• Read and understand all instructions before installing or operating this equipment.

• Do not connect this light to the system when power is on.

• After installation, ensure that all set screws and threaded joints are properly tightened.

• After installation, test the light system to ensure that it is operatng properly.

• After testing is complete, provide a copy of this instruction sheet to all personnel.

• Establish a procedure to routinely check the light system for proper activation and operation.
Failure to follow all safety precautions and instructions may result in property damage, serious

injury, or death to you or others.

A. Unpacking.

After unpacking the unit, examine it for damage that may have occurred in transit. If the
equipment 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 destroying them.

B. Mounting.

The Model 131 is supplied ready for mounting on 1/2-inch pipe, as shown in figure 1. The
lights are UL listed for indoor and outdoor use. If the light is used outdoors, it MUST be
mounted with the base down and the dome up.

Mounting hardware and installation details are left to the installer.

NOTE

To ensure secure mounting, tighten the fixture onto the pipe to a MINIMUM torque of

5 ft.-lbs. (6.8 N m).

C. Electrical Connections.

WARNING

Do not connect wires when power is applied.

1. AC Models.

The Model 131 is supplied with three leads, one black, one white, and one green/yellow lead
for the AC units. Some models will have the following alternative colors: brown instead of
black, and blue instead of white. Connect the black (or brown) lead to the phase side of the

-1-

power source, the white (or blue) lead to the common (neutral) side of the power source, and
the green/yellow lead to earth ground.

NOTE

The 120/240VAC Strobe units are designed to operate on both 50 and 60 Hz electrical power.

Special modifications are NOT required for the two different AC line frequencies.

2. DC Models.

The DC units are supplied with two leads, one red and one black. Connect the red (+) lead
to the positive power source terminal and the black (-) to the negative power source
terminal.

NOTE

Polarity MUST be observed for operation.

II. MAINTENANCE.

SAFETY MESSAGE 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 power turned off.

• Any maintenance to the light system must be performed by a trained electrician in accordance
with all applicable national and local codes and standards in the country of use.

• Never alter the unit in any manner. Safety in hazardous locations may be endangered if additional
openings or other alterations are made in units specifically designed for use in these locations.

• The nameplate, which may contain cautionary or other information of importance to maintenance
personnel, should NOT be obscured in any way. Ensure that the nameplate remains readable when
the housing’s exterior is painted.

Failure to follow all safety precautions and instructions may result in property damage, serious
injury, or death to you or others.

A. Flash Tube Replacement.

As strobe lights are used, the flash tubes begin to darken, causing the light output to
decrease.This darkening is characteristic of flash tubes. Darkening will begin near the base of
the tube and progress upward. Also, as flash tubes age, they may have a tendency to misfire
(not fire periodically).

After extended operation, occasionally check for flash tube degradation. Should the flash tube
misfire, have a noticeable decrease in light output, glow continuously or darken to a point
beyond that shown in figure 2 — it should be replaced.

WARNING

High voltages are present inside the light assembly. Wait at least 5 minutes after shutting off the

power before servicing this unit.

To replace the flash tube, proceed as follows:

1. Disconnect power.

2. Remove the lens by removing the two #6 phillips pan head screws. Carefully lift the lens
away from the housing.

3. Grasp the flash tube by its base and pull it out of the socket, using a gentle “rocking”
motion. Install a new flash tube and reassemble the light.

4. Test the light for proper operation.

B.Fuse Replacement.

To replace the fuse, proceed as follows:

1. The fuse is positioned on the component side of the P.C. board, mounted in fuse clips.
For easy removal, pry one end of the fuse out of the clip with an insulated-handled
screwdriver.

2. Replace the fuse with one of the same rating only. The DC 131ST units use a 5-amp, 32­volt, auto type fuse (Federal Part No. K148A142-03), and the DC 131DST units use a

7.5-amp,32 volt, auto type fuse (Federal Part No. K148A142-04). The 120 and 240 VAC
units use a 1-amp, 250-volt, slow blow GMC type fuse (Federal Part No. K148A155-01).

3. Reassemble the light and test for proper operation.

C. Service.

The Federal factory will service your equipment or provide technical assistance with any
problems that cannot be handled locally.

Any units returned to Federal Signal for service, inspection, or repair must be accompanied by
a Return Material Authorization. This R.M.A. can be obtained from the local Distributor or
Manufacturer’s Representative.

At this time a brief explanation of the service requested, or the nature of the malfunction,
should be provided.
