Auer Modular Signal Towers



ModulSIGNAL Towers

50mm and 70mm modular warning tower lights

Best of class

High grade, heavy duty and comprehensive, this modular line of 50mm and 70mm diameter signaling towers are flexible and extremely easy to assemble and install. In comparison to competitive products, the SIGNAL50 and SIGNAL70 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. A stainless steel, pole-mount base, set on a zinc diecast metal foot is also available. All poles are offered in several lengths, and may be cut to a specific length if required.

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

All modulSIGNAL tower lights meet UL Type 4 / 4X / 13 and IP65 guidelines for use indoors or out. No other manufacturer offers this extensive range of environmental approvals.

Over 100 combinations of lenses, voltages and illumination types

Variety and interchangeability are standard with both modulSIGNAL lines. Six lens colors and three housing colors are available. Light modules are offered in common voltages. Illumination types include incandescent, LED and strobe. A special flashing LED is also available for increased economy.

sound modules expand Signaling choices

In addition to the many visual alert modules available with the SIGNAL50 and SIGNAL70 lines, Piezo sound modules are also available. Choose from either a single or dual tones.

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
