SAFETY MESSAGE TO INSTALLERS

OF

FEDERAL SIGNAL LIGHT SYSTEMS

People’s lives depend on your safe instal­lation of our products. It is important to
read, understand and follow all instructions
shipped with the products. In addition, listed
below are some other important safety in­structions and precautions you should follow:

• To properly install a light assembly: you must
have a good understanding of automotive
electrical procedures and systems, along with
proficiency in the installation and use of safety
warning equipment.

• When installing equipment or wiring inside air
bag equipped vehicles, the installer MUST en‑
sure that the equipment or wiring is installed
ONLY in areas recommended by the vehicle
manufacturer. Failure to observe this warn‑
ing will reduce the effectiveness of the air bag,
damage the air bag, or potentially damage or
dislodge the equipment, causing serious injury
or death to you or others.

• When drilling into a vehicle structure, be sure
that both sides of the surface are clear of any‑
thing that could be damaged.

• A light system is a high current device. In
order for it to function properly, a separate
ground connection must be made. If practical,
it should be connected to the negative battery
terminal. At a minimum, it may be attached
to a solid metal body or chassis part that will
provide an effective ground path as long as the
light system is to be used.

• Locate light system controls so the VEHICLE
and CONTROLS can be operated safely under
all driving conditions.

• This product contains high intensity LED de‑
vices. To prevent eye damage, DO NOT stare
into the light beam at close range.

• You should frequently inspect the light system
to ensure that it is operating properly and that
it is securely attached to the vehicle.

• File these instructions in a safe place and refer
to them when maintaining and/or reinstalling
the product.

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

I. UNPACKING.

After unpacking the Arjent S2 lightbar, inspect it for
damage that may have occurred in transit. If the unit has
been damaged, file a claim immediately with the carrier,
stating the extent of damage. Carefully check all envelopes,
shipping labels and tags before removing or destroying
them.

II. DESCRIPTION.

The Arjent S2 lightbar is available in either a 36”, 44”
or 53” length and operates on a nominal input of 13.6 volts
DC (11 volts DC minimum). Clear polycarbonate bases
along with clear or colored polycarbonate domes house a
multi‑channel programmable (via serial interface module)
circuit board assembly within the bar. The multi‑channel
PCB assembly is connected in turn to additional multiple
circuit board panels, each having the availability of 4 to 5
maximum factory‑installed options per panel. The lightbars
have an operating temperature range of ‑30°C to +65°C
(‑22°F to +149°F). They may be mounted with a hook,
permanent, or flat mounting kit to the vehicle. Available
built to order options on the Arjent S2 include:

Panelized Solaris LED Options:
XD1LC6‑A, ‑R, ‑B, ‑W, ‑G: 6‑button Solaris S2 LED
light head
XDALED‑A, ‑R, ‑B, ‑W, ‑G: 3‑button Solaris S2 LED
light head, alley light position (factory default at front
light cutoff)

• Flashing pattern selectability of the LED options
may be specified via programming of the lightbar.
See table 2.

• SignalMaster operation is accomplished via
programming of the lightbar.
4‑pos. SignalMaster available on the 36” bar;
6‑pos. SignalMaster available on the 44” bar;
8‑pos. SignalMaster available on the 53” bar

• Steady‑burn availability of 1 or 2 front LED
heads must be specified via the Arjent S2 initial
order entry.

Panelized Halogen Options (maximum of 6 per
lightbar):
XDAHAL Alley Light, 35 watts/head (MR 11)
adjustable
XDTD Takedown Light 50 watts/head
XDWL Work Light 50 watts/head

• Flashing of the halogen options is accomplished via
programming of the lightbar.

Mounting Options:
XAHKN‑SC, XAHK‑SC Hook Mount, Neutral or
Black
XAPKN‑SC, XAPK‑SC Permanent Mount, Neutral
or Black
XAFM Flat Mount

NOTICE

Improper warning system and/or two‑way radio
system operation may result if a two‑way radio
antenna is installed on, or within 18‑inches of, the
lightbar. Before permanent installation of the light‑
bar or a two‑way radio antenna, test the warning
system and two‑way radio system. DO NOT install
a two‑way radio antenna on the lightbar.

Some installations may require relocation of the
two‑way radio antenna to a trunk or fender loca‑
tion.

Warning system failure may result if additional
holes are drilled in the lightbar, or if auxiliary
devices are installed on the lightbar. DO NOT drill
additional holes in the lightbar, or install auxiliary
devices on the lightbar.

The lightbar is completely wired at the factory and
does not require any additional internal wiring; two 10
AWG power conductors (red and black) and the CAT5
communication cable exit the lightbar. All the conductors
necessary for control of any and all basic and optional
functions are contained in the CAT5 cable.

The basic light functions of the unit are communicated
via the CAT5 cable. The cable connects to either a
compatible Federal Signal Serial control head, or, a Federal
Signal Serial Interface Module.

Before proceeding, ensure that the lightbar has
been installed on the vehicle roof in accordance with the
instructions packed with the mounting kit.

Figure 1. Block Wiring Diagram.

D. SignalMaster Option.

Each lightbar is equipped for SignalMaster
operation via an external control unit or control leads on
the Interface Module (refer to paragraph III.F.). When
SignalMaster operation is not initiated, the SignalMaster
heads will flash per the selected Mode for additional light
indication to the rear.

The SignalMaster function is completely
configured at the factory and does not require any
additional wiring inside the light bar. All conductors
necessary for control of the SignalMaster is via the
compatible Serial communication control head or the
FSC #8583446 Serial Interface Module. For wiring and
operation instructions, refer to the instruction sheet
packed with the applicable control head or the FSC
Serial Interface Module’s Instruction sheet (part number

2562248).

Light system controls must be located so that
VEHICLE and CONTROLS can be operated
safely under all driving conditions.

A. See figure 1. From the lightbar, route the CAT5
control cable into the vehicle’s cab or trunk near the
eventual location of the compatible Federal Signal Serial
control head or FSC #8583446 Interface Module. An input
cable is also provided with the FSC #8583446 Serial
Interface Module.

Reverse polarity may damage any power supply
and prevent operation. Ensure that correct polarity
is observed. Unit must be fused at the source.

B. Connect the separate 10 gauge black lead to the
vehicle battery ground (‑) terminal.

C. Route and connect the 10 gauge red lead through
the supplied 40A fuse, fused at the source, to the BAT+
terminal.

E. Light Bar Controls.

The Arjent S2 functions are communicated via
the serial cable. Both the Federal Signal control head
and the Serial Interface Module are capable of providing
the following controls to the lightbar. For programming
options, refer to the Installation Manual shipped with the
Interface Module or the Federal Signal Control Head.
