733.05
A. Cabinet Riser for NEMA Cabinet. Furnish an aluminum riser that will
raise the NEMA cabinet approximately 12 inches (0.3 m) above the concrete
foundation. Ensure that the bottom of the riser bolts to the standard cabinet
foundation anchor bolts (not included with the riser) and the top of the riser bolts
to the bottom of the cabinet. Furnish attachment hardware for connecting the riser
to the cabinet.
Construct the riser in a minimum of two pieces such that an existing cabinet can
be raised off the foundation without disconnecting the field wiring and the riser
can be inserted below the cabinet. Furnish hardware for rigidly connecting the
riser sections together.
Fabricate the riser from 0.125-inch (3 mm) sheet aluminum with flanges on the
top and bottom to provide rigidity. Furnish mounting flanges as necessary to
connect with the controller cabinet and foundation anchor bolts. Ensure that the
outside surface of the riser has a smooth, uniform, natural finish unless controller
cabinet painting is shown on the plans. If painting is required, prepare and paint
the riser to match the cabinet.
B. Cabinet Riser for Type 332, 334 or Type 336 Cabinet. Furnish an
aluminum riser that will raise the Model 332, 334 or 336 cabinet approximately 8
inches (0.2 m) above the concrete foundation. Ensure that the bottom of the riser
bolts to the standard cabinet foundation anchor bolts (not included with the riser)
and the top of the riser bolts to the bottom of the cabinet. Furnish attachment
hardware for connecting the riser to the cabinet. Manufacture the unit to CalTrans
specifications. Ensure that the outside surface of the riser has a smooth, uniform,
natural finish unless controller cabinet painting is shown on the plans. If painting
is required, prepare and paint the riser to match the cabinet.
Furnish materials according to the Department’s Qualified Products List (QPL).
733.05 Flasher Controller. Furnish solid-state flasher that complies with
NEMA TS-1, Section 8, and have two circuits, each rated at 10 amperes. Furnish
a cabinet that conforms to applicable requirements of 733.03.A, except that the
following items are not required: a small door-in-door (police door), shelves, and
a fan. Ensure that the cabinet size is not less than 12 inches (300 mm) high by 10
inches (250 mm) wide by 6 inches (150 mm) deep. Furnish cabinets that are
designed for pole mounting with a 1-1/2 inch (38 mm) or larger conduit opening in
the bottom. Ensure that the auxiliary equipment includes: on-off power switch
with integral 20-ampere circuit breaker, lightning protection devices on incoming
power lines, interference filters, terminal blocks, and a ground bus bar.
Furnish materials according to the Department’s Qualified Products List (QPL).
733.06 Controller, Master, Traffic Responsive.
A. Description. The traffic responsive master controller is one component of a
distributive processing, traffic responsive, control, and monitoring “closed loop”
system. The master controller’s principal operational task is to select and
implement traffic signal timing plans in response to both actual traffic conditions
or time based events. The master controller monitors, in real time, local
intersection activity, and overall system performance, reporting failures and status
conditions to the Remote Monitoring Station.
