WeCan Control Point Module Install

The Whelen Edge Ultra Freedom IV WeCan Lightbar is the perfect lightbar when maximum warning signal and ultimate programmability is required. Whelen’s Freedom IV Series features advanced Linear Super-LED optics, all new DYAD two level technology, and 360° of contiguous light. The F4W lightbar incorporates an anodized extruded heavy duty aluminum base and cover chassis with four Super-LED corner modules. Each corner module has 12 Linear Super-LEDs installed on a conformal coated PCB board with a thermal pad/aluminum bracket heat sink assembly. The outer lens construction consists of two clear Uni-Dome top lenses with a liquid injection molded wiper seal divider for maximum protection against environmental elements. Metal top shields are installed on the Uni-Domes to provide protection from climate conditions and to provide passive solar radiation to direct heat away from internal components.

The F4W has an electronic WeCan Solid-State I/O board that is microprocessor controlled. The I/O board has built-in reverse polarity protection and output-short protection. The I/O board has the ability to flash twenty two Super-LED warning lights. The I/O board shall also have outputs to add takedown, alley lights, and auxiliary lights for each set of lights to be controlled in pairs.

A WeCan control point module is provided that has the ability to program the 18 inputs into the control point data bank using WeCan software. The 18 inputs can be programmed to activate multiple lightbar configuration combinations. The programming software can be downloaded onto a host computer and installed onto the control point via the USB port. All lightheads are installed in the F4W8 with the aid of black polycarbonate snap-in mounting brackets. The lightbar includes a 17 foot, 2 wire, 8 guage unterminated power cable and 17 foot, 17 wire, 22 guage unterminated control cable.

The F4W will have the capability to install a traffic advisor in the rear of the lightbar. An optional photocell is available to automatically dim the F4W8 at night. Additional lights, mount kits, and driver side cable can be installed for an additional cost. Optional color lens filters are available in blue, red, and amber. Optional smoked lenses are available at an additional charge. The F4W includes a permanent mount kit with hardware. All electronic components are covered by a Whelen five year factory warranty.
