Unpacking the Light Bar
Unpacking the Light Bar
After unpacking the ILS light assembly, inspect it for damage that may have occurred in
transit. If it has been damaged, do not install it. 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. Ensure that the parts listed in kit contents list are
included in the package. If you are missing any parts, contact Customer Support at
1-800-264-3578, 7 a.m. to 5 p.m., Monday through Friday (CT). Disposal of all shipping
materials must be carried out in accordance with national and local codes and standards.
Introduction to the SIFZ Series SpectraLux
The SIFZ SpectraLux® ILS is a single-level LED light bar that mounts on the inside of the
front windshield. It uses ROC (Reliable On Board Circuitry) technology, and Solaris® S2
reflectors. Split, Passenger only, and Driver only are available. The light bar operates at
a nominal input of 13.6 Vdc (11 Vdc minimum). Both Discrete and Serial (Convergence
Network) control are available as configured options.
Discrete models have eight control inputs that connect to the user-supplied low current
switches. Serial models are controlled through the CAT5 serial communication cable.
The cable connects to either a compatible Federal Signal Convergence Network
controller/siren or a Federal Signal Serial Interface Module (P/N 8583446). An internal
PCB assembly within the light bar decodes the control data and performs the requested
function. With the Serial Interface Module, the light bar can be activated by Federal Signal
light bar controllers or individual low current switches.
The backbone is a powder coated aluminum shroud. The light bar has 15-foot power and
ground cables and a 25-foot control cable. Mounting hardware is a configured option.
Refer to mounting instructions supplied with mounting hardware. The light bar has an
operating temperature range of –30 °C to +65 °C (–22 °F to +149 °F).
Selecting Configuration Options for the Serially-Controlled SIFZ
The serial controlled ILS has three configuration options that are selectable with
DIP switches on the light bar control board. The options are described in Table 1 on
page 10.
