CTL70 LED signal towers provide one to five fixed color layers in a nominal 70mm body. Select steady, flashing or selectable light, an intermittent beep or siren option, and a disc, side-nut or square-folding mounting base.
SMD LEDs illuminate prism-pattern PC lenses above an ABS base. High-brightness LED components have a typical life reference above 50,000 hours; this does not specify complete-assembly service life. The five listed color stacks are fixed configurations and cannot be freely rearranged.

DC power values are rounded calculations from nominal voltage and maximum channel current. AC power and current are separate specifications. These color-channel figures do not establish the total consumption of every stack and sound combination.

External contacts control the individual light and sound circuits. Use the supply and polarity arrangement for the selected version. An open mode jumper selects flashing; fitting the link selects steady illumination.
To remove a lens module, turn counterclockwise until its marks align, then lift it off. For assembly, align the marks, press downward and turn clockwise until the triangular mark reaches the index.
The cable outlet must not face upward. Regular IP43 configurations require upright vertical mounting because their water protection is below IPX4. Use the fixing pattern of the selected bracket and tighten the mounting hardware.
Disconnect power before installation, wiring, work on the assembly or maintenance. Check the selected model and rated supply, secure the installation, keep conductive dust and liquid out, and protect wiring against impact and abrasion. Complex faults and high-voltage components require qualified service personnel.
These products are intended for industrial signaling. High-reliability infrastructure, personal-safety functions, harsh environments, fire or explosion hazards, military uses and aerospace projects require a specifically designed and expressly confirmed configuration.
