Installation and Maintenance Instructions
Model 371LED-120 Rotating Light
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
reector 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.
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 9 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 1). For information on making the
electrical connections, see “Wiring the Light” on page 9.

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 1).
2. Drill a 9/32-inch (7.1 mm) diameter hole at each of the
outside drill-position marks for mounting.
3. Drill or punch a 1-3/8 inch (34.9 mm) diameter hole at the
center drill-position mark for the wire entry.
4. Attach a suitable 1-inch NPT hub or connector to conduit

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.)
5. Set the light on the gasket and attach it to the mounting
surface with the provided 1/4-inch screws and washers.
6. For information on making the electrical connections, see
below.
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
1. Disassemble the light (Figure 2 on page 11):
a) Remove the dome assembly by grasping the die-cast ring
attached to the dome and turning it counter-clockwise.
b) Remove three #10 Phillips screws that secure the LED/
motor module to the housing.
c) Remove the LED/motor module.
d) If preferred, remove the factory-supplied leads from the
terminal block.

2. If you are using conduit side-entries, attach a Myers®
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 14.)
3. Route the supply wires (10 AWG to 16 AWG) into the light
housing.
4. Strip a maximum of 0.28 inch (7 mm) of insulation from
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.
5. Tighten the clamping screw. The maximum tightening
torque is 7.0 in-lb (0.8 N•m).
6. Connect the earth ground to the terminal block.
7. Reassemble the light and test it for proper operation.

Safety Messages to Maintenance Personnel
Listed below are some important safety instructions and
precautions you should follow:
• Read and understand all instructions before operating this
system.
• Any maintenance to the light system must be done with the
power turned off.
• Any maintenance to the light system must be performed by a
trained electrician in accordance with NEC/CEC Guidelines
and local codes.
• Never alter the unit in any manner. Safety may be endangered
if additional openings or other alterations are made to units.
• The nameplate, which contains cautionary or other information
of importance to maintenance personnel, should not be
obscured.
• If the dome is damaged in any way, the complete dome
assembly MUST be replaced.
• After performing any maintenance, test the light system to
ensure that it is operating properly.
Failure to follow all safety precautions and instructions may result
in property damage, serious injury, or death.
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
other defects.
The threaded dome ring joint should be well lubricated with
petroleum or a soap-thickened mineral oil. If corrosive products
have accumulated on joints and cannot readily be removed with
solvents, the parts should be discarded and replaced.
