Introduction
The Latitude SM is an addition to Federal Signal’s family of SignalMaster directional lights. Equipped with
three LEDs per position and Federal Signal’s Solaris® LED reflectors, the Latitude SM delivers an impressive
optical performance for your vehicle. Meeting Class 1 specifications and available for both interior and exterior
mounting, the Latitude SM is suitable for many vehicle applications.
This directional light is available in six-head and eight-head versions. These models come equipped with the
Federal Signal economy SignalMaster control that allows users to easily install and operate built-in directional
signals of left, right, and center-out.
In addition to the three built-in directional signals, an additional warning mode can be activated by applying
+12 Vdc simultaneously to the Red, White, and Green wires and -GND to the Black wire. A 75 FPM pattern is
the only available pattern. To activate the mode, an additional, installer supplied, switch required. This mode
has the highest priority. When not in flashing mode and power is on the red wire, applying power to the green
or white wire gives the corresponding left or right arrow priority over the center out mode.
Unpacking the Product
After unpacking the product, inspect it for damage that may have occurred in transit. If it has been damaged,
do not attempt to install or operate it. File a claim immediately with the carrier, stating the extent of damage.
Failure to identify damage before installation could lead to rejection of any claim. Carefully check all
envelopes, shipping labels, and tags before removing or destroying them. Ensure that the parts listed in
Table1 are included in the package. If you are missing any parts, contact Federal Signal Customer Support at

Mounting the Light Bar
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the deployment path of an airbag.
Failure to observe this warning will reduce the effectiveness of the airbag or potentially dislodge the
equipment, causing serious injury or death.
LIGHT OUTPUT COMPLIANCE: This product is intended for supplemental warning and for use in
conjunction with an approved primary warning light system. Consult local codes and regulations to
determine if the power supply / light head combination complies with the horizontal or vertical mount
position desired in your application. Failure to follow this caution could result in reduced light output
and reduced warning system effectiveness.
WATER DAMAGE PRECAUTION: When installing the Latitude on the exterior of a vehicle, ensure that
it is mounted with the bottom channel facing down (Figure 1). Failure to follow this precaution may
cause water to enter the light bar and damage the circuitry.
To mount the light bar:
1. Determine which side of the light bar to secure to the mounting surface. From a horizontal orientation, the
bottom and rear surfaces of the light bar are available for mounting.
2. Locate the opening in the selected mounting-bolt channel and drop in four mounting screws. See Figure 1.
Figure 1 Light bar positioned horizontally with mounting hardware
DRILLING PRECAUTIONS: When drilling holes, check the area you are drilling into to ensure that you
do not damage vehicle components while drilling. All drilled holes should be de-burred, and all sharp
edges should be smoothed. All wire routings going through drilled holes should be protected by a
grommet or convolute/split loom tubing.
3. Drill holes as needed for the mounting screws.
4. Secure the light bar to the mounting surface using the supplied nuts.

HIGH CURRENT ARCING: Do not connect this system to the vehicle battery until ALL other electrical
connections are made, mounting of all components is nished, and you have veried that no shorts
exist. High current conductors can cause hazardous sparks or burning wire, resulting in electrical
res.
PCB DAMAGE/IMPROPER WIRING: Improper wiring of the illuminated switch feature will result in
printed circuit board damage. Ensure that the chassis ground lead is connected to the gold (pin 3)
terminal and that the unterminated end of the lead is connected to a known good chassis ground.
To wire the illuminated ON/OFF switch:
1. Connect the right-angle terminal on the ground lead of the switch bracket to the gold terminal (Pin 3) of the
ON/OFF switch. See Figure 3.

2. Route the unterminated end of the ground lead to a known good chassis ground.
3. Cut the lead to length and crimp the supplied ring terminal on the lead. If necessary, additional 18 AWG
wire may be spliced to the ground lead.
4. Secure the lead to the chassis ground with a user-supplied screw.
Inspection and Final Installation
To complete and verify that the light bar and control head work properly:
1. Ensure that there are no loose wire strands or other bare wires that may cause a short circuit. All wires
must be protected from any sharp edges that could eventually cut through the insulation.
2. Connect the 18 AWG red wire to the (+) positive terminal of the battery using an in-line, user-supplied
10A fuse and fuseholder. To protect the entire length of the wire, locate the fuse as near to the battery as
possible.
NOTE: If the leads of the power supply are reversed, all directional lamps will light simultaneously. Correct
the wiring before proceeding.
3. Read and understand the operation instructions and test the lights for proper operation of all functions.
