Frequently Asked Questions

What does the IP69K rating signify?

The IP69K rating is the highest standard for ingress protection, indicating a product can withstand high-pressure, high-temperature washdowns and is dust-tight.

Where are IP69K products typically used?

IP69K products are ideal for applications in food and beverage, wastewater, pharmaceutical, marine, medical facilities, and medical equipment manufacturing.

How does IP69K differ from NEMA Type 4?

IP69K protects against high-pressure, high-temperature water jets at short distances (6 in max), while NEMA Type 4 handles high volume, low pressure water at longer distances (10–12 ft).

How does IP69K protect against water jets?

IP69K products are protected from close-range, powerful, high-temperature water jets, tested with sprays of 1160–1450 psi at 176°F (80°C) from 4–6 inches.

What is the dust protection level of IP69K?

IP69K ensures no ingress of dust is permitted, as products are dust-tight and tested in an Arizona A2 Dust chamber for five hours.

What are the benefits of using IP69K products?

Using IP69K products helps reduce failures from water/dust ingress, thereby increasing productivity and decreasing production downtime.

What certifications do Federal Signal products hold?

Federal Signal products meet or exceed UL, CSA, CSFM, IECEx, and other global certifications, and the company is ISO 9001 Certified.

How to Install the 151XST Series Strobe Light

This guide provides step-by-step instructions for installing and wiring the 151XST Series Strobe Light in hazardous conditions.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Conductive sealant

  1. Unpack and Inspect the Light

    Carefully unpack the strobe light and inspect it for any damage. If damaged, do not install and file a claim with the carrier.

  2. Mount the Strobe Light

    For pipe mounting, clean the mating threads and apply conductive sealant. Thread the light onto a 3/4-inch NPT pipe and secure it with the set screw. For surface mounting, use the mounting base as a template to mark and drill holes, then secure the light with supplied hardware.

  3. Wire the Strobe Light

    Ensure power is off. For AC models, connect the black lead to the hot side and the white lead to the neutral side of the power source. For DC models, connect the red lead to the positive side and the black lead to the negative side. If necessary, connect the green screw to an earth ground.

  4. Secure the Dome Assembly

    After wiring, replace the dome assembly by twisting it clockwise until secure.

  5. Test the Strobe Light

    Connect power to the strobe light and test it to ensure proper operation. Verify that it flashes as expected.
