Federal Signal Corporation FL3SF Series Instruction Sheet

Check the parts received against the appropriate kit
contents list at the end of this sheet before performing
the installation procedure in this sheet.
A. INSTALLATION.
1. Drill or punch a 1-5/8" ( 41 mm) hole at the floodlight
mounting location.
2. Slide the mounting base from the pole. Set the
mounting base at the mounting location, making sure that the
base flange is centered in the 1-5/8" hole that was drilled in
step a.
3. Using the mounting base as a template, scribe four
screw position marks on the mounting surface.
4. Replace the mounting base on the pole. Thread the 8-
32 phillips pan head self-tapping screw into the hole in the end
of the pole, as shown in figure 1.
5. If the hex head mounting screws (supplied) are to be
threaded into the mounting surface, drill four no. 8 holes at
the position marks and tap the holes with a 1/4" x 20 tap. If
the telescoping mount is to be secured with the supplied
mounting screws and uses supplied 1/4"-20 nuts, use an H
(.266") drill to drill four holes at the position marks.
6. If the electrical power leads will not be accessible
after the base is attached to the mounting surface, proceed
directly to step 7. However, if the power leads can be connected
after the assembly is mounted, mount the base using the four
1/4"-20 hex head screws and lockwashers supplied.
7. Attach the floodlight and bumper mounting bracket
to the flange on the pole using four
1/4"-20 hex head screws and lockwashers. Make sure that the
bumper bracket is secured between the yoke and the flange as
shown in figure 1. In addition, ensure that the end with the
longer distance between the mounting holes and the bend faces
forward, as indicated in figure 1. Thread the locking handle in
the mounting base and tighten it to lock the pole at the desired
height.
8. Insert the snap bushing into the hole in the center of
the yoke. Press one rubber bumper into each of the two holes
in the bumper mounting bracket, as indicated in figure 1.
9. Route the floodlight power cable through the bushing
that was installed in step 8 and out the end of the pole. If
necessary splice additional 12AWG, or larger, wire to the end
of the cable. Two conductor cable with 12AWG, or larger,
conductors may be used, if desired. Insulate all splices.
Connect the power cable to the power source.

NOTE
FOR
10. If necessary, attach the floodlight/telescoping mount
assembly to the mounting surface using four 1/4"-20 hex head
screws and lockwashers. Use 1/4"-20 hex nuts also, if required.
B. ADJUSTMENT.
During and immediately after or before operation,
lamp housing is extremely hot. Gloves are recom-
mended for aiming.
Vertical aiming of the floodlight is accomplished by
rotating the locking lever downward and tilting the unit to the
desired position. Lifting the locking lever should then lock the
floodlight in position. However, if the locking lever does not
lock the floodlight into position, proceed as follows:
1. Loosen the set screw in the locking lever hub and
disengage it from the yoke hub.
2. Rotate the locking lever assembly downward so that
the aligning pins engage the next set of holes in the yoke hub.
3. Rotate the locking lever upward to check that the
floodlight locks in position. If the floodlight does not lock,
repeat steps 2 and 3.
4. Retighten the set screw in the locking lever yoke.
