Unpacking the Product
Each IMPAXX
®
comes with the mounting hardware shown in
Figure 1 on page 13. After unpacking the IMPAXX Series LED
Lights and mounting hardware, inspect them for damage that
may have occurred in transit. If a product has been damaged, do
not attempt to install or operate it. File a claim immediately with
the carrier, describing the extent of damage. Carefully check all
envelopes, shipping labels, and tags before removing or destroying
them.
An Overview of the IMPAXX Series LED Light Heads
The IPX3 IMPAXX Series LED Light Heads are fully sealed, low-
current warning lights that can be mounted on the inside or outside
of the vehicle. IMPAXX uses Solaris
®
LED reflector technology to
provide a bright and effective secondary warning signal. IMPAXX
models have three LEDs that are either amber, blue, green, red,
or white with a clear lens. The IMPAXX can also be ordered with
colored lenses that match the LED color.
LEDs are available in enhanced off-axis or focused configurations.
IMPAXX has an internal flashing circuit with 23 selected flash
patterns, including a steady burn pattern for use with an external
flasher. Patterns are selected by touching a pattern-selection wire
to ground (−GND).
Light heads can be set to synchronize, synchro-shift, or both.
The synchronize/synchro-shift feature is fully compatible with the
Federal Signal Viper S2 warning lights. IMPAXX also has several
floating-synch pattern sets that are within one flash per minute of
each other. See Table 2 on page page 16. If one light is set at
74 FPM and another at 75 FPM, for example, the lights appear to
migrate in and out of synchronization.
All IMPAXX models are designed for use with all Federal Signal
switch controllers. The IMPAXX light head is supplied with a black
polycarbonate bezel, a rubberized gasket, and mounting hardware
for surface mounting. The IMPAXX has an operating temperature of
−22˚F to +176˚F (−30˚C to +80˚C).
