced open or closed with the normal 180°
operating range. Under power, the opening
or closing time is six seconds or less. An
optional heater is available for areas where
ice and snow accumulations are frequent.
SIGN MOUNTINGS
SAFFTSIGN may be mounted in various
ways. Typical configurations with single
message signs are shown on the following
page. Two or more double message signs
can be mounted side by side on a main frame
for a longer length.
CONSTRUCTION
SAFETSIGN is primarily constructed from
6061-T6 aluminum components keeping
weight at a minimum and yet providing more
than adequate structural strength.
DRIVE M ECHAN ISM
Drive mechanism consists of a chain drive,
cam driven, self-locking device with positive
drive on both cycles with spring override.
Drive motor is 11S VAC, 3 amp, magnetic
break, nonreversing, gear reduction type,
developing a minimum torque of 140 lbs.
at 6 - 8 Rpm, and has direct drive from
output shaft to operating cam. All drive
mechanism parts are enclosed in a corrosion
resistant box. Sign frame, back panel,
louvers, top pan, and cover are constructed
from aluminum.
