Best of class

High grade, heavy duty and comprehensive, this 50mm space saving line is flexible and extremely easy to assemble and install. In comparison to competitive products, the SIGNAL50 line offers more features, approvals and options than any other major stack light manufacturer.

Rugged construction for industrial applications

Heavy duty industrial polycarbonate is used to construct all light modules and bases for the SIGNAL50 line. A stainless steel, pole-mount base, set on a zinc diecast metal foot is also available. All poles are offered in seven lengths, and may be cut to a specific length if required.

Three standard bases are offered, including surface mount, pole mount, and side mounting for vertical equipment surfaces and walls. A unique junction box effectively adds three more mounting base choices.

The entire line meets UL Type 4 / 4X / 13 and IP65 guidelines for use indoors or out. No other manufacturer offers this extensive range of environmental approvals.

signal50Over 100 combinations of lenses, voltages and illumination types

Variety and interchangeability are standard with the SIGNAL50 line. Six lens colors are available (green, red, amber, blue, yellow and clear), more than any other major manufacturer. Light modules are offered in four voltages. Illumination types include incandescent, LED and strobe. A special flashing LED is also available for increased economy.

New sound module expands choices

In addition to the many visual alert modules available with the SIGNAL50 line, a new Piezo sound module is now available. Choose from either a single or dual tone alert in a gray or black housing.

Easy assembly, changeout and maintenance

Up to five modules of the same voltage may be combined in any order with a simple twist of the wrist. Each light module has a bayonet locking system and finger protection that allows it to be “hot swapped” if necessary. With reassembly of the Warning Tower, all modules are under power again, automatically. To prevent unauthorized opening, optional set screws may be used to lock each module in place.
