with Same Light Module

SIGNAL50 warning tower lights are the perfect compliment
to any industrial control system. High grade, heavy duty and
comprehensive, this 50 mm space saving line is also flexible and
extremely easy to assemble and install.

Best of Class

In comparing SIGNAL50 warning tower lights to competitive
products from manufacturers including Patlite, IDEC, Federal Signal
and Werma, the SIGNAL50 line offers more features, approvals and
options than any of these major stack light manufacturers.

All models

shown smaller

than actual size.

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, pole­mount base, set on zinc die-cast metal foot is also available. The entire
line meets UL Type 4/4X/13 and IP65 guidelines for use indoors or
out. No other manufacturer of competitive product offers this extensive
range of environmental approvals.

Over 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 different voltages including 12 and 24 Vac/Vdc, 120 and
240 Vac. Illumination types include incandescent, LED and strobe. A
special flashing LED is also available.

Assembling a Stacklight System

1. Select a Base Unit

A variety of base units are available. Bases include a mounting foot, extension tube and
pole cap, or you can use a horizontal or vertical flush mount base.

2. Select Up to Five Light Modules

Light modules are available in a variety of colors in either steady, steady flashing or Xenon strobe
configuration. Incandescent or LED light sources are available. The incandescent lights are lower
cost and brighter than the LEDs, however, the LEDs have a greater bulb life. You may use up to
5 light modules or 4 light modules and one single circuit or 3 light modules and one dual circuit
sound module.

3. Select Incandescent or LED Lamp Bulbs

Please match the LED color to the light module color. Also note the Xenon strobe modules
include bulbs.

4. Optional Sound Module

The single circuit bi-tonal sound module may be used with up to 4 light modules. The dual circuit
sound module may be used with up to 3 light modules.

5. Choose an Optional Junction Box

The plastic foot pole bases mount on top of the junction box to facilitate circuit wiring.
