The top and bottom opening of each signal head section includes
a circular 72-tooth serrated connection (2-inch nominal I.D.)
providing positive positioning and alignment of the signal head
sections and the complete assembly in 5-degree increments.
The connections, when completely assembled and tightened in
accordance with manufacturer recommendations, prevent
rotation or misalignment of the signal head as well as
misalignment between sections.
The serrated area starts outside of the 2-inch hole and is at least
⅛-inch wide. The teeth have a minimum depth of 3/64-inch
between peaks and valleys; are well-defined, free from burrs,
irregularities, or other imperfections; and provide positive locking
with the grooves of mating sections, framework, and brackets.
The serration on the top circular connection of a signal section
has a valley at the 0-degree position, aligned perpendicular to
the front of the section; the serration on the bottom circular
connection has a peak at the 0-degree position, aligned
perpendicular to the front of the section.
Connections are such that the front of each section assembly of
a multi-section signal can be aligned within one degree.
Signal sections include at least two latch pads and manual
stainless steel latching devices that are captive, or nonremovable.
All fastening hardware, such as hinge pins, door latching
devices, washers, screws, and fittings are passivated stainless
steel type 316 or 304.
By signing this form, the applicant declares that he/she has read and
understands the provisions of Section A650 of the FDOT Minimum
Specifications for Traffic Control Signals and Devices and all implemented
modifications. The requirements listed on this matrix are derived from Section
A650, and are the basis for determining a product’s compliance and its
acceptability for use on Florida roads.

Requirement
All signal head assemblies are permanently marked with the
manufacturer name, part/model number, and date of
manufacture.
Each signal section has four back plate mounting attachment
points. Each mounting point is no more than three inches from
the corner of each section. Back plate attachment points are
designed to accept #10-16 x 3/8 inch or 10-24 x 3/8 inch screws.
Each signal section is designed to prevent the accumulation of
standing water within the assembly.
All tri-stud washers are passivated stainless steel type 316 or
304; washers used between signal sections are 3/32 inch
minimum thickness. Tri-stud washers used to attach the top
section of a 5-section cluster assembly to the multi-signal bracket
and the multi-signal bracket to the bottom four sections are a
minimum of 3/8-inch thick.
All sections comprising a single multi-section vehicular signal
assembly are rigidly and securely fastened together forming a
dust, insect, and weather-resistant unit with no distortion of the
tri-stud washers.
Each signal section includes at least two integral hinges, with
captive hinge pins of adequate strength for mounting the door.
Signal section doors can be mounted to provide either left or right
swing.
Door latch holds the door tightly closed and the door remains
captive and secure at all times.
The inside face of the door is provided with at least four stainless
steel, type 316 or 304, clamps to secure the lens or signal
module to the door.

Door includes slotted pads that allow the door to be opened and
closed by engaging or disengaging the latching device. The
outside face of the door includes four holes equally spaced
around the circumference of the lens opening to accommodate
the attachment of a visor.
The outside face of the door provides a light-tight seal between
the visor and the door assembly. The lens opening in the door
has a diameter of 11 to 11.5 inches.
The rear of the visor has four tabs, notches, or holes for securing
the visor to a signal section door. The visor mounting method
permits the visor to be rotated and secured at 90 degrees for
horizontal signal head installations.
Visors have a minimum downward tilt of 3.5 degrees measured
from the center of the lens and are a minimum length of 9.5
inches.
For tunnel visors, the visor encircles and shields the lens 300
degrees, plus or minus 10 degrees.
If visor has louvers, visor is a full circle visor.

Section
A650-2.5
Requirement
Signal head sections include gaskets that provide a weatherproof
seal to prevent the intrusion of dust and moisture into the signal
assembly.
26
Seals are provided between the body of the signal section and
door; between the lens and the door; and between any other
mating surfaces where gaps might exist to eliminate intrusion of
dust and moisture.
27
Where gaskets meet, they are glued or sealed, to provide one
continuous length of gasket. Gasket materials meet National
Electrical Manufacturers Association (NEMA) 250 and are
constructed of weather-resistant material that has been
temperature stabilized to prevent any residue that could collect
on the internal surfaces of the signal head.
28 A650-4
Three section signal head assemblies have at least one fiveconnection terminal block; five section signal head assemblies
have at least three five-connection terminal blocks. Terminal
block connections do not require any tool other than a

attachment screws used on terminal blocks are fabricated using
non-corrosive material approved by FDOT-TERL.
30 A650-5.1
Housing, door, and visor are dull black (Federal Standard 595A37038) with a reflectance value not exceeding 25 percent as
