What environments are IP69K products suitable for?

IP69K products are ideal for applications in Food and Beverage, Wastewater, Pharmaceutical, Marine, Medical Facilities, and Medical Equipment Manufacturing.

How is IP69K different from NEMA Type 4?

IP69K protects against low volume, high temperature, high pressure water jets at short distances (6 inches max), while NEMA Type 4 protects against high volume, low pressure water at long distances (10-12 feet).

What are the testing conditions for IP69K products?

Products are dust-tight tested and undergo high-pressure steam jet cleaning with water sprays of 1160–1450 psi from 4 angles at 4–6 inches distance and 176°F (80°C).

What certifications do Federal Signal IP69K products hold?

In addition to IP69K, Federal Signal products meet or exceed standards of UL, CSA, CSFM, IECEx, and other global certifications, and the company is ISO 9001 Certified.

What is the difference between IP69K and NEMA Type 4?

IP69K offers dust-tight protection from close-range, powerful, high-temperature water jets. NEMA Type 4 provides dust-tight protection from high-volume, low-pressure water from longer distances.

How to Install the 151XST-240C Strobe Light

This guide provides step-by-step instructions for installing and wiring the 151XST-240C 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 Strobe Light

    Carefully unpack the strobe light and inspect it for any damage that may have occurred during transit. If damaged, do not install and file a claim with the carrier.

  2. Mount the Strobe Light

    Choose a suitable location for mounting. For pipe mounting, ensure threads are clean, apply conductive sealant to the threads, and secure the light to a 3/4-inch NPT pipe using the set screw. For surface mounting, use the mounting base as a template to mark and drill holes, then secure the light with installer-supplied hardware.

  3. Wire the Strobe Light

    Ensure power is off before wiring. 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. Replace the dome assembly securely.

  4. Test the Strobe Light

    After wiring, restore power to the strobe light and test it to ensure proper operation. Verify that the light flashes as expected.
