III. INSTALLATION.
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.
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.
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).
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.
