Installation and Maintenance Instructions
An Overview of the Model 371LED-120
Federal Signal Model 371LED-120 warning light incorporates
an array of high power LEDs, a custom optic, and a rotating
reector to focus a beam of light that rotates 360 degrees within
|a plastic dome.
The Model 371LED-120 features a impact-resistant plastic dome.
The Model 371LED is available in ve colors: amber, blue, clear,
green, and red. The dome-and-ring assembly screws on, providing
access to the interior of the light. The base features textured black
powder paint for greater corrosion-resistance. Wiring can be routed
through the pipe-mount opening in the bottom of the light or the
two side knockouts can be used for side entry wiring. Installation
can be surface or 1-inch NPT pipe mount.
An optional reector is available that reects the light beam at
22.5 degrees from the vertical orientation for overhead mounting
and other applications. See Figure 1 on page 7.
Also available is an optional wall-mount bracket. The LHWB
wall-mount bracket can be used to mount the Model 371LED. For
surface mounting on solid substrates, the separately purchased
Model 371BRCKT three-point surface-mount bracket is available.
Unpacking the Light
After unpacking the light, examine it for damage that may
have occurred in transit. If the light has been damaged, do not
attempt to install or operate it. File a claim immediately with
the carrier, stating the extent of the damage. Carefully check all
envelopes, shipping labels, and tags before removing or discarding
them. Disposal of all shipping materials must be carried out in
accordance with national and local codes and standards. If any
parts are missing, please call Federal Signal Customer Support at
708-534-4756.

Mounting the Light
The Model 371LED-120 light is designed for mounting on a at
horizontal surface or on a 1-inch NPT pipe. For surface mounting on
solid substrates, the separately purchased Model 371BRCKT surface
mounting bracket can be used. If conduit side-entries are to be used,
disassemble the light as described in “Wiring the Light” on page 11
and remove one or more knockouts with a blunt tool before mounting
the light. Use a le to remove excess ash around the knockout.
INSTALLATION NOTE: To avoid moisture buildup within the
light enclosure in highly humid areas where condensation is present
in the conduit system, duct sealant or other suitable materials are
recommended for sealing the wires/conduit entrances.
Pipe Mounting the Light
Attach the light to the 1-inch NPT pipe by threading the light
clockwise on the pipe (Figure 2). For information on making the
electrical connections, see “Wiring the Light” on page 11.

Surface Mounting the Light
To mount the light on a at surface:
1. Using the gasket as a template, scribe four drill-position
marks on the mounting surface (Figure 2).
Drill a 9/32-inch (7.1 mm) diameter hole at each of the
2.
outside drill-position marks for mounting.
Drill or punch a 1-3/8 inch (34.9 mm) diameter hole at the
3.
center drill-position mark for the wire entry.
Attach a suitable 1-inch NPT hub or connector to conduit
4.
entrance in bottom of light. For Type 4X/IP66 applications,
the hub or connector must be suitably rated (Myers®
STTTB-2 or T&B® H100-TB hubs are recommended.)
Set the light on the gasket and attach it to the mounting
5.
surface with the provided 1/4-inch screws and washers.
For information on making the electrical connections, see
6.
page 11.
Installing the Optional 22.5-Degree Reector
The light is shipped from the factory with the standard reector
that creates a horizontal lightbeam that is 90 degrees from the
vertical orientation. An optional reector is available that reects
the light beam at 22.5 degrees from the vertical orientation (see
Figure 1 on page 7 and “Table 4 Accessories” on page 15).
To replace the standard reector with the 22.5-degree reector:
1. Disconnect power to the light.
See Figure 3 on page 10. Remove the dome assembly by
2.
grasping the die-cast ring attached to the dome and turning it
counter-clockwise.
Loosen the two Phillips screws that retain the reector.

Wiring the Light
SHOCK HAZARD
To avoid electrical shock hazards, do not connect wires while
power is applied.
The Model 371LED comes assembled from the factory with two
color-coded leads for wiring to a junction box. If desired, the
factory leads can be removed and the supply connections can be
directly made to the terminal block located on the bottom of the
light base as described below
Disassemble the light (Figure 4 on page 12):
1.
a) Remove the dome assembly by grasping the die-cast ring
attached to the dome and turning it counter-clockwise.
Remove three #10 Phillips screws that secure the LED /

If you are using conduit side-entries, attach a Myers®
2.
STTTB-2 or a T&B® H075TBH 3/4-inch NPT conduit hub
with a 3/4-inch NPT close nipple (both installer-supplied)
to the housing and securely tighten the hub. When side
entries are used, the bottom 1-inch NPT conduit entry must
be plugged with a threaded plug (installer-supplied). (See
“Table 4 Accessories” on page 15.)
Route the supply wires (10 AWG to 16 AWG) into the light

the ends of the power leads. Connect the wires to the
terminal block by inserting the stripped ends of the wires
into the connectors as far as they can travel.

Maintaining the Model 371LED-120
Establishing a regular maintenance schedule for the Model
371LED-120 extends the life of the light and ensures safety.
Periodically check that the light operates properly. Also, inspect
the dome for cracks, crazing (hairline cracks), discoloration, and
